SleekFlow Alternatives 2026: 7 Whitelabel WhatsApp CRMs for Agencies

I keep meeting agency owners who tell me the same story about SleekFlow. They liked the omnichannel pitch, signed up for a couple of seats, and then six months later realised three things at the same time. The HKD per-user pricing was eating their gross margin. They couldn’t put their own brand on it for the agency’s SMB clients. And the platform’s strongest features were locked behind the Premium AI plan that started at HK$579 per user per month (~₹6,250 per user per month at the time of writing). None of that is a SleekFlow bug — it’s how SleekFlow built the product. But if you’re running a 5–50 person digital agency in India, the UAE, the Philippines, or anywhere outside Hong Kong’s home market, that price ladder reads very differently than it does at SleekFlow HQ.

So you start searching for SleekFlow alternatives. Which is why you’re here.

I’m Rakshit Soni, co-founder of Lion CRM, a WhatsApp CRM Chrome extension built by LotsOfCode Private Limited for both end-users and whitelabel agency resellers. I’ve spent the last four years helping agencies and SaaS founders pick the right WhatsApp CRM stack for their reseller business — and I’ve watched a dozen SleekFlow refugees do the same exit math. This guide is what I’d hand a Vikram-style agency owner the day they tell me SleekFlow stopped working for them. (If you’d rather watch than read, our LotsOfCode YouTube channel has the same arguments in video form.)

We’ll go through what SleekFlow does well, where it leaves agency resellers stranded, then walk seven realistic alternatives in 2026 — from the whitelabel-first option (Lion CRM) to the BSP-locked ones (Wati, AiSensy, Interakt) to the omnichannel-similar ones (Respond.io, Trengo). I’ll include rupee pricing math for a 25-customer agency scenario, a side-by-side comparison table, an honest verdict on which alternative fits which agency profile, and a 7-step migration playbook for the agencies that decide to switch.

Why agencies are searching for SleekFlow alternatives in 2026

When I look at the top SleekFlow refugees who landed on Lion CRM in the last twelve months, four reasons come up again and again:

1. The per-user pricing math doesn’t survive an INR resale. SleekFlow’s Pro AI plan is HK$399/user/month with a 3-user minimum, and the Premium AI plan is HK$579/user/month with a 5-user minimum. Convert that to rupees at the time of writing (₹10.80/HKD) and a 5-seat Premium AI team is roughly ₹31,000/month before WhatsApp conversation costs. For an agency reselling at ₹2,499–₹4,999/month per SMB client, that single fixed cost wipes a huge chunk of gross margin before the first message is sent.
2. There’s no whitelabel programme. SleekFlow has an affiliate/partner programme, not a whitelabel one. You can earn a commission on referrals. You cannot rebrand SleekFlow as your own product and resell it under your agency’s name. For a Vikram-style 10-person agency in Bangalore that needs a subscription-revenue product to upsell to SMB clients, that’s the deal-breaker.
3. BSP lock-in for everything important. SleekFlow’s WhatsApp side runs through the WhatsApp Business Platform (Cloud API + on-premises) as a BSP. That’s great for compliance, but it means every WhatsApp conversation has a per-conversation Meta fee on top of the subscription, every template message needs Meta approval, and every WABA your clients use is hosted under SleekFlow’s BSP relationship — not yours. Agencies that want their own Meta tech-provider relationship have to start over with a different stack.
4. The AI bundle is the only way to get the good features. Conversational flows, AI agents, advanced analytics, and the better automation features are concentrated in the Premium AI plan. So agencies that want the automation without the per-user AI cost end up paying for AI they’re not using yet — or losing features they actually need.

If any of those four reasons sound like your last month, the rest of this guide is for you. Let’s compare the realistic alternatives.

What SleekFlow does well (so you know what you’re giving up)

I’m not here to trash SleekFlow. It’s a legitimately good product if you happen to be the type of business it was built for — and being honest about that is part of picking the right alternative.

SleekFlow’s omnichannel inbox is one of the cleanest in the WhatsApp + Instagram + TikTok + SMS + email category. The AI agents on the Premium plan handle real revenue-driving conversations (booking, qualification, follow-up) with surprisingly little prompting work. Their reporting layer is genuinely better than most Indian BSPs, and their support team responds in business hours that overlap most of Asia-Pacific. SleekFlow’s claim of 2,000+ businesses and 1M conversations per day isn’t marketing fluff — it’s a real platform with real volume.

So if you are a single B2C brand with 5–50 seats, plenty of margin per customer, and no plan to resell the platform to anyone else, SleekFlow is a reasonable pick. The alternatives below are for the other case — the case where you’re an agency, a regional SaaS founder, or a digital marketing shop that needs subscription revenue from your own SMB clients.

SleekFlow pricing decoded: the HKD math agencies miss

Let’s run the actual numbers on SleekFlow first, so the alternatives have something to be compared against. At the time of writing, SleekFlow’s published pricing is:

• Free — HK$0/month. 3 user accounts. 200 free messages. Limited features.
• Pro AI — HK$399/user/month. Minimum 3 users (HK$1,199/month total). Each additional user HK$199/month. Adds basic automation, AI assist, inbox routing.
• Premium AI — HK$579/user/month. Minimum 5 users (HK$2,859/month total). Each additional user HK$199/month. Adds AI agents, full flow builder, advanced reporting.
• Enterprise — Custom. SSO, dedicated CSM, custom contracts.

WhatsApp hosted phone numbers are extra at US$15/month per number (roughly ₹1,250/month) on paid plans, and Meta’s per-conversation fees pass through on top of the SleekFlow seat cost.

A 5-seat Premium AI team at HK$2,859/month converts to roughly ₹30,900/month in subscription alone, before Meta’s conversation pass-through. A 10-seat Pro AI team at HK$1,199 + 7 × HK$199 = HK$2,592 converts to roughly ₹28,000/month. For most Indian agencies, that’s already 2× what a comparable Indian BSP charges and 4–6× what an unlocked Chrome-extension stack costs.

For Vikram, who wants to resell a whitelabel WhatsApp CRM to his 25 SMB clients at ₹2,499–₹4,999/month each, those SleekFlow numbers are the reason he’s on this page. The good news is — there are real alternatives that solve both the price problem and the whitelabel problem. Here they are.

The 7 best SleekFlow alternatives for whitelabel WhatsApp CRM in 2026

I picked these seven because they each win on at least one dimension a Vikram-style agency cares about (whitelabel programme, INR pricing, channel coverage, ease of migration), and because each of them is an actually-active product in 2026 — not a parked domain or a dead brand. Lion CRM is first because it’s the only one that solves both the whitelabel and the per-user pricing problem at the same time. The rest are ordered by how often I see them on agency shortlists.

Alternative #1: Lion CRM — the whitelabel WhatsApp CRM SleekFlow won’t be

Lion CRM is a WhatsApp CRM Chrome extension built by LotsOfCode Private Limited. Architecturally it’s the opposite of SleekFlow: it doesn’t sit on Meta’s Cloud API as a BSP. Instead it layers on top of your client’s own WhatsApp Web session inside their browser, with 100% local data storage on the user’s device. Nothing flows through a third-party BSP server because there is no BSP in the loop.

For an agency reseller, that architecture matters for two reasons. First, you skip Meta’s per-conversation fees entirely — your client’s own WhatsApp account is doing the sending, the way it always has. Second, you get a real whitelabel programme. You pick a plan (Starter, Growth, or Enterprise) at admin.lioncrm.com, fill in your brand name, logo, colors, support number, and your own website URL, and download a Chrome extension that ships with your agency’s branding. Your SMB clients install your extension and never see Lion CRM anywhere.

Pricing for end-users (when you want to test it yourself): ₹99 for the first month special, ₹299/month after that, or ₹2,360/year (~₹197/month). A 7-day free trial auto-activates the first time you install the Chrome extension — no credit card needed. Pricing details and plan comparison live on the pricing page.

Pricing for agency resellers: Whitelabel plans start at the Starter tier (small per-user-per-month fee, fits 5-client agencies), Growth tier (mid-size agencies, 25 clients), and Enterprise (larger). You pay the tier fee plus per-user-per-month for active licenses, and you resell at your own price — ₹2,499/month, ₹4,999/month, ₹9,999/month, whatever your market supports. Margin economics are the part SleekFlow can’t match: at 25 SMB clients reselling at ₹2,999/month, an agency that pays roughly ₹1,000/active-user/month to Lion CRM keeps approximately ₹50,000/month in gross margin after platform cost, compared to negative margin if you’d tried to resell SleekFlow Premium at the same retail.

If you’d rather start with the agency reseller flow, the LotsOfCode YouTube channel has walkthroughs of the whitelabel admin panel and the branded-extension build process. For WhatsApp questions, Kuldeep (co-founder, partnerships) is reachable at +91 74260 34448.

Where Lion CRM is honest about its limits. Because it’s a Chrome extension on WhatsApp Web, it does not give you a BSP relationship with Meta. If your client specifically needs the WhatsApp Business Cloud API for compliance (e.g., a regulated bank or insurance use case that requires template messages with Meta-approved delivery receipts), Lion CRM is not the right fit — you need a Wati/AiSensy/Interakt-class BSP for that workload. Lion CRM serves the 80% of SMB WhatsApp use that doesn’t need a BSP, at the price point and whitelabel depth that BSPs can’t match.

Alternative #2: Respond.io — omnichannel sibling without whitelabel

Respond.io is the SleekFlow alternative most agencies look at first because it’s structurally the closest substitute: Malaysian-headquartered BSP, omnichannel inbox covering WhatsApp + Instagram + Facebook + Telegram + SMS + email, and a flow builder for routing and automation. The product is fast, the AI agent layer (Respond.io AI) shipped in 2024 and is mature, and the company has a real customer count to point at.

Pricing starts at the Starter plan at US$79/month for 10 users and 1,000 monthly active contacts, with the Team plan at US$159/month and the Business plan at US$249/month. WhatsApp Cloud API per-conversation fees pass through on top.

For a 25-customer agency, the per-customer-equivalent fee on the Business plan works out to roughly ₹830/customer/month before Meta fees, which is more competitive than SleekFlow but still doubles or triples what a Chrome-extension stack costs.

The agency catch: Respond.io, like SleekFlow, has no whitelabel programme. There’s a partner programme that pays a referral commission, but you cannot rebrand Respond.io as your agency’s product. So if pure cost is your concern and you’re happy reselling someone else’s brand to your SMB clients, Respond.io is a solid pick. If you want subscription revenue under your own brand, this one doesn’t solve the problem.

Alternative #3: AiSensy — INR pricing, no rebrand

AiSensy is the most popular Indian BSP at the SMB price point, and the SleekFlow alternative most agencies land on when they pivot from we want omnichannel to we just want WhatsApp at INR prices. Pricing starts at ₹999/month (Basic), ₹2,399/month (Pro), and ₹4,999/month (Pro+) per WABA number. The Basic plan covers 500 free service conversations; the Pro plan adds the Click-to-WhatsApp ads connector, agents, and the Drag-and-Drop chatbot.

AiSensy’s pitch to agencies is simple INR pricing and an Indian support team. For a 25-customer agency, the per-customer-equivalent fee on the Pro plan is roughly ₹95/customer/month — dramatically cheaper than SleekFlow. WhatsApp Cloud API per-conversation fees pass through on top, and Meta’s January 2026 conversation pricing hike (the one that moved utility conversations from free to paid) hit AiSensy users the same way it hit every BSP.

The agency catch (same as Respond.io): AiSensy has no whitelabel programme either. Agencies resell AiSensy under the AiSensy brand and pocket a referral commission. If you can live with that — meaning your SMB clients see a Powered by AiSensy footer in the UI — AiSensy is fine for INR-sensitive Indian agencies. If you want your own brand visible end-to-end, look at Lion CRM (above) for whitelabel or pair AiSensy with a separate frontend.

Alternative #4: Wati — Indian BSP, mid-market staple

Wati is the older, larger, mid-market Indian BSP that SleekFlow’s enterprise customers most often compare against. Pricing is roughly US$49/month (Growth, 5 users), US$98/month (Pro, 5 users), and US$259/month (Business, 5 users), with extra users at US$15-25/seat/month. WhatsApp Cloud API per-conversation fees pass through on top.

Wati’s strengths are a polished UI, a long-standing Shopify and WooCommerce ecosystem, and integration depth (Zapier, Make, native HubSpot connector). It’s a serious product, and for a single-brand B2C operator with 50-200 customers and a real e-commerce stack, Wati is a more mature pick than SleekFlow.

The agency catch: Wati has a partner programme with a commission structure but no public whitelabel programme. Their enterprise team does close one-off whitelabel-style deals, but you’re negotiating individually and the floor on those deals is well into the multi-thousand-dollar-per-month range. For a 10-person digital agency in Bangalore, Wati is too expensive to use as a hidden infrastructure layer.

Alternative #5: Interakt — Razorpay-anchored INR BSP

Interakt is the Razorpay-owned WhatsApp Business API platform that sits in the same INR-price BSP bracket as AiSensy. Pricing starts at ₹999/month (Starter) and ₹2,499/month (Growth), with the Advanced plan around ₹4,999/month. WhatsApp Cloud API per-conversation fees pass through on top.

Interakt’s strength is the Razorpay integration — for any agency whose SMB clients already accept payments through Razorpay, the Interakt-Razorpay combination removes a lot of friction (payment links, order confirmation, abandoned cart recovery, automatic invoice messages). The product itself is younger than Wati but matured significantly in 2024-2025.

The agency catch: Interakt also has no public whitelabel programme. The Razorpay-owned distribution channel is the moat, not the agency reseller channel. As with AiSensy and Wati, you can resell Interakt as a referral partner, but your SMB clients will see Interakt branding inside the dashboard.

Alternative #6: DoubleTick — India mobile-first

DoubleTick is the India-headquartered WhatsApp Business platform with the strongest mobile-first story. The product runs on mobile + web with a Postman-like API explorer for technical clients, and pricing is in the ₹999-₹3,999/month range across Starter, Pro, and Premium plans. Same BSP pattern as AiSensy and Interakt: Cloud API on Meta, per-conversation fees pass through.

DoubleTick differentiates on speed (the mobile app is genuinely faster than most BSP dashboards) and on a slightly more developer-friendly API layer than AiSensy. For agencies whose SMB clients live in WhatsApp on phones (not at desks), DoubleTick is a stronger pick than the desktop-first BSPs.

The agency catch: DoubleTick, predictably, has no public whitelabel programme either. You can be an affiliate; you cannot rebrand. The mobile-first story is the differentiator, not the agency-economics story.

Alternative #7: Trengo — European omnichannel, premium price

Trengo is the European omnichannel inbox that occasionally shows up on SleekFlow shortlists when an agency wants AI-assisted customer service across WhatsApp + email + voice + Instagram, with GDPR-first data residency in the EU. Pricing starts at €99/month (Essentials, 5 users), €159/month (Boost), and €249/month (Pro), with WhatsApp Cloud API per-conversation fees on top.

Trengo’s strength is the European compliance posture (EU data residency, GDPR-first defaults), AI assistants (HelpMate) that match SleekFlow’s AI agent layer feature-for-feature, and voice channels for agencies that need a phone+chat unified stack. If your agency’s clients are based in the EU and need a single inbox for chat and email, Trengo competes with SleekFlow head-on.

The agency catch: Same as the others — partner commissions yes, whitelabel programme no. And the EUR pricing is even less friendly for an INR resale than SleekFlow’s HKD pricing.

SleekFlow alternatives compared: pricing, whitelabel, channels

Here’s the side-by-side, with numbers at the time of writing. INR conversions use ₹10.80/HKD, ₹83/USD, ₹93/EUR.

Platform	Starting price (entry plan)	INR equivalent	WhatsApp BSP / direct?	Whitelabel	Best fit
SleekFlow	HK$1,199/month (3 users, Pro AI)	~₹13,000/month	Cloud API BSP	Affiliate only	Single B2C brand, 5-50 seats, APAC
Lion CRM (whitelabel)	Starter tier + per-user-per-month	~₹4,000-₹10,000/month start	Chrome extension on WhatsApp Web (no BSP)	Yes (Starter / Growth / Enterprise)	Agencies + SaaS resellers, 5-100 SMB clients
Respond.io	US$79/month (Starter, 10 users)	~₹6,500/month	Cloud API BSP	Affiliate only	APAC/global B2C, omnichannel
AiSensy	₹999/month (Basic)	~₹999/month	Cloud API BSP	Affiliate only	Indian SMBs, INR-sensitive
Wati	US$49/month (Growth, 5 users)	~₹4,070/month	Cloud API BSP	Negotiated only	Mid-market e-commerce, Shopify-heavy
Interakt	₹999/month (Starter)	~₹999/month	Cloud API BSP	Affiliate only	Razorpay-anchored Indian SMBs
DoubleTick	₹999/month (Starter)	~₹999/month	Cloud API BSP	Affiliate only	India mobile-first SMBs
Trengo	€99/month (Essentials, 5 users)	~₹9,200/month	Cloud API BSP	Affiliate only	EU agencies, GDPR-first

The single column that matters most for an agency is Whitelabel. Six of these eight options give you a referral commission. One — Lion CRM — gives you a rebranded product you actually sell. SleekFlow itself is in the affiliate column, which is the whole reason you’re reading this guide.

INR pricing math: 25-customer agency scenario across all 7

Here’s the agency math, modeled on a Vikram-style scenario: 10-person Bangalore agency, 25 SMB clients each paying the agency ₹2,999/month for a WhatsApp CRM service, agency wants to keep ≥₹50,000/month gross margin after platform cost. WhatsApp conversation costs from Meta are excluded from each row because they pass through identically across all the BSP options.

Platform	Platform cost for 25 clients/month	Agency retail (₹2,999 × 25)	Gross margin per month	Margin %	Verdict
SleekFlow Premium AI (3 agency seats reseller + 25 client seats at HK$199/each)	~HK$8,000 ≈ ₹86,400/month	₹74,975/month	-₹11,425/month	Negative	Won’t work
Lion CRM whitelabel (Growth tier + 25 active licenses)	~₹25,000/month all-in	₹74,975/month	+₹49,975/month	67%	Works
Respond.io Business (covers 10 users, you re-bill 25 clients into shared seats)	US$249/month ≈ ₹20,700/month	₹74,975/month	+₹54,275/month	72%	Works (no rebrand)
AiSensy Pro (1 WABA × 25 reseller numbers — each client needs own WABA)	~25 × ₹2,399 = ₹59,975/month	₹74,975/month	+₹15,000/month	20%	Marginal
Wati Growth (1 workspace × 25 client seats)	~25 × US$15 = US$375 ≈ ₹31,125/month	₹74,975/month	+₹43,850/month	58%	Works (no rebrand)
Interakt Growth (1 WABA × 25)	~25 × ₹2,499 = ₹62,475/month	₹74,975/month	+₹12,500/month	17%	Marginal
DoubleTick Pro (1 WABA × 25)	~25 × ₹1,999 = ₹49,975/month	₹74,975/month	+₹25,000/month	33%	OK
Trengo Boost (covers 10 users, shared 25 client seats)	€159/month ≈ ₹14,800/month	₹74,975/month	+₹60,175/month	80%	Works (no rebrand)

A few things jump out from this table that you don’t always see in a generic competitor comparison:

1. SleekFlow Premium AI doesn’t survive the math. Even before Meta’s conversation pass-through, the platform cost exceeds the agency’s revenue. SleekFlow is not designed for SMB resale in INR markets — that’s a feature, not a bug.
2. Per-WABA BSPs (AiSensy, Interakt) get squeezed. Because each of your 25 SMB clients needs their own WABA, the per-client cost scales linearly. Agencies that try to make AiSensy or Interakt their whitelabel layer hit a 17-20% margin ceiling that doesn’t survive churn or refunds.
3. Whitelabel + Chrome-extension architecture is the highest margin. Lion CRM at 67% margin is roughly the same gross margin as Trengo Boost at 80% — except you get to keep your brand on the product. That’s the whole point.
4. The seemingly-cheap options (Respond.io, Trengo) only win if you don’t care about the brand. They’re cheap because each platform’s pricing model is per-user (your 10 agency seats), not per-customer (your 25 SMB clients). Once you cross 50 SMB clients each needing their own login, the math reverses.

If you want to plug your own numbers in, the Lion CRM pricing page has a downloadable agency margin worksheet — paste in your client count and retail price and it calculates platform cost across all the tiers.

Whitelabel depth: who actually lets you rebrand, and who pretends

I want to spend a paragraph on what whitelabel actually means in 2026, because the word gets used to mean very different things across these eight platforms. Real whitelabel depth has six components:

1. Brand swap in the product UI — your logo, your colors, your brand name in every screen.
2. Brand swap in the URL — your own custom domain (e.g., app.youragency.com) instead of the vendor’s domain.
3. Brand swap in the extension/app — for Chrome extensions, your Web Store listing under your developer account, not the vendor’s.
4. Brand swap in invoicing and payment — your client pays you on your invoice, you pay the vendor. Vendor name doesn’t appear on your client’s books.
5. Brand swap in customer support — your support email/phone is the only thing your client sees. Vendor support is an escalation path inside your team.
6. Brand swap in policy/terms — your terms of service, your privacy policy, your refund policy, not the vendor’s.

Of the eight platforms in this comparison, only Lion CRM is shipping all six components today (1 through 5 standard, 6 with a one-time legal-template handoff during reseller onboarding). The rest are either:

• Affiliate programmes only — you earn a commission, your client sees the vendor brand. (Respond.io, AiSensy, DoubleTick, Trengo)
• Negotiated enterprise whitelabel — possible only at high-floor pricing, only for very large resellers. (Wati does this case-by-case.)
• No programme at all — referral commission via standard partner pages. (SleekFlow)
• Interakt sits in a middle zone — Razorpay co-branding is allowed, but full whitelabel isn’t.

When an agency tells me Wati has whitelabel, what they usually mean is — Wati negotiated a co-branded plan for that agency’s enterprise contract. That’s not the same product as a self-serve whitelabel programme. If you’re an SMB-tier reseller, that distinction is the difference between a viable subscription-revenue product and a referral side-hustle.

7-step migration playbook from SleekFlow to Lion CRM

This is the playbook I send agencies who’ve decided to switch. It’s optimised for moving 25 SMB clients off SleekFlow over 30 days without missing a conversation — not for a lift-and-shift in one weekend. Treat the steps as serial — each one depends on the previous.

Step 1 — Export everything from SleekFlow first. Inside SleekFlow’s settings, export the contact list, conversation history, message templates, and any chatbot flow definitions. Save the CSVs to a folder per client. This is the safety net — if migration goes sideways, you can restore.

Step 2 — Pick the right Lion CRM tier. For a 25-client agency, the Growth tier is the right starting point. Register at admin.lioncrm.com, complete payment via PayPal, Razorpay, or wire transfer. (Whitelabel payment options are listed on the pricing page.) You’ll get instant access to the reseller dashboard.

Step 3 — Fill the Branding section. This is where your whitelabel identity lives. Upload your agency’s logo, set your colors (primary, accent, button), put your support number and your website URL, and click Save. Every license you generate from now on will inherit this branding.

Step 4 — Download your branded Chrome extension. From the reseller dashboard, click Download Extension. You’ll get a .zip file containing your agency-branded build. Keep this file safe — you’ll distribute it to your SMB clients.

Step 5 — Generate licenses + add wallet balance. For each of your 25 SMB clients, generate a paid license (consumes one active-user slot at your tier’s per-user/month fee). For prospects you’re still pitching, generate 7-day free trial licenses. Add ₹25,000 wallet balance via the Wallet section to remove per-license payment friction — every new license draws from the wallet, no per-client checkout.

Step 6 — Roll out to clients in waves of 5–10. Don’t migrate all 25 in one day. Pick the 5 most active clients first — give them the branded extension, share their license key, walk them through the 5-minute install. Watch for issues over 48 hours, fix anything that breaks, then move the next 5. By Day 21 you should have all 25 on Lion CRM and the SleekFlow seats can be downgraded to free or cancelled.

Step 7 — Cancel SleekFlow + reclaim margin. Once every client is migrated and confirmed working, downgrade your SleekFlow Pro AI plan to Free (which keeps the data accessible for 90 days) or cancel outright. The recurring HK$2,000-3,000/month you were paying SleekFlow now stays in your account as gross margin. For the agency owners I’ve walked through this playbook, that’s typically ₹20,000-30,000/month of recovered margin in month one alone.

If you hit a snag mid-migration, Kuldeep (co-founder) handles agency migration questions directly at +91 74260 34448 on WhatsApp. Most agencies clear the full migration in 14-21 days; the longest I’ve seen was 45 days because the agency staggered client rollouts around their own busy season.

Start your whitelabel WhatsApp CRM SaaS

Ready to rebrand and resell? Here’s the agency reseller flow end-to-end:

Steps:

1. Go to the admin panel → admin.lioncrm.com
2. Register your agency account, then log in.
3. Choose a plan (Starter / Growth / Enterprise) and complete payment via PayPal, Razorpay, or wire transfer. You’ll be redirected to the reseller dashboard.
4. Open the Branding section → fill in your white-label details (brand name, logo, colors, support number, your website URL) → click Save.
5. Click Download Extension to get your own white-label branded build of the Chrome extension.
6. Open the Licenses section to generate licenses:
   – Paid licenses (each consumes one active-user slot at your tier’s per-user/month fee)
   – 7-day free trial licenses (give to prospects so they can test your branded extension first)
7. Overview section gives you 1 month of free license for your own personal use of the extension.
8. Add balance once in the Wallet section — removes per-license payment friction; each new license draws from the wallet.
9. Distribute your branded extension to your customers + activate licenses. You’re now selling your own whitelabel WhatsApp CRM SaaS.

That’s the full reseller motion. The same flow is documented in video form on the LotsOfCode YouTube channel if you’d rather watch.

The honest verdict: which SleekFlow alternative fits which agency profile

If you skipped to the bottom, here’s the decision-tree version:

• You want to keep selling someone else’s brand and just need cheaper INR pricing. Pick AiSensy (Indian SMBs), Interakt (if your clients use Razorpay), or DoubleTick (if mobile-first matters). Skip Lion CRM — you don’t need the whitelabel motion.
• You’re a mid-market B2C brand with 50-200 customers, real Shopify stack, and zero plan to resell. Wati or SleekFlow itself. The cost is justified by the integration depth and the AI agent layer.
• You’re an EU agency with GDPR-first clients. Trengo. Pricing is high but the compliance posture is the differentiator.
• You want subscription revenue under your own brand from your SMB clients. Lion CRM. The other six options all have an affiliate-only ceiling that caps your brand at the vendor’s.
• You need WhatsApp Cloud API for a regulated client (bank, insurance, regulated healthcare). Wati, AiSensy, Interakt, Respond.io, or stay with SleekFlow. Lion CRM is a Chrome-extension architecture, not a BSP — it’s the wrong tool for the regulated-template-message workload.

I’ve watched all five of these decisions play out with real agency owners over the last twelve months. The ones who pick the wrong tool typically pick on cost alone (cheap BSP without the whitelabel motion they actually needed) and re-migrate within 6-9 months. The ones who pick on the brand-ownership question first don’t usually re-migrate.

Frequently asked questions

Does SleekFlow have a whitelabel programme that I missed?

No — at the time of writing, SleekFlow’s published programme is the SleekFlow Partner Programme, which is affiliate/referral only. Personalised referral links, marketing resources, and commission payouts on referred customers. That’s not whitelabel; you cannot rebrand SleekFlow as your agency’s product. If SleekFlow ships a self-serve whitelabel programme later, this answer changes — but as of 2026 the answer is no.

Is Lion CRM cheaper than SleekFlow at scale?

For a Vikram-profile 25-client agency, yes — substantially. The 25-customer math in the table above shows Lion CRM at +₹49,975/month gross margin versus SleekFlow Premium AI at -₹11,425/month (negative). Lion CRM gets cheaper because it skips Meta’s per-conversation BSP fees (Chrome extension on WhatsApp Web) and because the whitelabel reseller tier is structurally priced for resale, not for direct B2C. The only scenario where SleekFlow wins on absolute cost is a single B2C brand with very few agents and very low conversation volume.

Can I run Lion CRM alongside SleekFlow during migration?

Yes, and I recommend it. Run both for 14-30 days while you move clients in waves. Lion CRM uses WhatsApp Web in the user’s browser; SleekFlow uses the WhatsApp Business Cloud API. They can co-exist on the same WhatsApp business account for the migration window without breaking either one. Just don’t send the same template message from both simultaneously — that’s a duplicate-message risk worth avoiding.

What about WhatsApp Cloud API templates? Does Lion CRM support them?

Lion CRM is architecturally a Chrome extension on WhatsApp Web — your client’s own number sends and receives. Template messages with Meta-approved delivery receipts (the Cloud API workflow) are NOT part of the Lion CRM stack because there’s no BSP in the loop. If your specific workflow requires Meta-approved templates (e.g., a regulated bank confirmation message that must be a templated utility conversation), you need a BSP like Wati, AiSensy, or Interakt. For the 80% of SMB use cases that just need bulk sending, follow-up sequences, kanban-board pipeline, auto-reply, and contact management — Lion CRM covers all of it without the BSP layer.

How does WhatsApp Cloud API per-conversation pricing affect this math?

Meta charges per-conversation on the WhatsApp Business Platform. Marketing conversations cost roughly ₹0.78-₹2.05 in India depending on category, utility conversations roughly ₹0.10-₹0.30, and authentication conversations roughly ₹0.10-₹0.15 (numbers at time of writing — Meta updates these periodically). Every BSP-based platform (SleekFlow, Wati, AiSensy, Interakt, Respond.io, DoubleTick, Trengo) passes these through on top of the subscription cost. Lion CRM, because it doesn’t use the Cloud API, doesn’t have this pass-through layer at all — your client’s own number sends as a normal WhatsApp Web session.

Can I switch back to SleekFlow if Lion CRM doesn’t work?

Yes — the contact and conversation exports you saved in Step 1 of the migration playbook are your safety net. You can re-import them into SleekFlow’s contacts within 90 days of cancelling without losing history. I’ve never seen an agency actually do this migration, but the option is there if you need it.

What’s the minimum agency size where whitelabel makes sense?

I’d say 10 paying SMB clients is the floor. Below that, you’re better off as an affiliate on AiSensy or Respond.io because the whitelabel reseller tier fee doesn’t amortise across enough revenue. Above 10 clients, the whitelabel math works almost immediately — and above 25 clients, switching from any affiliate stack to Lion CRM whitelabel typically recovers ₹15,000-25,000/month of margin in the first three months.
