See why ambitious, growing B2C brands around the world choose SleekFlow

Every official provider gives you the same WhatsApp Business API, so the difference is what happens after a message arrives. SleekFlow suits B2C companies running several customer-facing teams on high WhatsApp volume, who want AI agents selling and supporting alongside people. Respond.io suits teams that want voice AI and 24/7 support on every plan. Wati suits WhatsApp-first teams working to a small budget. Omnichat suits retail brands across Asia. If a light WhatsApp inbox is all you need, a lighter platform will serve you better.

SleekFlow, Respond.io, Wati and Omnichat are all official BSPs and Meta Business Partners, so each one can apply for your WhatsApp Business API account, submit message templates and handle official business account verification. BSP status is where every serious platform starts. The differences show up after that, in migration, AI, what each one counts when it bills you, and what they publish on security.

Yes. The number stays yours, and your quality rating, approved templates, display name, messaging limits and official business account status (the green tick) move with it. Meta's migration step takes about 10 to 15 minutes, with 5 to 10 minutes of downtime. Chat history and templates that were never approved don't come with you.

Before you start, check you have full access to your Meta Business Portfolio, that your business is verified, and that two-step verification is switched off on the number. If you're still inside a contract elsewhere, you can set up on a second number and run both in parallel until it ends. The full migration checklist is in our Help Center.

Three different things get called an integration: a native connection to your CRM, a link through Zapier or Make that your team maintains, and an AI agent that can read and write live data in that system. SleekFlow connects natively to HubSpot, Salesforce, Zoho CRM, Shopify and Google Sheets, and its AI agents act on live order and customer records. Respond.io's Shopify connection is a chat widget, with order syncing through Make, n8n or Zapier.

A chatbot fires a set reply when a customer types a keyword. That holds up until someone phrases a question the way people actually phrase questions. An AI agent reads intent and works from your own knowledge base, product catalogue and live order data, so it can recommend a product, build a cart and generate a payment link. When a question gets complicated, it hands over to a person with the conversation already loaded.

Two separate meters. Meta charges per message, and since July 2025 that applies whoever you buy through, so those fees land the same way on every provider. Your platform charges its own subscription on top, and what it counts differs: some count the contacts you store, some count seats, some count the contacts you actually talk to, and some meter AI use separately in credits. That second meter is where the real difference between platforms sits.

You're charged on the contacts you actually engage with in a month. Contacts sitting in your database cost nothing, and people who receive a broadcast and never reply don't count either. Each paid plan includes a set number of user accounts and a monthly active contact allowance, topped up in small increments if you go over rather than cutting you off. Pricing varies by market, so the current list in your currency is on the pricing page.

The API itself is Meta's, so the security question is really about the platform you run it through. The certifications that matter are SOC 2 Type II and ISO/IEC 27001, plus ISO/IEC 42001 if AI agents will touch customer records. Where the data is hosted matters too, and so does what a provider's terms allow it to do with your content. SleekFlow holds all three certifications, operates in line with GDPR, and offers data residency in Hong Kong, Singapore, the US, Europe and the UAE. Reports are available on request through our Trust Center.
