Respond.io lists four plans on its pricing page: Starter, Growth, Advanced and Enterprise. Annual billing is cheaper than monthly, users are capped per plan, and monthly active contacts (MACs) are a separate tier you select. WhatsApp message fees are not included in any plan and are billed by Meta. WhatsGrow AI figures below are limits only; see pricing in your currency on our pricing page.

Respond.io is a good product. The inbox is polished, the workflow builder is deep, and it handles WhatsApp, Instagram, Messenger, Telegram, email and web chat in one place. If you answer customers on four or five channels, that breadth is the reason to pay for it.
For a small team that only talks to customers on WhatsApp, a large part of that breadth goes unused. You still pay the per-user and per-contact structure, and the AI Agents feature sits on the Growth plan, not the cheapest one.
A fair rule: if fewer than two channels carry your leads, a WhatsApp-first tool with a pipeline built in will usually cost less and take less setup. If three or more do, respond.io earns its price.
Respond.io prices on three dials at once: the plan tier, the number of users beyond the included seats, and the monthly active contacts tier. On the published page, Starter includes 5 users, Growth and Advanced include 10, and extra users run from $12 to $24 per month each depending on plan.
Monthly active contacts are the part that surprises people. You choose a MAC tier from 1,000 upward, and the page lists overages of $12 per 100 contacts on Growth and $15 per 100 on Advanced. A good month of campaigns or a lead-gen ad burst can push you into overage even if your team size never changes.
WhatsGrow AI uses flat plans. Each plan has a stated contact limit and agent limit, so you know the ceiling before you start. The tradeoff is that you move to the next plan when you hit a limit instead of paying a small overage.
Take a five-person sales and support team with about 2,000 contacts messaging them in a month, and a wish to have an AI agent answer first-line questions.
On respond.io, five users fit inside Starter ($79/mo billed yearly, $99/mo billed monthly), but AI Agents are listed as a Growth feature, so an AI-first setup points to Growth at $159/mo billed yearly or $199/mo billed monthly, with 10 users included. The MAC tier for 2,000 contacts is selected separately and the pricing page does not lay out exactly how each tier maps to each plan, so confirm the final figure in the checkout flow before you commit.
On WhatsGrow AI, five agents and 2,000 contacts fit the Growth plan (10 agents, 25,000 contacts, AI knowledge base, payments). Starter is enough only if you stay under 3 agents and 1,000 contacts. See pricing in your currency on the pricing page, and run the 7-day free trial with no card before you decide.
In both cases add Meta message fees. Meta moved to per-message pricing on July 1, 2025, charged on delivered template messages, while replies inside the 24-hour customer service window are free.
Respond.io tracks contacts, lifecycle stages and conversation status. Check its integrations list if you want it to feed an external CRM.
WhatsGrow AI puts a Kanban pipeline, deal values, tasks and assignment in the same screen as the chat, so a sales manager sees stage and revenue without leaving the inbox. It also sends Stripe or Razorpay payment links inside the conversation and moves the deal when payment lands, and it has built-in calling through Twilio or RingCentral.
If your team already pays for a separate CRM and wants the inbox to feed it, respond.io is fine. If you are trying to avoid a second tool, the built-in pipeline is the point.
Respond.io meters AI through credits: 5,000 on Starter, 10,000 or more on Growth, 20,000 or more on Advanced, with extra credits listed at $15 per 1,000. That makes AI cost variable. A busy month costs more.
WhatsGrow AI agents answer from a knowledge base you upload, can update CRM fields, create tasks, move pipeline stages, send payment links and hand a chat to a human. Language coverage includes Hindi, Hinglish, Arabic and Urdu. Plans carry AI usage limits, so check the plan page for the allowance that matches your volume.
Neither tool replaces review. Whichever you use, read the first week of AI conversations and tighten the prompt and knowledge base before widening its scope.
Stay if you depend on multiple non-WhatsApp channels, if your enterprise contract includes SSO and unlimited seats, or if your agents are trained on its workflows and routing. Moving costs real hours, and the savings only matter if the bill is a real problem.
Consider moving if WhatsApp is 90 percent of your volume, if contact overages keep showing up on invoices, or if you are paying for a separate pipeline tool and a payment tool that a single WhatsApp CRM could replace.

respond.io wins if you run many channels (Instagram, Messenger, Telegram, email, web chat) and need its enterprise maturity. If WhatsApp is where most of your revenue happens, WhatsGrow AI puts a deal pipeline, payment links and calling in the same workspace, on flat plans with no monthly-active-contact meter.
Respond.io lists Starter at $79/mo billed yearly ($99/mo monthly), Growth at $159/mo billed yearly ($199/mo monthly) and Advanced at $279/mo billed yearly ($349/mo monthly), plus Enterprise on custom pricing. Extra users and monthly active contacts are billed on top, and Meta bills WhatsApp fees separately.
Yes. You pick a monthly active contacts tier, starting at 1,000, and the pricing page lists overage of $12 per 100 contacts on Growth and $15 per 100 on Advanced. WhatsGrow AI uses a fixed contact limit per plan instead of a monthly-active meter.
No. WhatsGrow AI is WhatsApp only, built on the official Meta WhatsApp Cloud API. If you need Instagram, Messenger or Telegram in the same inbox, respond.io is the better fit and we would rather say so up front.
Respond.io offers a 7-day trial with no credit card, which includes Growth features for 5 users and 1,000 monthly active contacts, without broadcasts. WhatsGrow AI offers a 7-day free trial with no credit card required.
You do, through Meta, on both tools. Since July 1, 2025 Meta charges per delivered template message by category and country, and, since 1 October 2026, replies inside the 24-hour customer service window are free only for the first 1,000 per business number each month. Respond.io has you top up WhatsApp credit in its platform, while WhatsGrow AI does not bill Meta fees.
Yes. Your number moves with you, but it can be connected to one platform at a time. Disconnect it from respond.io, connect it through embedded signup in WhatsGrow AI, and resubmit templates. Plan the change for a low-traffic window.
For agencies running many client numbers, WhatsGrow AI offers separate client workspaces and white-label options on its agency setup. Respond.io also serves agencies, so compare both against your client count and how much branding control you need.
