There is no single price, and the money leaves in two directions. Meta prices the WhatsApp messages, and whoever builds the bot prices the build. At Walabi, some ready-made products start at $799 MXN a month, and a bot built around your operation is quoted separately.
In short
- Two costs: Meta's per-message fees and the builder's fee for the bot. Whether they reach you as one invoice or two depends on who holds the WhatsApp Business account.
- Since July 2025 Meta charges per template message delivered, with rates that vary by template category, volume tier, and country or region rate.
- Meta's pricing page, updated on September 10, 2026, announces pricing updates for service and utility messages on August 1 and October 1, 2026.
- At Walabi, some ready-made products start at $799 MXN a month (Mexican pesos), that entry price covers the catalogue in general rather than a WhatsApp bot specifically, and a custom build is quoted separately.
What Meta charges, whoever builds the bot
Meta prices the WhatsApp messages, separately from your builder's own charge. Meta's page shows both setups, a business integrated directly and a Solution Provider that Meta charges instead, so ask which one your account will be. According to Meta's official pricing page, updated on September 10, 2026, the model changed on July 1, 2025: it used to charge per open conversation, and now it charges per template message delivered.
The same page says rates vary by template category (marketing, utility, or authentication), volume tier, and country or region rate. It also announces that the pricing updates for service and utility messages roll out on August 1, 2026 and October 1, 2026.
From October 1, 2026 Meta also charges for each service message (which can only be sent inside an open 24-hour customer service window), at the same rates as utility and authentication per market, with a free monthly tier of 1,000 delivered service messages per business phone number that does not roll over.
Meta can move those rates up to four times a year, on the first day of each quarter. Before you sign anything, ask to see the rate card the estimate was built on, and the date it was pulled.
Does where your business is registered change what you pay?
In two ways that Meta's page spells out, though neither is the message rate itself. Rates follow the country calling code of the number receiving the message, so budget with the rate card for the markets you message. The first thing your address changes is the authentication-international rate: Meta's page says that, per their primary business location, businesses may continue to be charged the authentication rate in one of the 18 markets that have an international rate, with 30 days' notice before those charges begin.
The second is the currency your account is billed in. Meta's page says that only businesses and providers whose Sold-To country is Brazil can open new WhatsApp Business accounts in Brazilian reals, invoiced by Meta's local entity there, and that India works the same way in rupees, each with a migration deadline. If your bot sends authentication messages or your company is registered in either country, ask your builder which rate card and which currency your account falls under.
The one price on this page is in Mexican pesos. If you budget in another currency, ask in which currency the quote and the invoice will be issued, who carries the exchange rate between them, and whether a monthly fee is re-quoted when the rate moves. Ask for that in the same sentence as the price, not in a later email.
What Walabi charges
Walabi does not run one flat rate. Some ready-made products start at $799 MXN a month, and that entry price covers the catalogue in general, not a WhatsApp bot specifically. Other ready-made products can cost considerably more, depending on their size and the volume you handle.
There are two paths. A ready-made product is a bot Walabi already built and adjusts to your operation, and it can go live in days. A fully custom build is written from scratch for your case, takes 4 to 12 weeks, and is quoted separately, based on the integrations you ask for and how complex the conversation is. If nothing ready-made fits, here is more on custom software for a small business.
What pushes the price up
A bot that answers opening hours and an address is a different job from one that takes orders, charges for them, and checks stock before confirming. Four things move the number.
- Conversation complexity.Fixed answers with a linear flow cost less than natural language, several branches, or a guided purchase. Some bots run on AI, and here is what to ask about where your data lives in that case.
- Integrations.Wiring the bot into a CRM, stock records, or a payment system adds development work, and cost.
- Expected message volume.Handling hundreds of customers a day at once needs a sturdier setup than fielding the occasional question.
- Extra features.In-chat payments, custom notifications, and automatic reports add value, and budget.
If a bot is one piece of a larger cleanup, here is where to start automating a business in Mexico. And if the account is new, start by setting up automatic replies in WhatsApp Businessbefore committing to a full bot.
What to settle before you sign with a builder abroad
Distance changes which questions matter. A demo tells you the bot works; it does not tell you what happens on a Monday when something breaks and the team answering is in another time zone. Get these answered in writing, before the first invoice.
- Which hours the team actually answers in, and what happens to an urgent fix outside them.
- Which language the working sessions run in, and who on your side will attend them.
- Who owns the code, and who owns the WhatsApp Business account, if you move to another provider later.
- What the handover includes: message templates, conversation flows, and the credentials for the account.
- Whether the quote separates the build, the monthly fee, and the Meta message fees line by line.
Frequently asked questions
Can a company outside Mexico hire a builder in Mexico for this?
Yes, and two things are worth settling up front: who holds the WhatsApp Business account, and which rate card the quote used. What is specific to Walabi is that the free discovery call runs in Spanish, with people, so bring a Spanish speaker to that first conversation if you need one. Ask which currency the quote will be issued in when you ask for the price.
Who pays Meta, my company or the builder?
That is a contract question rather than a technical one. Ask the builder to put in writing who owns the WhatsApp Business account Meta bills, and whether their quote includes those message fees or leaves them out.
How soon could a bot be answering customers?
At Walabi, a ready-made product can go live in days. A fully custom build takes 4 to 12 weeks, depending on how complex what you are asking for turns out to be.
If you want to know what a WhatsApp bot built around your operation would cost, book a free 30-minute call, in Spanish and with real people: you leave with a map of what is worth buying ready-made, what is worth building custom, and what is not worth automating yet.
