Profitable WhatsApp Commerce SaaS for Latin America: 450 Paying Merchants, 203K Accounts

This platform lets small businesses in Latin America publish a catalog or menu and take orders over WhatsApp, the channel their customers already use. Buyers browse, add to cart and pay with cash, bank transfer, card (Stripe) or PayPal. Every order is saved in the merchant's dashboard before WhatsApp opens with the order written out, so no sale gets lost in a chat. About 450 merchants pay a monthly or yearly subscription today, plus 29 whose cards Stripe is retrying, billed in 10 currencies. More than 5,300 merchants in 43 countries have paid since 2021. 203,000 accounts have been created since 2020, about 35,000 of them in the 12 months to September 2026, with TikTok (119.6K followers) as the largest source. Merchants received 10,000 to 12,000 orders a month from April to September 2026, including their own test orders; one account had 23% of orders in the 30 days to October 12. The product includes an AI page builder and editor, an AI voice agent that calls new merchants, an official WhatsApp Business API channel with approved templates, a public REST API, signed webhooks and an MCP server listed in the official MCP Registry. Agencies and multi-location businesses run many catalogs from one account, each with its own branding, payment processor and domain. The paying base is shrinking. Paying merchants went from 842 to 478 in the year to October 2026, and MRR from US$10,559 to US$8,012. Signups fell from about 7,800 a month in Q1 2025 to about 2,400 in Q3 2026, and the evidence points to recent marketing bringing in fewer new merchants as the largest cause. Monthly churn averaged 14.5% over the 12 months to September 2026, so revenue depends on steady new signups. The data room has the monthly detail.
