Your bookslive on WhatsApp.
Send a voice note, a text, or just type /resumen. Cuenta Clara extracts the transaction, confirms it in WhatsApp, and sends the daily P&L at 8pm for micro-businesses in LATAM.
Try these in WhatsApp
A normal day at a taqueria: messy Spanish in, clean accounting out.
The problem
Small shops sell all day, then reconstruct the books from memory.
Barbers, taquerias, and corner stores already run the business from WhatsApp. Cuenta Clara turns the habit they have into a ledger they can trust: sales, expenses, supplies, and margin.
The agent loop
Voice or text becomes a confirmed transaction.
Kapso transcribes WhatsApp voice notes, Claude Sonnet 4.6 extracts a typed object, Zod validates it, and Cuenta Clara replies with an interactive card: delete or view summary.
What the demo proves
Three inputs, two cards, one daily close.
The working flow handles voice notes, text, and /resumen. It dedupes redelivered messages, stores confirmed transactions, and sends the 8pm P&L summary through Vercel Cron.
