Recibos.do is a SaaS for small businesses, professionals and accounting firms in the Dominican Republic. Instead of typing receipts into Excel at the end of the month, anyone on the team sends a photo or PDF of the receipt to a WhatsApp number. The receipt shows up in a web panel the same day, where the team or the accountant reviews and approves it. Approved receipts export to the Formato 606, CSV or QuickBooks Desktop. DevLunch designed and built the product with Ruby on Rails and Hotwire, and it went live in May 2026.
THE ESSENCE
From the Drawer to the 606
Most receipts end up crumpled in a drawer until the accountant asks for them. Recibos turns each one into a clean line in the panel the day it arrives, and closing the month takes minutes. Send receipts from the drawer, watch them land in the panel, and approve the month.

Several businesses, one WhatsApp
People who handle more than one business choose which account each photo belongs to, right from the chat.
QuickBooks Desktop connector
Approved receipts reach QuickBooks Desktop with vendor, account and ITBIS in place, with no files to download and import.
Split receipts
One purchase that mixes expenses, like fuel and spare parts, splits into lines with their own account while staying one receipt in the 606.
Card billing in pesos
Accounts activate with a card payment, and the monthly invoice is charged automatically.
SEO from day one
