OotaOS for restaurants in Kolkata.

Restaurant software for Kolkata: GST tax invoices under your GSTIN, bills you can edit after the kitchen fires, and refunds against the original payment.

Bills a Kolkata institution can stand behind

Kolkata's great restaurants are institutions, and institutions keep books. OotaOS issues sequentially numbered GST tax invoices under your own GSTIN and prefix, and when the table adds a dish after the kitchen has fired — as a long Kolkata lunch will — the bill is edited in place and its tax worked out again.

When something must go back, refunds are requested, approved and executed against the original payment, so the ledger and the gateway always agree about what was returned and why.

The dining room runs on the same system: QR ordering from the table, a live kitchen display, and a rating with a PDF receipt from the same order at the end — the modern copy of the counterfoil, for the diner and for the books.
