Features

What the connector does

Direct AdE submission

Each sale generates a FatturaPA-compliant corrispettivo sent to Agenzia delle Entrate through the OpenAPI gateway. QR code receipt returned to the customer.

Odoo POS integrated

Native POS flow unchanged: cashier closes the ticket, the receipt is submitted automatically. Multi-cash register, multi-point of sale ready.

E-commerce ready

Odoo website orders also trigger a corrispettivo for B2C sales. Same backend, same reconciliation.

Idempotent send-after-commit

Fiscal submission runs only after the Odoo transaction commits. Serialization failures no longer produce orphaned receipts or duplicates.

Refunds & voids

Return and void flows generate the matching fiscal note tied to the original receipt. Audit chain preserved.

Daily corrispettivi reporting

Totals by day / cashier / point of sale with status (sent, acked, errors) and direct links to the AdE receipt IDs.

Flow

Submission flow (idempotent, safe)

Sale closed in Odoo

Cashier closes POS ticket or e-commerce order is paid.

Transaction commits

Odoo saves the order atomically. No fiscal call happens before this.

Post-commit submission

The connector enqueues a POST to OpenAPI/AdE with an idempotency key.

AdE acknowledgement

OpenAPI returns the receipt ID and QR code. State written back into Odoo on the digital receipt record.

Why it matters: naive integrations submit to AdE inside the Odoo transaction. Under concurrent load the transaction can roll back after the fiscal call already fired — producing orphaned receipts. Our connector moves submission to post-commit callbacks, so a rolled-back sale never generates a receipt and a committed sale is sent exactly once.
