auto_awesome What this module does
AI-generated from the code · Odoo 18.0This module makes Odoo compliant with Portuguese invoicing certification rules: it assigns official AT document series, secures posted documents with a digital signature and QR code, and adds cancellation and reprint controls.
For Portuguese companies, this module enforces the legal requirements of the Portuguese tax authority (AT) on sales invoices, receipts, credit notes and inbound payment receipts.
- You must create AT Series (with a name, document types, prefixes and AT validation codes) and link them to sales or payment journals. Each document gets an AT Series, a unique document number and an ATCUD code.
- Once a document is posted, it is digitally signed (hash) and gets a QR code. After signing, key data cannot be changed and the document cannot be reset to draft.
- The module blocks invoices without VAT, negative or zero lines, and requires an exemption reason on zero-rated taxes. Discounts are limited to 0–100% and a global discount is combined with line discounts.
- Cancelling a document requires a reason, and reprinting a document also requires a reason. Credit notes must have a reason and cannot exceed the original invoice amounts.
- It adds warnings for future-dated documents and prevents issuing earlier-dated documents in the same series after a future-dated one.
- It also adds a hash integrity report and a payment mechanism field on payment methods.
