How it works

Automatic rate selection

When you create an invoice, Descodify picks the VAT rate based on your customer's location and type. Portuguese consumer? 23%. German business with a VIES-validated VAT number? 0% reverse charge. US client? Exempt. You don't look up rules - you describe the client, we apply them.

Pre-calculated quarterly summary

Before each VAT deadline, Descodify generates a breakdown: total revenue per rate (23%, 13%, 6%, exempt, reverse charge), the net VAT you owe, and a line-by-line audit trail linking back to each invoice. You verify the numbers before entering them on the AT portal.

Recapitulative statement - the one most people miss

If you invoice businesses in other EU countries, you must also file a recapitulative statement (declaração recapitulativa) each quarter. It lists every EU B2B transaction by customer and country. AT doesn't remind you. Descodify detects EU clients in your invoices, flags the obligation, and pre-fills the statement.

Article 53 exemption tracking

If you're below the €15,000 VAT exemption threshold, Descodify tracks your cumulative revenue and warns you before you cross it. Crossing means you must start charging VAT on every future invoice - better to know before it happens.
