ARQTA Self-billing that meets AT’s rules, from payment to invoice - automatically
Does your company pay dozens or thousands of service providers? ARQTA issues the invoices on their behalf, with ATCUD, QR code, signature chain and SAF-T, and reports everything to the Portuguese Tax Authority (AT).
Self-billing under art. 36.º do CIVA (VAT Code) · Portarias 363/2010, 195/2020 (ATCUD/QR) and 302/2016 (SAF-T)
Invoices complete for tax purposes
Numbering and series registered with AT, ATCUD, QR code and RSA signature chain on every document: invoices (FT) and credit notes (NC).
Suppliers without friction
Each service provider receives a step-by-step guide and registers the prior agreement once. The system detects the agreement and takes care of the rest.
Ongoing compliance
e-Fatura reporting, SAF-T export per supplier, VAT by region (Mainland, Azores, Madeira) and withholding tax.
Without a prior agreement too
Forestry and cork suppliers (CAE 02100 to 02400) are invoiced in your company’s own series, with no prior agreement and the VAT self-assessed by your company (art. 2.º n.º 1 m) do CIVA).
How it works
Record the payments
Import or enter the payments to your service providers, with VAT and withholding calculated automatically.
The supplier authorises once
Automatic e-mail invitation; the supplier registers the prior agreement in the Portal das Finanças in 3 minutes.
The invoices issue themselves
Series registered, invoices issued and reported to AT, with no manual steps.
Who is ARQTA for?
Companies that pay many service providers, and accountants who manage their clients’ tax compliance.
