Prismaat has partnered with FIZ — certified invoicing and accounting software for freelancers and the self-employed in Portugal.
If you work as a freelancer or trabalhador independente in Portugal, you already know the paperwork never really stops: certified invoices, VAT, Social Security, IRS deductions, the e-Fatura portal. FIZ brings it all into one place — personal and business accounting together — so you can spend less time on admin and more on your work.
FIZ is AT-certified invoicing software (no. 3041), so every invoice you issue is legally valid in Portugal. And it goes well beyond invoicing: a bit of everything for your personal, contract and business accounting.

Why it matters for your move
Setting up as self-employed is one of the most common routes for people building a life in Portugal — D8 digital nomads, freelancers and small business owners. Getting your invoicing and accounting right from day one keeps you compliant with the AT and Social Security and makes tax season painless. FIZ handles that side; Prismaat helps with the rest of your move.
