Compare the top accounting tools for freelancers, digital nomads, and self-employed professionals living and working in Portugal.
2026 Guide • Updated July 2026Portugal's tax system requires freelancers and self-employed professionals to issue AT-certified invoices (faturas certificadas), manage VAT submissions, track Social Security contributions, and file annual IRS tax returns. Doing all of this manually is time-consuming and error-prone. The right accounting software can save you dozens of hours per year and help you stay compliant with Portuguese tax law.
If you're a digital nomad on the D8 Digital Nomad Visa or registered under the NHR 2.0 regime, you'll also need to correctly classify foreign vs. Portuguese-source income — a task that specialized Portuguese accounting tools handle automatically.

A lightweight invoicing tool popular with freelancers who issue a small volume of invoices per month. It supports AT-certified invoicing but lacks built-in VAT and Social Security management. Best suited for freelancers who only need basic invoicing.
Moloni offers AT-certified invoicing and basic accounting features. It's a solid choice for small businesses and freelancers who want a more traditional accounting interface. VAT tracking is available, but annual IRS filing requires a separate tool or accountant.
A more comprehensive accounting suite aimed at small to medium businesses. It includes invoicing, VAT, payroll, and financial reporting. It's overkill for most solo freelancers but useful if you plan to hire employees or scale your business.
Some freelancers start with custom Google Sheets or Excel templates. While free, these require manual entry, offer no AT certification, and increase the risk of errors on VAT and IRS filings. They're a reasonable option for the first few months but quickly become impractical as invoice volume grows.
