Best invoicing & accounting tools for EU solopreneurs (2026)

VAT, OSS and e-Residency make European invoicing its own beast. Here are the tools that actually handle it — tested with a solo workflow.

25 May 2026

Invoicing as a European solo is not the same problem as invoicing in the US. The moment you sell across a border you hit VAT, reverse-charge and — for digital goods — OSS reporting. The tools below are ranked by how little of that they make you think about.

1. Xolo — the least-headache option

If you want invoicing, bookkeeping and an actual accountant handling your Estonian/EU filings, this is the closest thing to “done for you”. Built around e-Residency, so it fits remote founders especially well.

Try Xolo

2. Wise — the money layer

Not accounting, but the multi-currency business account most EU solos end up running. Get paid in several currencies without the bank eating the spread.

Open a Wise account

3. Quaderno — VAT/OSS on autopilot

Selling digital products through Stripe or Paddle? Quaderno automates the EU VAT and OSS side so you’re not reconciling tax rates by hand at quarter’s end.

Try Quaderno
