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 Xolo2. 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 account3. 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.

| If you are… | Start with |
|---|---|
| A service solo who hates admin | Xolo |

| Getting paid in multiple currencies | Wise (always) |
The right answer is the one you’ll actually keep using at quarter-end.
