Selling across the whole EU (OSS)

A worked example, end to end — which settings to pick and exactly what each buyer pays.

Is this you? You're VAT-registered and your cross-border sales are growing — you've passed (or will soon pass) €10,000 a year from EU consumers outside your country. You want to sell to every EU country without worrying about the cap. The answer is one registration: OSS (One Stop Shop).

Step 1 — register for OSS (outside Onelo)

OSS is a free registration with your own country's tax authority. Once you have it, you charge each EU buyer their own country's VAT — and instead of filing in 27 countries, you file one quarterly OSS return at home that distributes the VAT for you. Onelo links to your country's registration portal right next to the checkbox.

Step 2 — turn it on in Onelo

WhereDashboard→Settings→Payments & Tax→Tax Setup→2 · Tell us about your business

Make sure “Yes — I charge VAT” is selected and your VAT number is filled in — OSS requires VAT registration (exempt sellers use the EX scheme instead).

WhereDashboard→Settings→Payments & Tax→Tax Setup→3 · Registrations→Consumers (B2C)

In the LV2 row choose “OSS — charge the buyer-country VAT”, then tick “I am registered for OSS (One Stop Shop)” in the checklist that appears (use the Register ↗ link if you haven't yet). Finish with Save changes.

The €10k cap disappears. With OSS you charge the buyer-country VAT from the very first cross-border sale — so the Thresholds section stops showing a ceiling. Onelo confirms it on the page: “No turnover cap — OSS charges the buyer-country VAT from the first cross-border sale, with no €10k/€100k ceiling.”

The “EU consumers (B2C) — over €10k/yr” row should now read “buyer rate · OSS”. Check it before saving.

Good to know

  • Invoices take care of themselves. Each invoice carries the buyer-country rate and a note that the VAT was charged via OSS — issued by whichever provider you chose in Tax & Invoicing.
  • You still file the OSS return yourself (quarterly, in your home portal). Onelo computes and collects the right VAT per country; the Transactions export gives your accountant the per-country breakdown.
  • Pricing tip: with VAT-inclusive (gross) prices, your margin varies slightly per country (different VAT inside the same price). That's normal for OSS sellers — or use net pricing for B2B-style products.
