Does the module replace my accountant?

No. It produces the OSS and IOSS reporting data and files from your real orders, but filing the returns and the final validation remain your responsibility or that of your accountant.

How is the €10,000 threshold calculated?

The module adds up your cross-border intra-EU B2C distance sales, VAT excluded, for the current and the previous calendar year. Domestic sales, B2B reverse-charge sales and exports outside the EU are excluded, in line with the EU rule.

What happens with a refund or a credit slip?

Every credit slip generates negative lines in the report. If the credit slip relates to an order declared in an earlier quarter, it is automatically isolated as a correction and shown in a dedicated section of the report and the exports.

Is there anything to do after installation?

Yes: run the historical rebuild once from the Data tab. The module then scans all your existing orders and credit slips to build the OSS and IOSS lines. Also remember to set your Member State of identification in the settings.

Does the IOSS number appear on invoices?

No. The module can add an IOSS mention on PDF invoices, but it never prints the IOSS number: that number must only be transmitted electronically to your carriers and customs representatives.

VAT OSS / IOSS — EU returns & €10,000 threshold

The OSS / IOSS VAT compliance of your EU distance sales, without a spreadsheet.

Since the 2021 EU e-commerce VAT reform, every cross-border distance sale within the EU falls under the OSS scheme as soon as your turnover exceeds €10,000 per year. This module captures every order, calculates the VAT due by country of consumption, monitors the threshold and produces your quarterly OSS and monthly IOSS returns ready to submit.

The long version

Everything you'd want to know before you install.

A detailed look at how VAT OSS / IOSS — EU returns & €10,000 threshold works, why we built it the way we did, and the thinking behind the features above.

§ 01

Who is this module for?

For any PrestaShop merchant selling goods to consumers across several EU countries. As soon as your cross-border distance sales exceed €10,000 per year, you must charge the VAT of the country of consumption and declare through the OSS one-stop shop. This module gives you the exact figure at all times, the table by country and the files to submit, without any manual rebuild in a spreadsheet.

§ 02

The €10,000 threshold in real time

The module totals your cross-border B2C sales excluding VAT for the current and the previous calendar year, as the rule requires. A gauge shows your position, the status goes from green to amber to red, and an e-mail alert is sent automatically when you reach the percentage you defined. You anticipate your OSS registration instead of being caught mid-quarter.

§ 03

Returns ready to submit

For each quarter, you export the OSS breakdown by country and by rate in CSV or XML. Credit slips issued for orders from an earlier quarter appear in a separate corrections section, in line with the OSS return format. For IOSS, a monthly report lists consignments up to €150 and isolates those that exceed this threshold.

§ 04

Installation and historical recovery

After installation, a single button scans all your valid orders and existing credit slips to rebuild the reporting lines. You immediately have the full history, including for quarters that have already elapsed. No external dependency is required and the module follows native PrestaShop conventions.
