EU OSS / One-Stop-Shop VAT for Magento 2

After a short scoping call we confirm your VAT edge cases (B2B/B2C mix, exempt SKUs, currencies, store scopes) and reporting format. A typical build is delivered on a staging copy of your store within about 2 to 4 weeks, followed by production install once you've signed off. We give you a firm date in writing after scoping — this is not an instant Adobe Commerce Marketplace download; it is a module we build and install on your specific Magento environment.

Each build includes a defined post-delivery support window (agreed before we start) covering bug fixes and compatibility with Magento security patches released during that window. EU VAT rates change periodically; the cron-based rate refresh keeps the per-country table current, and we can provide a longer maintenance agreement to track legislative changes and Magento version upgrades beyond the initial window.

Yes. The module targets standard Magento 2 APIs — service contracts, plugins, observers, db_schema.xml, REST/GraphQL — that are identical across Magento Open Source and Adobe Commerce, so it installs on either. On Adobe Commerce we also account for B2B company accounts and shared-catalog scenarios during scoping if they apply to your store.

It is designed not to. The extension uses a plugin (interceptor) and observers to apply destination VAT for qualifying cross-border B2C orders rather than rewriting your tax_calculation_rate and tax_calculation_rule data, so your domestic and B2B rules keep working. If you run another tax engine such as a third-party automation service, we review the interaction during scoping and define a clear order of precedence.

It produces an OSS-ready quarterly export — net and VAT totals broken down per destination country in the format we agree (CSV or XML) — sourced directly from your orders, invoices, and credit memos. That file is built to drop into your OSS portal submission or your accountant's template. ECOSIRE builds the data export and the per-country reconciliation; we do not file the return on your behalf or act as your tax advisor.

A cron job accumulates your rolling cross-border B2C distance-sales turnover (excluding domestic sales and valid reverse-charge B2B orders) and stores it in a dedicated table. The admin shows current progress toward the EUR 10,000 EU-wide threshold and raises a notification as you approach it, so you can register for OSS and switch to destination VAT at the right time instead of discovering the crossing after the fact.
