About this Product
Since July 2021, an EU B2C seller crossing EUR 10,000 in annual cross-border distance sales must charge the VAT rate of the customer's destination country and remit it through a single One-Stop-Shop (OSS) quarterly return. Magento Open Source and Adobe Commerce ship a flexible but origin/manual tax engine — tax_calculation_rate and tax_calculation_rule tables driven by zip/region rules. They have no native concept of an OSS threshold, no destination-rate library, and no OSS return export. Merchants end up hand-maintaining dozens of rate rows and reconciling returns in spreadsheets.
This is a build-to-order extension. ECOSIRE designs, builds, installs, and supports it on your Magento install — it is not an instant Adobe Commerce Marketplace download. We deliver a proper module under app/code/Ecosire/EuOssVat that hooks Magento's tax subsystem the right way: a plugin (interceptor) around Magento\Tax\Model\Calculation\Rate plus an observer on tax_rate_data_fetch/sales events so destination VAT is applied at quote and invoice time without overwriting your existing rules. Rates are stored in a dedicated table, exposed through a service contract (Api/OssRateRepositoryInterface), and surfaced over REST and GraphQL for headless/PWA storefronts.
A cron job keeps the per-country rate table current and accumulates cross-border B2C turnover so the store flags when you approach EUR 10,000. An admin grid (with its own Ecosire_EuOssVat::oss ACL resource) shows tax broken down per destination country, and a one-click export produces an OSS quarterly return file your accountant or tax portal can consume.
Scope, edge cases (mixed B2B/B2C carts, VAT-exempt SKUs, marketplace deemed-supplier rules), and your exact reporting format are agreed up front. Honest delivery: a working build on a staging copy of your store, then production install and a support window — see the FAQs for lead time.
What you get
- A custom Magento 2 module (Ecosire_EuOssVat) under app/code with composer.json, registration.php, module.xml, di.xml, and acl.xml — installable via setup:upgrade
- Database schema (db_schema.xml) for the OSS rate table and turnover-accumulation table, with declarative upgrade-safe migrations
- Installation on a staging copy of your store first, then production deployment, including setup:di:compile and static content deploy verification
- Admin configuration: OSS rate grid, threshold settings, country/rate mapping, and the destination tax breakdown report wired to the ACL resource
- Cron jobs (crontab.xml) for rate refresh and threshold accumulation, plus the OSS quarterly export action
- REST and GraphQL coverage (webapi.xml / schema.graphqls) for destination VAT and OSS rate data, documented for your storefront team
- A short admin runbook: how to read the per-country breakdown, run the quarterly export, and update rates when EU rates change
- A defined post-delivery support window for bug fixes and Magento patch-compatibility (scope agreed before build)
Who this is for
Cross-border EU DTC brand owner
Sells direct-to-consumer across multiple EU countries on Magento Open Source, has crossed (or is about to cross) the EUR 10,000 distance-sales threshold, and needs destination VAT charged correctly so OSS returns are defensible rather than reconstructed from spreadsheets.
Finance / VAT compliance lead
Responsible for filing the OSS quarterly return. Wants net and VAT totals broken down per destination country directly from the store of record, with an export that maps to the tax portal or the accountant's template — not manual extraction from Magento reports.
Magento developer or agency lead
Maintains the merchant's Adobe Commerce or Open Source install and wants destination-VAT logic delivered as a clean, upgrade-safe module (plugins, service contracts, ACL, GraphQL) that survives Magento patch cycles rather than core hacks or fragile tax-rule sprawl.

Frequently Asked Questions about EU OSS / One-Stop-Shop VAT
How long does delivery take, since this is build-to-order?
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 one working week, 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.
What ongoing support and updates are included?
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.
Does this work on both Magento Open Source and Adobe Commerce?
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.
Will it conflict with my existing tax rules or another tax extension?
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.
Does it generate the actual OSS return I submit to the tax authority?
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.
How does the EUR 10,000 threshold tracking actually work?
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.
