この製品について
The Global VAT/GST Tax Compliance Platform is a Shopify app ECOSIRE builds to order for your store — not an instant App Store download. After you purchase, our engineers configure, install and connect it to your specific jurisdictions, registrations and accounting stack, then hand it over with documentation and support.
Cross-border selling means living with VAT in the EU and UK, GST in Australia, India, Canada, New Zealand and Singapore, and US sales tax — each with its own rates, rounding rules, invoice formats and filing calendars. Native Shopify Tax covers common cases but leaves gaps around B2B reverse-charge, VAT ID validation, multi-currency rounding and registration-threshold tracking. This platform closes those gaps.
It hooks into the Shopify Admin GraphQL API and subscribes to orders/create, orders/updated and refunds/create webhooks to capture every taxable event. Tax determination runs against a rate engine covering 100+ countries, with VAT ID validation (VIES for the EU, equivalent checks elsewhere) to apply reverse-charge correctly for verified B2B buyers. Results are written to order metafields so your invoices, exports and downstream systems stay consistent.
Multi-currency orders are reconciled to your registration currency at the booking rate, with jurisdiction-correct rounding. A threshold monitor tracks your turnover per country against registration limits (EU OSS/IOSS, UK, US economic nexus) and alerts you before you trip a new obligation. Period reports are generated per jurisdiction in filing-ready formats, with export to CSV and your accounting platform.
Because it is built to order, the data model, jurisdictions, invoice templates and report formats are tailored to your catalog and registrations — then supported by the people who built it.

Global VAT/GST Tax Compliance Platform に関するよくある質問
How long until the app is live on my store?
Because this is built to order, it is not an instant install. After purchase we confirm your registered jurisdictions, catalog and accounting stack, then build, configure and install the app. A typical first delivery is around one working week depending on how many jurisdictions and B2B rules you need; we give you a firm timeline once scope is confirmed.
Do you keep it updated, and what support is included?
Yes. Purchase includes a post-delivery support window covering bug fixes and guidance on rate and threshold updates. Tax rules change constantly, so we offer an ongoing maintenance arrangement for rate updates, new-jurisdiction onboarding and Shopify API version upgrades. We build it and we support it — the same engineers stay with your store.
Why not just use Shopify's native tax settings?
Shopify Tax handles common rate calculation well, but cross-border sellers hit its limits around VAT ID validation, automated B2B reverse-charge, registration-threshold monitoring, multi-currency rounding to a registration currency, and filing-ready per-jurisdiction reports. This platform is built specifically to cover those gaps and integrate with your accounting workflow.
Is this a guarantee that my filings are correct?
No software is a substitute for a tax advisor, and we are honest about that. The platform automates accurate calculation, captures every taxable event, and produces filing-ready reports and a defensible audit trail — which dramatically reduces manual work and error. Your accountant or tax agent still reviews and submits the actual filings.
Will it work with my multi-currency and B2B setup?
Yes. Multi-currency orders are reconciled to your registration currency with jurisdiction-correct rounding, and B2B orders run through VAT ID validation so reverse-charge is applied only for verified business buyers. These rules are configured to your specific markets during the build, not assumed.
