Because this is built to order for your specific catalog, shipping zones, and target countries, typical delivery is about one working week from the time we confirm scope and get access to a staging environment. Simpler single-region setups land faster; complex multi-jurisdiction stores with ERP sync take longer. We give you a firm timeline before you pay, install on staging first, then move to production once you have signed off.

Every build includes a post-launch support window covering bug fixes and compatibility updates for new WooCommerce and WordPress releases (including HPOS changes). Tax rules change — when VIES endpoints shift, a member-state rate updates, or India's GST rules move, we update your plugin. After the included window you can extend support on a retainer. Because we built it, the same engineers maintain it; there is no anonymous third-party plugin author to chase.

No. This is a custom engagement: ECOSIRE develops the plugin for your store, installs it, configures the jurisdictions, and supports it. You are not buying a generic ZIP off a marketplace — you are getting tax logic engineered against your real catalog and a team accountable for it working.

Yes. It is built for High-Performance Order Storage (custom order tables) and writes tax data through the WooCommerce CRUD layer, so it coexists with HPOS rather than relying on legacy post meta. It also respects your existing tax classes, shipping zones, and works alongside WPML and multisite. We test it against your actual theme, gateways, and key plugins on staging before going live.

Yes. For EU buyers it validates VAT numbers against the official VIES service (with results cached via WordPress transients to stay fast and within rate limits), and for GCC it performs TRN lookups. When a cross-border EU B2B number validates, the order is zero-rated under reverse-charge and the invoice carries the legally required reverse-charge note automatically.

That is the point of the build. Invoices are sequentially numbered and include your TRN/VAT registration number, place of supply, and a line-level tax breakdown in the format each jurisdiction expects. WP-Cron generates per-country liability reports you can export for your filing periods. We configure the invoice template to your registration details during setup — though final filing responsibility always rests with you and your accountant.
