This is built-to-order, not an instant download. After we confirm your jurisdictions, tax classes and invoice requirements, a typical build runs about one working week depending on how many markets and edge cases (reverse-charge, IOSS, multisite) are involved. We need staging access to your WordPress/WooCommerce site, your current tax setup, and sample products. We develop on staging, run live test orders, then deploy to production.

Every build includes a defined post-launch support and update window agreed in writing before we start. During that window ECOSIRE handles bug fixes, WooCommerce/WordPress compatibility updates and adjustments when a covered jurisdiction changes its rules. You own the plugin code on your own server, so you are never locked into a subscription to keep it running. Extended support or new-market additions can be scoped as follow-on work.

The plugin automates calculation, invoicing and reporting accurately for the jurisdictions we build it for, and it flags threshold and nexus crossings. It does not replace your accountant or file returns for you. You remain responsible for registering in each market and submitting filings; the OSS/IOSS and per-region reports are designed to make that filing straightforward.

Yes. We build against High-Performance Order Storage (custom order tables) and write compliance data to order meta so it stays consistent with WooCommerce's modern storage. WPML and multisite are supported when your build requires them. During scoping we review your active plugins and gateways so the tax engine integrates cleanly with checkout and invoicing rather than conflicting with them.

Off-the-shelf tax plugins are generic and often tie you to a metered third-party rate API and recurring fees. We build a plugin tailored to your exact markets, your invoice rules and your stack, installed in your own codebase. Where a SaaS rate service genuinely helps, we can integrate one, but the logic, reporting and support stay yours and stay scoped to how you actually sell.
