About this Product

Automatic Sales Tax & Invoicing for WooCommerce (Global) is a build-to-order plugin that ECOSIRE writes, installs and supports directly on your WordPress site. It is not an instant WordPress.org or WooCommerce.com download — after you order, our engineers tailor the plugin to your tax footprint, gateways and theme, then deploy it for you.

At its core, the plugin hooks into WooCommerce's tax pipeline (woocommerce_product_get_tax_class, woocommerce_calculated_total, woocommerce_cart_totals) to replace static tax tables with real-time, destination-based rate lookups by jurisdiction. It handles US sales-tax nexus and economic thresholds (per-state registration flags so you only charge where you're obligated), and EU/UK/AU VAT and GST on a destination basis with VAT-number validation hooks.

On the document side, a custom post type stores every invoice and credit note. The plugin generates compliant PDF invoices automatically on woocommerce_order_status_completed, attaches them to WooCommerce emails, and exposes them in the My Account area and the order admin. Credit notes are issued on refund events. A WP-Cron job batches nightly tax-summary exports for your accountant.

It is built HPOS-aware (works with WooCommerce's high-performance custom order tables, with a legacy-posts fallback), respects WPML/multisite where you run multiple storefronts, and exposes a small WooCommerce REST API surface plus WordPress actions and filters so your team can extend rate logic or invoice templates without forking core.

We configure your wp-admin settings screen, wire in your tax-data provider, validate live orders, and hand over documentation. You own the code. Tax rates change and law changes — we are honest that no plugin removes the need for a registered accountant in each jurisdiction; this automates the calculation and paperwork, not your filing obligations.

What you get

A custom WooCommerce plugin packaged for your site, installed and activated by ECOSIRE on your WordPress/WooCommerce environment

Configured tax-jurisdiction rules covering the specific countries and US states where you have nexus or registration

Branded PDF invoice and credit-note templates wired into your WooCommerce emails and My Account area

wp-admin settings configuration plus integration with your chosen tax-rate data source

HPOS / custom-order-table compatibility verification on your live WooCommerce version

Documentation covering settings, hooks/filters, invoice numbering and the WP-Cron export jobs

A staging-then-production deployment with live order validation and post-launch support window

Who this is for

Multi-region store owner

Sells into the US, EU and UK and is tired of WooCommerce's static tax tables drifting out of date. Wants accurate destination-based tax charged only where there's a nexus or registration, without babysitting rate updates.

Finance / accounting lead

Needs every order to produce a compliant, sequentially numbered PDF invoice and proper credit notes on refunds, plus a clean nightly export to hand to the bookkeeper — instead of manually reconciling WooCommerce orders.

B2B and wholesale merchant

Handles VAT-exempt and reverse-charge business customers and needs role-based and VAT-number-based tax exemption applied automatically at checkout, with the exemption reflected correctly on the invoice.

Frequently Asked Questions about Automatic Sales Tax & Invoicing for WooCommerce (Global)

How long does delivery take, since this isn't an instant download?

This is build-to-order. After we scope your tax footprint (which countries and US states, your gateways, theme and WooCommerce version), a typical build, install and live validation runs about 2 to 4 weeks. Simpler single-region setups land sooner; complex multi-jurisdiction or WPML/multisite stores take longer. We confirm a firm timeline before any work starts, deploy first to staging, then to production.

What ongoing support and updates are included?

The one-time build price includes a post-launch support window (typically 30 days) for bug fixes and adjustments. Because tax law and WooCommerce/WordPress core both change, we offer an optional ongoing maintenance plan for core-version compatibility (including HPOS changes), rate-source updates and new jurisdictions. You own the plugin code either way, so you are never locked in.

Does this remove my need for an accountant or tax registration?

No, and we won't pretend otherwise. The plugin automates rate calculation, exemption handling and invoice/credit-note generation. It does not register you for sales tax or VAT, file returns, or replace professional advice. You still need to be registered in each jurisdiction where you have an obligation; we automate the calculation and paperwork around that.

Will it work with my existing theme, gateways and WooCommerce setup?

Yes. We build against your live WooCommerce version and verify HPOS (high-performance custom order tables) compatibility with a legacy post-table fallback. The plugin hooks into the standard WooCommerce tax pipeline and email system, so it is gateway-agnostic — Stripe, PayPal and others are unaffected because tax and invoicing sit at the order layer, not the payment layer.

Where do the live tax rates come from, and what happens if a rate changes?

We integrate a real-time tax-rate data source you choose during scoping, queried by destination jurisdiction at checkout, with sensible caching to keep checkout fast. When a rate changes at the source, your store picks it up automatically. We also expose WordPress filters so your developers can override or supplement specific rates without editing core plugin code.

Can it handle VAT-exempt B2B customers and reverse charge?

Yes. Exemptions can be driven by WooCommerce user roles, by a validated business VAT number, or by destination rules for reverse charge. When an order qualifies, tax is removed at checkout and the exemption is reflected on the generated PDF invoice, including the customer's VAT number where required.
