WooCommerce Invoicing
WooCommerce produces orders. An order is a record of a sale inside your shop. An invoice is a legal document — sequentially numbered, with a tax breakdown, and in a growing number of countries required in a structured electronic form. This addon issues one for every order.
What you get
- An invoice per order, issued automatically when the order reaches a status you choose (Processing and Completed by default). It mirrors the order's lines and totals exactly, including shipping and fees as visible lines.
- A payment record when the order is paid, with the gateway's transaction id.
- A credit note for every refund, for the refunded amount, referencing the invoice, carrying the refund reason.
- The Easy Invoice box on every order screen — the invoice number, Open, PDF, and (with the E-Invoicing addon) Factur-X and UBL. Orders without an invoice get an Issue invoice now button.
- An "Invoice" link in My Account → Orders for your customers.
- Backfill for orders placed before you enabled the addon.
Everything else Easy Invoice does applies to these invoices too: statements of account, VAT number checks against VIES, e-invoicing, and the rule that an issued invoice is never deleted.
Enabling
- Open Easy Invoice → Addons
- Find WooCommerce Invoicing and click Activate
- Open its settings from the sidebar to choose trigger statuses
WooCommerce must be active. High-Performance Order Storage is fully supported.
How the invoice is built
WooCommerce is the source of truth. Each product line becomes an invoice line at its post-coupon unit price; shipping and fees become their own lines. The order's VAT total is carried across, with the rate derived from the taxable base — so an order with one VAT rate reproduces WooCommerce's figures to the cent.
An order that mixes VAT rates (a standard-rated item and a reduced-rate one) is carried across at the effective blended rate. In the rare case that rounding makes the invoice total differ from the order's, the addon writes a note on the order saying so rather than letting the two quietly disagree.
The customer's billing name (or company), email and address come across, as do their billing country and VAT number — read from the meta keys the common EU-VAT checkout plugins use. That is what makes reverse charge and e-invoicing work for shop orders.
Registered customers are already Easy Invoice clients, so their invoices appear on their client record and statement. Guest orders keep the customer's details on the invoice itself.
Refunds
A WooCommerce refund issues a credit note against the order's invoice, for the refunded amount. An invoice is a tax record; a refund without a credit note leaves it saying the wrong thing. This can be switched off in the addon's settings if your accountant handles refunds another way.
What it does not do
It does not replace WooCommerce's order emails, packing slips or checkout. It does not rewrite an invoice once it exists — if you edit an invoice after it was issued, it becomes your document. And it issues exactly one invoice per order, no matter how many times the status changes or a webhook retries.
