Illustration with sample dataIllustration: a PDF invoice from a fictional home goods shop, Juniper & Oak. It shows the shop's logo and address, invoice number INV-2026-0142 dated September 24, 2026 for order 1042, the billing and shipping addresses, three items (a linen table runner, two sets of stoneware mugs and a large beeswax candle) with their SKU, quantity and total, then the subtotal, shipping, VAT at 21% and the total of €131.50, paid by card. A note beside it says the PDF was attached to the Completed order email.

How it works

From the order to the accountant

Pick a design once. After that, every order gets its documents, every customer can download them, and every period can be exported.

The screens below are illustrations of the product with sample data.

  1. Step 1: Six documents from every order

    Invoices, packing slips, credit notes, proforma invoices, receipts and delivery notes, each with its own title, file name and number sequence. Packing slips and delivery notes leave the prices out and show the shipping address, weights and the customer’s note. Every WooCommerce refund gets its credit note, with the number of the invoice it corrects.

    Illustration with sample dataThe WooCommerce order screen for order 1042, completed, paid by card, €131.50. Its Documents box lists the invoice INV-2026-0142 (emailed September 24), the packing slip (printed), the receipt RCPT-1042 (emailed September 25), and the proforma invoice, credit note and delivery note, which are created when an order is on hold, with each refund and on request.
  2. Step 2: Design it while you watch

    Pick one of four designs, add your logo, colors and font, and choose what the document shows: addresses, payment and shipping method, notes, gift messages, your own custom fields, your tax ID and bank details. Drag the columns into order, rename the totals, and see every change on a real recent order, right next to the settings.

    Illustration with sample dataThe customizer in WordPress: on the left, four design thumbnails with Modern chosen, a green accent color, the Inter font, and the columns Product, SKU, Quantity and Total in drag order. On the right, the live preview of order 1042 from Juniper & Oak in the Modern design: a green header band with the shop's name and the invoice number, the addresses, three items and the total of €131.50, with a Download a test PDF button.
  3. Step 3: Created and sent on their own

    Choose the order statuses that create each document and the WooCommerce emails that carry it: the invoice when an order is processing, the proforma for a bank transfer on hold, the credit note with the refund. Numbers are given once, without gaps or duplicates, even when orders arrive at the same moment.

    The automation settings as a table: when an order is Processing, an invoice and a packing slip are created and the invoice goes with the Processing order email; On hold creates a proforma invoice for the Order on hold email; Completed creates a receipt for the Completed order email; Refunded creates a credit note for the Refunded order email. A note says numbers are given once, with no gaps and no duplicates.
  4. Step 4: Customers help themselves

    Customers download their own invoices and receipts from My Account, on the order list and the order page. Guests get a signed link that expires, in their email. Nobody sees another customer’s documents, and your team works from the order screen and the order list: create, print, regenerate or download in bulk.

    Illustration with sample dataThe shop's My Account page, on the Orders tab: order 1042 from September 24, completed, €131.50, with Invoice and Receipt downloads; order 1031, refunded, €34.00, with Invoice and Credit note; order 1018, completed, €58.00, with its Invoice. A note says guests get a signed download link that expires.
  5. Step 5: Everything your accountant asks for

    Export the documents of any period and order status as one ZIP file or one merged PDF, and the invoice summary as a spreadsheet or a PDF: number, date, customer, net, tax per rate and total. Large exports run in the background, and you are told when the file is ready.

    Illustration with sample dataThe bulk export: documents from September 1 to 30, 2026, for completed and refunded orders, invoices and credit notes, as one ZIP file. Beside it, the invoice summary with three rows: two invoices and a credit note, each with its net amount, tax and total.
  6. Step 6: E-invoices next to the PDF

    Create the UBL 2.1 file (EN 16931, Peppol BIS Billing 3.0) of each invoice and credit note, and attach it to the same emails. The customizer checks the seller details an e-invoice needs, like your VAT ID and address, and tells you what is missing before anything is sent.

    An e-invoice next to the PDF: the start of the UBL 2.1 file of invoice INV-2026-0142 with its Peppol BIS Billing 3.0 profile and euro currency. Beside it, the seller details check: business name, VAT ID and address are filled in, and a buyer reference for public bodies is optional.

Questions, answered

Straight answers about how PlugMatrix Invoices works.

Works with the rest of PlugMatrix: Live Chat, Forms, Reviews, Bookings and SEO

Does it work on Shopify, Wix or other websites?

No. PlugMatrix Invoices is made for WordPress + WooCommerce: it creates its documents from WooCommerce orders inside your WordPress site, so it needs both. Our other products work on any website; this one does not.

Do my orders leave my website?

No. The PDFs are built by the PlugMatrix plugin inside WordPress, and numbers and dates are kept with each order. PlugMatrix only learns how many documents were created each month and your last invoice number, to show them in your dashboard.

What happens to my invoices if I stop paying?

Every document already created stays downloadable, for you and for your customers. Without a plan, new documents are no longer created until you turn it on again.

Can I keep my current invoice numbers?

Yes. Set the prefix, suffix and padding you use today, and set the next number to continue your sequence. Numbers can reset every year, and a number never changes once it is given unless you regenerate the document yourself.

Can it print gift messages and custom fields?

Yes. Ask for an optional gift message at checkout (or read it from your gift plugin) and print it on packing slips, delivery notes or any other document. Add up to ten custom fields, such as a PO number or a delivery date, from the order or the customer’s account, each on the documents you choose.

Does it work with High-Performance Order Storage?

Yes. It uses the WooCommerce order API only, so it works with High-Performance Order Storage and with the classic order tables.

Which e-invoice formats does it create?

UBL 2.1 invoices and credit notes with the EN 16931 core fields, in the Peppol BIS Billing 3.0 profile, from the Growth plan. It creates the file and attaches it to your emails; sending it through the Peppol network is done by your access point or your accountant.

Does it handle other languages and currencies?

Amounts use the order’s currency and your WooCommerce price format, right-to-left languages are laid out right to left, and documents use the order’s language where WordPress switches it. Support for WPML, Polylang and TranslatePress is coming next.

Is it legally compliant?

It prints what an invoice usually needs, such as sequential numbers, dates, your tax ID, company number and tax per rate, once you fill them in. Rules differ by country, so check with your accountant which details yours needs; we do not give tax advice.

Which plugin version do I need?

Version 1.14 or later of the PlugMatrix WordPress plugin, and WooCommerce. The dashboard tells you when a site needs an update.

Invoices your customers can trust

Turn it on for your WooCommerce store, pick a design, and the next order has its invoice.
