OrderBay Lite

OrderBay Lite adds the invoicing tools a WooCommerce store legally needs — free forever, no license key, no account, no phone-home.

• PDF invoice for every order, made on your own server: a Download PDF button on the order screen, the orders list, and the customer’s My Account, plus a printable view (browser Print → Save as PDF)

• PDF invoice attached to WooCommerce emails: Completed order and Customer invoice by default; Processing order, Refunded order (credit note PDF), and the admin New order email can be ticked too

• Sequential, race-free invoice numbers with configurable prefix, format tokens ({PREFIX} {YYYY} {MM} {SEQ:5} …), and yearly/monthly counter reset

• Credit note numbers and a printable credit note for refunded orders

• Packing slips: a price-free print view with items, SKUs, quantities, variation details, ship-to address, and customer note

• Customers can download the PDF or print their own invoice from My Account (owner-only, nonce-protected)

• Factur-X / ZUGFeRD PDF invoices (PDF/A-3 with the invoice data inside), made on your own server, for download or attached to emails

• XRechnung 3.0 for German public-sector buyers, as XML or as a ZUGFeRD PDF

• E-invoice XML export: UBL 2.1 (Peppol BIS Billing 3.0) and UN/CEFACT CII (Factur-X EN 16931), with a seller-details readiness checklist. The UBL carries the seller’s and buyer’s Peppol IDs, worked out from their VAT numbers or entered by hand

• EU withdrawal button: a “Withdraw from contract here” link and page, a confirmation step, and emailed acknowledgements, as EU consumer law has required since 19 June 2026 (off until you turn it on)

• Invoice numbers are immutable once assigned and survive plugin updates

• Compatible with WooCommerce HPOS and block checkout

• Help & demo page: one-click demo order with invoice, credit note, UBL, and CII, and a support ticket form

Not tax advice: invoice layout, numbering, VAT lines, and e-invoice files are tools — confirm legal requirements with your accountant or tax adviser. Sample invoices pass the official KoSIT and Mustang validators; check one of your own orders through a validator before relying on it, and note that OrderBay Lite does not transmit anything to the Peppol network.

Bundled libraries

PDFs are made by Dompdf, bundled inside the plugin (lib/vendor/oblt-dompdf) so it works on any host with the PHP mbstring and dom extensions. Remote fetching and embedded PHP are turned off; a logo stored on your site is read from disk. Each library keeps its license file:

• Dompdf 3.1.6 — LGPL-2.1 — https://github.com/dompdf/dompdf

• php-font-lib 1.0.2 — LGPL-2.1-or-later — https://github.com/dompdf/php-font-lib

• php-svg-lib 1.0.2 — LGPL-3.0-or-later — https://github.com/dompdf/php-svg-lib

• masterminds/html5 2.9.0 — MIT — https://github.com/Masterminds/html5-php

• sabberworm/php-css-parser 8.7.0 — MIT — https://github.com/MyIntervals/PHP-CSS-Parser

• DejaVu Sans font (shipped with Dompdf) — Bitstream Vera / DejaVu license (free)

com/orderbay/. It is a different plugin. This Lite plugin is complete and is never locked.

External services

OrderBay Lite has no license check, no telemetry, no account, and makes no outbound requests during normal use. All documents are generated on your own site. The one exception is a support ticket you choose to send.

Support tickets (only when you send one): the Help & demo page has a support form. com/wp-json/tp/v1/support. Nothing is sent automatically, in the background, or on a schedule, and no passwords, keys, or customer/order data are included.

Service provider: Tillpress (Alex Software Holdings LLC). com/terms/. “Email instead” opens the same ticket in your own email app and sends nothing from the site.
