OrderBay Lite

No. Every feature listed above works without a key, trial, or phone-home to the author.

The first time an invoice is printed, downloaded as a PDF, or attached to an email, the order is assigned the next sequential number. The counter increments atomically in the database, so two simultaneous prints can never receive the same number. Numbers are immutable once assigned.

Yes. Logged-in customers get “Invoice” and “Invoice PDF” buttons on My Account → Orders, and “Print invoice” and “Download PDF” on the order view page. Only the customer account that placed the order (or store staff) can open them; guest orders are not reachable from My Account.

Factur-X / ZUGFeRD PDF (EN 16931 profile, or the XRechnung profile), XRechnung 3.0 XML, UBL 2.1 (Peppol BIS Billing 3.0) and UN/CEFACT CII. The PDF is a PDF/A-3b file made by the bundled PDF engine, nothing extra to install. Export only: OrderBay Lite does not send anything to the Peppol network. Check one of your own orders through an official validator before relying on it.

Yes. OrderBay Lite bundles the Dompdf PDF engine, so the Download PDF buttons and email attachments work on any host with the PHP mbstring and dom extensions (standard on almost every host). Nothing else needs installing, and the PDF is made on your own server; nothing is sent to an outside service. The browser Print → Save as PDF view is still there.

By default the customer’s Completed order and Customer invoice / Order details emails. Under WooCommerce → OrderBay Lite → PDF invoices in emails you can turn attachments off, or also tick Processing order, Refunded order, and the admin New order email. Admin emails never get a PDF unless you tick one. The Refunded order email carries the credit note PDF, and only when the order already has a credit note number (Lite never issues one just because an email is sent). If a PDF cannot be made, the email still goes out without it and the reason is logged under WooCommerce → Status → Logs (source: orderbay-lite).

Only briefly, in wp-content/uploads/orderbay-lite-tmp/ (blocked from web access, random folder names). Each file is deleted as soon as the email is sent or fails, and an hourly clean-up removes anything older than an hour.

Open WooCommerce → OrderBay Lite help . The support form there sends your ticket straight to the Tillpress support desk at tillpress.com after you tick the consent box and press Send ticket; you get a ticket number on screen and the reply comes by email. It includes your name, email, message, this site’s address, and (optional) a system report of versions, theme, and active plugins; never passwords, keys, or customer data. Prefer email? “Email instead” opens the same ticket in your own email app. You can also use the WordPress.org support forum for this plugin or https://tillpress.com/support/. Replies Monday to Friday, 09:00 to 17:00 Pacific Time; first reply within one business day.

Yes. On WooCommerce → OrderBay Lite help , click Create demo data . It creates one completed order with a partial refund, numbered DEMO-INV-0001 and DEMO-CN-0001, so you can open the invoice, the credit note, and the UBL and CII e-invoice XML. Your real invoice and credit note counters are not touched. Everything is labelled “Demo”, never emailed, and removed with one click (or when you uninstall the plugin).

Only on its own Help & demo page: one box describing the paid OrderBay plugin with an optional 20% discount code. It can be hidden for good with “Hide this offer”. There are no dashboard-wide notices, no tracking, and no referral IDs.

Lite steps aside automatically so you do not get duplicate buttons or a second number sequence. You can deactivate Lite.
