Compatibility releases
Each WordPress and WooCommerce release gets tested against the plugins. Ultimate Invoice 2.2.6 is tested to WordPress 6.9.7 and fully compatible with HPOS order storage.

If a free tool of mine saved you time, you can help keep it maintained.
Ultimate Invoice runs on 5,000+ WooCommerce stores and costs them nothing. It is published by Pepro Dev; I lead its development and maintenance. The same goes for the other plugins on WordPress.org and the tools on GitHub. The work that keeps them useful happens after launch day, and this page is where you can help pay for it.
Nothing is locked behind a donation. The plugins stay free either way, and a star or a review helps too.
// what-it-pays-for
What your support pays for
Time, mostly. A free plugin keeps costing hours long after it ships, and these are the hours.
Security fixes
When a vulnerability is reported, the fix ships before the disclosure deadline. CVE-2025-54869 in Ultimate Invoice was handled that way, through Patchstack.
Support and documentation
Answers in the WordPress.org forums and on GitHub, and documentation kept current with each release, including Ultimate Invoice's 190+ filter hooks.

Other ways to help
Most of what keeps an open-source project alive costs nothing. These take a few minutes and make a real difference to what I work on next.
-
Star a repository
Stars are how other developers find a project on GitHub. Pick one you have used.
-
Review a plugin
A short, honest review on WordPress.org helps store owners decide, and tells me what to fix.
-
Report a bug
Post in the plugin's support forum or open a GitHub issue, with the steps that reproduce it.
-
Translate a plugin
Add strings in your language on translate.wordpress.org, so the next store gets it out of the box.
