Reads, never changes
No addon touches an invoice, a price or a client. Each finding links to the record in WHMCS, so you decide what to change.
WHMCS addons, built on our own installs
WHMCS will happily sell a plan for 0.00, leave an invoice open after the money arrived and keep one client on three accounts. We built these addons for our own two WHMCS installs. Each one lists what it finds, with the reason, and leaves the fix to you.
DMS.S2 — What's included
No addon touches an invoice, a price or a client. Each finding links to the record in WHMCS, so you decide what to change.
The addons call no external service. The only table each one adds holds what you dismissed, and deactivating removes it.
Dismiss what you already reviewed and it stays out of the list. A weekly e-mail goes to admins only when something new shows up.
Export the list to CSV. The screen and the e-mail come in English, Brazilian Portuguese and Spanish.

DMS.S4 — Questions
We run them on WHMCS 9.0.9 with PHP 8.3, and the test suite also passes on PHP 8.2, 8.4 and 8.5. We have not tested older WHMCS versions.
No. They only read your data. The one table each addon creates holds what you dismissed.
Payment runs in our client portal. Right after it clears, you receive an e-mail and the download is in your client area. Upload the folder to modules/addons and activate it in the WHMCS admin.
The addon keeps working. The yearly price covers new versions and support.
No. That needs each registrar's API, and the addons call no external service.
