How can I edit a customer invoice

[WHMCS John]

Hi all,

Thanks very much for your feedback on the invoice immutability and credit/debit notes implementation in v9.0.

We heard you loud and clear, and I'm pleased to say that in v9.1 we have implemented an admin-configurable Invoice Immutability setting. You can enforce invoice immutability, relax it while keeping billing notes, or turn it off entirely.

For more information check out our release highlights, try it out yourselves, and share your feedback in the v9.1 Beta Discussion Board
