WHMCS 9.0 introduces a new Nexus cart experience, AI Domain Namespinning, CSV support for ImportAssist, and credit and debit notes.

Updating to WHMCS 9.0 #

To take advantage of these changes, you need to update to WHMCS 9.0.

Right now, WHMCS 9.0 is a Release Candidate (RC). We only recommend RC releases for feedback, testing, and development purposes. This gives you plenty of time to make sure your customizations are up-to-date for the new version and check the compatibility of any third-party modules you use.

Nexus Cart Experience #

We have added a new shopping cart with improved UI for your clients. The new Nexus cart is dynamic, so clients can see changes without refreshing the page. This makes it easier for your clients to view new items in their cart, add promo codes, and recalculate taxes without leaving the page.

AI Domain Namespinning #

WHMCS Namespinning now includes AI-powered domain name suggestions. When clients purchase a domain, they can use a keyword or description to search for the best domain name. Clients can also still search for an exact domain name.

CSV Support for ImportAssist #

We have added support for CSV files with ImportAssist. You can use CSV files to simplify how you import customer data into WHMCS.

Credit and Debit Notes #

We have introduced credit and debit notes to our invoicing system. This feature can help you with invoice management and tax compliance by making sure all invoices list transactions consistently.

The system automatically creates credit and debit notes when you add a credit to an invoice or issue a refund. The system adds each credit or debit note to its associated invoice.

New Ledger #

The Transactions section of an invoice is now called the Ledger. The Ledger is where you will see all the transactions associated with an invoice, including credit and debit notes.
