Set up the WHMCS cron job and automation settings
Add the WHMCS system cron, configure invoice generation, payment reminders, suspension and termination, and check Automation Status so billing runs on its own.
Set up the WHMCS order form and shopping cart
Choose and configure WHMCS order form templates, direct order links, domain options at checkout, required fields and checkout settings to improve conversion.
Single sign-on from WHMCS to cPanel, webmail and other panels
Let clients open cPanel, webmail, Plesk or Virtualizor from the WHMCS client area without passwords, configure the required API permissions and fix SSO failures.
Start selling hosting with WHMCS on a reseller or master reseller plan
A practical roadmap for launching a hosting brand: choose a reseller or master reseller plan, install WHMCS, connect WHM, create packages and products, take payments and support clients.
Stop fraudulent orders in WHMCS with fraud protection settings
Enable MaxMind or FraudLabs Pro in WHMCS, set risk score thresholds, require order approval, use CAPTCHA and order rules to block card testing and fake signups.
Troubleshoot WHMCS with System Health and logs
Use WHMCS System Health, the Activity, Module, Gateway, Email and Ticket Import logs, and safe debug settings to find out why something in WHMCS is not working.
Update or upgrade WHMCS safely (automatic and manual)
Back up, check compatibility and update WHMCS with the automatic updater or a manual upload, then verify modules, themes and the cron, and recover from a failed upgrade.
Use WHMCS announcements, knowledgebase and downloads
Publish news with WHMCS announcements, build a knowledgebase with categories and tags, offer file downloads to clients, and decide when to use an external help centre instead.
What is WHMCS? Billing and automation for hosting resellers explained

WHMCS security hardening checklist
Secure WHMCS: rename the admin folder, move sensitive folders out of the web root, lock configuration.php, enforce 2FA, restrict admin IPs, enable CAPTCHA and keep WHMCS updated.
