In WHMCS, you can configure your domain registration and pricing settings and choose a registrar to customize how you sell domains. When you sell domains, issues with domain availability checks, registration, or renewals can cause serious problems. Problems with your system email can prevent you from sending email to clients or connecting to your mail provider. Domain statuses indicate the domain's current state in the domain registration process. WHMCS's automation uses the domain status to determine when to generate invoices and perform other tasks. The Domains tab in the Client Profile contains details and management options for all of a client's domains. Use the Auto Renew on Payment setting to configure WHMCS to automatically renew domains after the client has paid the renewal invoice. WHMCS's automation settings determine when the system cron runs, whether to perform certain tasks, and the details for running each task. Troubleshoot and resolve issues with broken domain renewal links in emails. Troubleshoot and resolve issues with domain renewal invoices that the system has set to Cancelled. Configure your domain grace and redemption fees to charge customers for renewing expired domains during the grace and redemption periods. You can manually disable renewals for an individual domain. You may want to do this if you want the domain to expire without an invoice. Your Domain Pricing configuration sets the prices for domain registrations and how to handle namespinning, premium domains, and more. The Domains tab in General Settings allows you to configure how WHMCS manages domain registrations. You can choose how WHMCS handles renewals and transfers, configure grace and redemption fees, enable IDN domains, set your default nameservers, and more. The Email Notifications registrar module lets you work manually with customers' domain registrations and management. Enable or disable client domain renewal orders. If you disable this, clients can only renew domains by paying the renewal invoice. Manually approve domain renewal with your domain registrar. You may need to manually stop automatic renewal requests for the domain. Troubleshoot and resolve issues with domain renewal invoices that aren't generating. Manually try to register or transfer a domain again after resolving an error or other failure that occurred during the last attempt. Manually try a domain-related module action again after resolving an error or other failure that appears in the Module Queue. Customize your own gace period lengths for domain names if you don't want to use the default for the domain extension (TLD).
