Domain Seller

Multisite Ultimate: Domain Seller transforms your WordPress Multisite network into a powerful domain selling platform. Let customers register custom domains directly during sign-up or from their dashboard, with real-time availability checking and transparent pricing.

Why Domain Seller?​

Domain registration is one of the most requested upsells for any WaaS (Website as a Service) platform. Instead of sending your customers to a third-party registrar, you can offer domains directly — keeping more revenue in your network while giving customers a frictionless experience.

Frequently Asked Questions​

What version of Multisite Ultimate is required?​

Version 2.4.12 or higher. The addon is not compatible with WP Ultimo v1.x or Ultimate Multisite versions below 2.4.12.

Which domain providers are supported?​

Six registrars are fully supported: OpenSRS, Namecheap, GoDaddy, ResellerClub, NameSilo, and Enom. The addon's Integration Registry architecture makes it straightforward to add custom providers — see the developer guide.

Can I offer WHOIS privacy protection?​

Yes. Each domain product has a WHOIS Privacy setting with three modes: Disabled, Always Included, or Customer Choice. When set to Customer Choice, customers see a checkbox during checkout with the price (or "Free" for Namecheap's WhoisGuard). The privacy flag is automatically passed to the registrar at registration time.

Can I set different pricing for different TLDs?​

Yes. Create separate domain products for different TLD groups. Each product can have its own markup type (percentage, fixed markup, or fixed price), supported TLDs, and introductory pricing.

What checkout options do customers see?​

The Domain Selection field gives customers three tabs: Subdomain (use a free subdomain on your network), Register New Domain (search and register a new domain), and Existing Domain (map a domain they already own). Only the modes you enable will appear.

Does it support automatic renewals?​

Yes. Domains can be set to auto-renew and are tied to the customer's membership status. Renewal payments are processed through the customer's existing payment gateway.

Can customers manage their DNS records?​

Yes. Customers get a DNS management interface in their dashboard to add, edit, and delete A, AAAA, CNAME, MX, and TXT records. DNS management is available with OpenSRS, ResellerClub, and Enom.

Is there a setup wizard?​

Yes. The setup wizard runs automatically on first activation and walks you through connecting a registrar, importing TLDs, and creating your first domain product. You can also re-run the wizard from the addon settings.
