Accelerate your revenue with secure, shareable invoice links.

Pay Invoice Without Login for WHMCS is a powerful module designed to simplify the payment process by allowing invoices to be paid without requiring the client to log in. Whether you’re working with third-party payers, one-time clients, or simply want to speed up the billing cycle, this module lets you share a direct, secure link to any invoice.

Invoices can be easily shared with friends, family, accountants, or external payers — anyone who needs to make a payment on behalf of the client. When the recipient opens the link, they’re taken directly to the invoice payment page — no login required. It’s the ideal solution for reducing friction in your payment flow while keeping things secure and client-friendly

With the new v2.0 update, the module now offers enhanced security and control features such as setting an expiration time while sharing invoice links, optional PIN/password protection, QR code generation for quick access, email sharing options, link open tracking, detailed access logs with IP and time, and admin-level controls to disable the sharing feature for all clients, specific clients, or selected client groups. These additions ensure a more secure, flexible, and fully controlled invoice sharing experience.
