Overview
Pay Invoice Without Login for WHMCS is a lightweight, secure module that enables invoice payments without requiring client login. This is ideal for businesses who want to speed up the payment process by eliminating unnecessary barriers—especially when working with third-party payers, quick settlements, or non-technical clients.
How It Works
The module enables WHMCS admins and clients to generate secure, shareable links to individual invoice payment pages. These links can be sent via email, messaging platforms, or embedded in payment reminders.
There are two ways to generate and share the link:
1. From the Admin Area
-
Admins can generate a secure pay-now link for any invoice.
-
This link grants full access to the client’s account, including:
-
Invoices and billing
-
Services and domains
-
Support tickets and client profile
-
-
It behaves as if the recipient is fully authenticated as the client.
⚠️ Security Notice: These links should only be shared with trusted parties. Treat them as temporary client login tokens.
2. From the Client Area
-
Clients can generate and share a link to a specific invoice.
-
The recipient will only be able to view and pay that specific invoice, without accessing any other part of the account.
✅ Use Case: Perfect for clients who want someone else (e.g. an assistant or payer) to pay an invoice without giving full access to their account.
