You can accept crypto payments in WHMCS by adding a cryptocurrency payment gateway plugin that connects your billing system to a crypto payment processor. Sheepy allows WHMCS merchants to offer cryptocurrency checkout for invoices, subscriptions, hosting services, VPS plans, domain payments, and other client billing flows. After the plugin is installed and configured, Sheepy becomes available as a payment method on WHMCS invoices. Customers can choose crypto, complete the payment through a hosted checkout, and the plugin helps keep invoice statuses updated inside WHMCS.
A cryptocurrency payment gateway connects WHMCS invoices with a secure crypto checkout and payment monitoring system. When a client chooses crypto as the payment method, Sheepy generates the payment flow, tracks the transaction, and sends payment updates back to WHMCS. This helps businesses manage cryptocurrency payments without manually checking every invoice. Webhook notifications allow WHMCS to receive real-time payment status updates, so invoices can move through the billing process more smoothly after the crypto transaction is detected and confirmed.
Yes. WHMCS is widely used by hosting providers, VPS platforms, domain registrars, and SaaS companies to manage invoices, renewals, and client billing. With the Sheepy WHMCS crypto payment plugin, these businesses can add cryptocurrency payments to their existing billing workflow. This is useful for hosting and VPS companies that serve international customers, crypto-native users, or clients who prefer digital asset payments. Sheepy helps connect crypto checkout with WHMCS invoices while keeping payment confirmations and billing data synchronized.
The Sheepy WHMCS crypto payment plugin is built for hosting providers, VPS platforms, SaaS businesses, domain registrars, and other companies that use WHMCS for invoices, subscriptions, renewals, and client billing. It helps these businesses accept cryptocurrency payments while keeping their billing workflow inside the existing WHMCS system. The plugin also helps synchronize invoice statuses, payment confirmations, renewal payments, and transaction data between Sheepy and WHMCS. This makes crypto payment processing easier for businesses that already rely on WHMCS to manage customer accounts and recurring billing.
Yes. Sheepy supports automatic invoice status updates in WHMCS through webhook notifications and payment synchronization. When a customer pays an invoice with cryptocurrency, Sheepy monitors the transaction and sends payment status updates back to WHMCS. This helps reduce manual billing work for merchants. Invoice records can stay connected to the payment result, making it easier to manage confirmed payments, pending transactions, and completed crypto invoices inside the existing WHMCS environment.
To configure the Sheepy plugin for WHMCS, merchants need to install and activate the module through the WHMCS admin panel. Then they should log in to the Sheepy merchant dashboard and generate the API Key, API Secret Key, and Notification Secret Key in the Integration section. These credentials allow WHMCS to connect securely with the Sheepy crypto payment gateway and receive real-time payment updates. After the credentials are created, merchants can open the Sheepy payment gateway settings in WHMCS and enter the API Key, API Secret Key, and Notification Secret Key. Once the settings are saved, Sheepy becomes available as a crypto payment option on WHMCS invoices. Customers are redirected to the hosted Sheepy checkout to complete cryptocurrency payments, while webhook notifications keep invoice statuses updated as each payment moves through the process.
No. The Sheepy WHMCS plugin is designed to work with your current WHMCS setup without major changes or custom development. Businesses can add cryptocurrency payments to WHMCS while continuing to use their existing invoice, renewal, and client billing processes. Sheepy automatically synchronizes payment confirmations, invoice statuses, and billing data with WHMCS. This allows merchants to accept crypto payments through WHMCS without rebuilding their payment flow or manually updating invoice records.
The Sheepy plugin for WHMCS can be downloaded from the Crypto payment plugins page on the Sheepy website.

It supports secure API authentication, webhook-based payment notifications, automatic invoice status updates, and hosted cryptocurrency checkout without custom gateway development.
