WHMCS and Scalable Billing Operations

WHMCS is a widely used billing and automation platform for hosting providers, SaaS companies, and digital service businesses. It manages client accounts, recurring invoices, service provisioning, renewals, and lifecycle automation from a single system.

As businesses grow internationally, payment reliability becomes critical. Failed card payments, regional banking limits, and delayed settlements often lead to overdue invoices and disrupted renewals. A flexible, global payment option is essential to keep billing predictable and cash flow stable.

Accept Crypto Payments in WHMCS with OxaPay

OxaPay provides a dedicated WHMCS plugin built specifically for invoice-driven billing systems. The plugin integrates directly into WHMCS invoices, allowing clients to pay with cryptocurrency without changing existing billing or automation workflows. Payments are completed on a secure OxaPay invoice page. After confirmation, clients are automatically returned, and invoice statuses update instantly inside WHMCS. All payment behavior, supported coins, and automation settings are managed from your OxaPay Merchant panel.
