Description
Hosted Stripe Checkout
Stripe Checkout Module for WHMCS
Stripe Checkout Module for WHMCS integrates Stripe Checkout hosted payment pages with your WHMCS billing system, allowing customers to pay invoices securely through Stripe.
The module supports one-time invoice payments and recurring products using Stripe Subscriptions, with webhook-based invoice updates and customer/subscription tracking inside WHMCS.
Stripe Checkout Without Local Card Handling
Customers complete payment on Stripe’s hosted checkout page instead of entering card details directly into WHMCS. This creates a cleaner payment experience while keeping invoice creation, service records, and billing automation inside WHMCS.
Core Features
- Stripe Checkout Integration: Create hosted Stripe Checkout sessions directly from WHMCS invoices.
- One-Time Payments: Process standard WHMCS invoices using Stripe Checkout payment mode.
- Stripe Subscription Support: Use Stripe subscription mode for recurring WHMCS products when enabled.
- Customer Reuse: Creates and stores Stripe customer IDs for WHMCS clients to keep future payments connected.
- Automatic Price Creation: Finds or creates Stripe products and prices based on invoice amount, currency, and billing cycle.
- Subscription Tracking: Stores Stripe subscription IDs against WHMCS services for later synchronization.
- Verified Webhooks: Validates Stripe webhook signatures using the configured webhook signing secret.
- Automatic Invoice Updates: Applies payments to WHMCS invoices when Stripe confirms successful checkout or invoice payment events.
Recurring Billing Support
When Stripe Subscriptions are enabled, the module detects the WHMCS billing cycle and creates a matching Stripe recurring price. This helps recurring WHMCS services continue through Stripe’s subscription system.
- Monthly subscriptions
- Quarterly subscriptions
- Semi-annual subscriptions
- Annual subscriptions
- Biennial subscriptions
- Triennial subscriptions
Smart Recurring Handling

- Due Date Sync Hook: Recreates Stripe subscriptions with a new billing anchor when the WHMCS service due date changes.
