Add users, assign plans, and track their balances directly via API calls — all from your frontend app. No backend required.

Balances & Payments Update Instantly

Every payment triggers API updates that instantly adjust user balances. Your frontend app always shows live data — no backend server needed.

Frequently Asked Questions

Everything you need to know

Which payment gateways are supported?

We currently support Stripe and LemonSqueezy with full webhook integration including signature verification.

How secure are the webhooks?

All webhooks are verified using HMAC signature verification. Your signing secret is used to validate every incoming request — spoofed or replayed requests are rejected automatically.

Can I manually adjust client balances?

Yes. You can add or subtract balance from any client at any time. Every manual operation is logged in the balance history with a timestamp and the staff member who made the change.

Is there a free plan?

Yes — the free plan supports up to 10 clients and one payment gateway with no credit card required. Upgrade to Pro for unlimited clients and both gateway integrations.

What happens if a webhook fails or is missed?

Both Stripe and LemonSqueezy automatically retry failed webhook deliveries. You can also manually trigger a balance top-up from the dashboard if needed.

How do refunds affect client balances?

Refund events from your gateway can be mapped to automatically deduct the corresponding balance. All deductions are recorded in the transaction history.

Ready to automate?

Connect your payment gateway and start crediting client balances automatically — no manual work, ever.
