For portal, entitlements and usage

Stripe integration looks simple. Then the wave grows.

Wiring up Checkout takes a day. The real cost comes later: webhook sync, proration, trials, seat changes, metered billing, a billing portal… You spend months building billing infrastructure — while your product waits.

Webhook chaos

Ordering, retries, idempotency, missed events. One dropped invoice.paid means the wrong customer keeps — or loses — access.

Pricing complexity

Flat + seat + usage-based hybrid plans, currencies, trials… Keeping Stripe objects in sync by hand is a full-time job.

No portal

Where do your customers change plans? Building your own portal takes weeks; Stripe’s portal doesn’t carry your brand.

ProxyOn absorbs that wave for you: it orchestrates Stripe, keeps an authoritative local projection, and exposes it to your product through one clean API.

Go live in three steps

Your app knows the user, ProxyOn runs the billing, Stripe collects the money. The signal never stops flowing.

Your App SaaS / App ProxyOn Billing Orchestrator Stripe Stripe orchestration REST API + pxn_ key Signed webhooks
01

Connect your Stripe

Create a project and enter your Stripe keys. The onboarding wizard sets up webhooks and a default catalog for you.

02

Define your plans

Create plans, prices, and features from the panel; ProxyOn syncs everything to Stripe. Mix flat, seat, and metered pricing.

03

Embed the API

Create a subscriber, grab a portal link, query entitlements. The rest comes back to you — via webhooks.

Every wave of billing, one platform

The full subscription lifecycle from sign-up to cancellation — your Stripe account, our orchestration.

Bring Your Own Stripe

Enter your API keys and you’re done. Money flows straight to you with no middleman; ProxyOn never touches your funds.

White-label Billing Portal

Your logo, your colors, your custom domain. Customers pick plans, add seats, and cancel — without ever seeing ProxyOn.

Entitlement API

One GET answers “can this user use this feature?”. Cacheable payloads with limits and feature decisions precomputed.

Usage-based Billing

Meter with the idempotency-protected usage API; ProxyOn streams it to Stripe Billing Meters. Overages bill to the cent.

Seat-based Pricing

Per-seat prices, multi-item subscriptions, self-service seat upgrades through the portal — proration included.

Signed Webhooks

HMAC-SHA256 signed delivery with exponential backoff retries. Subscription changed? Your app knows within seconds.

By developers, for developers

Clean REST, predictable webhooks, full OpenAPI docs. Integration is an afternoon’s work.
