Enforce usage quotas before the request — not after Stripe invoices

SDK enforceQuota(tenant, meter), Stripe sync, and a customer-facing usage bar. Hard-block or degrade when over limit — stop whales from punching through margin.

Problem

Billing is not entitlement

Meters bill usage; they do not atomically enforce entitlements. Teams reinvent Redis counters, webhook ordering, grace windows — and still eat margin leaks.

Before

Stripe invoices after traffic already blew past
DIY Redis + webhook reconciliation
Customers don’t know why they’re limited

After

Pre-request hard-block or degrade
OOTB SDK + Stripe sync
Transparent portal usage bar

Solution

What QuotaGate does

An entitlement enforcement layer for usage/hybrid AI SaaS — because invoicing is not access control.

WHO

AI SaaS founders and backend leads moving from seats to usage or hybrid pricing.

PROBLEM

Billing meters do not stop traffic; DIY atomic counters and webhook sync leak margin and create support debt.

SOLUTION

SDK enforceQuota + Stripe sync + customer usage UI with hard-block or degrade policies.

RESULT

Heavy users cannot silently pierce your unit economics between invoice cycles.

Features

Marketing points derived from the product hypothesis — for demand validation, not a formal spec promise.

⚙️

enforceQuota(tenant, meter) SDK

Atomic check and reserve / decrement on the API or edge middleware; reject or mark degrade immediately when over limit.

🔁

Stripe sync

Keep Stripe Meters / subscription state aligned so billing and entitlements don’t drift.

📊

Customer usage portal UI

A customer-facing usage bar and remaining allowance — fewer “why was I blocked?” tickets.

🧱

Over-limit policies

Hard-block, degrade, or short grace / override (configurable) — policy lives at the gate, not month-end reconciliation.

⏱️

Built for usage／hybrid AI SaaS

Entitlement on the meter dimension for seat→usage transitions — not just a feature flag.

How it works

A three-step loop matching the waitlist-stage product hypothesis.

1
Drop in the SDK
Call enforceQuota(tenant, meter) on your API path.
2
Sync with Stripe
Keep subscription/meter state aligned to reduce drift.
3
Show usage + enforce policy
Customer usage bar; hard-block or degrade when over limit.

If these situations sound familiar, join the waitlist to help us validate.

AI feature with per-token or per-run limits

Stop a single tenant from burning GPU/API budget between invoices.

Hybrid seat + usage plans

Seats unlock product; meters must still gate the expensive endpoints.

Customer success overrides

Grant temporary grace without disabling enforcement for everyone else.

Replacing fragile Redis DIY

Retire weekend-maintained counters and webhook reconcilers.

FAQ

How is this different from Stripe Meters / Entitlements?

Meters bill; we enforce quotas at request time and show customer usage UI.

How do you compare to Lago / Orb / Metronome?

They lean full billing platforms; we focus on OOTB entitlement middleware at the gate.

Do I replace Stripe?

No. Sync with Stripe; we don’t replace collections.

When is early access?

Batch email invites. No fake launch date.

Which runtimes?

Validation targets common backend SDK paths; final list in product docs.
