Usage-based billing means counting events at scale and turning them into money. A single mis-count or duplicate erodes the customer's trust and the close. 01 - Double counts ### One retried event, two charges When a meter event is sent twice or a sync retries, naive pipelines push two usage records to Stripe. The customer disputes the overcharge and finance issues credits all month. IDEMPOTENCY 02 - Lossy meters ### Dropped events become unbilled revenue If the app emits a usage event while the billing system is down and there's no replay, that consumption never bills. Revenue leaks quietly and nobody reconciles it back. RELIABILITY 03 - GL mismatch ### Stripe and the books tell different stories Usage posts to Stripe but the journal entry to NetSuite lags or maps to the wrong account. Finance closes the month with Stripe and the GL disagreeing on metered revenue. SCHEMA PLATFORM ## Six products. One Platform. Replace many legacy vendors.

The four concerns every billing and finance team raises before metering revenue in real time. [Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### How do you stop a usage event from billing twice? Every sync is idempotent, keyed on the source event ID. A retried or replayed meter event updates the existing usage record in Stripe instead of adding a second charge. ### What happens if Stripe is down when an event fires? Stacksync queues and retries with backoff, and every event is replayable. Usage that fires during an outage bills the moment Stripe is back, in order, with nothing dropped. ### Does usage post to the general ledger too? Yes. The same metered events flow to NetSuite or QuickBooks against the right revenue account, so Stripe and the GL agree at close instead of needing a manual tie-out. ### Can we map our own meter and rate fields? Yes. Custom usage tables, rate plans, and Stripe metadata map in the visual mapper alongside standard fields and sync the same way. ## Stop reversing duplicate charges. Bill metered usage exactly once. [Book a demo](https://www.stacksync.com/book-a-demo) [Get started](https://app.stacksync.com/)
