ZoneBilling
Add ZoneBilling to your product for your customers, and give your AI agents governed access to it.
ZoneBilling is Zone & Co's billing application, and the thing to understand before integrating is where it lives: a certified SuiteApp running inside NetSuite, storing its subscriptions, billing schedules, usage records and amendments as records in the customer's own account, and feeding revenue schedules into NetSuite's advanced revenue management for ASC 606 and IFRS 15. That has a practical consequence worth stating on the page. There is no separate ZoneBilling login, host or key to authorise, because the credentials are the customer's NetSuite credentials and the records are reached exactly the way any other record in that account is reached. It also means these reads and writes count against the same account-wide concurrency governance as everything else touching that instance, so a heavy usage load competes with the customer's other integrations rather than getting a lane of its own. Because ZoneBilling is configured per business, the fields on those records vary, so mapping is read from their account rather than assumed.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect the NetSuite account their ZoneBilling licence runs in, since there is no separate service to sign in to.
Push usage your product measured onto the right billing record, so a metered charge is rated from what actually happened.
Read subscriptions, billing schedules and amendments so a customer can see what they are committed to and when it bills, without opening NetSuite.
Throttle on purpose, because these calls share the account-wide NetSuite concurrency budget with every other integration that customer runs.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent says what a contract bills next month and which schedule the amount comes from.
An agent reports which contracts renew this quarter and which carry an amendment nobody has billed yet.
An agent writes an approved usage correction within scoped permissions, with the record it touched logged.
Example prompt
What does this contract bill next month, and has last month's usage been rated against it yet?
Set up ZoneBilling in 4 steps
- 01Enable the ZoneBilling connector in your fastn dashboard.
- 02Have each customer authorise the NetSuite account it runs inside, since ZoneBilling is licensed as a SuiteApp there rather than as a separate service.
- 03Map the subscription, usage and billing schedule records the way that customer has them configured, and set your concurrency budget.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the ZoneBilling integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a ZoneBilling integration without building it. Your customers connect their own ZoneBilling account inside your product and work their orders, payments and customers there, with no per-customer code on your side.
- Handle the part that actually costs time: money and order state must never be double-applied, and reconciliation has to be possible. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a ZoneBilling update is not your on-call problem.
- One integration serves your product and your agents. The same governed ZoneBilling connection powers in-product features and gives AI agents scoped, audited access, so you keep commerce and payment records in step with your product without wiring it twice.

QuickBooksZoneBilling integration FAQ
How do I add a ZoneBilling integration to my product?
Enable the ZoneBilling connector in your fastn dashboard, then let each customer authenticate their own ZoneBilling account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no ZoneBilling client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own ZoneBilling account?
Yes. Every connection is scoped to the individual customer, so each authorises their own ZoneBilling account and only ever sees their own orders, payments and customers. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this ZoneBilling integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent says what a contract bills next month and which schedule the amount comes from.
Who maintains the ZoneBilling integration?
fastn does. When ZoneBilling changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Is the ZoneBilling integration safe for payment and order writes?
Writes are idempotent, so a retry cannot double-charge or duplicate an order, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it.
Can my product react to a new order, payment or refund immediately?
Yes, through event triggers, so fulfilment, entitlement or accounting steps run as soon as the event lands rather than on a nightly sync.
What can I build with the ZoneBilling integration?
A common starting point: let each customer connect the NetSuite account their ZoneBilling licence runs in, since there is no separate service to sign in to. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the ZoneBilling integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding ZoneBilling does not change your per-connector cost. You can start free with 3 connected accounts.
