Sage Intacct
Add Sage Intacct to your product for your customers, and give your AI agents governed access to it.
A Sage Intacct integration lets your product feed the general ledger of finance teams who picked Intacct precisely because they report across entities. So the interesting part is rarely the transaction itself, it is the dimensions hanging off it: department, location, project, class, customer, vendor and whatever user-defined dimensions a company has added. Intacct also authenticates unusually, with a company id and web services credentials per customer rather than a single OAuth grant, and multi-entity companies need the correct entity context on every write or the numbers land in the wrong place. fastn stores those credentials per tenant, keeps sessions alive, and follows the XML API as it changes.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each finance team connect their own Intacct company so your product posts AR invoices and AP bills into their ledger.
Write journal entries carrying the department, location and project dimensions the customer actually reports on.
Read a company's dimension values and account list during setup so your product offers real options rather than free text.
Target the correct entity on every read and write, so multi-entity customers work without a fork in your code.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent pulls spend for one project dimension and explains which bills make up the total.
An agent drafts a journal entry for review and posts it only within the permissions it has been granted.
An agent answers where a transaction was coded by reading its dimension values, with the read logged per tenant.
Example prompt
Break down this quarter's AP spend by department and show the five largest bills in each.
Set up Sage Intacct in 4 steps
- 01Enable the Sage Intacct connector from your fastn dashboard.
- 02Have each customer authorise their own Sage Intacct account, so calls run under their credentials rather than a shared key.
- 03Decide which invoices, payments and vendors your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Sage Intacct integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Sage Intacct integration without building it. Your customers connect their own Sage Intacct account inside your product and work their invoices, payments and vendors there, with no per-customer code on your side.
- Handle the part that actually costs time: financial writes must be idempotent and reconcilable, because a duplicate is an accounting problem rather than a bug. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Sage Intacct update is not your on-call problem.
- One integration serves your product and your agents. The same governed Sage Intacct connection powers in-product features and gives AI agents scoped, audited access, so you move financial records without hand-keying them between systems without wiring it twice.

AfterShipSage Intacct integration FAQ
How do I add a Sage Intacct integration to my product?
Enable the Sage Intacct connector in your fastn dashboard, then let each customer authenticate their own Sage Intacct account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Sage Intacct client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Sage Intacct account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Sage Intacct account and only ever sees their own invoices, payments and vendors. 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 Sage Intacct 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 pulls spend for one project dimension and explains which bills make up the total.
Who maintains the Sage Intacct integration?
fastn does. When Sage Intacct 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 Sage Intacct integration safe for financial writes?
Writes are idempotent, so a retry after a timeout does not post a document twice, and every call is logged per tenant so an entry can be traced back to the event that created it. That matters more in finance than anywhere else, because a duplicate is a number somebody has to explain.
Can it handle each customer's own chart of accounts?
Yes. ERP deployments are configured to the business, so account structures, required fields and fiscal calendars differ per customer. Those are mapped per tenant as configuration, not hard-coded.
What about Sage Intacct rate limits during a first import?
Backfills are throttled deliberately. ERP limits are often account-wide rather than per-integration, so an unthrottled import can exhaust a customer's allowance and disrupt their other integrations.
What can I build with the Sage Intacct integration?
A common starting point: let each finance team connect their own Intacct company so your product posts AR invoices and AP bills into their ledger. 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 Sage Intacct integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Sage Intacct does not change your per-connector cost. You can start free with 3 connected accounts.
