Priority Software
Add Priority Software to your product for your customers, and give your AI agents governed access to it.
Embed a Priority Software integration so your customers can work their own ERP records from inside your product instead of hand-keying them. Priority ERP covers the general ledger, accounts receivable and payable, invoicing, purchasing and inventory, and its REST API exposes those as OData over Priority forms. Financial writes have to be idempotent and reconcilable, because a duplicate is an accounting problem rather than a bug, so retries do not post a document twice and every call is logged per tenant. Each company's account structures, required fields and fiscal calendars differ, so those are mapped per customer as configuration, and first imports are throttled deliberately.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Priority ERP company so documents created in your product post to their books.
Create invoices, journal entries or purchase orders from your product with per-tenant idempotency on every write.
Read customers, items, price lists and document status so your product works from the ERP's own data.
Map each company's own accounts, required fields and fiscal calendar during setup rather than in your code.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads an invoice and its lines before answering a question about a balance.
An agent posts a document within governed permissions, with the write idempotent and traceable to the event that created it.
An agent reacts to a posted or approved document and runs the next accounting step.
Example prompt
List unpaid customer invoices over 30 days old and total them by customer.
Set up Priority Software in 4 steps
- 01Open the Priority Software connector from your fastn dashboard.
- 02Have each customer authorise their own Priority company with least-privilege API credentials.
- 03Map the forms, accounts and document types your product reads and writes, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Priority Software integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Priority Software integration without building it. Your customers connect their own Priority Software 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 Priority Software update is not your on-call problem.
- One integration serves your product and your agents. The same governed Priority Software 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.

AfterShipPriority Software integration FAQ
How do I add a Priority Software integration to my product?
Enable the Priority Software connector in your fastn dashboard, then let each customer authenticate their own Priority Software account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Priority Software client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Priority Software account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Priority Software 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 Priority Software 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 reads an invoice and its lines before answering a question about a balance.
Who maintains the Priority Software integration?
fastn does. When Priority Software 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 Priority Software 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 Priority Software 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 Priority Software integration?
A common starting point: connect their own Priority ERP company so documents created in your product post to their books. 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 Priority Software integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Priority Software does not change your per-connector cost. You can start free with 3 connected accounts.
