Why teams connect Infor M3 and Navan

Keep Navan and Infor M3 agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Connect Transactions, Manual Transactions, Bookings, Custom Fields in Navan with Suppliers, Customer Orders, Purchase Orders, Manufacturing Orders in Infor M3 in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 Sync Card Transactions and Manual Transactions into Postgres or a warehouse so finance analyzes corporate spend in SQL without manual CSV exports.
  • 02 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 03 Sync M3 item master and inventory balances to commerce or CPQ systems so quotes price against live stock
  • 04 Push orders captured in a CRM into M3 as customer orders without manual re-entry

Common sync patterns

Where Navan handles billing: invoices land in Infor M3

Invoices and payment activity from the billing side post through to the enterprise system automatically.

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

How changes propagate between Infor M3 and Navan

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Infor M3 Navan Sub-second propagation

DetectionInfor M3 notifies Stacksync of record changes through webhook events. Event publishing through Infor ION (Business Object Documents), configured in ION, or scheduled polling of API endpoints.

DeliveryEach detected change is written to Navan through its API, with automatic retries and rate-limit backoff.

Navan Infor M3 Sub-second propagation

DetectionNavan notifies Stacksync of record changes through webhook events. Navan's Expense API supports webhooks for transaction and expense events.

DeliveryEach detected change is written to Infor M3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Infor M3: Subject to Infor ION API gateway throttling policies.
  • Navan: Requests are throttled with HTTP 429 and Navan recommends retrying with exponential backoff; the Expense/Public API must first be enabled per account by Navan.
