Why teams connect Navan and SAP Business One

Keep Navan and SAP Business One 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 Manual Transactions, Bookings, Custom Fields, Receipts in Navan with Price Lists, Activities, Business Partners, Items in SAP Business One 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 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 02 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 03 Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.
  • 04 Mirror items, stock levels, and price lists to external channels so quotes and listings use current ERP data.

Common sync patterns

Where Navan handles billing: invoices land in SAP Business One

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 Navan and SAP Business One

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.

Navan SAP Business One 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 SAP Business One through its API, with automatic retries and rate-limit backoff.

SAP Business One Navan Interval-based propagation

DetectionStacksync polls SAP Business One for changes on an incremental schedule, reading only records changed since the previous pass. Polling on update timestamps.

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

Rate-limit considerations

  • 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.
