Why teams connect Navan and SAP

Keep Navan and SAP 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 Cost Centers, Business Partners, Materials (Products), Sales Orders in SAP 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 Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
  • 04 Keep MES and WMS systems aligned with production orders and goods movements.

Common sync patterns

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.

Subsidiary to headquarters

Where Navan serves a business unit and SAP is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

What you can sync between Navan and SAP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Navan objects SAP objects How this pairing syncs
Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Receipts is specific to Navan and Inventory / Stock to SAP — each maps to any object or custom field on the other side.
Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Cost Centers Controlling masters read for mapping costs in finance integrations. Repayments, Fees, and Adjustments is specific to Navan and Cost Centers to SAP — each maps to any object or custom field on the other side.
Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. Users is specific to Navan and Business Partners to SAP — each maps to any object or custom field on the other side.
Card Transactions Navan physical and virtual card spend; read via GET, then GL codes, cost centers, and ERP sync status are written back per transaction through the transaction update endpoint. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Card Transactions is specific to Navan and Materials (Products) to SAP — each maps to any object or custom field on the other side.
Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Sales Orders Order documents written from external channels and read for status and fulfillment. Connect Transactions is specific to Navan and Sales Orders to SAP — each maps to any object or custom field on the other side.
Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Purchase Orders Procurement documents synced with supplier portals and spend tools. Manual Transactions is specific to Navan and Purchase Orders to SAP — each maps to any object or custom field on the other side.

How changes propagate between Navan and SAP

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 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 through its API, with automatic retries and rate-limit backoff.

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.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.

How the Navan and SAP connectors work

Navan

Integration surface
REST (Expense API and Booking API)
Authentication
OAuth 2.0 client-credentials flow; an admin creates a client_id and client_secret under Settings > Integrations and exchanges them at Navan's OAuth token endpoint for a short-lived bearer token that is refreshed on expiry (separate US and EU regional hosts)
Change detection
Navan's Expense API supports webhooks for transaction and expense events; sync engines also poll GET endpoints with date-range and updatedAt filters (createdFrom/createdTo for bookings) to backfill history and reconcile. There is no database-level CDC.
