Why teams connect Navan and NetSuite

Keep Navan and NetSuite 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 Users, Card Transactions, Connect Transactions, Manual Transactions in Navan with Accounting Period, Bin Transfer, Currency Rate, Price Level in NetSuite 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 Write GL codes, cost centers, and custom-field values from an ERP such as NetSuite back onto Navan transactions through the Expense API's transaction update endpoints.
  • 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 Expose item and inventory data to internal applications through a continuously synced database table.
  • 04 Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.

Common sync patterns

Where Navan handles billing: invoices land in NetSuite

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.

What you can sync between Navan and NetSuite

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 NetSuite objects How this pairing syncs
Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Account Synced with incremental and full sync per the Stacksync docs. Manual Transactions is specific to Navan and Account to NetSuite — each maps to any object or custom field on the other side.
Bookings Flight, hotel, rail, and car reservations from the Booking API; pulled read-only by createdFrom/createdTo date range for trip and travel-spend reporting. Accounting Period Synced with incremental and full sync per the Stacksync docs. Bookings is specific to Navan and Accounting Period to NetSuite — each maps to any object or custom field on the other side.
Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Bin Transfer Synced with incremental and full sync per the Stacksync docs. Custom Fields is specific to Navan and Bin Transfer to NetSuite — each maps to any object or custom field on the other side.
Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Currency Rate Synced with incremental and full sync per the Stacksync docs. Receipts is specific to Navan and Currency Rate to NetSuite — 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. Price Level Synced with incremental and full sync per the Stacksync docs. Repayments, Fees, and Adjustments is specific to Navan and Price Level to NetSuite — 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. Term Synced with incremental and full sync per the Stacksync docs. Users is specific to Navan and Term to NetSuite — each maps to any object or custom field on the other side.

How changes propagate between Navan and NetSuite

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

NetSuite Navan Interval-based propagation

DetectionStacksync polls NetSuite for changes on an incremental schedule, reading only records changed since the previous pass. Polling on lastModifiedDate via SuiteQL or saved searches.

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.
  • NetSuite: API concurrency is governed per account; sync tools queue and throttle requests.

How the Navan and NetSuite 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.
