Why teams connect Acumatica and Navan

Keep Navan and Acumatica 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 Repayments, Fees, and Adjustments, Users, Card Transactions, Connect Transactions in Navan with Vendors, Sales Orders, Invoices, Purchase Orders in Acumatica 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 Users and department mappings from an HRIS into reporting tables so every transaction is attributed to a cost center and manager.
  • 02 Sync Card Transactions and Manual Transactions into Postgres or a warehouse so finance analyzes corporate spend in SQL without manual CSV exports.
  • 03 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.
  • 04 Mirror stock items and quantities to external channels so availability stays accurate across systems.

Common sync patterns

Subsidiary to headquarters

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

Where Navan handles billing: invoices land in Acumatica

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.

Acumatica Navan Sub-second propagation

DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.

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

Navan Acumatica 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 Acumatica 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.
