Why teams connect DEAR Inventory and Navan

Keep Navan and DEAR Inventory 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 Receipts, Repayments, Fees, and Adjustments, Users, Card Transactions in Navan with Stock adjustments and transfers, Assemblies / Production, Locations, Products in DEAR Inventory 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 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 02 Sync Users and department mappings from an HRIS into reporting tables so every transaction is attributed to a cost center and manager.
  • 03 Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.
  • 04 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.

Common sync patterns

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 DEAR Inventory is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where Navan handles billing: invoices land in DEAR Inventory

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