Two-way sync
Changes in QuickBooks or Unleashed Software instantly reflect in both systems. No stale data, no manual imports.
Keep QuickBooks and Unleashed Software in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Customers, Invoices, Payments, Bills in QuickBooks with Stock On Hand, Sales Orders, Purchase Orders, Customers in Unleashed Software 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.
Invoices and payment activity from the billing side post through to the enterprise system automatically.
When one system is replacing the other, run both in parallel with records matching until the switch is complete.
Where both systems keep records of the same organizations, corrections made in either propagate to the other.
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.
| QuickBooks objects | Unleashed Software objects | |
|---|---|---|
| Estimates Quotes that convert to invoices, synced with CRM quoting flows | Stock On Hand Quantity and value per product per warehouse; the read source for availability syncs. | |
| Purchase orders Procurement documents synced with inventory and ordering systems | Sales Orders Outbound orders with lines, status, and fulfillment detail; a common write target from storefronts and CRMs. | |
| Credit memos Adjustments to receivables, needed for accurate revenue syncs | Purchase Orders Inbound supply orders synced for procurement visibility. | |
| Customers Billing entities kept consistent with CRM accounts and subscription tools | Customers Buyer records with pricing tiers and delivery addresses. | |
| Invoices Receivables created from closed deals or orders and read back for payment status | Suppliers Vendor records referenced on purchase orders. | |
| Payments Received funds applied to invoices, synced for revenue reconciliation | Warehouses Stock locations that scope inventory quantities and order fulfillment. |

Common patterns for QuickBooks and Unleashed Software: Where QuickBooks handles billing: invoices land in Unleashed Software; Migration without a hard cutover; One customer and vendor master. Invoices and payment activity from the billing side post through to the enterprise system automatically.
QuickBooks: REST API (QuickBooks Online). Authentication: OAuth 2.0. Unleashed Software: REST API. Authentication: API ID plus API key, with each request signed using an HMAC-SHA256 of the query string. Stacksync manages authentication, retries, and rate limits on both sides.
QuickBooks: Updates must include the record's current SyncToken; stale tokens are rejected, giving built-in optimistic concurrency control. Unleashed Software: Inventory quantities are tracked per warehouse, so stock syncs are warehouse-scoped rather than a single global figure. Stacksync's field mapping accounts for these differences between QuickBooks and Unleashed Software without custom code.
