Why teams connect Plex ERP and QuickBooks

Keep QuickBooks and Plex ERP 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 Items, Accounts, Journal entries, Estimates in QuickBooks with Inventory, Production jobs, Sales orders, Purchase orders in Plex ERP 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

  • Reconcile payment-processor payouts against QuickBooks transactions.
  • Sync invoices and payments between QuickBooks and the CRM so sales sees billing status on the account record.
  • Push sales orders captured in e-commerce or EDI systems into Plex for scheduling and fulfillment.
  • Mirror purchase orders and receipts to accounting or planning tools.

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 QuickBooks serves a business unit and Plex ERP is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where QuickBooks handles billing: invoices land in Plex ERP

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