Why teams connect QuickBooks and Sage 100

Keep QuickBooks and Sage 100 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 Journal entries, Estimates, Purchase orders, Credit memos in QuickBooks with Vendors, Inventory Items, Sales Orders, AR Invoices in Sage 100 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

  • Mirror the chart of accounts and journal entries into a warehouse for consolidated financial reporting.
  • Create QuickBooks invoices automatically from closed-won deals or e-commerce orders.
  • Publish item, pricing, and on-hand inventory to online catalogs on a schedule.
  • Replicate GL and sales history to a warehouse or Postgres database for reporting off the on-premise system.

Subsidiary to headquarters

Where QuickBooks serves a business unit and Sage 100 is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where QuickBooks handles billing: invoices land in Sage 100

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.
