Why teams connect ConnectWise and QuickBooks

Connect the financial records in QuickBooks with the work happening in ConnectWise, so both stay current without exports or copy-paste.

QuickBooks holds the financial truth: who the customers are, what they were billed, what they paid. ConnectWise is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Vendors, Items, Accounts, Journal entries in QuickBooks and Contacts, Service Tickets, Opportunities, Agreements in ConnectWise in sync, bi-directionally and in real time. Whatever records ConnectWise keeps and whatever events it produces, the overlap with QuickBooks is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

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.
  • Sync time entries to payroll or BI tools for utilization analysis across technicians.
  • Sync ConnectWise companies and contacts with a CRM so sales and service teams work from the same account list.

Where ConnectWise tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Where ConnectWise handles customer conversations: billing context in view

Front-line teams see invoice and payment status from QuickBooks next to the customer they are helping, without logging into the finance system.

Where ConnectWise collects payments or triggers charges: events land in QuickBooks

Payment and charge activity flows into QuickBooks as it happens, so the books reflect reality without manual reconciliation.
