Why teams connect Acumatica and ConnectWise
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between ConnectWise and Acumatica.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. ConnectWise is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.
Stacksync syncs Contacts, Service Tickets, Opportunities, Agreements in ConnectWise with Vendors, Sales Orders, Invoices, Purchase Orders in Acumatica bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.
Common use cases
- Keep configuration (asset) records aligned with an external CMDB or RMM tool.
- Sync time entries to payroll or BI tools for utilization analysis across technicians.
- Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.
- Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
