Why teams connect ConnectWise and Linnworks
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between ConnectWise and Linnworks.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Activities, Companies, Contacts, Service Tickets in ConnectWise with Stock Levels, Locations, Purchase Orders, Suppliers in Linnworks 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
- Mirror service tickets into a data warehouse or operations database for SLA and workload reporting.
- Push closed-won opportunities from the CRM into ConnectWise to kick off agreements and onboarding projects.
- Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
- Mirror processed orders, refunds, and returns into a warehouse for margin reporting across channels
