Why teams connect Copper CRM and Linnworks

Close the gap between front office and back office: Copper CRM and Linnworks share customers and status in real time, in both directions.

Copper CRM holds the customer relationship; Linnworks runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Tasks, Projects, Pipelines, Custom Field Definitions in Copper CRM with Stock Items, Stock Levels, Locations, Purchase Orders in Linnworks field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • Enrich Copper records with product usage or firmographic data from an internal database to guide follow-up.
  • Mirror Copper data into Postgres so internal tools can query CRM state without extra API calls.
  • Push customer and order data to a CRM or marketing platform for post-purchase campaigns
  • Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
