Why teams connect Affinity and Linnworks

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

Affinity 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 Organizations, Opportunities, Field Values, Notes in Affinity with Returns & Refunds, Shipping Services, Open Orders, Processed 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

  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • 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

Where Linnworks is the finance system of record: money status on the account

Invoice and payment state from Linnworks shows on the account in Affinity, so reps see balances before promising the next order.

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where Linnworks manages people and org data: keep Affinity aligned

Owners, territories, and org structure informed by Linnworks stay current in Affinity.
