Why teams connect Linnworks and Nutshell

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

Nutshell 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 Tags, Users, Leads, People in Nutshell with Purchase Orders, Suppliers, Channel Listings, Returns & Refunds 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

  • Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
  • Push closed-won leads to accounting software to trigger invoicing automatically.
  • Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
  • Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock

Where Linnworks handles order-to-cash: closed-won flows through

A deal won in Nutshell creates or updates the customer in Linnworks with clean data, so fulfillment and invoicing start without re-entry.

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

Invoice and payment state from Linnworks shows on the account in Nutshell, 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.
