Why teams connect Linnworks and Slack

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Slack and Linnworks.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Slack 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Messages, Threads, Users, User groups in Slack with Suppliers, Channel Listings, Returns & Refunds, Shipping Services 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

  • Archive channel messages into a warehouse or database for compliance and analytics
  • Create or update records in a database when specific messages or reactions occur in a channel
  • Sync product and listing data with a PIM so channel listings stay aligned with the catalog
  • Push customer and order data to a CRM or marketing platform for post-purchase campaigns

Where Linnworks is the HR or people system of record

Worker and organization data from Linnworks stays current in Slack, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

Where Slack faces customers and Linnworks carries account records

Order, invoice, or account status from Linnworks appears alongside the customer in Slack, so front-line teams answer from live data.

What you can sync between Linnworks and Slack

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Linnworks objects Slack objects
Shipping Services Carrier and service definitions support label and tracking data in order syncs. User groups Handles like @support that map to teams in external systems.
Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. Files Uploads attached to messages, retrievable for archiving.
Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Reactions Emoji responses that can drive workflows, such as approving a synced record.
Stock Items SKU records keep product data aligned with ERPs and PIMs. Channels Conversations (public, private, DMs) that messages are read from and posted to.
Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods.
Locations Warehouse and fulfillment location records scope stock data during mapping. Threads Replies grouped under a parent message timestamp, preserved when archiving conversations.
