Why teams connect Attio and Infor M3

Close the gap between front office and back office: Attio and Infor M3 share customers and status in real time, in both directions.

Attio holds the customer relationship; Infor M3 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 Users, Deals, Workspaces, Custom objects in Attio with Price Lists, Items, Customers, Suppliers in Infor M3 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

  • Run a two-way dual-run when migrating to Attio from another CRM.
  • Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.
  • Feed manufacturing order status to a customer portal for order tracking in fashion, food, or equipment supply chains
  • Keep supplier and purchase order data aligned between M3 and procurement tools
