Why teams connect Customer.io and Infor M3

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Customer.io and Infor M3.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Customer.io 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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Campaigns, Broadcasts, Deliveries / Messages, Newsletters in Customer.io with Items, Customers, Suppliers, Customer Orders in Infor M3 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

  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • 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

Where Customer.io collects payments: transactions post through

Payment events sync into Infor M3 as they occur, keeping the enterprise records current without manual entry.

Where Infor M3 is the HR or people system of record

Worker and organization data from Infor M3 stays current in Customer.io, 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.

What you can sync between Customer.io and Infor M3

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.

Broadcasts One-off sends to segments or audiences, triggerable via API. Purchase Orders PO headers and lines sync outward so buyers and receiving teams see the same demand.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Manufacturing Orders Production order status feeds portals and CRMs so promised dates reflect the shop floor.
