Why teams connect Customer.io and Sage Intacct
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Customer.io and Sage Intacct.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 GL Accounts, Journal Entries, Customers, Vendors in Sage Intacct 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
- Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
- Push CRM segments and lead status into Customer.io so messaging respects sales stage.
- Keep project and department dimensions aligned with a PSA or HRIS so coding stays consistent across systems.
- Create AR invoices or Order Entry transactions from subscription and order data held in a Postgres application database.
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

FAQ
Customer.io and Sage Intacct integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Sage Intacct: authenticate both systems, choose the objects to sync (such as Customer.io's Newsletters and People), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Customer.io: Beyond people, Customer.io supports non-person objects (for example accounts) with typed relationships to people, enabling account-based messaging logic. Sage Intacct: Platform Services supports custom objects and custom fields, which appear on the same API surface as standard objects. Stacksync's field mapping accounts for these differences between Customer.io and Sage Intacct without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Customer.io and Sage Intacct records are not retained after a sync operation.
