Why teams connect Customer.io and Sage 300
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Customer.io and Sage 300.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Objects, Events, Segments, Campaigns in Customer.io with Purchase Orders, Inventory Items, AR Invoices and Receipts, AR Customers in Sage 300 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 account-level objects and their person relationships for B2B messaging keyed to company attributes.
- Sync product usage and billing attributes from Postgres onto Customer.io people so lifecycle campaigns trigger on real product behavior.
- Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
- Keep inventory items and quantities aligned with e-commerce and warehouse systems on a schedule.
Where Sage 300 is the HR or people system of record
Worker and organization data from Sage 300 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.
Where Customer.io faces customers and Sage 300 carries account records
Order, invoice, or account status from Sage 300 appears alongside the customer in Customer.io, so front-line teams answer from live data.
What you can sync between Customer.io and Sage 300
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.
| Customer.io objects | Sage 300 objects | |
|---|---|---|
| Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. | AP Vendors Payables vendor master synced with procurement and payment systems. | |
| Campaigns Automated workflows whose membership and metrics can be read via the App API. | GL Accounts Chart of accounts read for transaction mapping across integrations. | |
| Broadcasts One-off sends to segments or audiences, triggerable via API. | Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Order Entry Orders Sales orders written from e-commerce or EDI feeds. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Purchase Orders Procurement documents read for spend visibility and receiving. | |
| People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | Inventory Items Item master with costing and quantities, synced to storefronts and WMS. |

FAQ
Customer.io and Sage 300 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Sage 300: authenticate both systems, choose the objects to sync (such as Customer.io's Segments and Campaigns), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Customer.io: REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages. Authentication: Basic auth with site ID and API key for the Track API; bearer token for the App API. Sage 300: Sage 300 Web API (REST) on newer releases; .NET/COM SDK and direct SQL Server access on-prem. Authentication: Sage 300 user credentials (Basic auth on the Web API); database credentials for direct SQL reads. Stacksync manages authentication, retries, and rate limits on both sides.
-
Customer.io: The Track API is ingestion-oriented: integrations identify people and send events, and Customer.io matches records on identifiers such as id or email. Sage 300: Sage 300 (formerly Accpac) stores each company's data in its own SQL Server database with module-prefixed tables, so direct SQL reads are a common integration path on-prem. Stacksync's field mapping accounts for these differences between Customer.io and Sage 300 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 300 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Customer.io and Sage 300 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Customer.io–Sage 300 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Customer.io and Sage 300. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
