Affinity to Sage 300 integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Affinity and Sage 300: authenticate both systems, choose the objects to sync (such as Affinity's Persons and Organizations), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Affinity side: Opportunities, Field Values, Notes, Interactions, plus custom fields where Affinity exposes them. On the Sage 300 side: AP Vendors, GL Accounts, Journal Batches, Order Entry Orders. Stacksync auto-detects both schemas and converts types between the two systems.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Affinity and Sage 300: Where Sage 300 handles order-to-cash: closed-won flows through; Where Sage 300 is the finance system of record: money status on the account; One customer master. A deal won in Affinity creates or updates the customer in Sage 300 with clean data, so fulfillment and invoicing start without re-entry.

Affinity: REST API. Authentication: API key. 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.

Affinity: Custom fields can be global or scoped to a single list, which affects how field mappings are defined per pipeline. Sage 300: Financial transactions flow through batches that must be posted, so writes typically create batch entries rather than posted documents directly. Stacksync's field mapping accounts for these differences between Affinity and Sage 300 without custom code.
