Syspro to Unleashed Software integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Syspro and Unleashed Software: authenticate both systems, choose the objects to sync (such as Syspro's Purchase orders and Jobs (work orders)), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Syspro side: AR invoices, GL journals, Warehouses, Customers, plus custom fields where Syspro exposes them. On the Unleashed Software side: Bills of Materials, Invoices, Products, Stock On Hand. 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 Syspro and Unleashed Software: Migration in parallel; Shared master data; Split by function. When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Syspro: E.net Solutions business objects, exposed over REST and WCF interfaces in SYSPRO 8. Authentication: SYSPRO operator credentials exchanged for a session token. Unleashed Software: REST API. Authentication: API ID plus API key, with each request signed using an HMAC-SHA256 of the query string. Stacksync manages authentication, retries, and rate limits on both sides.

Syspro: External access goes through e.net business objects that apply the same validation and business logic as the SYSPRO client, so API writes cannot bypass ERP rules. Unleashed Software: Every API request must carry an HMAC-SHA256 signature of the query string generated with the account's API key, sent alongside the API ID header. Stacksync's field mapping accounts for these differences between Syspro and Unleashed Software without custom code.
