Why Stacksync

Built for EDI suppliers — not enterprise legacy.

  • Pre-built mappings

    Stacksync ships native mappings for every Second Source Rx document type. No more 6-week field-mapping projects.

  • Real-time monitoring

    Every transaction shows up in the dashboard the second it lands — with retry, revert, and replay built in.

  • No vendor lock-in

    Your data lives in your ERP/WMS/database. Stacksync is the translation layer, not the system of record.

  • Days, not months

    Most Second Source Rx suppliers go live in under a week. We migrate from SPS Commerce, TrueCommerce, Cleo and IBM Sterling.
