Stacksync features and specs

  • Two-Way Sync
    Keep your systems perfectly aligned with Stacksyncโ€™s reliable two-way data synchronization. Changes made in one platform automatically update across all connected systems in real time, eliminating data silos, reducing errors, and ensuring your teams always work with the latest information.
  • Workflow Automation
    Stop building brittle API scripts. With Stacksync, you can trigger complex automated workflows using simple SQL commands. Instantly initiate email sequences, update CRM statuses, or fire webhooks whenever a specific record changes in your database, giving you total control without the maintenance headache.
  • EDI
    Transform legacy EDI complexity into simple database interactions. Stacksync automatically parses incoming EDI documents directly into your database tables and converts outgoing data back into compliant EDI formats. Manage your supply chain with the ease of SQL, not ancient file parsers.
