Core capabilities for predictable recurring file intake.

01

Define Recurring File Exchanges

Set up each recurring exchange as a feed with its cadence, expected files, partners, and handoff path. The whole exchange is visible before anyone starts chasing the next attachment.

  • Monthly, weekly, or deadline-driven file schedules
  • Required and optional files listed up front
  • Partner access, progress, and handoff visible in one place
