Bulk import from your PMS

Onboard a 500-client book in an afternoon via CSV/Excel import. Skip the data-entry tax of switching deadline systems.

The Backstop is the safety net no one else offers

Duetiful is built on a four-layer safety net derived from James Reason's Swiss-cheese model. Layer 3 — the Backstop — is architecturally non-disableable by the deadline owner. Read the science, or see how other firms use it.
