The Four Minute Window

Scheduling software built for per-diem workforces.

Invite contractors to events, track responses, and keep all communication attached to the job — not buried in email threads. Tentative holds stay tentative until you confirm them.

Invite workflow

Accept, tentative, or decline — tracked per contractor per event.

Tentative holds

Speculative work can't block a contractor's calendar until confirmed.

Event-linked messages

All correspondence stays attached to the event, not scattered in inboxes.

Built around real scheduling friction.

The Four Minute Window keeps the surface area small and the outcomes unambiguous. Contractors can accept a tentative event — and it stays tentative until confirmed.

Invite workflow

Accept / tentative / decline tracked per event.

Tentative holds

Protect calendars from speculative “soft holds.”

Event-linked messages

Communication stays attached to the job, not lost in threads.

Multi-company ready

Contractors can operate across multiple company environments cleanly.

Contractors are always free. Companies are billed on active contractor seats above the included free seats. "Unlimited" means more than 1,000 events — Wehr Technologies reserves the right to define reasonable use.

Security-minded by design.

Role-based access

Company admins and schedulers see what they should—nothing more.

Audit-ready history

Invites, responses, messages, and all changes are tied to events for clarity.

Built for discretion

Contractors can't see each other's schedules and companies can't see each other's contractors.

Industry-standard compliance

Leverages Google Cloud Platform for data storage, processing, and authentication.

Walled gardens

Companies can have multiple environments, each with their own contractors divided by skills and experience.

No data sharing

The Four Minute Window generates revenue from company use and satisfaction, not from data sharing.
