Mobile Time-Clock App

Maintained Shipped April 30, 2026 Updated October 23, 2026 Zapier

Built a one-tap clock-in and clock-out app for every employee's phone that logs each punch to a shared sheet and a private Slack channel, running alongside the payroll system of record.

1tap per punch
18seats rolled out
2logs per punch: sheet + Slack

Business impact

Gave leadership a same-day view of attendance without changing payroll, with an audit trail in two places and a weekly reconciliation step.

Problem

Leadership had no real-time view of who was in and when; punches lived only in the payroll platform, which is built for payroll, not for a same-day operational picture.

Solution

Each employee gets a home-screen app with two tiles, Clock In and Clock Out, each opening a personal pre-filled form so the punch takes one tap and carries the person's identity. Two Zaps write every punch to a Clock Log sheet (with daily first-in, last-out and total hours computed) and post it to a private Slack channel. The payroll system stays the system of record; the sheet is a parallel log reconciled weekly.

Results & highlights

  • One tap per punch: identity travels in each employee's personal pre-filled link, so there is nothing to type
  • Sized for the automation plan before rollout: about 1,600 tasks a month for 18 seats, inside the plan's ceiling
  • Rolled out with a two-day single-user pilot, a 15-minute all-hands install and a same-day verification against the payroll log
  • Migrated to Google Forms on 2026-10-23 with regenerated personal links and QR codes for every employee

Competencies demonstrated

  • Workflow automation: Form-to-Zapier-to-Sheets-and-Slack pipeline with per-employee pre-filled identity.
  • Rollout management: Pilot, all-hands install and day-one verification against the system of record.
