A six-branch fashion chain lost every Thursday to rota juggling. We built a scheduler that drafts weekly rotas from availability, contract hours and foot traffic, then handles confirmations and shift swaps over WhatsApp. Rota building fell from five hours to twenty minutes.

The challenge
Each week, the operations manager juggled availability notes, contract-hour minimums and six branches' opening patterns in a spreadsheet — five hours of work that still produced clashes. Swap requests arrived as calls and texts at all hours, took a day to resolve, and about nine shifts a month ended up uncovered, leaving stores understaffed at peak.

−96%The automation
We built a scheduling engine that ingests staff availability, contract hours and approved leave, then layers hourly foot-traffic patterns from the POS to set staffing levels per branch. Every week it drafts a complete six-branch rota for the manager to tweak and publish. Shifts go out on WhatsApp for one-tap confirmation, and swap requests automatically find eligible colleagues, collect their acceptance, and land with the manager as a single approve button.
How it works
- 01
Collect the constraints
Staff availability, contract hours and approved leave sync into the engine ahead of every scheduling run.
- 02
Read the traffic
Hourly foot-traffic patterns from the POS set target staffing levels per branch, per shift.
- 03
Draft the rota
The engine builds a compliant six-branch rota in minutes; the manager tweaks and publishes.
- 04
Confirm on WhatsApp
Every employee receives their shifts on WhatsApp and confirms with a single tap.
- 05
Swap without phone tag
Swap requests find eligible colleagues automatically and reach the manager as a one-tap approval.

The impact
Weekly rota building dropped from five hours to twenty minutes, and the draft respects contracts and traffic patterns before a human ever looks at it. Swaps resolve in about an hour instead of a day, uncovered shifts fell from nine a month to two, and managers got their Thursdays back.
Questions about this automation
What does the rota builder take into account?
It reads each employee's availability, contracted hours and approved leave, plus hourly foot-traffic patterns from the POS for every branch. From these it sets target staffing per shift and drafts a weekly rota that meets contract minimums and avoids clashes. The manager reviews, adjusts and publishes it.
How do shift swaps work on WhatsApp?
An employee requests a swap by replying on WhatsApp. The flow finds colleagues who are available, qualified for that branch and within their contract hours, and offers them the shift. Once one accepts, the manager gets a single approve button, and the rota and both employees are updated automatically.
What is needed to start, and how is it rolled out?
The build needs staff details and contract hours, access to POS traffic data, and a WhatsApp Business API number for shift messages. It is a multi-step build, usually rolled out in stages, often with one or two branches first before the full chain moves to the automated rota.
