Delivered is not finished — and the fitter’s phone works without signal.

✓Packages sorted in reverse route order so the last stop loads last
✓Stacking that respects level, cabin height and weight per stack
✓Position, row and level written per package, with no-fit and overweight flagged
✓Proof of delivery: signature, photo, GPS and the name of whoever received it

✓A portal login and an installable app, not an ERP seat
✓The last-loaded schedule and opening grids stay readable in a dead spot
✓Ticks and photos queue on the handset and replay in order when signal returns, with an honest count of what is still waiting

✓Configurable stages — delivered, frame fixed, sealed, glazed, hardware, final check, handover
✓A stage that requires evidence cannot be closed without it
✓Piece rate per stage, if that is how your crews are paid

✓Sold, surveyed, produced, delivered, installed — and the gap between each pair
✓The stage holding the most work right now, named
✓Warranty starts itself the day the job is handed over

The numbers on the wall

The installation control tower: progress, units done, site momentum, items by state, actions by type, the quantity funnel with its leakage, and an installer leaderboard.
