Car wash — multi-lane express + detail bay · Nairobi, Kenya
A four-lane express wash with two detail bays replaced paper tickets and informal M-Pesa tracking with Clean Garaji. Owners gained lane-level throughput metrics and same-day revenue close.
Outcomes below reflect common patterns from Kenyan customer rollouts — representative composite scenario, not a single named client.
Cars stalled between wash, dry, and detail stages with no live queue view. Attendants collected M-Pesa without tying payments to lane tickets. Owners only knew daily totals after manual SMS matching.
