Mobile car wash in Kenya: Pricing, Costing and Cash Flow Example
Editorial update: 28 October 2026 · Business planning reference · Review scope
Use one accepted sale unit throughout
Work through a fictional KSh 4,200.00 invoice against KSh 3,224.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for mobile car wash. The order below is an invented teaching case. It is not a completed customer job, an operating approval or a prediction of demand or earnings.
The example offer and its boundary
Fictional sample order: Two mobile saloon exterior washes at one private property, with owner-approved water access and a feasible contained wastewater route. Quote travel/setup separately from washing. Exclude public-road operation, uncontrolled runoff, engine cleaning and pressure near unassessed electrics.
Charging basis to confirm: mobile visit. The rates and quantities below are teaching assumptions. Even a previously recorded listing is not adopted here as a current quotation or an earnings forecast.
Itemised arithmetic
| Selected input/activity | Quantity | Assumed unit rate | Selected cost |
|---|---|---|---|
| Operator wash/setup hours | 4 | KSh 320.00 | KSh 1,280.00 |
| Travel time hours | 1.5 | KSh 300.00 | KSh 450.00 |
| Vehicle/fuel allocation | 1 | KSh 650.00 | KSh 650.00 |
| Shampoo use, litres | 0.12 | KSh 1,200.00 | KSh 144.00 |
| Recovery/site allocation | 1 | KSh 500.00 | KSh 500.00 |
| Towel processing | 2 | KSh 100.00 | KSh 200.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 3,224.00 |
| Priced/accepted output | 2 example units |
| Assumed selling price | KSh 2,100.00 |
| Assumed invoice | KSh 4,200.00 |
| Difference before excluded costs and tax | KSh 976.00 |
Illustrative batch cost = 4 × 320 + 1.5 × 300 + 1 × 650 + 0.12 × 1200 + 1 × 500 + 2 × 100 = KSh 3,224.00; cost per priced unit KSh 1,612.00. Revenue = 2 × KSh 2100 = KSh 4,200.00; pre-tax difference KSh 976.00. Two cars share one trip; do not model this as two separate travel revenues. Utility, recovery and travel assumptions require actual site quotes. Tax, premises, finance and actual rework must be added where applicable; no guaranteed earnings.
Check cash timing and a weaker outcome
TRAINING-0462: a fictional order for the scoped offer in section 01, using 2 priced units at KSh 2,100.00 each. Buyer group: Estate residents and office parking managers. No buyer was contacted and no order was completed.
Teaching invoice = 2 x KSh 2,100.00 = KSh 4,200.00. The selected input lines in section 06 total KSh 3,224.00; their difference from this assumed invoice is KSh 976.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,260.00. The invoice balance is KSh 2,940.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 1,964.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 4,200.00. Cash against the selected example bill is KSh 976.00 before other payments. If a hypothetical 10% increase in the largest selected line (Operator wash/setup hours) adds KSh 128.00, the unchanged invoice leaves KSh 848.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 420.00 is a receivable. Cash collected is KSh 3,780.00 and collected cash less the selected bill is KSh 556.00. This differs from invoice margin; do not spend the unpaid amount as though it is already cash.
The scenario is complete only as a teaching record of the stated lines. Add actual excluded startup and operating costs using file 12, and replace every assumed rate before relying on a quote. Use measured accepted output for the actual invoice; unaccepted output is not automatically chargeable.
For an actual quote, add all relevant excluded costs, use measured accepted output, and compare amounts from the same period. An unpaid invoice balance is not available cash. A deposit held for an uncompleted obligation is not automatically earned income.
