Bin washing service 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 5,400.00 invoice against KSh 4,020.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for bin washing service. 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: Twelve emptied household bins with separately identified lids, washed at an agreed contained station and returned to their owners. Exclude hazardous waste, sharps, chemical drums and pest treatment. The work proceeds only after an authorised wastewater route is established for the actual site.
Charging basis to confirm: bin per 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 |
|---|---|---|---|
| Two washers, three hours each | 6 | KSh 280.00 | KSh 1,680.00 |
| Compatible product used, litres | 0.3 | KSh 900.00 | KSh 270.00 |
| Wash-equipment job allocation | 1 | KSh 650.00 | KSh 650.00 |
| Collection/return transport | 1 | KSh 800.00 | KSh 800.00 |
| Containment/recovery allocation | 1 | KSh 500.00 | KSh 500.00 |
| Numbered labels | 12 | KSh 10.00 | KSh 120.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 4,020.00 |
| Priced/accepted output | 12 example units |
| Assumed selling price | KSh 450.00 |
| Assumed invoice | KSh 5,400.00 |
| Difference before excluded costs and tax | KSh 1,380.00 |
Illustrative batch cost = 6 × 280 + 0.3 × 900 + 1 × 650 + 1 × 800 + 1 × 500 + 12 × 10 = KSh 4,020.00. Cost per priced unit = KSh 335.00; revenue = 12 × KSh 450 = KSh 5,400.00; pre-tax difference = KSh 1,380.00. No environmental or sewer authorisation fee is invented. Any actual licensing, receiving-site or disposal cost must be added after authority advice. No guaranteed profit; tax, premises, finance and actual correction costs must be added where applicable.
Check cash timing and a weaker outcome
TRAINING-0360: a fictional order for the scoped offer in section 01, using 12 priced units at KSh 450.00 each. Buyer group: Households, estates and small businesses. No buyer was contacted and no order was completed.
Teaching invoice = 12 x KSh 450.00 = KSh 5,400.00. The selected input lines in section 06 total KSh 4,020.00; their difference from this assumed invoice is KSh 1,380.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,620.00. The invoice balance is KSh 3,780.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 2,400.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 5,400.00. Cash against the selected example bill is KSh 1,380.00 before other payments. If a hypothetical 10% increase in the largest selected line (Two washers, three hours each) adds KSh 168.00, the unchanged invoice leaves KSh 1,212.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 540.00 is a receivable. Cash collected is KSh 4,860.00 and collected cash less the selected bill is KSh 840.00. 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.
