Phone battery replacement 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 5,800.00 invoice against KSh 4,750.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for phone battery replacement. 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 battery job BAT-102 replaces one standard iPhone 13 battery through a trained technician after owner-authorised assessment. Output records model, existing battery symptoms, quoted part provenance and post-service charging/function checks. Runtime guarantees, cell rebuilding, swollen/damaged-battery handling by novices and lock bypass are excluded.
Charging basis to confirm: Battery replacement job. 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 |
|---|---|---|---|
| Illustrative battery assembly | 1 | KSh 3,500.00 | KSh 3,500.00 |
| Technician hours | 1.5 | KSh 600.00 | KSh 900.00 |
| Model seal | 1 | KSh 250.00 | KSh 250.00 |
| Protective consumables | 1 | KSh 100.00 | KSh 100.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 4,750.00 |
| Priced/accepted output | 1 example units |
| Assumed selling price | KSh 5,800.00 |
| Assumed invoice | KSh 5,800.00 |
| Difference before excluded costs and tax | KSh 1,050.00 |
Fictional cost is 3,500+900+250+100=4,750. An assumed 5,800 service fee yields 1,050 pre-tax planning surplus. Actual battery grade, calibration, disposal, diagnostics, tax and additional faults need a written quote. The 3,500 part is invented; no current supplier battery price or genuine-part availability is claimed.
Check cash timing and a weaker outcome
TRAINING-0602: a fictional order for the scoped offer in section 01, using 1 priced units at KSh 5,800.00 each. Buyer group: Owners reporting poor battery performance rather than customers seeking a promised runtime. No buyer was contacted and no order was completed.
Teaching invoice = 1 x KSh 5,800.00 = KSh 5,800.00. The selected input lines in section 06 total KSh 4,750.00; their difference from this assumed invoice is KSh 1,050.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,740.00. The invoice balance is KSh 4,060.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 3,010.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 5,800.00. Cash against the selected example bill is KSh 1,050.00 before other payments. If a hypothetical 10% increase in the largest selected line (Illustrative battery assembly) adds KSh 350.00, the unchanged invoice leaves KSh 700.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 580.00 is a receivable. Cash collected is KSh 5,220.00 and collected cash less the selected bill is KSh 470.00. 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.
