Desktop assembly 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 50,000.00 invoice against KSh 45,300.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for desktop assembly 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 desktop build PC-109 targets 16GB RAM,512GB SSD and integrated graphics for office documents. One approved bill of materials names actual CPU, motherboard, RAM, storage, case and power supply before purchase; no unspecified socket compatibility is assumed. A competent assembler follows component manuals. Output is serial/BOM record, diagnostics and owner handover; mains-power-supply repair and pirated software are excluded.
Charging basis to confirm: Completed desktop build. 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 |
|---|---|---|---|
| CPU | 1 | KSh 15,000.00 | KSh 15,000.00 |
| Motherboard | 1 | KSh 12,000.00 | KSh 12,000.00 |
| 8GBRAM modules | 2 | KSh 2,500.00 | KSh 5,000.00 |
| 512GBSSD | 1 | KSh 4,500.00 | KSh 4,500.00 |
| Case | 1 | KSh 3,000.00 | KSh 3,000.00 |
| PSU | 1 | KSh 4,000.00 | KSh 4,000.00 |
| Assembler hours | 3 | KSh 600.00 | KSh 1,800.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 45,300.00 |
| Priced/accepted output | 1 example units |
| Assumed selling price | KSh 50,000.00 |
| Assumed invoice | KSh 50,000.00 |
| Difference before excluded costs and tax | KSh 4,700.00 |
Illustrative cost totals 45,300; one assumed 50,000 sale leaves 4,700 pre-tax planning surplus. All component prices are fictional pending exact compatible BOM. OS licence, peripherals, delivery, returns, tax and extended burn-in are excluded. Capacity targets are not a performance benchmark or a current Kenyan parts quote.
Check cash timing and a weaker outcome
TRAINING-0609: a fictional order for the scoped offer in section 01, using 1 priced units at KSh 50,000.00 each. Buyer group: Small offices and users needing a transparent build rather than the cheapest component list. No buyer was contacted and no order was completed.
Teaching invoice = 1 x KSh 50,000.00 = KSh 50,000.00. The selected input lines in section 06 total KSh 45,300.00; their difference from this assumed invoice is KSh 4,700.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 15,000.00. The invoice balance is KSh 35,000.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 30,300.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 50,000.00. Cash against the selected example bill is KSh 4,700.00 before other payments. If a hypothetical 10% increase in the largest selected line (CPU) adds KSh 1,500.00, the unchanged invoice leaves KSh 3,200.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 5,000.00 is a receivable. Cash collected is KSh 45,000.00 and collected cash less the selected bill is KSh -300.00. 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.
