Paving block installation 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 47,000.00 invoice against KSh 39,400.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for paving block installation. 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: Lay ten square metres of pedestrian paving in a small yard after competent base/drainage assessment. Customer approves block type, pattern, edges and finished levels. No vehicle loading, buried-service excavation or foundation/retaining design is assumed. Full base quantities follow the actual assessment; decorative block choice does not establish pavement capacity.
Charging basis to confirm: square metre. 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 |
|---|---|---|---|
| Paving purchase area allowance, square metres | 11 | KSh 1,500.00 | KSh 16,500.00 |
| Base/bedding/edge provisional lot | 1 | KSh 8,500.00 | KSh 8,500.00 |
| Crew labour hours | 24 | KSh 400.00 | KSh 9,600.00 |
| Compaction/tool allocation | 1 | KSh 2,200.00 | KSh 2,200.00 |
| Transport/spoil provisional allocation | 1 | KSh 2,600.00 | KSh 2,600.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 39,400.00 |
| Priced/accepted output | 10 example units |
| Assumed selling price | KSh 4,700.00 |
| Assumed invoice | KSh 47,000.00 |
| Difference before excluded costs and tax | KSh 7,600.00 |
Illustrative batch cost = 11 × 1500 + 1 × 8500 + 24 × 400 + 1 × 2200 + 1 × 2600 = KSh 39,400.00; cost per priced unit KSh 3,940.00. Revenue = 10 × KSh 4700 = KSh 47,000.00; pre-tax difference KSh 7,600.00. Eleven square metres is a fictional ten-percent block allowance. Base/spoil lots require measured physical takeoffs and actual disposal quotes. Published maker prices lacked clear sale units, so none are treated as exact pilot price evidence. Tax, premises, finance and actual rework must be added where applicable; no guaranteed earnings.
Check cash timing and a weaker outcome
TRAINING-0419: a fictional order for the scoped offer in section 01, using 10 priced units at KSh 4,700.00 each. Buyer group: Compound owners and small property managers. No buyer was contacted and no order was completed.
Teaching invoice = 10 x KSh 4,700.00 = KSh 47,000.00. The selected input lines in section 06 total KSh 39,400.00; their difference from this assumed invoice is KSh 7,600.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 14,100.00. The invoice balance is KSh 32,900.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 25,300.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 47,000.00. Cash against the selected example bill is KSh 7,600.00 before other payments. If a hypothetical 10% increase in the largest selected line (Paving purchase area allowance, square metres) adds KSh 1,650.00, the unchanged invoice leaves KSh 5,950.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 4,700.00 is a receivable. Cash collected is KSh 42,300.00 and collected cash less the selected bill is KSh 2,900.00. 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.
