Editorial update: 28 October 2026 · Business planning reference · Review scope
Use one accepted sale unit throughout
Work through a fictional KSh 24,000.00 invoice against KSh 20,600.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for toilet fitting 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: Replacement of one conventional non-powered floor-mounted toilet by a competent plumber after measuring the existing outlet and room. The customer approves the exact pan/cistern, seat and connector list. Exclude powered smart toilets, structural work, moving a soil stack and concealed leaks requiring wider repairs. Product supply is specified separately from plumbing labour.
Charging basis to confirm: installation scope. 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 |
|---|---|---|---|
| Toilet set purchase assumption | 1 | KSh 14,500.00 | KSh 14,500.00 |
| Plumber labour hours | 4 | KSh 650.00 | KSh 2,600.00 |
| Compatible connections/fixings | 1 | KSh 1,300.00 | KSh 1,300.00 |
| Fragile transport | 1 | KSh 1,500.00 | KSh 1,500.00 |
| Old unit authorised removal allocation | 1 | KSh 700.00 | KSh 700.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 20,600.00 |
| Priced/accepted output | 1 example units |
| Assumed selling price | KSh 24,000.00 |
| Assumed invoice | KSh 24,000.00 |
| Difference before excluded costs and tax | KSh 3,400.00 |
Illustrative batch cost = 1 × 14500 + 4 × 650 + 1 × 1300 + 1 × 1500 + 1 × 700 = KSh 20,600.00; cost per priced unit KSh 20,600.00. Revenue = 1 × KSh 24000 = KSh 24,000.00; pre-tax difference KSh 3,400.00. The unit price and all inputs are fictional. No electrical or soil-stack alteration is included. Tax, unexpected substrate repair and special disposal charges need separate confirmation. Tax, premises, finance and actual rework must be added where applicable; no guaranteed earnings.
Check cash timing and a weaker outcome
TRAINING-0382: a fictional order for the scoped offer in section 01, using 1 priced units at KSh 24,000.00 each. Buyer group: Landlords and homeowners replacing a sanitary fitting. No buyer was contacted and no order was completed.
Teaching invoice = 1 x KSh 24,000.00 = KSh 24,000.00. The selected input lines in section 06 total KSh 20,600.00; their difference from this assumed invoice is KSh 3,400.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 7,200.00. The invoice balance is KSh 16,800.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 13,400.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 24,000.00. Cash against the selected example bill is KSh 3,400.00 before other payments. If a hypothetical 10% increase in the largest selected line (Toilet set purchase assumption) adds KSh 1,450.00, the unchanged invoice leaves KSh 1,950.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 2,400.00 is a receivable. Cash collected is KSh 21,600.00 and collected cash less the selected bill is KSh 1,000.00. 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.
