Boiled egg vending 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 2,800.00 invoice against KSh 3,460.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for boiled egg vending. 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 boiled-egg vending day: ninety raw chicken eggs received, four cracked rejects, eighty-six prepared, eighty sold and six unsold/held. Sell one whole egg per order with food-use wrap; no raw salad or mayonnaise in scope. Egg cooking, shell/peeled handling, storage and holding follow a competent food plan. No salmonella-free claim from a clean shell or boiling appearance.
Charging basis to confirm: served egg. 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 |
|---|---|---|---|
| Raw eggs, each | 90 | KSh 15.00 | KSh 1,350.00 |
| LPG budget, kg | 0.8 | KSh 250.00 | KSh 200.00 |
| Potable water, litres | 50 | KSh 5.00 | KSh 250.00 |
| Food wraps, each | 80 | KSh 2.00 | KSh 160.00 |
| Preparation/service labour, hours | 6 | KSh 200.00 | KSh 1,200.00 |
| Stall-day allocation, day | 1 | KSh 300.00 | KSh 300.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 3,460.00 |
| Priced/accepted output | 80 example units |
| Assumed selling price | KSh 35.00 |
| Assumed invoice | KSh 2,800.00 |
| Difference before excluded costs and tax | KSh -660.00 |
Illustrative selected cost: KSh 3,460.00; cost per accepted sale unit: KSh 43.25; assumed receipts: KSh 2,800.00; difference against selected lines: KSh-660.00. All rates/counts hypothetical; negative selected result must remain visible. Unit one egg. Excludes cookware/holding equipment, cleaning, permits/food-handler obligations, condiments, tax and overhead. Six unsold earn no revenue and require actual disposition; no longer shelf life inferred.
Check cash timing and a weaker outcome
TRAINING-0129: a fictional order for the scoped offer in section 01, using 80 priced units at KSh 35.00 each. Buyer group: Commuters and workers buying ready-to-eat snacks. No buyer was contacted and no order was completed.
Teaching invoice = 80 x KSh 35.00 = KSh 2,800.00. The selected input lines in section 06 total KSh 3,460.00; their difference from this assumed invoice is KSh -660.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 840.00. The invoice balance is KSh 1,960.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 2,620.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 2,800.00. Cash against the selected example bill is KSh -660.00 before other payments. If a hypothetical 10% increase in the largest selected line (Raw eggs, each) adds KSh 135.00, the unchanged invoice leaves KSh -795.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 280.00 is a receivable. Cash collected is KSh 2,520.00 and collected cash less the selected bill is KSh -940.00. 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.
