Editorial update: 28 October 2026 · Business planning reference · Review scope
Use one accepted sale unit throughout
Work through a fictional KSh 5,000.00 invoice against KSh 4,975.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for viazi karai stall. 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 viazi-karai stall run: fifty portions, each four coated potato pieces, two hundred accepted pieces total. Serve no raw relish or sauce in this base scope. A cook-approved size reference defines the pieces; budget ten kg potatoes,1.5 kg gram flour and.1 kg declared spice mix as purchasing quantities, not a fixed recipe or 200-piece yield guarantee. Cooking/holding and oil/fire procedures require competent plan.
Charging basis to confirm: portion. 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.

Illustrative selected cost: KSh 4,975.00; cost per accepted sale unit: KSh 99.50; assumed receipts: KSh 5,000.00; difference against selected lines: KSh 25.00. All rates/inputs/count hypothetical and not a recipe. One sale unit four-piece portion. No sauce, egg or dairy added in this scoped model unless actual ingredient labels require declaration. Excludes cleaning, equipment, prior storage costs, approvals, tax and overhead; reconcile oil and unused inventory.
Check cash timing and a weaker outcome
TRAINING-0125: a fictional order for the scoped offer in section 01, using 50 priced units at KSh 100.00 each. Buyer group: Local snack buyers and takeaway customers. No buyer was contacted and no order was completed.
Teaching invoice = 50 x KSh 100.00 = KSh 5,000.00. The selected input lines in section 06 total KSh 4,975.00; their difference from this assumed invoice is KSh 25.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,500.00. The invoice balance is KSh 3,500.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 3,475.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 5,000.00. Cash against the selected example bill is KSh 25.00 before other payments. If a hypothetical 10% increase in the largest selected line (Cook/service labour, hours) adds KSh 160.00, the unchanged invoice leaves KSh -135.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 500.00 is a receivable. Cash collected is KSh 4,500.00 and collected cash less the selected bill is KSh -475.00. 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.
