Sweet potato flour production 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 10,400.00 invoice against KSh 12,705.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for sweet potato flour production. 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 sweetpotato-flour trial: eighty 500 g bags, forty kg accepted flour, from 150 kg fresh roots. Recovery is invented, not the historical research yield. Use identified sweetpotato, not cassava or mixed roots; qualified food technologist approves cleaning, slicing, drying endpoint, milling, packaging and storage. No vitamin-A/gluten-free claim without appropriate composition and cross-contact evidence.
Charging basis to confirm: pack. 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 |
|---|---|---|---|
| Fresh sweetpotatoes, kg | 150 | KSh 35.00 | KSh 5,250.00 |
| Drying equipment hire, days | 2 | KSh 700.00 | KSh 1,400.00 |
| Milling service, dried input kg | 45 | KSh 15.00 | KSh 675.00 |
| Half-kg bags, each | 80 | KSh 8.00 | KSh 640.00 |
| Labels, each | 80 | KSh 3.00 | KSh 240.00 |
| Processing/packing labour, hours | 16 | KSh 200.00 | KSh 3,200.00 |
| Electricity, kWh | 20 | KSh 30.00 | KSh 600.00 |
| Delivery, trip | 1 | KSh 700.00 | KSh 700.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 12,705.00 |
| Priced/accepted output | 80 example units |
| Assumed selling price | KSh 130.00 |
| Assumed invoice | KSh 10,400.00 |
| Difference before excluded costs and tax | KSh -2,305.00 |
Illustrative selected cost: KSh 12,705.00; cost per accepted sale unit: KSh 158.81; assumed receipts: KSh 10,400.00; difference against selected lines: KSh-2,305.00. All rates, two hire-days, 45 kg dried mill input and 40 kg sale flour hypothetical. Two days is an equipment budget, not a drying endpoint or completion guarantee. Negative cash result remains visible. Excludes validation/testing, potable water/cleaning, facility/compliance, tax and overhead; no nutritional claim.
Check cash timing and a weaker outcome
TRAINING-0114: a fictional order for the scoped offer in section 01, using 80 priced units at KSh 130.00 each. Buyer group: Bakers and specialist ingredient retailers. No buyer was contacted and no order was completed.
Teaching invoice = 80 x KSh 130.00 = KSh 10,400.00. The selected input lines in section 06 total KSh 12,705.00; their difference from this assumed invoice is KSh -2,305.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 3,120.00. The invoice balance is KSh 7,280.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 9,585.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 10,400.00. Cash against the selected example bill is KSh -2,305.00 before other payments. If a hypothetical 10% increase in the largest selected line (Fresh sweetpotatoes, kg) adds KSh 525.00, the unchanged invoice leaves KSh -2,830.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 1,040.00 is a receivable. Cash collected is KSh 9,360.00 and collected cash less the selected bill is KSh -3,345.00. 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.
