Sweet potato growing 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 2,500.00 invoice against KSh 1,325.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for sweet potato growing. 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 sweet-potato order: a breakfast vendor takes 50 kg of whole roots of one approved variety for boiling and roasting, delivered in five 10 kg net crates. It wants the cooked texture demonstrated in a trial, manageable portion sizes and sound skins. Orange, white and purple flesh types must not be substituted without approval. Provide a variety-and-lifting card showing planting source, trial block, harvested kilograms, cut or broken roots, size grades and accepted net delivery.
Charging basis to confirm: accepted kilogram. 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 |
|---|---|---|---|
| Named sweet-potato planting pieces, each | 100 | KSh 2.00 | KSh 200.00 |
| Lifting and sorting, worker hours | 5 | KSh 150.00 | KSh 750.00 |
| Crate hire, crate-delivery uses | 5 | KSh 25.00 | KSh 125.00 |
| Vendor delivery, return trip | 1 | KSh 250.00 | KSh 250.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 1,325.00 |
| Priced/accepted output | 50 example units |
| Assumed selling price | KSh 50.00 |
| Assumed invoice | KSh 2,500.00 |
| Difference before excluded costs and tax | KSh 1,175.00 |
Invented selected inputs total KSh 1,325, or KSh 26.50/kg across the assumed 50 kg accepted order. At assumed KSh 50/kg, receipts are KSh 2,500 and the difference KSh 1,175 before land, water, bed preparation, earlier crop care, tools, management, finance and failed establishment. One hundred planting pieces are only a cost assumption; no root yield per piece is predicted. If a fictional 60 kg lifting loses 10 kg to cuts and rejected grades, recovery is 83.33% in that scenario. Actual planting-material, labour, crate and transport quotes must replace these assumptions, and the full crop cycle must be costed before setting prices.
Check cash timing and a weaker outcome
TRAINING-0020: a fictional order for the scoped offer in section 01, using 50 priced units at KSh 50.00 each. Buyer group: Markets and breakfast-food sellers. No buyer was contacted and no order was completed.
Teaching invoice = 50 x KSh 50.00 = KSh 2,500.00. The selected input lines in section 06 total KSh 1,325.00; their difference from this assumed invoice is KSh 1,175.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 750.00. The invoice balance is KSh 1,750.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 575.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 2,500.00. Cash against the selected example bill is KSh 1,175.00 before other payments. If a hypothetical 10% increase in the largest selected line (Lifting and sorting, worker hours) adds KSh 75.00, the unchanged invoice leaves KSh 1,100.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 250.00 is a receivable. Cash collected is KSh 2,250.00 and collected cash less the selected bill is KSh 925.00. 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.
