Soil sample collection service 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 4,500.00 invoice against KSh 3,680.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for soil sample collection 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 one-farm collection visit for four separately mapped soil-management zones, producing four labelled samples for a named receiving laboratory and one chain-of-custody sheet. Sampling depth, subsample pattern, sample mass and preparation come from the laboratory's current instructions for the specific tests, not a guessed universal method. Laboratory analysis and agronomic interpretation are excluded from the collection fee unless separately itemized.
Charging basis to confirm: sample collection visit. 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 |
|---|---|---|---|
| Sampling and documentation labour, hours | 5 | KSh 300.00 | KSh 1,500.00 |
| Approved sample bags, each | 6 | KSh 50.00 | KSh 300.00 |
| Labels/forms, sheets | 8 | KSh 10.00 | KSh 80.00 |
| Sampling tool hire, day | 1 | KSh 300.00 | KSh 300.00 |
| Farm travel, return trip | 1 | KSh 1,000.00 | KSh 1,000.00 |
| Laboratory delivery, trip | 1 | KSh 500.00 | KSh 500.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 3,680.00 |
| Priced/accepted output | 1 example units |
| Assumed selling price | KSh 4,500.00 |
| Assumed invoice | KSh 4,500.00 |
| Difference before excluded costs and tax | KSh 820.00 |
Illustrative selected cost: KSh 3,680.00; cost per accepted sale unit: KSh 3,680.00; assumed receipts: KSh 4,500.00; difference against selected lines: KSh 820.00. All rates invented. One priced unit is one four-zone collection visit. Laboratory tests, interpretation, extra zones, specialist contaminated-land sampling, taxes and overhead are excluded. Historic web sample quantities are not current authorization; obtain written lab instructions and actual analysis charges.
Check cash timing and a weaker outcome
TRAINING-0081: a fictional order for the scoped offer in section 01, using 1 priced units at KSh 4,500.00 each. Buyer group: Growers wanting laboratory results rather than guesswork. No buyer was contacted and no order was completed.
Teaching invoice = 1 x KSh 4,500.00 = KSh 4,500.00. The selected input lines in section 06 total KSh 3,680.00; their difference from this assumed invoice is KSh 820.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,350.00. The invoice balance is KSh 3,150.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 2,330.00 is needed after applying the advance. The advance is counted once, not again at final collection.
On full collection, total receipts are KSh 4,500.00. Cash against the selected example bill is KSh 820.00 before other payments. If a hypothetical 10% increase in the largest selected line (Sampling and documentation labour, hours) adds KSh 150.00, the unchanged invoice leaves KSh 670.00 against that revised bill.
If the customer instead leaves 10% of the invoice unpaid, KSh 450.00 is a receivable. Cash collected is KSh 4,050.00 and collected cash less the selected bill is KSh 370.00. 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.
