Audio cleanup 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 3,500.00 of selected cost lines; distinguish the invoice from collected cash.
This is a planning reference for audio cleanup 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 sample order: improve intelligibility of six two-minute interview recordings supplied by a community archive. Deliver six processed WAV files, untouched source copies and a short limitations log. The work targets steady fan hiss, obvious clicks and uneven listening level; it does not certify forensic authenticity or recover speech that was never recorded clearly. Provide a 20-second before-and-after pilot before accepting all twelve source minutes. Do not add generated replacement words without a separate transparent editorial agreement.
Charging basis to confirm: Processed audio minute. 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 |
|---|---|---|---|
| Assessment and cleanup hours | 4 | KSh 600.00 | KSh 2,400.00 |
| Export and quality review hours | 1.5 | KSh 600.00 | KSh 900.00 |
| Storage and transfer allocation | 1 | KSh 200.00 | KSh 200.00 |
| Calculation | Teaching result |
|---|---|
| Selected cost total | KSh 3,500.00 |
| Priced/accepted output | 6 example units |
| Assumed selling price | KSh 750.00 |
| Assumed invoice | KSh 4,500.00 |
| Difference before excluded costs and tax | KSh 1,000.00 |
Fictional cost is KSh 3,500 for six recordings, or KSh 583.33 each. Six sales units at KSh 750 produce KSh 4,500 revenue and KSh 1,000 pre-tax surplus before overhead and tax. These rates are not supplier evidence. If a file requires substantially more manual repair than the approved pilot, stop and re-scope instead of hiding extra time.
Check cash timing and a weaker outcome
TRAINING-0672: a fictional order for the scoped offer in section 01, using 6 priced units at KSh 750.00 each. Buyer group: Interviewers, trainers and creators with authorized recordings. No buyer was contacted and no order was completed.
Teaching invoice = 6 x KSh 750.00 = KSh 4,500.00. The selected input lines in section 06 total KSh 3,500.00; their difference from this assumed invoice is KSh 1,000.00 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 2,150.00 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 1,000.00 before other payments. If a hypothetical 10% increase in the largest selected line (Assessment and cleanup hours) adds KSh 240.00, the unchanged invoice leaves KSh 760.00 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 550.00. 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.
