Editorial update: 28 October 2026 · Business planning reference · Review scope
Define what must be funded before the first order
Build a startup quotation schedule for Genuine compatible cartridge, Competent filter service provider, Clean handling supplies and log; separate setup, operating inputs and working cash.
This is a planning reference for water filter maintenance. 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: One manufacturer-specified cartridge service on an identified domestic drinking-water filter by a competent service provider. Confirm housing/head model and source-water suitability before ordering. Scope genuine compatible replacement, supported hygienic handling, commissioning and service log. Exclude universal purification claims, unknown housings, membrane/UV work outside competence and guarantees of potability without the applicable testing and supply assessment.
A quotation checklist for this business
| Resource | Exact request to price | Check before accepting the quote |
|---|---|---|
| Genuine compatible cartridge | Exact head/housing and treatment requirement supported by the manufacturer. | Verify source, seal, shelf-life markings and part number before opening. |
| Competent filter service provider | Model-specific hygienic service and commissioning competence. | Ask who assesses source water and when laboratory evidence is needed. |
| Clean handling supplies and log | Only manual-permitted supplies, protected replacement parts and complete identity records. | Avoid generic household disinfectants unless the actual manufacturer procedure authorises them. |
Keep the budget categories separate
- Genuine compatible cartridge: Exact head/housing and treatment requirement supported by the manufacturer. Confirm the quantity, landed quote and verify source, seal, shelf-life markings and part number before opening.
- Competent filter service provider: Model-specific hygienic service and commissioning competence. Confirm the quantity, landed quote and ask who assesses source water and when laboratory evidence is needed.
- Clean handling supplies and log: Only manual-permitted supplies, protected replacement parts and complete identity records. Confirm the quantity, landed quote and avoid generic household disinfectants unless the actual manufacturer procedure authorises them.
- Record equipment acquisition OR an appropriate use allocation, plus the full stock/minimum-order cash requirement; do not count both as the same per-job expense.
- Obtain actual labour, premises, transport, energy/water, rework, payment and ongoing overhead amounts relevant to this activity. Identify deposits, receivables and payment dates separately.
- Resolve the guide-specific evidence gaps listed in section 10. Any activity-specific permission, testing or specialist costs require actual scope and quotations, not an invented allowance.
What the selected teaching bill includes
| Selected line | Example quantity | Assumed rate | Selected cost |
|---|---|---|---|
| Cartridge purchase assumption | 1 | KSh 3,200.00 | KSh 3,200.00 |
| Provider service labour hours | 2 | KSh 650.00 | KSh 1,300.00 |
| Permitted hygienic supplies | 1 | KSh 250.00 | KSh 250.00 |
| Travel | 1 | KSh 500.00 | KSh 500.00 |
| Service record | 1 | KSh 100.00 | KSh 100.00 |
These selected lines total KSh 5,350.00. They are a fictional operating example, not the full cash needed to start water filter maintenance. Illustrative batch cost = 1 × 3200 + 2 × 650 + 1 × 250 + 1 × 500 + 1 × 100 = KSh 5,350.00; cost per priced unit KSh 5,350.00. Revenue = 1 × KSh 6500 = KSh 6,500.00; pre-tax difference KSh 1,150.00. Cartridge price is wholly illustrative and depends on the exact system. Lab tests, unusual contamination, extra parts and source-water remedial work are separately quoted. No drinking-water health outcome is priced as guaranteed. Tax, premises, finance and actual rework must be added where applicable; no guaranteed earnings.
Close the budget before spending
For each actual quotation, record the delivered quantity, specification, cash due date, hire/purchase option and quote expiry. Keep an unknown cost blank. Reusable equipment purchase, an appropriate use allocation and refundable deposits are different records; do not count the same item twice.
- Proposed job has not been field tested or independently reviewed by a practising operator.
- Obtain actual local rates and the exact product/material instructions before quoting or scheduling.
