Water filter maintenance in Kenya: Planning Worksheets and Source Register
Editorial update: 28 October 2026 · Business planning reference · Review scope
Keep records that answer a specific question
Use a buyer brief, quotation comparison, acceptance record and cash ledger matched to water filter maintenance.
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.

An invented invoice-and-collection record
TRAINING-0393: a fictional order for the scoped offer in section 01, using 1 priced units at KSh 6,500.00 each. Buyer group: Households and small offices with identifiable filter models. No buyer was contacted and no order was completed.
Teaching invoice = 1 x KSh 6,500.00 = KSh 6,500.00. The selected input lines in section 06 total KSh 5,350.00; their difference from this assumed invoice is KSh 1,150.00 before excluded costs and tax.
For cash-timing practice only, suppose a buyer pays a 30% advance of KSh 1,950.00. The invoice balance is KSh 4,550.00. If the selected input bill is paid before the balance arrives, additional cash of KSh 3,400.00 is needed after applying the advance. The advance is counted once, not again at final collection.
These sample entries are not your actual job records. Keep names, contacts and payment references in private copies. The paid pack contains offline editable costing, operations and cash-planning tools; this public sheet explains how the records connect.
