First establish the period, rate source, readings and which charges are fixed. The process below helps create a clear record that can be reviewed and compared later.
Record observable facts, dates and sources for figures. Do not replace evidence with an assessment of responsibility.
Step-by-step process
1. Define the period
Set the exact start and end of the settlement. Do not mix consumption from different occupants.
2. Separate usage and fixed charges
Calculate unit consumption separately from standing charges, advances, adjustments and other bill components.
3. Include advances paid
Show the calculated cost, total advances and resulting credit or balance due.
4. Keep the source
Retain the bill or manager statement. A calculator should reproduce the arithmetic, not replace the source record.
What to check before finishing
- Every figure has a unit, period or source.
- Photos and notes can be matched to a specific location.
- Both parties retain the same file or printout.
- Disputed or uncertain items are marked rather than hidden.
Practical example
Instead of one vague note saying “property in good condition”, the record contains the room, exact item, observation, date, photo and—where money is involved—a separate calculated entry. Months later, the parties do not need to reconstruct events from memory.
