Every recovered pound should trace back to the cost that caused it.
Budget, apportionment, expenditure, reconciliation and dispute on one record. Apportionment is held as a rule rather than a typed share, so a reconciliation can be rebuilt line by line years after the year closed.
Service charge disputes are rarely about the money. They are about the working: which cost was included, on what basis it was shared, whether the invoice belongs to this schedule, and why the estimate and the actual differ by eleven per cent.
Residention keeps the working. Costs sit against the property and the schedule. Apportionment is a rule the platform applies. Reconciliation reads the real ledger rather than a re-keyed summary, and a dispute is raised against the specific line it concerns.
