Budgets are set against accounts and cost centres, for a period. Actuals come from the ledger continuously, so variance is current rather than as-at-last-report.
Cost centres follow the structure Nest holds, so departmental reporting does not need a separate mapping table.
Because the budget lives in a spreadsheet and actuals live in the ledger, and someone joins them after the close. By the time a department sees its variance, the month it relates to is over.
Budget holders then manage on instinct for four weeks and react afterwards, which is not what a budget is for.
A budget holder sees overspend while there is still a month left to do something about it.
Committed spend from purchasing can be included, so a department that has ordered but not been billed sees the commitment rather than a comfortable-looking number.
It does not do scenario planning, rolling forecasts or driver-based modelling. It compares a budget you set against actuals as they arrive.
It also will not stop spending. Budgets report; approval thresholds in purchasing control.
Keep cost centres to the number finance actually reports on. A structure with more centres than reports will not be maintained past the first quarter.
Set budgets at the level decisions are made. A budget nobody owns is a number, not a control.
The ledger for actuals, purchasing for commitments, Nest for the cost centre structure. Where a cost centre maps to a team, the budget can be reported by team without anybody maintaining the correspondence.
