Every fleet has a workbook that only one person understands. That person is on leave. The file is named something optimistic like “Accounts_Master_USE_THIS”. There is also “Accounts_Master_USE_THIS_old”. Both are open. Neither agrees with the bank.
The sheet can tell you a driver’s salary to the rupee. It cannot tell you whether Tuesday’s airport run made money after diesel, FASTag and the extra hour the client will dispute. Salary is a cell. Profit is a story the sheet refuses to finish.
People defend this setup because it is “flexible”. Flexible is a polite word for “we typed around the broken formula”. A professional ledger does not need a legend printed on the wall. It needs a trip, a cost and a margin that survive the person who built tab seven.
Ask the sheet who is profitable and it will blink. Ask Fleet the same question and it will answer from the trips you already logged, which is a low bar and somehow still an upgrade.
Keep Excel for the things Excel is good at. A festival seating plan. A cricket auction. Not the question of whether the Innova paid for itself this month.
