Rental management without spreadsheets

Spreadsheets are convenient at the start but quickly lose the link between a reservation, payment, item and employee. Multiple file copies create multiple versions of truth.

Signs it is time to move

• The same item is promised twice
• Balances are calculated manually
• History is corrected by deleting rows
• Only one employee understands the file
• Utilization and profit are hard to measure

Migrate in stages: clean reference data, import customers and items, reconcile active rentals and balances, then keep old spreadsheets as read-only archives.
