Why Decimal Hours Matter for Payroll & Billing
Payroll software, invoicing tools, and project management platforms almost universally expect time in decimal format. Entering 7.5 instead of 7:30 lets the system multiply by an hourly rate directly — no manual conversion needed.
For teams processing weekly timesheets, the difference between 7:30 and 7.5 might seem trivial — but across dozens of employees or hundreds of line items, manual conversion is a consistent source of errors.
