Does anyone use the IRS mileage rate of $0.545? Core is rounding it to $0.55/mile, which is nominal, but the rounding throws off the accounting between employee reimbursements and client invoicing.
You can change the decimal settings for your company at the global level from the Global Settings > User Interface screen. The rate is set to 2 places of decimal by default; charge amount is set to 2 places of decimal, and so on. However, you can change these defaults by specifying your preferred decimal value for Rate and Units.
