Reimbursement and allowance are not the same even though they are sometimes used as synonyms. Employees who are given an allowance receive payments ahead of time and can use it for transportation without having to wait. This strategy is frequently linked to accidental inaccuracy in your accountable plan which is why it may not be the best option. Requiring employees to file mileage reports can help decrease this inaccuracy, but it also adds to the amount of paperwork that may not make some employees happy. While mileage reimbursement has its drawbacks, businesses may automate the entire process by using an app such as Driversnote.
