Which system should expenses for professional development be submitted through?

Expenses for professional development should be submitted through Expensify because this platform is specifically designed for managing and processing expense reports efficiently. Expensify allows employees to track their expenditures related to training, workshops, and continuing education easily, making the reimbursement process more streamlined. It includes features such as receipt scanning and categorization of expenses, which are particularly helpful for accurately recording expenses incurred for professional development.

The other systems mentioned, like ADP and the Payroll System, primarily focus on payroll management and employee compensation rather than expense tracking. QuickBooks is primarily an accounting software mainly used for financial management and bookkeeping, not specifically tailored for expense reporting in the context of employee professional development.
