Usually, the client gives the accountant a spreadsheet of the client's employees by name and/or ID with the hours they worked in each department for each pay item. Instead of entering hours manually for individual employees, you can import the data for all employees at the same time. Using this method, you can also specify fixed dollar amount overrides for deduction items.
If you're importing time entry data, you may want to define columns for employee ID, employee name, regular hours, overtime hours, pay rate, accruable benefits, and so forth. It's only necessary to map pay and deduction items for specified columns to the corresponding payroll items for the 1st import or when new (undefined) pay or deduction items are present in the spreadsheet. Because the client's spreadsheet format remains consistent across multiple imports, it's easy for the accountant to set up a template with predefined columns for ease of import. A typical time entry spreadsheet could look like this.
