Overview

Frequently asked questions

How do I calculate a daily accountant invoice?

Multiply billable hours by your hourly rate, add reimbursable expenses, subtract any discount, and then add applicable sales tax or VAT.

Should expenses be included in sales tax or VAT?

That depends on local tax rules and the nature of the expense. This calculator applies the entered tax rate to the discounted subtotal, including expenses.

What counts as billable time for an accountant?

Billable time commonly includes client work such as bookkeeping, tax preparation, reconciliations, meetings, reporting, and advisory work when permitted by your engagement terms.

Can I use this calculator for fixed-fee work?

Yes. Enter 1 billable hour and use the hourly rate field as the fixed daily fee, or choose figures that produce the agreed pre-tax amount.

Does the invoice total include withholding tax?

No. The calculator adds only the sales tax or VAT rate you enter. It does not calculate withholding tax, income tax, or other deductions.

Should I apply a discount before or after VAT?

In many cases, a discount reduces the taxable invoice amount before VAT or sales tax is calculated. Confirm the required treatment for your location and invoice type.
