FAQ

How should I determine my invoice numbering system?

It is best to use a sequential numbering system (e.g., 001, 002, 003) or a date-based system (e.g., 2023-10-01) to keep your financial records organized and easy to audit.

What should I include in the payment instructions?

Include all necessary details for the client to pay you, such as your bank account number, routing number, or a link to your preferred online payment portal.

How do I handle late payments?

Clearly state your late payment policy in the "Notes" section of your invoice, specifying any interest fees or grace periods you choose to apply.

Should I include tax on my invoice?

Yes, if your business is registered for tax, you must include the applicable tax rate and the total tax amount as a separate line item to remain compliant with local regulations.
