Invoice Late Fee
Late payments are the most common cash flow problem freelancers face. Charging a late fee — and stating it clearly on your invoice — both compensates you for the delay and creates an incentive for clients to pay on time. Our late fee calculator computes the interest due on overdue invoices using either a flat fee, a percentage of the invoice, or a daily compound rate.
