What Are Invoice Payment Terms and Why Do They Matter?
Payment terms define when and how a client is legally expected to settle their balance. Without explicit terms, clients default to their own schedule, which usually means waiting until the end of their monthly accounting cycle.
Clear payment terms establish expectations before work begins, establish a legal deadline for charging interest, and protect your working capital.
Invoices issued with 'Due on Receipt' or 'Net 14' have a 94% on-time settlement rate compared to just 64% for standard Net 30 corporate terms.

| 2/10 Net 30 | 2% discount if paid in 10 days, else net 30 | High-volume wholesale supply | Incentivizes early cash |
How to Structure Late Fee Clauses Legally
To enforce late fees, the penalty clause must be stated in your initial estimate or contract before work commences. A standard, legally accepted formula is:
'Payment is due within 14 days of invoice date. Accounts unpaid after the due date will accrue interest at the rate of 1.5% per month (or the maximum allowed by state law) plus all reasonable collection costs.'
You rarely have to actually charge a late fee. Simply stating '1.5% monthly late fee applies after 14 days' signals that you are an organized professional whose bills cannot be pushed to the bottom of the pile.
