Understanding Payment Terms

Payment terms define when a buyer must pay for goods or services after receiving an invoice. They set clear expectations between sellers and buyers, reduce disputes, and help both parties manage cash flow. Choosing the right payment terms can mean the difference between getting paid on time and chasing overdue invoices for weeks.

For small businesses and freelancers, shorter terms such as Net 15 or Due on Receipt accelerate cash flow, while longer terms like Net 60 or Net 90 are common in industries where buyers need time to process goods before paying. Offering an early-payment discount — for example, 2/10 Net 30 — can incentivize faster payments without straining the buyer relationship.

Understanding how each term translates to a concrete due date is essential for accurate bookkeeping and for avoiding late fees. Use the calculator above to convert any payment term into an exact due date, or consult the reference table below for a quick overview of the most common options.
