What is an early payment discount?
Quick answer
An early payment discount is a small price reduction a seller offers if the buyer pays an invoice well before it is due. The common shorthand 2/10 net 30 means take 2 percent off if you pay within 10 days; otherwise the full amount is due in 30.

Why it matters for a small business
For the seller, the discount is a trade: give up a little margin to get cash weeks sooner and reduce the chance of a late payment. For the buyer, taking it can be one of the best returns available on spare cash, which is why many accounts payable teams schedule payments to catch every discount they are offered.
The terms have to be written down and applied consistently. If the invoice says nothing about a discount, a customer who deducts 2 percent has created a short payment someone must chase. If the policy exists, reminders and invoices should state it the same way every time. That is a place AI needs firm limits: it should repeat the discount you actually offer and never make one up to close a conversation.
In a real lesson: Build a Custom GPT That Writes Overdue Invoice Reminders
In Build a Custom GPT That Writes Overdue Invoice Reminders, Maple Street Bookkeeping, a made-up firm, states its terms in the GPT's instructions: "Invoices are due 30 days after the invoice date." There is no discount in those terms, so a correct reminder never mentions one.
The GPT also has the firm's collections policy attached as a knowledge file, Maple-Street-Collections-Policy.pdf, so it only offers payment options the firm really accepts. That is the right pattern for discounts too: put the real offer in a document the AI reads, and it will quote the offer instead of guessing.
If the firm decided to offer 2/10 net 30, the change would belong in the policy file and the invoice template, not in a one-off prompt. One source keeps every message consistent.

Common confusions
Early payment discount vs Net 30
Net 30 is the deadline. The discount is an optional reward for paying well before that deadline. 2/10 net 30 combines the two.
Early payment discount vs a credit memo
A discount is taken at payment time under terms agreed in advance. A credit memo reduces what is owed after the fact, often for a return or an error.
Tips
- Print the discount terms on the invoice itself, not only in the contract.
- Put any discount policy in the knowledge file your AI assistant reads.
- Tell AI never to offer a discount that isn't in your written terms.
