Payment Terms Explained: Net 30, Due Dates & Discounts

Payment terms explain when payment is due, what starts the payment period, how to pay and any agreed conditions. Agree them before the work or order is accepted, then repeat them clearly on the invoice. Adding unfamiliar terms only when you send the bill can cause a dispute.

Net 30 commonly means full payment is due 30 calendar days after the invoice date. Your agreement may instead start the period at receipt or acceptance, so state the starting event and an actual due date.

Common terms and their meaning

Term	Practical meaning	Detail to make explicit
Due on receipt	Pay when the invoice is received	Receipt date and payment route
Net 7, 15, 30, 60 or 90	Full amount due after the stated number of days	Calendar or business days, and starting event
EOM	Payment at the end of the relevant month	Which month and the date
Net 30 EOM	Often 30 days after the invoice month’s end	Spell out the calculation; usage varies
2/10 Net 30	2% discount within ten days; full amount within thirty	Eligible amount and discount deadline
Cash in advance	Payment before the agreed work or dispatch	Amount and when work begins
Payment on delivery	Payment at delivery under agreed arrangements	Accepted payment method
Deposit plus balance	Part paid initially, remainder at a later stage	Amounts and milestone dates

Abbreviations save space but should not force the customer to infer your terms. For cross-border customers, write dates with the month name so “04/10” cannot be read two ways.

Calculate a due date: worked examples

These examples count calendar days after an invoice dated 4 October 2026. They do not include a special holiday, weekend or acceptance clause.

Agreed term	Calculation	Due date
Net 7 from issue	4 October + 7 days	11 October 2026
Net 15 from issue	4 October + 15 days	19 October 2026
Net 30 from issue	4 October + 30 days	3 November 2026
EOM of invoice month	Last date of October	31 October 2026
30 days after invoice month end	31 October + 30 days	30 November 2026

Net 30 is not the same as “one month later.” Month lengths differ. If payment is due fifteen business days after acceptance, use that specific rule instead of copying the Net 15 example.

In this invoice generator, numbered Net terms calculate from the invoice date. Due on receipt uses the issue date as the app’s starting assumption; change the date if actual receipt differs. Custom terms need a manually checked due date. The tool does not know when your customer opened an email or approved a portal submission.

Work out an early-payment discount

For an eligible $1,000 balance on 2/10 Net 30, a 2% discount is $20. Payment within the agreed ten-day window would be $980; otherwise $1,000 remains payable by the thirty-day deadline.

Before offering it, decide whether the discount applies before tax, to the invoice total or to selected charges, and how tax adjustments will be handled. Write that basis into the agreement. The example assumes the whole $1,000 is eligible and does not model tax.

Compare the $20 cost with your margin and need for earlier cash. A discount is optional, not a necessary feature of a professional invoice. The editor does not automatically apply a discount based on when money arrives; record the agreed adjustment and actual payment accurately.

Choose terms that fit the transaction

For a new or large project, consider an agreed advance or milestone schedule to limit the amount outstanding. For ongoing clients, ask about their approval cycle and PO requirements before choosing a due date. Shortening a label to Net 7 will not make a customer with an incompatible process pay in seven days.

Consider your delivery costs, ability to fund the interval and the customer’s agreed payment process. Revisit terms before future work if payments regularly arrive late; avoid retroactively rewriting the agreement for an issued invoice.

Sample wording to adapt

Ordinary invoice:

Payment of USD 850 is due on 19 October 2026, fifteen calendar days after the invoice date. Please use INV-0042 as the transfer reference. Payment instructions appear below.

Milestone project:

An advance of USD 300 is due on acceptance. The remaining approved charges are payable within fifteen calendar days after the completion invoice. Additional work requires written approval.

Optional early-payment discount:

A 2% discount applies to the eligible service amount if cleared payment is received by [date]. Otherwise the full amount is due on [date]. The eligible amount and any tax adjustment are [specify].

Replace bracketed text and agree the conditions with the customer. Keep the due date field, payment-terms label and detailed terms consistent.

Late fees and overdue invoices

There is no universal “1.5% per month” late fee. Contract terms, customer type and local law affect whether interest or fees can be charged. Adding a fee to an invoice does not automatically make it enforceable.

For UK commercial debts, GOV.UK explains when a payment becomes late and the statutory interest framework. Check those conditions rather than applying them worldwide or to consumer invoices.

Before escalating, confirm that the invoice reached the right person, the balance is correct and no query remains unresolved. Our payment reminder guide includes messages that do not assume a fee or legal remedy.

Before sending

Check the starting event, calendar or business days, explicit deadline, currency, payment reference, advance treatment and any discount conditions. Download and review the final invoice. The app calculates dates and totals from your inputs; it does not determine the legal terms of your transaction.
