Invoice Payment Terms Explained: Net 30 & More

Invoice payment terms tell the customer when payment is due and, usually, how to pay. The best wording is the wording both parties already agreed, paired with an exact calendar due date on the invoice.

This guide explains common shorthand. It does not decide which term is legally valid for a particular contract or jurisdiction.

Payment-term quick reference

The date examples below assume an invoice date of July 15, 2026 and count calendar days. The DraftFort generator uses the same date convention for its Net presets.

Term	Plain-English meaning	Example due date
Due on Receipt	Payment is due when the customer receives the invoice	July 15, 2026 in the generator
Net 7	Due 7 calendar days after the invoice date	July 22, 2026
Net 10	Due 10 calendar days after the invoice date	July 25, 2026
Net 14	Due 14 calendar days after the invoice date	July 29, 2026
Net 15	Due 15 calendar days after the invoice date	July 30, 2026
Net 30	Due 30 calendar days after the invoice date	August 14, 2026
Net 45	Due 45 calendar days after the invoice date	August 29, 2026
Net 60	Due 60 calendar days after the invoice date	September 13, 2026
Net 90	Due 90 calendar days after the invoice date	October 13, 2026
Custom	Due on the exact date you set	Your chosen date

If your agreement counts business days, starts after delivery or approval, or defines “receipt” differently, calculate the date under that agreement and use a custom due date.

Due on Receipt

Due on Receipt asks for payment when the invoice is received. It can still be ambiguous: an emailed invoice may be delivered immediately, while an internal approval system may record receipt later. Put an actual date beside the phrase and make sure the customer accepted the arrangement.

The generator sets the due date equal to the issue date for this preset. Change it to a custom date if that does not match your agreement or delivery method.

Net 7, Net 10, Net 14, Net 15, Net 30, Net 45, Net 60 and Net 90

“Net X” normally means the full balance is due X days after the agreed starting date. Many invoices use the invoice date as that start, but a contract might use delivery, acceptance or receipt instead.

Longer terms can fit a customer’s procurement cycle but leave the supplier waiting longer. Shorter terms can reduce that wait but only work when the customer has agreed and has a realistic approval path. There is no universally best number.

Avoid writing only Net 30. A clearer line is:

Net 30 - payment due August 14, 2026.

That preserves the shorthand and removes date-calculation ambiguity.

End of Month (EOM)

EOM usually points to the end of a month, but combined expressions can vary. Net 30 EOM might be interpreted as 30 days after month-end, while another agreement may define a different cycle.

DraftFort does not guess an EOM formula. Use Custom due date, calculate the date under the agreement and describe the trigger in the additional-terms field.

Early-payment discounts such as 2/10 Net 30

2/10 Net 30 commonly means the customer may deduct 2% if payment is made within 10 days; otherwise the full balance is due in 30 days. The wording should also state what date starts both periods and how partial or late payments are handled.

An early-payment discount has a real cost to the seller. Compare that cost with the value of receiving cash earlier, and document the arrangement before relying on it.

Deposits, milestones and staged billing

Projects can use an upfront deposit, progress invoices and a final balance. A photography agreement, for example, might set a retainer at booking and the balance before the event. Construction or consulting work might bill at named deliverables.

Those are not simple Net terms. Use a custom date for each invoice and identify the relevant milestone, contract or PO. The invoice should reflect the payment schedule rather than invent a new one.

Late fees and interest

Do not copy a percentage from a generic template. Whether a late fee or interest charge is enforceable can depend on the agreement, notices, rate caps, customer type and local law.

As one jurisdiction-specific example, the UK government says businesses can set their own payment terms and describes statutory timing and late-payment rights under UK rules. That guidance does not automatically apply elsewhere. Check the UK payment-obligations guidance or the relevant authority for your own transaction.

How the DraftFort due-date presets behave

The free invoice generator keeps the term and date in sync:

Choose a Net preset or Due on Receipt.
Set the invoice date.
The due date is calculated automatically in calendar days.
Change the invoice date and the due date recalculates.
Edit the due date directly and the selector switches to Custom due date.

The finished PDF prints both the term and exact due date. It can also include separate payment instructions, so the client sees when to pay and how to pay.

For terms the generator does not preset—or to compare calendar and weekday counting—use the invoice due date calculator, then enter the reviewed result as a custom date.

A practical way to choose terms

Start with the signed contract, accepted quote, PO or other agreement. Then consider the customer’s approval process, the delivery milestone and the cash- flow effect on the supplier. Confirm the term before work begins when possible.

Before sending the invoice:

Match the term to the agreement
Print the exact calendar due date
Identify the PO or milestone if relevant
Give a usable payment method and reference
Verify any discount, fee or interest wording
Keep the invoice with the related business records

For every other field, use the complete invoice checklist.
