Payment terms are the rules you and your customer agree to about when and how the money changes hands
Payment terms are not mysterious. They are straightforward an agreement between you and the person or business paying you about when they will pay, how they will pay, and what happens if they don't. Think of them as the contract that sits inside your invoice. Instead of saying "pay me whenever you feel like it," payment terms say "you will pay me by this date, in this way, or here is what occurs next."
When you write an invoice, you are asking someone for money. Payment terms protect you by making that request specific. They tell your customer exactly what you expect, and they give you a reason to follow up if the money does not arrive on time. Without clear terms, you end up chasing people down, unsure of whether they forgot, disagreed with the amount, or straightforward did not know when you needed the money.
Key Takeaways
- Payment terms are the written agreement about when a customer must pay you, how they must pay, and what happens if they do not pay on time.
- Common terms like "Net 30" mean the customer has 30 days from the invoice date to send you the money.
- Payment terms should appear on every invoice you send, so both you and your customer know what to expect.
- If a customer does not pay by the date in your terms, you have a documented reason to charge a late fee or stop working with them.
The most common payment term structures
Net 30 is the most common term you will see. It means the customer has 30 days from the invoice date to pay you. If you invoice them on January 1st, they owe you the money by January 31st. "Net" straightforward means the full amount with no discounts.
Other common terms follow the same pattern: Net 15 gives them 15 days, Net 60 gives them 60 days, and Net 90 gives them 90 days. Some businesses use Due on Receipt, which means the payment is due as soon as they receive the invoice—usually within a few days. A few use 2/10 Net 30, which means "if you pay within 10 days, you get a 2 percent discount, but the full amount is due in 30 days anyway."
You choose the terms based on who you are working with and what you can afford. If you are a freelancer or small business with tight cash flow, you might use Net 15 or Due on Receipt. If you are working with a large company that processes invoices slowly, you might agree to Net 60 to keep the relationship.
Where payment terms appear and what they do
Payment terms live on your invoice, usually near the top or bottom where they are straightforward to spot. They should be printed clearly so there is no confusion. When you send an invoice, you are saying "I did this work" and "here is when I need to be paid for it." The terms are the second part of that sentence.
Having terms in writing protects both of you. Your customer knows exactly when they need to pay and can plan their budget around it. You know when to expect the money and when it is reasonable to send a reminder. If 35 days pass and they have not paid a Net 30 invoice, you have a legitimate reason to follow up—they are now late.
Terms also give you grounds to charge a late fee if you decide to. Many small businesses add language like "1.5 percent monthly interest on unpaid balances after the due date" to their invoices. That fee only applies if you have stated it in your terms first. A customer cannot claim surprise if you charge them for being late when you told them the cost of being late upfront.
How to choose terms that work for your situation
Start by thinking about your own cash flow. How long can you wait for money before you run short? If you pay your suppliers weekly or have regular expenses, you need faster payment. If you have savings or other income, you can afford to wait longer. That answer tells you what terms to offer.
Then think about your customer. A large company with a finance department might need Net 60 because that is how their payment system works—they batch invoices and pay them on a schedule. A small business or individual customer might prefer Net 30 or Net 15 because they do not have the same delays. You can offer different terms to different customers, or you can have a standard term and negotiate when needed.
Write your terms clearly and include them on every invoice. Do not assume a customer remembers what you agreed to verbally. The invoice is the record. If you ever need to follow up on a late payment or take further action, that written term is your proof of what you asked for.
What happens when a customer does not pay by the due date
If a customer does not pay by the date in your terms, you have a few options. The first is to send a polite reminder—many people straightforward forget or miss the date. A straightforward email saying "I noticed your invoice from [date] is now due. Could you send payment by [new date]?" often works.
If they still do not pay, you can charge the late fee you stated in your terms, if you included one. You can also stop working with them until the invoice is paid. Some businesses require payment in full before starting new work for a customer who has been late before. None of these steps are mean or unfair—you are enforcing the agreement you both signed.
If a significant amount of money is involved and the customer refuses to pay, you may need to pursue the debt through small claims court or with a collection agency. That process is expensive and time-consuming, which is why clear payment terms and early follow-up matter so much. Most customers pay when reminded. The ones who do not usually have a reason, and a conversation often solves it faster than a legal threat.
Payment terms versus payment methods
Do not confuse payment terms with payment methods. Terms are about when you get paid. Methods are about how you get paid—whether by check, bank transfer, credit card, PayPal, or cash. You can have Net 30 terms and accept payment by any method your customer prefers. The terms say "you have 30 days," and the method says "send it this way."
Some payment methods are faster than others. A bank transfer might clear in one business day. A check might take a week to arrive and clear. A credit card payment might have a fee attached. You can choose methods that work for you, but the terms stay the same. If you invoice on January 1st with Net 30 terms, the payment is due by January 31st whether it arrives by check or transfer.
Frequently Asked Questions
What is the difference between Net 30 and Due on Receipt?
Net 30 gives the customer 30 days from the invoice date to pay. Due on Receipt means payment is due when ready when they receive the invoice, usually within a few days. Due on Receipt is faster but may make some customers uncomfortable if they are used to longer terms. Net 30 is more standard and gives customers time to process the invoice through their system.
Can I change payment terms after I send an invoice?
You can ask, but the customer is not required to agree. Once you send an invoice with specific terms, that is the agreement. If you need to change the terms, you should send a new invoice or get written confirmation from the customer that they accept the new terms. Changing terms without agreement can damage the relationship.
What if a customer asks for Net 60 but I need the money faster?
You can negotiate. Offer Net 45 as a middle ground, or offer Net 60 with a discount for early payment (like 2/10 Net 60, meaning 2 percent off if they pay in 10 days). You can also require a deposit upfront and Net 30 for the balance. The terms are negotiable—you do not have to accept what they ask for.
Should I charge a late fee, and how much?
That is your choice. A late fee encourages on-time payment and compensates you for the delay. Common amounts are 1 to 1.5 percent per month of the unpaid balance. State the fee clearly on your invoice before you charge it. Some customers will push back, so decide in advance whether the fee is worth the relationship risk.
What if a customer says they never received the invoice?
Keep records of when you sent it and how. If you email invoices, your sent folder is proof. If you use invoicing software, it usually tracks delivery. Ask the customer for their correct email or mailing address and resend it. Once they have received it, the payment clock starts again from that date, not from when you originally sent it.
