Net 30 vs Net 60 vs Net 90: How to Choose Payment Terms in 2026

Net 30, Net 60 and Net 90 are the number of days a customer has to pay after an agreed start point, and the start point changes the answer as much as the number does. Monk runs terms, credit and collections as one invoice to cash system, so the term you granted, the behaviour it produced and the cash it delivered sit on the same record. Net 30 protects working capital and suits newer or smaller accounts, Net 60 is the common mid market norm, and Net 90 is usually the price of doing business with a large buyer who sets supplier terms centrally. The practical work is matching terms to the account, pricing what the cash costs you, and knowing how far the effective term drifts from the stated one.

Most terms discussions happen at the end of a sales cycle, under time pressure, with nobody in the room holding the working capital cost. The result is a book where terms reflect who asked hardest rather than who pays best, and where the due date bears little relation to when cash lands.

What do Net 30, Net 60 and Net 90 mean, and when does the clock start?

Each is a payment deadline counted in calendar days from a trigger, and that trigger can be the invoice date, the delivery date, the date a valid invoice is received, or the end of the month following.

Invoice date is the default in most contracts and the cleanest to administer. Delivery or receipt based terms move the start to an event the buyer controls, which is reasonable for goods and awkward for services. Read the phrase receipt of a valid invoice carefully, because it lets the buyer restart the clock by rejecting an invoice for a missing purchase order.

End of month terms make the largest difference and attract the least attention. Under Net 30 EOM, the clock starts at the end of the month of invoice, so an invoice dated 3 March is not due until 30 April, which is 58 days after issue rather than 30. Across a year of invoices issued evenly, EOM adds roughly fifteen days on average and up to twenty nine at the extreme. A buyer moving you from Net 30 to Net 30 EOM has taken half a month of your cash without changing the headline number.

Write the trigger into the contract and print the due date on the invoice as a date rather than a term. You cannot chase a customer who believes the clock started later than you do, and you cannot measure lateness without agreement on when the invoice became due.

Who asks for which terms, and how should terms differ by segment?

Terms mostly follow bargaining power and sector convention, so set a default per segment and adjust per account rather than negotiating each one from scratch.

Segment defaults are a starting position rather than a policy. Within any segment, the account's own record should move the term in both directions, so a customer that has paid on the day for two years can carry Net 45 while a same sized account that broke three promises last quarter goes to Net 15 with a deposit. Sizing the exposure alongside the term is covered in how to set customer credit limits.

What does each extra day of terms cost you?

Every day of terms is a day of sales financed out of your own balance sheet, so price it as the cash tied up multiplied by your cost of capital.

The arithmetic is simple enough to do in a meeting. One day of sales equals annual credit sales divided by 365, and your receivables balance is roughly one day of sales multiplied by DSO. Extending a customer from Net 30 to Net 60 therefore ties up thirty extra days of that customer's sales, permanently, for as long as the relationship lasts. Multiply that balance by whatever a dollar costs you, whether the rate on your facility or the return on what you would otherwise fund, and you have the annual cost of the concession.

Two costs get left out of that calculation. The first is risk, since an invoice at 90 days carries more chance of never being collected than the same invoice at 30, so longer terms raise expected bad debt as well as funding cost. The second is optionality, because cash committed to receivables cannot fund inventory, hiring or a downturn.

Terms feed DSO directly, and DSO is the number your board and your lenders read. Before granting an extension, work out what it does to DSO and say that number in the same conversation as the deal value. For the levers that pull it back, see how to reduce DSO.

How should you price an early payment discount?

Annualise it first, because the common discount structures are far more expensive than the rate on any facility you could draw instead.

The formula is the discount divided by the amount you still receive, multiplied by the year divided by the days you pulled the cash forward. For 2/10 Net 30 that is two over ninety eight, multiplied by 365 over twenty, or roughly 37% a year. Most people offering that discount believe they are giving away 2%.

The rule is visible down the table: the shorter the acceleration, the more the discount costs. Pulling cash forward by fifty days is defensible, pulling it forward by twenty rarely is unless you are short of cash and short of alternatives. Offer discounts by account, and only where the annualised rate sits below what the same cash costs you elsewhere.

Then police them. Unearned discounts, where a customer deducts the 2% and pays on day 40 anyway, are one of the most common leaks in B2B receivables. Set the rule in writing, apply the deduction back as a short pay, and chase it the same week rather than at year end when it has become a habit.

Why does the effective term diverge from the stated term?

Because the stated term starts a clock the buyer's process does not obey, and the gap between the two is routinely measured in weeks.

Five things stretch the term after you have agreed it. Submission comes first: across the receivables Monk manages, 92% of enterprise invoices must be submitted through a vendor portal or network rather than paid from an email, and an invoice rejected for a missing field has not been issued at all. Approval comes next, and where terms run from receipt of a valid invoice, none of that time counts against the buyer. Then the payment run, because a due date of the 3rd against runs on the 15th and 30th means the 15th at best. Then settlement, whether check float or a cross border wire. And finally deductions, where a partial payment reopens the cycle on the balance.

Measure the gap rather than assuming it. For each large customer, take the median days from invoice issue to cash received over the last six months and subtract the stated term. That difference is your terms gap, and it is the number for a renewal conversation, because a customer on Net 60 who consistently pays in 82 days is a Net 82 customer regardless of what the contract says.

Much of the gap is recoverable without renegotiating anything. Date invoices to land before the buyer's cut off for the next run, submit through the right channel the day you issue, and make sure the invoice passes validation first time, with the purchase order number, the correct entity and the supporting documents attached.

How do you negotiate terms, and what if a large customer extends them unilaterally?

Negotiate the whole package instead of the number, and treat an imposed extension as a pricing event rather than an administrative notice.

Terms are a form of financing, so trade them for something: a price that reflects the funding cost, a volume commitment, a deposit, milestone billing, or a direct debit mandate. A published menu works better than a case by case fight, because it prices the concession openly. Net 30 at list, Net 60 at a stated uplift and Net 90 for a committed volume gives the buyer a real choice and your sales team a defensible answer. Hold firm on the clauses that cost nothing to keep: the trigger date, a late payment charge, a dispute window requiring objections within a set number of days, and a bar on unilateral variation.

When the letter arrives announcing that all suppliers move to Net 90 next quarter, do not answer it from accounts receivable. Quantify the cost, then check the contract, since a signed agreement usually governs over a policy notice or purchase order text. Reply commercially with options rather than a refusal: the extension alongside a price adjustment, acceptance for a defined period pending review, acceptance in exchange for a volume commitment, or an early payment discount priced at its true annualised rate.

Watch for the supplier finance programme that often accompanies these letters, where the buyer's bank offers to pay you early at a discount. It can be a reasonable option, but be clear about what it is: you are paying a fee to keep the terms you already had, so compare its cost against the price increase you could have asked for instead.

What are the alternatives?

Where terms are the wrong instrument, several other structures move cash earlier without a fight over the number of days.

Deposits and milestone billing suit project work and change the shape of the exposure rather than the term. Annual or quarterly billing in advance suits subscriptions, and a modest discount for paying annually is usually far cheaper than 2/10 Net 30. A card on file with autopay, or a direct debit mandate, removes the payment run from the equation for smaller accounts. Credit insurance lets you offer longer terms to a marginal account without carrying the full loss.

On the financing side, receivables finance and factoring convert invoices to cash at a cost, and dynamic discounting lets a buyer choose how early to pay on a sliding scale that prices each day. Each belongs to a different situation, so choose deliberately rather than defaulting to longer terms because a buyer asked.

How does Monk handle this?

Monk sets terms from evidence rather than negotiation, by combining the payment behaviour it sees while running your collections with third party bureau signals.

Because Monk sends the invoices, chases them and applies the cash, it holds the record that decides a terms question: median days beyond terms, promises kept, disputes, deductions and the channel each customer pays through. It combines that with bureau data into a credit view, then suggests terms with the evidence attached, so an extension request is answered with the account's own history.

Because the view updates continuously, an account that starts slipping triggers a review before the next renewal. Julia, Monk's AI agent for Intelligent Collections, runs the follow up on accounts that drift, with a 24% higher response rate than standard dunning and 90% of collections resolved with zero human intervention. Teams on Monk see a 40% average reduction in DSO and save 26 hours a month. Monk has more than $2B in receivables under management, integrates with QuickBooks, NetSuite, Salesforce, HubSpot and Stripe, and is SOC 2 Type II compliant.

Where should you start?

Measure your terms gap this week, before changing a single contract.

Export the last six months of paid invoices for your twenty largest customers with three fields each: invoice date, due date and cash received date. Calculate the median days from issue to cash per customer, then subtract the stated term. Sort by the gap multiplied by the customer's annual revenue, and you have a ranked list of where your terms are fiction and what each one costs.

Then run two checks. Confirm which trigger each contract uses, because a customer on end of month terms holds roughly fifteen more days of your cash than the headline suggests. And annualise any early payment discount you offer, because it is often the most expensive financing on the books and nobody has priced it.

Frequently Asked Questions

What is the difference between Net 30, Net 60 and Net 90?

They are payment deadlines of 30, 60 or 90 days from an agreed start point, usually the invoice date. The higher the number, the longer the customer holds cash you have already earned and financed. The start point counts as much as the number, since delivery based or end of month triggers add weeks to the same headline term.

What does Net 30 EOM mean?

The clock starts at the end of the month in which the invoice is issued, so an invoice dated 3 March falls due on 30 April rather than 2 April. Across a year of evenly spread invoices, EOM adds around fifteen days on average and up to twenty nine at the extreme. It is a significant concession disguised as a formatting detail.

Which payment terms should I offer?

Set a default by segment, then adjust by the account's own payment record. Smaller customers can pay on receipt or Net 30 with a card or mandate on file, mid market accounts sit at Net 30 to Net 45, and enterprise buyers apply their own standard of Net 60 to Net 90. Move an account shorter after broken promises and longer after a sustained record of paying on time.

What does 2/10 Net 30 cost?

Roughly 37% a year. The calculation is the discount divided by the amount you still collect, multiplied by 365 divided by the days you pulled the cash forward, so two over ninety eight multiplied by 365 over twenty. Offer it only where you need the cash faster than your cost of capital, and police unearned discounts where customers deduct the 2% and pay late anyway.

How do payment terms affect DSO?

Directly, then indirectly. The stated term sets the floor, and the buyer's approval, portal submission, payment run and deductions add the rest. Compare median days from invoice to cash against the stated term, since the difference shows how much of your DSO is terms and how much is process.

What should I do if a customer extends payment terms unilaterally?

Quantify the working capital cost, check whether your signed contract governs over their policy notice, and respond commercially rather than from accounts receivable. Offer options: a price adjustment alongside the longer terms, acceptance for a defined period, a volume commitment, or an early payment discount priced at its true annualised rate. If a supplier finance programme comes with it, compare its fee against the price increase you could have asked for.

Are longer terms worth it to win a large account?

Sometimes, provided the cost is priced into the deal rather than absorbed silently. Work out the extra days of sales tied up, multiply by your cost of capital, add the higher risk of loss on older balances, and compare that with the margin on the contract. Size is not the same as reliability, and a large account on Net 90 that pays late is financing itself with your cash.
