Sending an invoice starts a timer. Exactly how long that timer runs dictates the entire financial reality of your business. Push for terms that are too short, and you risk alienating major enterprise clients. Agree to terms that are too long, and you will suddenly find yourself scrambling to make payroll despite having record sales on the books.
Invoice payment terms define how many days your customer has to pay you after you deliver the goods.[1] Usually, it is just a tiny phrase at the bottom of a PDF like “Net 30.” In reality, those few letters are the biggest lever you possess for managing working capital.
Figuring out how to negotiate and finance these terms makes the difference between scaling smoothly and operating in a constant cash-flow panic.
Breaking Down the Standard Timelines
Look at the definitions provided by the US Chamber of Commerce or big banks like J.P. Morgan, and you will notice a few rigid patterns across B2B contracts.[2][3]
Net 30 is the workhorse of the business world. Your client must settle the invoice within 30 days. It works because it gives accounts payable teams enough time to process the paperwork without completely destroying the seller’s cash reserves.
Net 60 and Net 90 stretch that window to two or three months. Massive corporate buyers demand these timelines. If you want to land a huge enterprise contract, you almost certainly have to swallow Net 60. The downside is brutal. You are effectively locking up your own operating cash for a quarter of the year.
Net 15 or Due on Receipt (DOR) requires payment immediately. You use these for small transactions or clients with terrible credit. Enforcing them on large corporate buyers is a great way to lose a deal.
Early Payment Discounts serve as a smart compromise. Write “2/10 Net 30” on your invoice, and your customer receives a 2% discount for paying within 10 days. If they ignore the discount, they owe the full amount in 30 days. It gives them a financial reason to pay you faster.
| Term | Cash Flow Impact | Client Perception | Best Fit For |
|---|---|---|---|
| Due on Receipt | Excellent | Strict | High-risk clients, small projects |
| Net 30 | Good | Standard | Everyday B2B relationships |
| Net 60 | Challenging | Accommodating | Enterprise software, large contracts |
| Net 90 | Brutal | Highly accommodating | Global enterprises, construction |
The Direct Hit to Your Working Capital
Recognising revenue is not the same thing as holding cash. You can log a £100,000 deal the second you hit send on the invoice. But if that PDF says Net 60, you cannot access the funds for 2 months.
That timing gap creates immense strain. You pay your suppliers, cloud providers, and staff on a Net 30 or shorter cycle. If cash goes out in 30 days but comes back in 60 days, you are literally bankrolling your customer’s operations with your own money.
Growing fast actually makes this worse. The team at Phoenix Strategy Group points out that as sales climb, the volume of cash trapped in accounts receivable climbs with them.[4] Imagine a software start-up generating £500,000 a month on Net 60 terms. They constantly have £1 million locked away and unusable. They look wealthy on paper, but cannot afford office rent.
This squeeze is exactly why founders spend time figuring out how to unlock cheaper working capital.
What is Normal in Your Industry?
You cannot dictate terms in a vacuum. Attempting to force Due on Receipt timelines in an industry that runs on Net 60 will cost you clients immediately.
In tech, Net 30 to Net 60 rules the day. Enterprise software buyers routinely push for 60 days of free use on large annual licences. Recruitment firms usually operate on Net 30 for temp placements. Manufacturing and construction see some of the longest payment cycles, with Net 60 or even Net 90 being completely normal among major contractors.
The Big Trade-Off
Setting your terms requires balancing the demands of your sales team against the panic of your finance department.
Short-term terms keep you liquid. You get paid fast. You lower the risk of default. You keep cash handy to reinvest. The problem is that being too strict alienates big buyers who operate on rigid accounts payable schedules.
Long-term terms help you sell. Stripe points out that giving clients extra time builds loyalty and helps you win bids against competitors.[5] But handing out Net 60 terms without a capital backup plan will paralyse your daily operations.
| Your Situation | The Playbook | The Reasoning |
|---|---|---|
| New client, unknown credit | Net 15 or Due on Receipt | Limits your exposure until they prove reliable. |
| Bidding on an enterprise deal | Net 60 | You have to match corporate standards to win. |
| Scaling fast, burning cash | Net 30 | Keeps the working capital engine moving. |
| Industry standard is Net 90 | Match it, add a 2/15 discount | Stays competitive while begging for fast cash. |
Managing Terms and Bridging the Gap
Payment timelines are a negotiation. You do not have to accept the first demand a buyer makes.
Look at the deal size. If an invoice is under £1,000, Net 15 works fine. If it is a £50,000 contract, clients expect breathing room. Always run a credit check before handing out 60 days of free financing to a new buyer. Just because someone asks for Net 90 does not mean they get it. Often, demanding 90 days is a glaring red flag that the client is having cash flow problems.
If you absolutely have to accept long terms to win a massive deal, you need a strategy to cover the resulting cash gap. This is exactly where invoice finance proves its worth.
Instead of staring at the calendar for two months waiting for a Net 60 invoice to clear, you use a facility to advance up to 95% of the cash within 24 hours. The provider waits for the client to pay the bill. You get the immediate capital you need to keep operating. You can offer generous payment terms to your buyers without wrecking your liquidity.

Payment Terms FAQs
What makes Net 30 different from 2/10 Net 30?
Net 30 means the full amount is due in 30 days. The “2/10 Net 30” tag is a discount offer. The buyer takes 2% off the bill if they pay within 10 days. If they skip the discount, they owe the full amount on day 30.
Can I switch terms on clients I already have?
Yes, but communication is everything. You cannot alter the terms of an invoice you have already sent. You have to update the contract or send a notice outlining the new billing timeline.
What do I do when a customer ignores the due date?
Build a strict collection process. Send a reminder a few days before the deadline. Follow up the minute it goes past due. If your contract allows it, legally add interest charges to the late debt.
Does using invoice finance to cover Net 60 look bad to my buyers?
Not if you use confidential discounting. With a confidential setup, your clients never realise a finance provider is involved. They pay into a trust account in your name exactly as they always have.
Stop Waiting 60 Days for Your Cash
Winning an enterprise contract shouldn’t punish your bank account. If Net 60 or Net 90 terms are destroying your working capital, invoice finance fixes the timeline instantly.
