Getting paid on time starts with a single decision made before any work begins: choosing the right payment terms. Yet many UK businesses fall back on vague agreements or unquestioned industry habits — and it costs them. Whether you run a small consultancy, a product business, or a growing SME, the terms you set on your invoices shape your cash flow, your client relationships, and your legal standing.
This guide explains what Net 30, Net 60, and other standard UK payment terms mean, how to choose between them, and how to make sure they hold up if a client is slow to pay.
Summary in brief:
- Definition: Payment terms specify when a buyer must pay a seller after an invoice is issued or goods and services are delivered.
- Net 30 vs Net 60: Net 30 requires payment within 30 calendar days of the invoice date; Net 60 allows 60 days.
- UK legal default: Under the Late Payment of Commercial Debts (Interest) Act 1998, B2B invoices with no agreed terms are due within 30 days.
- Cash flow impact: Shorter terms improve supplier liquidity; longer terms give buyers breathing room but slow incoming cash for those who supply them.
- Best practice: State your payment terms in writing — in your contract and on every invoice — to make them legally enforceable and remove any ambiguity.
What Are Payment Terms?
Payment terms define the conditions under which a buyer agrees to settle an invoice. They appear on purchase orders, service contracts, and invoices, and typically cover:
- When payment is due (for example, 30 or 60 days from the invoice date)
- Acceptable payment methods (bank transfer, direct debit, card)
- Consequences of late payment (statutory interest, penalty fees)
- Any early payment discounts for prompt settlement
For UK businesses, payment terms are not a formality. They form part of a legally binding commercial agreement. Getting them right protects your working capital and gives you firm ground to stand on if a dispute arises.
Common UK Payment Terms: A Plain-English Guide
Net 30
Net 30 means the invoice must be paid within 30 calendar days of the invoice date. According to Coface's 2025 UK Payment Survey, 37% of UK businesses use payment terms of 30 days or fewer — making it the most common payment window in B2B transactions.
When Net 30 works well:
- Established customer relationships where trust is already in place
- Service businesses billing on project completion
- Businesses that need a short, predictable cash conversion cycle
Drawbacks: For buyers with complex internal approval chains, 30 days can feel tight. For suppliers with lean operating budgets, even a 30-day gap creates pressure on working capital.
Net 60
Net 60 sets the payment deadline at 60 calendar days from the invoice date. It is more common in larger B2B transactions, manufacturing supply chains, and contracts with large corporate buyers or public sector organisations.
When Net 60 works well:
- Buyers who need time to process invoices through multi-stage approval
- High-value, infrequent deliveries where relationship flexibility matters
- Businesses with strong reserves or high margins that can absorb a longer cash gap
Drawbacks: A 60-day window doubles the exposure period for bad debt and puts real strain on suppliers' working capital — particularly for SMEs that cannot easily bridge the gap with credit or overdraft facilities.
Net 90 and Beyond
Net 90 terms appear in some manufacturing or large-retail supply chains.
Attention — Legal risk beyond 60 days
Under UK law, payment terms exceeding 60 days are subject to a fairness test: they must not be grossly unfair to the supplier, and both parties must have genuinely agreed to them with a clear, objective commercial reason. A buyer imposing extended terms unilaterally risks having those terms set aside by a court. If you are asked to accept Net 90 or beyond, seek written justification and legal advice before agreeing.
Good to know — Upcoming reform
The UK's Commercial Payments Bill (currently before Parliament, July 2026) will introduce a statutory maximum payment term of 60 days for all B2B contracts. Any term exceeding this cap will be automatically void and replaced by a 30-day implied term. Expected to come into force no earlier than 2027, it is the most significant overhaul of UK payment law in over 25 years. If you are using or being asked to accept terms beyond 60 days, this legislation will directly affect your contracts once enacted.
Other Variations to Know
Term | Meaning | Best for |
|---|---|---|
COD (Cash on Delivery) | Payment due at the point of delivery | New customers, high-risk accounts |
CIA (Cash in Advance) | Full payment before goods or services are delivered | Custom orders, high-value projects |
EOM (End of Month) | Payment due by the end of the calendar month in which the invoice was issued | Businesses with monthly billing cycles |
2/10 Net 30 | 2% early payment discount if paid within 10 days; full amount due in 30 | Encouraging early settlement without making it compulsory |
The UK Legal Framework: What the Law Says
The Late Payment of Commercial Debts (Interest) Act 1998 gives UK suppliers automatic rights when invoices go unpaid. Key provisions:
- If no payment terms are agreed, B2B invoices become due within 30 days of the invoice date or the date goods or services were delivered, whichever is later.
- Suppliers can charge statutory interest at 8% above the Bank of England base rate on overdue amounts.
- A fixed debt recovery compensation fee of £40, £70, or £100 applies automatically, depending on the size of the debt.
- Under Section 4 of the Act (as amended by the Late Payment of Commercial Debts Regulations 2013), payment terms exceeding 60 days are only valid if both parties have genuinely agreed to them and the extended date is not 'grossly unfair' to the supplier — a protection introduced by those Regulations when implementing EU Directive 2011/7/EU into UK law.
Good to know
Public sector bodies in the UK must pay supplier invoices within 30 days under the government's Prompt Payment Policy. If you supply the public sector, you are entitled to insist on this, regardless of what the buyer proposes.
Net 30 vs Net 60: Which Is Right for Your Business?
The right choice depends on your cash position, your customer base, and your sector. Here are the key trade-offs at a glance:
Net 30 | Net 60 | |
|---|---|---|
Cash received | Sooner | Later |
Buyer appeal | Standard, less flexibility | More attractive to large buyers |
Bad debt exposure | Shorter window | Longer window |
Credit management overhead | Low | Higher |
Working capital pressure | Lower | Higher |
Typical sector | Services, SME-to-SME | Manufacturing, retail, corporate |
The practical question to ask yourself is: how many days can your business operate comfortably on existing reserves if a client is slow to pay? If the answer is fewer than 45 days, Net 60 may put unnecessary strain on your finances without additional protection such as invoice financing or a credit line.
For new customers, starting with Net 30 — or requiring a deposit — is the lower-risk default. You can always extend terms once a relationship is established and payment behaviour is proven.

How Payment Terms Shape Your Cash Flow
Payment terms directly determine your Days Sales Outstanding (DSO) — the average number of days between raising an invoice and receiving the cash. A business consistently on Net 60 with on-time payers has a DSO of around 60. If payments routinely arrive late, that figure climbs further.
A high DSO ties up working capital: money that is technically yours but not yet in your account. That affects your ability to pay suppliers, cover payroll, and invest in growth.
One practical lever: offer an early payment discount. A 2/10 Net 30 arrangement — 2% off for payment within 10 days — encourages faster settlement and brings your effective DSO down without forcing buyers to change their standard processes.
Understanding how payment terms affect your broader financial position is part of sound cash flow management. For a full breakdown of strategies available to UK small businesses, see our guide to cash flow management.
Best Practices for Setting Payment Terms in the UK
State Terms in Writing — Every Time
Your payment terms should appear in two places:
- Your contract or service agreement, signed before any work begins
- Every invoice you raise, including the actual due date (not just "Net 30", but the specific date payment is expected)
Ambiguity is your liability. A client who claims they "were not aware" of your terms has little defence if they signed a contract that spelt them out clearly.
Good to know — Electronic signatures
Electronic signatures are legally valid in the UK under the Electronic Communications Act 2000. Using a digital signing tool means contracts are executed within minutes, with a complete audit trail. Your agreed payment terms are timestamped and undeniable — and work starts sooner.
Run Credit Checks Before Extending Longer Terms
Before agreeing to Net 60 or Net 90, check the buyer's credit profile using Experian Business, Creditsafe, or Companies House filings. Longer payment days amplify the cost of a bad debt. A 90-day outstanding invoice from a company in financial difficulty is a very different problem from a 30-day one.
Automate Your Invoice and Reminder Process
Many UK SMEs lose money not because clients refuse to pay, but because invoices fall through the cracks. Accounting software automates payment reminders before and after the due date — significantly reducing average collection times without requiring awkward manual chasing. See how accounting software can help you get paid faster and take the admin burden off your team.
Act Promptly When Terms Are Breached
The longer an overdue invoice sits, the harder it becomes to recover. A structured escalation sequence keeps you in control:
- Friendly reminder at 7 days past due
- Formal written notice referencing your contract at 14 days
- Statutory interest claim notification at 30 days
- Debt recovery or legal action if unpaid beyond 30–60 days

Before You Set Your Payment Terms — Checklist
Define your cash flow minimum
Know how many days you can operate without incoming payment before choosing Net 30 or Net 60.
Run a credit check on new buyers
Use Experian Business, Creditsafe or Companies House before extending terms beyond 30 days.
Write terms into the contract
Include the exact due date (not just "Net 30") in both the contract and every invoice.
Get the contract signed before work starts
Use a digital signing tool to avoid delays and create an immediate audit trail.
Set up automated payment reminders
Schedule reminders at 7, 14, and 30 days post-due date via your accounting software.
Lock In Your Terms Before Work Begins
The right payment terms are only effective when they are clearly agreed, properly documented, and consistently enforced. Net 30 is a practical default for most UK SMEs. Net 60 can work for larger clients and higher-value contracts, provided you have the financial cushion and a credit management process to match.
Whatever terms you choose, ensure they are written into a signed contract before a single piece of work is delivered. The faster that contract is signed, the sooner your payment clock starts — and the sooner that cash reaches your account.

Frequently Asked Questions
What is the standard payment term in the UK?
Net 30 is the most common B2B payment term in the UK. It is also the legal default under the Late Payment of Commercial Debts (Interest) Act 1998 when no terms have been formally agreed between the parties.
Can I legally enforce Net 60 or Net 90 terms?
Yes, provided both parties agree to them in writing. However, under Section 4 of the Late Payment of Commercial Debts (Interest) Act 1998 (as amended by the Late Payment of Commercial Debts Regulations 2013), terms beyond 60 days must not be grossly unfair to the supplier and must reflect a genuine commercial agreement.
What does 2/10 Net 30 mean?
It means the buyer receives a 2% early payment discount if payment is made within 10 days; otherwise, the full invoice amount is due within 30 days. It incentivises early settlement without making it compulsory.
Can I charge interest on late invoices without a contract clause?
Yes. Statutory interest of 8% above the Bank of England base rate applies automatically under the Late Payment of Commercial Debts (Interest) Act 1998, even without a specific clause in your contract. You can also claim fixed debt recovery compensation of £40, £70, or £100.
What payment terms should freelancers use in the UK?
Many UK freelancers work on Net 30 terms; shorter terms (Net 7 to Net 14) are increasingly common for independent workers who cannot easily absorb long payment gaps. Requesting a deposit of 30–50% upfront for larger or longer projects is also standard practice and significantly reduces exposure.
Do payment terms need to be in a signed contract to be enforceable?
Clear written terms in a signed contract are the strongest form of evidence. While statutory defaults exist, having terms agreed in writing — and signed by both parties before work starts — eliminates ambiguity and significantly strengthens your legal position.
