Payment terms define the conditions under which a seller expects payment from a buyer. They specify when payment is due, what payment methods are accepted and whether any discounts or penalties apply. For UK businesses, setting clear payment terms is essential for managing cash flow and maintaining professional trading relationships.
Why payment terms matter
Payment terms directly affect a company’s working capital. Generous terms tie up cash in receivables, while tight terms can strain supplier relationships. Getting the balance right is one of the most important decisions in credit management.
Key impacts include:
- Cash flow predictability from consistent collection cycles
- Reduced late payments when terms are clearly communicated
- Stronger negotiating position in supplier and customer contracts
- Legal protection when disputes arise over overdue amounts

Common UK payment term structures
| Term | Meaning | Typical use |
|---|---|---|
| Due on receipt | Payment expected immediately | Retail, small orders |
| Net 7 | Payment due within 7 days | Service industries |
| Net 14 | Payment due within 14 days | Small business B2B |
| Net 30 | Payment due within 30 days | Standard UK B2B |
| Net 60 | Payment due within 60 days | Large contracts |
| Net 90 | Payment due within 90 days | Public sector, construction |
| EOM | End of month | Monthly billing cycles |
| 2/10 Net 30 | 2% discount if paid within 10 days, otherwise net 30 | Incentivised early payment |
Net 30 remains the most widely used payment term in UK B2B commerce. However, actual payment cycles often extend beyond stated terms, making credit control a continuous operational priority.
Early payment discounts
Some businesses offer early payment discounts to encourage faster settlement. A term like 2/10 Net 30 means the buyer can deduct 2% from the invoice total if they pay within 10 days, otherwise the full amount is due within 30 days.
Calculating the cost of not taking the discount
The annualised cost of missing an early payment discount is significant:
Discount % / (100% - Discount %) x 365 / (Full term - Discount period)
For 2/10 Net 30:
2 / 98 x 365 / 20 = 37.2% annualised
This means a buyer who does not take the 2% discount is effectively paying an annualised rate of over 37%. For this reason, many finance teams prioritise taking early payment discounts when cash allows.
Legal default under UK law
The Late Payment of Commercial Debts (Interest) Act 1998 establishes a statutory framework when payment terms are not explicitly agreed in a contract:
- The default payment period is 30 days from invoice date or delivery of goods/services, whichever is later
- If terms are agreed but exceed 60 days, they must be fair and reasonable
- In public sector contracts, the maximum payment term is generally 30 days
This means that even without a written agreement, UK businesses have a legal right to expect payment within 30 days. For more on what happens when payment is late, see our guide to late payment penalties.
Payment terms on invoices
Every UK invoice should clearly state its payment terms. This typically includes:
- Due date expressed as a specific calendar date
- Payment methods accepted such as BACS, Faster Payments, CHAPS or direct debit
- Bank details including sort code, account number and IBAN for international payments
- Early payment discount terms if applicable
- Late payment charges the business intends to enforce
Example payment terms clause
Payment is due within 30 days of invoice date. We accept payment by BACS, Faster Payments or CHAPS. Late payments will incur statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998.
Negotiating payment terms
When negotiating payment terms with customers or suppliers, consider:
- Customer creditworthiness assessed through credit checks and trade references
- Order size and frequency where larger or regular orders may warrant extended terms
- Industry norms since certain sectors have established conventions
- Your own cash flow requirements balancing competitiveness with liquidity needs
- Security such as requiring a deposit, staged payments or retention clauses
For high-value contracts, businesses often use a purchase order system that documents agreed terms before any invoice is raised.
Payment terms and cash flow management
Payment terms have a direct impact on days sales outstanding (DSO), a key metric for finance teams. Reducing DSO by tightening payment terms or improving collection processes frees up working capital.
| DSO scenario | Monthly revenue £100,000 | Cash tied up |
|---|---|---|
| Net 30 actual 30 days | £100,000 | £100,000 |
| Net 30 actual 45 days | £100,000 | £150,000 |
| Net 60 actual 60 days | £100,000 | £200,000 |
| Net 60 actual 75 days | £100,000 | £250,000 |
The difference between stated terms and actual payment behaviour often reveals the real cash flow picture. Tracking DSO against stated terms helps identify customers who consistently pay late and may need escalation through payment reminders.
Sector-specific payment term practices
Construction
The Construction Act (Housing Grants, Construction and Regeneration Act 1996) provides specific rules for payment in construction contracts, including:
- Mandatory payment schedules in contracts over a certain threshold
- Right to suspend work for non-payment
- Adjudication as a dispute resolution mechanism
Public sector
Public bodies in the UK are expected to pay within 30 days and report their payment performance. The Prompt Payment Code encourages signatories to pay 95% of invoices within 30 days.
Retail and e-commerce
Consumer transactions are typically paid at point of sale, so traditional payment terms are less relevant. However, buy now, pay later arrangements and trade credit between retailers and wholesalers follow standard B2B terms.
Recording payment terms in accounting
Payment terms affect how receivables and payables are aged in the accounting system. They determine:
- When revenue recognition triggers if tied to payment milestones
- Aged receivable reporting and overdue classification
- Cash flow forecasting accuracy
- Provisioning for doubtful debts based on payment history
Getting payment terms right at the invoicing stage reduces downstream accounting issues and supports cleaner financial reporting.
Common mistakes with payment terms
- Not stating terms on the invoice which weakens your legal position
- Using ambiguous language like “payment expected promptly” instead of a specific number of days
- Setting terms too long to win business without considering the cash flow impact
- Not enforcing terms which trains customers to pay late
- Ignoring the statutory framework when no explicit terms are agreed
Clear, consistent and enforceable payment terms form the backbone of effective credit control and healthy business cash flow.
