What are payment terms and what’s standard?

A payment term is the time frame in which your client must pay your invoice. The average freelance payment terms in the UK range from 14 to 30 days. You can set your own rules, but if no written agreement exists, the statutory standard applies.

Why freelance payment terms matter

As an independent professional, you likely have limited cash reserves. Extended payment deadlines can harm your liquidity and cause unnecessary stress. Choosing realistic freelance contract payment terms helps you keep up with expenses, maintain stability, and stay financially secure.

Legal payment terms for freelancers in the UK

UK law limits how long payments can take. If no specific agreement is made, businesses must pay within 30 days, with a maximum of 60 days allowed if both sides agree in writing and it isn’t unfair.
Public sector organisations are legally required to pay invoices within 30 days, while consumer clients have no fixed legal period – meaning you can set a fair and reasonable term yourself.

Payment terms by type of client

Business Clients (B2B)

For business transactions, the usual term is 30 days. A longer period (up to 60 days) is possible if both parties agree in writing. However, many freelancers choose shorter freelance invoice payment terms, such as 14 or 30 days, to protect their cash flow.

Consumers (B2C)

There’s no fixed legal term for consumers, so you can decide what’s fair. Many freelancers prefer to set 14‑day or 30‑day terms to keep payments moving.

Government and large corporations

Public authorities must pay within 30 days, and large companies are required by UK law to pay freelancers and small suppliers within the same timeframe.

Setting fair freelance invoice payment terms

To prevent misunderstandings, always document your freelance contract payment terms clearly. Include them in your contract and terms and conditions, mention the due date on your invoice, and specify when interest and collection fees will apply.

A 14‑day payment term is often considered reasonable for both parties and helps maintain a smooth business relationship.

What to do if a client pays late

Even with clear agreements, late payments can happen. Here’s what you can do:
Send reminders: Start with a friendly reminder. If there’s still no response, send a formal notice. For consumers, your first reminder must be free before charging late fees.
Charge late fees: After 30 days, you can add a statutory £ 40 late fee plus interest or recovery costs.
Apply statutory interest: You’re entitled to charge interest from the day after the payment was due.
Use a collection agency: If reminders don’t work, escalate to a professional agency.

Practical tips for better cash flow

Send clear invoices and terms

A clear, well‑structured invoice avoids confusion. Always include your freelance invoice payment terms, bank details, and any penalties for late payments. Attach your general terms and conditions to every quote or invoice.

Use shorter payment terms

Shorter deadlines – such as 14 days – are common in the UK and help you see early whether a client intends to pay on time.

Go digital

Send your invoices electronically to ensure they reach your client immediately. The delivery date marks the start of your payment period. Use software to track incoming payments and respond quickly to overdue invoices.

Stay proactive

Monitor your accounts receivable closely. Follow up the moment a payment becomes overdue.
