Cash flow is the lifeblood of any trade business. You can be the best plumber, electrician, or builder in your area, but if money is not coming in on time, you will struggle to pay for materials, cover your van costs, and keep food on the table. Late payments are one of the biggest headaches for UK tradespeople, and the problem is far more common than most people realise.
According to the Federation of Small Businesses, over 50,000 small businesses close every year in the UK because of cash flow problems — not because they lack work, but because they cannot collect what they are owed quickly enough. If you have ever finished a job and then spent weeks chasing the money, this guide is for you.
Why Do Tradespeople Struggle with Cash Flow?
Before we look at solutions, it helps to understand why cash flow is such a persistent problem in the trades. The reality is that several factors stack up against you.
- You buy materials before you get paid: On most jobs, you are spending your own money on supplies before the customer has paid a penny. That gap between spending and receiving payment can stretch your finances thin
- Customers delay payment: Domestic customers sometimes forget, and commercial clients often push payment terms to 30, 60, or even 90 days
- Seasonal fluctuations: Many trades experience quiet periods where work dries up but bills keep coming. Landscapers, roofers, and decorators are particularly affected by seasonal demand. Read our guide on managing seasonal work in landscaping for more on this
- No formal invoicing process: Too many tradespeople rely on verbal agreements and handwritten notes, making it harder to chase payments professionally
- Underpricing: When your margins are razor-thin, even one late payment can tip you into the red. Check our plumbing pricing guide to make sure your prices actually cover your costs
What Payment Terms Should You Set?
Getting your payment terms right is one of the simplest things you can do to improve cash flow. The key is to be clear, upfront, and consistent.
For Domestic Customers
Payment on completion is the gold standard for residential work. The customer pays you when you finish the job, before you leave site. This eliminates the risk of chasing payment later and keeps your cash flow healthy.
- State on your quote: "Payment due on completion of works"
- Discuss it at the quoting stage so there are no surprises
- Offer multiple payment methods — bank transfer, card payment via SumUp or Square, or even cash — to remove any excuse for delay
For Commercial Clients
Business customers typically expect 14 to 30-day payment terms, which is standard practice. However, you should negotiate for the shortest terms possible.
- 7 days: Ideal but hard to negotiate with larger companies
- 14 days: A reasonable middle ground that most commercial clients will accept
- 30 days: Only agree to this for established clients with a proven payment history
- Never agree to 60 or 90 days: These terms are designed to benefit the client at your expense. If a company insists on 60+ day terms, factor the cost of waiting into your price
Tip: Always put your payment terms in writing on your quote and your invoice. A verbal agreement is hard to enforce. When you send a professional quote through an app like QuoteGuru, your terms are documented automatically.
How Much Deposit Should You Take?
Taking a deposit before starting work is standard practice across the trades, and any customer who refuses to pay one should raise a red flag. A deposit protects you from being out of pocket on materials and shows the customer is committed to the project.
- Small jobs (under £500): Ask for full payment on completion, or 50% upfront if you need to order specific materials
- Medium jobs (£500–£5,000): A 20–30% deposit is standard. This should cover your material costs at a minimum
- Large jobs (over £5,000): Structure stage payments. For example, 30% deposit, 40% at a midway milestone (such as first fix completion), and 30% on completion
How to Present Deposits Professionally
Some tradespeople feel awkward asking for a deposit, but it is entirely normal and expected. Frame it as part of your standard process.
- Include the deposit amount and due date on your quote
- Explain that it covers material costs and secures the start date
- Send the deposit invoice as soon as the quote is accepted — do not wait for the customer to ask
- Do not start work until the deposit has cleared. This is a firm boundary that protects your business
How to Invoice Properly and Get Paid On Time
The way you invoice has a direct impact on how quickly you get paid. A scruffy, unclear invoice encourages delay. A professional, detailed invoice gets paid faster.
What Every Invoice Should Include
- Your business name, address, and contact details
- The customer's name and address
- A unique invoice number
- The date of the invoice and the payment due date
- A clear description of the work completed
- An itemised breakdown of costs (labour, materials, VAT if applicable)
- Your bank details or a payment link
- Your payment terms, including any late payment charges
Invoicing Best Practices
- Invoice immediately: Send your invoice the same day you complete the job. Every day you delay sending it is another day you wait to get paid
- Use digital invoicing: Email or text your invoice rather than posting it. The customer gets it instantly and can pay straight away
- Include a pay-now button: If your invoicing software supports it, add a direct payment link. Reducing the number of steps between reading and paying makes a huge difference
- Reference the quote: Link your invoice back to the original quote so the customer can see exactly what was agreed. Apps like QuoteGuru let you convert accepted quotes into invoices with a single tap
- Follow up before the due date: Send a polite reminder two days before payment is due. A simple "Just a reminder that invoice #1234 is due on Friday" catches the forgetful customers before they become late payers
How to Chase Late Payments Without Damaging the Relationship
Even with the best processes in place, some customers will pay late. The key is to have a clear escalation process that starts politely and gets progressively firmer.
Day 1 After Due Date
Send a friendly text or make a quick phone call. Keep it light: "Hi [Name], just following up on invoice #1234 which was due yesterday. Could you let me know when I can expect payment? Thanks." Most late payments are simply down to forgetfulness, and this gentle nudge resolves the majority of them.
Day 3–5
Send a formal email reminder. Attach a copy of the original invoice and reference your payment terms. Keep the tone professional but direct.
Day 14
Send a written letter (email and post) stating that the payment is now overdue and referencing the Late Payment of Commercial Debts (Interest) Act 1998. Under this legislation, you can charge 8% plus the Bank of England base rate as interest on overdue business-to-business invoices, plus a fixed sum of £40–£100 for debt recovery costs.
Day 30+
If the payment is still outstanding, you have several options.
- Small claims court: For amounts up to £10,000, you can file a claim through the Money Claims Online service. The fee is £35–£455 depending on the amount, and you do not need a solicitor
- Debt recovery service: A letter from a debt collection agency often prompts immediate payment. Most charge a percentage of the recovered amount
- Mediation: For disputes where the customer is questioning the work rather than simply not paying, mediation through a service like the CEDR can resolve things without going to court
Important: Keep written records of every communication about payment. Texts, emails, and letters all count as evidence if you need to take legal action. Never threaten a customer or use aggressive language — it can undermine your position if the case goes to court.
Accept More Payment Methods
One of the simplest ways to get paid faster is to make it easy for customers to pay you. If you only accept bank transfers, you are creating friction. Not everyone has their banking app set up, and some customers genuinely prefer to pay by card.
- Card payments: A card reader from SumUp or Square costs around £20–£40 and charges 1.69% per transaction. For a £500 job, that is £8.45 — a small price for getting paid on the spot
- Bank transfer: Include your sort code and account number on every invoice. Consider setting up a QR code that opens the payment screen automatically
- Online payment links: Services like Stripe or PayPal let you include a "Pay Now" button in your digital invoices
- Cash: Still acceptable for small jobs, but always provide a receipt and keep records for your tax return

Frequently Asked Questions
What payment terms should tradespeople set?
Most tradespeople should set payment terms of 7 to 14 days from invoice date. For domestic customers, payment on completion is common and preferred. For commercial clients and larger projects, 14-day terms are standard. Always state your payment terms clearly on your quote and invoice, and discuss them before starting any work.
How much deposit should a tradesperson ask for?
A deposit of 20 to 30 percent of the total job value is standard for most trades. For larger projects over £5,000, you can structure stage payments — for example, 30% upfront, 40% at a midway milestone, and the final 30% on completion. The deposit should cover your material costs at a minimum so you are never out of pocket.
Can tradespeople charge interest on late payments?
Yes. Under the Late Payment of Commercial Debts (Interest) Act 1998, businesses in England and Wales can charge interest of 8% plus the Bank of England base rate on overdue invoices from other businesses. You can also claim a fixed sum of £40–£100 as compensation for debt recovery costs depending on the invoice amount. This applies to business-to-business transactions, not domestic customers.
What is the best way to chase late payments as a tradesperson?
Start with a polite phone call or text the day after the payment is due. Follow up with a formal email reminder after three days. Send a written letter at the 14-day mark referencing the Late Payment of Commercial Debts Act. If the payment remains outstanding after 30 days, consider using the small claims court for amounts up to £10,000 or a debt recovery service. Always keep records of all communication.
How can digital invoicing help tradespeople get paid faster?
Digital invoicing speeds up payment by sending invoices instantly via email or text rather than waiting for post. Professional invoices with clear payment details and a pay-now button reduce friction. Apps like QuoteGuru let you convert accepted quotes into invoices with one tap, track which invoices are outstanding, and send automatic payment reminders — all of which reduce the average time from invoice to payment.
Conclusion
Cash flow problems do not fix themselves. But with the right payment terms, a proper deposit structure, professional invoicing, and a clear process for chasing late payments, you can dramatically reduce the time between completing a job and getting the money in your account.
Start by implementing the basics — invoice on the same day, take deposits on every job over £500, and offer card payments. Then invest in the tools that automate the process so you can spend your time doing what you do best: the actual work.
