There is a running joke in the trades that the hardest part of the job is not the work itself - it is getting paid for it. And like most jokes, it is funny because it is painfully true.
A 2025 survey by the Federation of Small Businesses found that 52% of small businesses in the UK experience late payments, with the average overdue invoice sitting unpaid for 28 days beyond its due date. For tradespeople, the numbers are even worse. Ask any plumber, electrician, or builder and they will tell you: chasing money is a constant, draining part of the job.
The good news is that most late payment problems are not about difficult customers. They are about systems - or the lack of them. Get your invoicing process right and you will spend less time chasing and more time earning.
Why late payments hit tradespeople hardest
When you work for a large company with a finance department, late payments are annoying but manageable. When you are a sole trader, a single unpaid invoice can mean you cannot buy materials for your next job, cannot pay your van finance, or cannot cover your own bills.
Unlike office-based businesses, tradespeople also front-load costs. You buy the materials, do the work, and then invoice. If the customer takes six weeks to pay, you have effectively given them an interest-free loan - funded from your own pocket.
The knock-on effects are real:
- Cash flow gaps force you to delay buying materials, which delays jobs, which delays more payments. It is a vicious cycle.
- Stress and distraction from chasing invoices takes you away from earning. Every hour spent on a "friendly reminder" email is an hour you are not on the tools.
- Relationship damage happens when you have to chase repeatedly. Nobody enjoys being the person who keeps asking for money, and nobody enjoys being asked.
Invoice on the day, not "when you get round to it"
This is the single biggest change you can make. The gap between finishing a job and sending the invoice is where money goes to die.
If you finish a bathroom refit on Friday and do not send the invoice until the following Wednesday, you have already lost five days. The customer has moved on mentally - the job is done, the urgency is gone, and your invoice joins a pile of things they will "sort out at the weekend."
The fix is simple: invoice the moment the job is complete. Ideally while you are still on site, or at worst in the van before you drive to the next job. If creating an invoice feels like a 20-minute task, your process is the problem - not your time management.
Tools like traidhand let you create and send a professional PDF invoice from your phone in under two minutes. Your customer's details, the job description, and your payment terms are already in the system - you are just confirming the final amount and hitting send.
Set clear payment terms before you start
One of the most common causes of late payment is vague expectations. If your quote does not mention payment terms, the customer has no deadline - and no deadline means no urgency.
Include your payment terms on every quote and invoice:
- Payment due within 7 or 14 days is standard for most trade work. 30 days is too generous for sole traders - you are not a building merchant.
- Deposit required for larger jobs. For anything over a few hundred pounds, asking for 25-50% upfront is completely reasonable and protects both parties.
- Stage payments for big projects. If you are doing a kitchen or bathroom refit, break the payment into stages - deposit, midpoint, and completion. This keeps your cash flow steady and gives the customer visibility.
Put these terms in writing before you start work. A verbal "yeah, I'll pay you when it's done" is worth nothing when you are three weeks into chasing.
Make it ridiculously easy to pay you
Every bit of friction between your invoice and their payment is a delay. If the customer has to ask for your bank details, that is a delay. If they have to write a cheque and post it, that is a delay. If they have to log into their banking app and type in a reference number, that is a delay.
Reduce the steps:
- Include your bank details on every invoice - sort code, account number, and a clear payment reference.
- Add a QR code that opens their banking app with the details pre-filled. Some invoicing tools generate these automatically.
- Offer card payments for smaller jobs. A card reader like SumUp or Zettle costs very little and lets the customer pay on site. For smaller jobs (under a few hundred pounds), many customers prefer to pay immediately if you make it easy.
The easier you make it to pay, the faster you get paid. It really is that straightforward.
Chase early, chase consistently
Most tradespeople wait too long before chasing. The invoice is due on Friday, it does not get paid, and by the following Thursday you are wondering whether to send a message. Another week passes. Now it is awkward.
Here is a simple chasing schedule that works:
- Day of invoice: Send the invoice with clear terms and a friendly note.
- Day before due date: A brief reminder - "Just a heads-up that invoice #123 is due tomorrow. Let me know if you have any questions."
- 3 days overdue: A polite follow-up - "Hi, just checking you received my invoice from [date]. The payment of [amount] is now a few days overdue."
- 7 days overdue: A firmer message - "I wanted to follow up on invoice #123 which is now a week overdue. Could you let me know when I can expect payment?"
- 14 days overdue: A final notice referencing your right to charge interest under the Late Payment of Commercial Debts Act.
The key is consistency. If customers know you always chase on day three, they will start paying on day one.
Set reminders so you do not forget. Better yet, use invoicing software that tracks overdue invoices and prompts you automatically. traidhand shows you exactly which invoices are outstanding and how overdue they are, so you never lose track.
Use deposits to protect yourself
Asking for a deposit is not being difficult - it is being professional. Deposits protect you from two things: customers who cancel after you have bought materials, and customers who are slow payers from the start.
A good rule of thumb:
- Jobs under £500: Full payment on completion is usually fine.
- Jobs £500 - £2,000: 30-50% deposit before starting, balance on completion.
- Jobs over £2,000: 25-30% deposit, stage payments at agreed milestones, final payment on completion.
Include your deposit requirements on your quote so there are no surprises. Most customers expect it and appreciate the professionalism.
Know your legal rights
UK law is on your side when it comes to late payments, but most tradespeople do not know it.
The Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to charge interest on overdue invoices at 8% above the Bank of England base rate, plus a fixed compensation fee of £40-£100 depending on the debt size. You do not need to have mentioned this in your terms - it is statutory.
You probably will not need to use it often, but mentioning it on your invoices ("We reserve the right to charge interest on overdue invoices in accordance with the Late Payment of Commercial Debts Act") is a powerful motivator. Customers take deadlines more seriously when there are consequences.
For persistent non-payers, the Small Claims Court handles debts up to £10,000 and costs as little as £35 to file a claim online. The threat of a County Court Judgment (CCJ) is often enough to prompt payment.
The bottom line
Getting paid on time is not about being aggressive or difficult. It is about having clear terms, professional invoices, and a consistent follow-up process. The tradespeople who get paid fastest are not the ones who do the best work (though that helps) - they are the ones who make it easy to pay them and follow up when payment is late.
Fix your invoicing process and you fix your cash flow. Fix your cash flow and everything else gets easier.
