Winning a new customer is exciting.

Getting them to pay on time? That's often the harder part.

Late payments remain one of the biggest challenges facing small businesses in the UK. Government figures show more than half of SMEs experience late payments, while the Federation of Small Businesses estimates they cost the average small business around £22,000 a year and contribute to around 50,000 business closures every year.

The frustrating part is that many late payments aren't caused by customers refusing to pay. They're caused by small delays, unclear processes and invoices that slip to the bottom of someone's inbox.

The good news? A few simple changes can make a big difference.

Don't let your work go cold

One of the biggest mistakes business owners make is waiting to send the invoice.

Maybe you're busy. Maybe you only invoice once a month. Maybe admin gets pushed to Friday afternoon.

But every day you wait is another day before the payment clock even starts.

There's another reason to invoice quickly. Your work is still fresh in your customer's mind. They're more likely to remember the value you've delivered than they are three weeks later.

Treat invoicing as the final step of the job, not the first step of your admin.

Have the awkward conversation before you start

Talking about money before you've even started work can feel uncomfortable.

But it's far less awkward than chasing an overdue invoice six weeks later.

Before you begin, agree exactly how much you'll charge, when payment is due, how you'll invoice and who'll approve it.

That five-minute conversation can save hours of emails and phone calls later.

Make paying you effortless

Think about the last time you abandoned an online purchase because checkout took too long.

Your customers aren't much different.

If they have to search for your bank details, ask for another copy of the invoice or work out how to pay you, there's a good chance they'll come back to it later.

And later often turns into next week.

Include clear payment instructions, offer digital payment options where possible and make it obvious when payment is due.

The easier it is to pay you, the faster you're likely to get paid.

Don't wait until the invoice is overdue

Most people only chase an invoice once it's already late.

By then, your customer may have forgotten about it altogether.

Instead, send a friendly reminder a couple of days before it's due.

A simple message saying, "Just a reminder this invoice is due on Friday" often works better than an email asking why it hasn't been paid.

You're helping your customer stay organised, not accusing them of being late.

Stop thinking of invoices as admin

This is where many businesses get it wrong.

An invoice isn't just paperwork. It's part of your customer experience.

A professional invoice that arrives promptly, is easy to understand and simple to pay leaves a much better impression than one that's missing information or arrives weeks after the work is finished.

Getting paid starts long before the payment date.

Ask for money upfront when it makes sense

If you're taking on a large project, don't be afraid to ask for a deposit or agree stage payments.

This isn't about mistrusting your customer.

It's about protecting your cash flow and making sure both sides are committed.

For many industries, staged payments are now standard practice rather than the exception.

Automate the chasing

No one starts a business because they enjoy sending payment reminders.

If you're relying on memory or spreadsheets, it's easy for invoices to slip through the cracks.

Using accounting software to send invoices and automatic reminders means customers get consistent follow-ups without you having to think about it.

Sometimes the difference between getting paid on day 30 instead of day 45 is simply remembering to send the reminder.

Know when it's time to say no

Most late payments are genuine oversights.

Some aren't.

If a customer regularly ignores agreed payment terms or repeatedly pays late without explanation, it's worth asking whether they're the right customer for your business.

One unreliable client can create cash flow problems that affect everything from paying suppliers to investing in growth.

Sometimes protecting your business means walking away.
