Can I Automate Invoice Chasing? A UK Small Business Guide to Getting Paid on Time

Yes. Most UK small businesses can automate the bulk of invoice chasing, and many already have the tool to do it sitting unused in their accounting software. Xero and QuickBooks both have automatic payment reminders built in. Switch them on, write the wording properly, and you take most of the awkward chasing off your plate.

The harder part is everything those reminders do not cover. That is where a bit of extra automation, and knowing your rights, makes the difference.

Start with what you already pay for

If you use Xero, look for invoice reminders in the settings. If you use QuickBooks, look for automatic reminders on invoices. Both let you set when reminders go out relative to the due date and what they say.

A sensible starting pattern: a friendly note three days before the due date, a reminder on the day, a firmer one seven days after, and a final one at fourteen days. Write them in your own voice. Most people pay late because they forgot, not because they are refusing.

This costs nothing extra and takes an afternoon. I tell people to do this before paying anyone, me included.

Where built in reminders fall short

They treat every customer the same. Your best client of ten years gets the same message as someone who has ignored three invoices.

They stop at the reminder. Nobody gets told when an important invoice is now thirty days late. Nothing gets logged. Nobody picks up the phone.

They do not read replies. A customer writes back saying the invoice went to the wrong person, and that sits in an inbox while the reminders keep firing.

What a small custom automation adds

This is where a custom tool earns its money, and it is usually a small build. It can sort customers into groups so a long standing client gets a gentle personal nudge and a new one gets the standard sequence. It can read replies and flag them to you, so a dispute or a wrong address gets handled instead of chased. It can send you a short daily list of who is overdue, by how much, and what has been sent. And it can draft the firmer letter for you to check and send.

Notice the pattern. The tool drafts and flags. You decide when it gets firm. That matters, because one badly judged chaser can lose a customer worth far more than the invoice.

Your legal rights on late payment

For business to business invoices, the Late Payment of Commercial Debts (Interest) Act 1998 gives you the right to claim statutory interest at 8 percent above the Bank of England base rate. You can also claim a fixed sum towards recovery costs: £40 for debts under £1,000, £70 for debts from £1,000 to just under £10,000, and £100 for £10,000 or more.

This applies between businesses, not to consumers. And you do not have to use it. Many owners never do, because the relationship matters more. But mentioning it in a final reminder, calmly, often gets a long overdue invoice paid. If you go further than that, check the current rules on gov.uk or with an adviser first.

Getting the tone right

Automated chasing goes wrong when it sounds like a debt collector from day one. Keep the early messages warm and short. Make it easy to pay with a link in every email. Only get firm once a real person has decided it is time. And always give a way to reply to a human.

I wrote about keeping automated messages human in using AI without sounding like a robot, and the same rules apply here.

Is it worth paying for?

Work out what late payment costs you. Hours spent chasing each week, plus the cash you are waiting for. If it is an hour or two a week, the built in reminders are probably enough. If you are chasing dozens of invoices and it eats half a day, a small build pays back quickly. How much time AI saves a small business helps you do the sum, and what to automate first helps you check it is the right job.
