Why won’t my customer pay up?
It’s helpful to understand why a customer isn’t paying your invoice. It could be:
- some customers are just badly organised, and may have genuinely misplaced your invoice
- your customer may be giving priority to other creditors, and deliberately holding back your invoices for payment
- your customer may be genuinely dissatisfied with the services or goods you’ve provided
- your customer simply may not have the money to pay you
- your customer may not have been aware of your payment terms until they read them your invoice.
All of these circumstances are unacceptable – cash flow is the lifeblood of any business, so you need to have a strategy for chasing customers for payment.
What can I do to make sure my customers don’t have reasons for not paying my invoices?
Prevention is better than cure – make sure that you’re doing all you can to stop late payment becoming an issue in the first place:
- Credit check your customers before you start working for them or selling to them, to see if you want to do business with them in the first place
- If you haven’t dealt with a customer before, consider asking them to pay a percentage of the expected bill up-front, e.g.to cover the cost of materials
- Make sure you have details of who and where to send the invoice to – sometimes these can be different from the person you’re dealing with already
- Ensure that your invoices have:
- All the information the customer needs, such as their purchase order number
- A clear statement of your payment terms, e.g. ‘Payment is due within 30 days of this invoice date. We understand and will exercise our statutory right to claim interest and compensation for debt recovery costs under the late payment legislation if we are not paid according to agreed credit terms.’
- Create a process to help ensure that your invoices get paid (see checklist below).

What should I do when my customers make excuses for not paying up?
Here are some of the common excuses for not paying and what you can do about them.
-
‘I’m sorry but we don’t seem to have received your invoice.’
By following our earlier advice about sending an invoice as a hard copy and also via email, the likelihood of the customer not getting it is minimal. If you get a receipt of delivery for your email you’ve proved that it was delivered! In any case, send it again and call straight away to check they’ve received it, and confirm when it will be paid.
-
'We would have paid your invoice but it doesn’t have your bank details on it.’
By not including all the information that’s required on your invoice or bill, you provide customers with the perfect excuse not to pay. Make sure your invoices include every piece of information that’s needed.
-
‘We can’t pay your invoice at the moment as our head of finance is on holiday. She’s the only person who can authorise it.’
Businesses nearly always have someone who’s authorised to sign-off payments in the absence of the person who normally does it, so it’s worth querying this. You could also ask for the email address of the responsible person so that you can drop them a line to let them know that payment is overdue and ask them to authorise it within a couple of days of their return. Politely point out your payment terms.
-
‘I’m sorry but the person you need to speak to isn’t here. Can I get them to ring you back?' ‘But I’ve already left several messages and they haven’t got back to me.’ ‘Sorry about that. I promise I’ll leave them a message.’
Promises, promises! Sounds like this creditor’s being given the run-around. If this happens to you, make a note of precisely when you called, and who you spoke to. Send details of this in a letter and/or email, clearly stating that you require payment by a specific date. Evidence of your attempts to get payment could be very useful if you decide to take legal action.
-
‘That person called again about their unpaid invoice.’ ‘Um … okay, we better pay that one now.’
Persistence often pays off. The more times you politely remind a customer you need paying, the more chance there is of them paying you next instead of another creditor who’s not chasing as often as you are!
-
‘I can’t pay you at the moment as I’m waiting for one of my own client’s to pay me.’
In these situations it can be worth expressing sympathy about their cash-flow problems, but reminding them that your arrangement (even if it’s just a verbal agreement) is with them, not with their client. Ask them how much they can pay now, and try to get them to agree to pay off the rest in stages. Again, the more persistent you are, the more likely they are to prioritise paying you.
How much interest can I charge a business for late payment?
The amount of interest you can charge a business for late payment for goods or services – known as ‘statutory interest’ – is governed by regulation. This amount is currently 8% plus the Bank of England base rate for business to business transactions.
So, for example if you’re owed £1,000, the annual statutory interest would be 1,000 x 0.085 (using the base rate of 0.5% at the time of writing) = £85.
To work out the daily interest divide £85 by 365 = 23p per day.
So the statutory interest on a payment that’s late by 60 days would be 60 x 23 = £13.80.
To find out more about charging interest on late payments, go to the Late commercial payments: charging interest and debt recovery section of GOV.UK.
Can I add additional charges to cover the time and effort involved in chasing a late payment?
As well as charging interest, you’re entitled to charge a late-paying business a fixed sum for the cost of recovering a commercial payment. At the time of writing this amount is:
- £40 for amounts up to £999.99
- £70 for amounts from £1,000 to £9,999.99
- £100 for amounts of £10,000 or more.
Can I get someone else to chase payments for me?
You could use the services of a specialist and reputable debt collecting agency. Some businesses prefer this, as it means that they don’t have to get involved personally in potentially awkward and confrontational conversations with customers they want to keep a relationship with.
You can use a debt collecting firm on a one-off or regular basis. Obviously, they will charge you for their services, and a one-off recovery is likely to be significantly more expensive than an on-going agreement.
Some agencies only deal with overdue payments, not disputed ones. For the latter, you may need to consult a solicitor who specialises in debt recovery. If you decide to use an agency or a solicitor, before you sign-up, check what their process is to make sure that they won’t just steam ahead with legal action before they’ve investigated the reason for non-payment, and consulted you about what action to take.
To find a debt collection agency, go to the website of the Credit Services Association.
To find a local solicitor who specialises in debt recovery, go to the Law Society’s solicitor database.
