How To Chase Outstanding Invoices 


It’s annoying when clients don’t pay invoices on time. When you’ve done work they’re satisfied with and sent through an invoice, you expect payment to take care of itself. 

Unfortunately, sometimes it just doesn’t happen. This is just one of those realities that everyone has to face. Clients may have missed the invoice, lost it or forgotten it. 

Different people have different ways of chasing outstanding invoices. One of the toughest things about it is, how do you do it in a way that preserves your relationship with the client? You don’t want to be too aggressive, but you also want to be assertive enough so they know they need to pay the invoice now.  

This article is everything you need to know about chasing outstanding invoices so you can get paid quickly.  

Do late payers have an impact on cash flow? 

Unpaid invoices have a huge impact on business cash flow. Business costs don’t wait around for invoices to be paid, and if you don’t have money coming in then you have to rely on cash reserves to pay things like bills and wages, or purchase goods. 

Cash flow is extremely important in any business. Businesses have a range of costs, but invoices are the main income stream. Time spent chasing outstanding invoices is also a sunk cost, taking you away from your core business.  

Warning signs of missed payments 

When clients don’t pay invoices, it may be a sign of financial distress. This can mean invoices never get paid, which is the worst case scenario. However, there are signs to look out for that can signal this in advance.  

Warning signs include: 

  • Deviating from credit terms and conditions, when they haven’t in the past 
  • Becoming slower and slower to pay outstanding invoices 
  • Being slow to respond to messages, especially if they’ve always been good communicators 
  • Wanting to use cheques, or having cheques dishonoured 

In these instances, it may be worth considering your options. Ensure you have good terms and conditions in place. If you’re supplying goods to that client, you might want to refrain from actually handing over those goods until you’ve been paid. 

If you’re concerned that the client may be heading towards the point of not being able to pay an invoice, you might also consider refusing to work with them.   

Steps to making sure you get paid & if not, effectively chase invoices 

Navigating late invoices is about communicating well with your debtors. The primary goal is to get them paid in full, on time. Failing that, chasing outstanding invoices is all about getting them paid as soon as possible. 

This is a process you can follow to increase your likelihood of getting invoices paid on time. 

Setting up an invoice 

It all starts from before you even send the invoice. First and foremost, a good invoicing system is about clarity. It should be easy for the recipient to see who you are, how much they owe you, when it’s due and how to make payment.  

Set expectations early 

It helps to have clear expectations around prices with clients. If they haven’t paid an outstanding invoice, it may be because they’re questioning the amount you’re charging. 

If you anticipate charging interest on outstanding invoices, the client should know that too. Regardless of who’s at fault, they’re not likely to be pleased to be charged a surprise interest fee.  

Set realistic payment terms 

Similarly, you’ll want to set realistic payment terms that clients can satisfy. Most notably, this means allowing them a reasonable amount of time to pay the invoice. 

A gentle reminder 

Things can get a little awkward once due dates have been and gone. It’s standard to allow a grace period of a couple of days, but if it still hasn’t been paid then you can follow up with a gentle reminder. 

For example: 

Hi Imogen, hope you’re well. 

I’m just following up the invoice for last month, which was due two days ago. Just making sure you’ve received it and everything is in order. 

I’ve re-attached the invoice for reference. Let me know if there is anything I can do to help.  



Still not been paid? Communicate with the client 

If you still have outstanding invoices to be paid after another few days, it helps to try and call them. Emails can easily be missed, or flagged emails can get forgotten about.  

Following up with a phone call can also help the client to let you know if there’s anything else going on that you should know. 

Keep chasing the invoice  

If that doesn’t work and you STILL haven’t been paid, don’t give up unless you’re prepared to forgo the invoice. Going quiet will almost definitely result in it not being paid.  

8 Effective tips on chasing outstanding invoices 

There are other things you can do to ease the pain of chasing invoices. These deal with the frustration, time and money that it costs you to follow up with people who owe you money. 

Send a statement of accounts 

If you have one customer that has a number of missed invoices, you can summarise them in a statement of accounts. This shows all of their outstanding invoices in one place. 

It can be extremely frustrating to have someone that owes multiple payments pay only one of the outstanding invoices. A statement of accounts increases the chances of them paying all of their debts at once. 

Charge a late fee 

Late fees are perfectly acceptable, and can provide added impetus for the client to pay before incurring any more charges. 

As mentioned previously, it’s important to make your policy around charging them clear from the beginning. In New Zealand, companies can only charge a late payment fee if they tell clients about it before they enter into an agreement. This is one reason why having an agreed set of payment terms is beneficial. 

How much should you charge, and when? In the UK, government legislation allows small businesses to charge up to 8% interest, and this may be a helpful guide. 

When should you charge a late fee? Strictly speaking, a payment is late as soon as the due date has been and gone. Again, it helps to be clear in your payment terms about when a late fee will be charged. Going back to the UK, if there are no prior terms, a payment is considered late if it hasn’t been paid 30 days after the invoice was delivered. 

Automate invoice reminders 

One of the challenges with chasing outstanding invoices is that it takes you away from your core work. Most accounting software comes with the option to automate reminders for outstanding invoices.  

Reminders will go out at set times after an outstanding invoice was due to be paid, allowing you to focus on other things. This is particularly useful in small to medium-sized businesses where staff have more pressing tasks. 

Hire a debt collector 

Debt collectors can be extremely effective at getting invoices paid, however they often take at least 25% of the invoice in fees. On top of that, it’s likely to bring an end to your relationship with the client, so it should be a last resort. 

Hire a lawyer 

If even the debt collector didn’t work – or you chose not to go down that path – then you can take the client to court. Hiring a lawyer is expensive, which may ultimately end up wiping out the value of the invoice. And, even if you think you have a strong case, there’s no guarantee you will win.  

However, if the outstanding invoice is for a significant amount and you think it’s worth the time and energy that legal proceedings require, then going to court is an option.  

The exact nature of the court action will depend on a few different factors, such as the size and nature of the client’s business. It’s worth engaging a specialist lawyer who can expertly navigate the nuances of your particular case.
