Unpaid invoices rarely appear out of nowhere.
There are almost always warning signs beforehand.
And although no business is completely immune, the reality is that many non-payment situations could be avoided with small adjustments to the way a business operates.
At CONESA LEGAL, we see a very clear pattern: by the time legal action becomes necessary, the underlying issue actually often began months earlier with what at the time seemed like minor commercial, administrative or contractual decisions.
These are some practical steps that can significantly reduce risk.

1. THE FIRST FILTER: CHOOSING THE RIGHT CLIENT (AND NOT FORGETTING PAST EXPERIENCE)
Many payment issues begin even before the work is accepted.
Choosing the right client remains one of the most effective preventative measures. This is not about distrusting everyone, but about applying sound commercial judgement, particularly where the engagement is significant, i.e.:
- confirming who the client actually is,
- reviewing basic company information,
- assessing whether the scale of the work makes sense given their structure,
- and paying attention to their behaviour during negotiations.
Problems often reveal themselves: excessive urgency, reluctance to agree to terms, resistance to advance payments or constant attempts to change what was agreed.
But something else is perhaps even more important: maintaining an internal record of past experience.
Many businesses end up working again with clients who previously caused payment issues simply because that history was not flagged internally.
This is why it is essential to:
- maintain an internal client record system,
- keep a record of payment issues,
- and ensure communication between commercial, finance and management teams.
A client who has caused problems does not necessarily need to be ruled out permanently… but they should certainly be approached with greater caution before further work is accepted.
2. CLEAR CONTRACTS, PROPERLY DRAFTED… AND PROPERLY AGREED TO
A contract will not prevent every unpaid invoice, but it will prevent many disputes later on.
A well-drafted contract should clearly set out:
- the services being provided,
- the fees,
- when payment is due,
- what happens in the event of non-payment,
- and when services may be suspended.
Drafting matters. Vague clauses frequently become real problems when the first late payment arises.
That said, one of the most common mistakes is not the absence of a contract, but something more straightforward: having terms that were never properly agreed to.
Simply sending a document by email does not mean there is a binding agreement.
You should be able to demonstrate that the client accepted the terms, for example through:
- a signed agreement,
- clear written acceptance,
- or payment of an initial retainer in accordance with the agreed terms.
If acceptance cannot be evidenced, the contract becomes far less useful when you need to recover the debt.
3. INVOICING CORRECTLY AND PROMPTLY
It may sound obvious, but many disputes start here.
Incomplete, delayed or unclear invoices create perfect excuses for late payment.
Some basic good practice includes:
- issuing invoices promptly once the work is completed,
- clearly describing the services provided,
- including clear payment terms,
- and avoiding letting invoices build up over several months.
The longer an invoice remains unpaid, the harder it usually becomes to recover.
4. PAYING ATTENTION TO WARNING SIGNS (AND REGULARLY REVIEWING OUTSTANDING INVOICES)
There are almost always signs when clients begin to experience financial pressure.
Comments such as:
"This month is a bit tight for us",
"We’re waiting for payment for a major transaction",
"I’ll pay as soon as some funds come in",
do not necessarily indicate bad faith. But they are not insignificant.
This is where something critical comes into play: regular monitoring of unpaid invoices.
Debt recovery is not a one-off action; it is an ongoing process. Regularly reviewing outstanding balances allows businesses to act quickly and prevents smaller amounts from turning into difficult debts.
The earlier a problem is identified, the more options there are to resolve it with minimal conflict.
It is also worth remembering that taking control of a debt as soon as possible is in everyone's interest. You don't want to take the losses, and your client is unlikely to want to fall into a debt spiral that may later become difficult to get out of.
Sometimes the commercial relationship may need to end. But, in other cases, you may be able to offer alternative, more cost-effective services to your client, or a structured payment plan that helps them regularise their position.
In any event, solutions usually only start to emerge once the issue is openly addressed.
5. PAYMENT REMINDERS ARE MORE EFFECTIVE THAN MANY BUSINESSES EXPECT
In many cases, invoices remain unpaid simply because they have been overlooked.
And this happens more often than many businesses assume.
A polite and professional reminder will often resolve a large proportion of late payments without ruffling any feathers. In fact, clients frequently appreciate the reminder where the delay was unintentional.
A common mistake is waiting too long before following up.
Early follow-up demonstrates professionalism and reinforces that timely payment is a normal part of the commercial relationship.
An example of a clear internal process might include:
- a reminder just before the due date,
- immediate follow-up after a missed payment,
- a formal demand if payment is still not made,
- external legal involvement where necessary.
6. MAKING PAYMENT EASY: DIRECT DEBIT IS NOW STANDARD PRACTICE
Today, almost everything operates on direct debit.
Netflix, Amazon Prime, digital platforms, gym memberships, professional software… businesses and consumers alike are used to services continuing while payment is automatic, and stopping when payment stops.
Clients already understand this model.
For that reason, where appropriate, direct debit can significantly reduce the risk of non-payment.
Can a client ask for flexibility? Of course.
The real question is whether agreeing to that flexibility makes commercial sense.
Sometimes it does, for client retention or strategic reasons. But often it doesn't. Flexibility should be a conscious commercial decision, not a knee-jerk reaction.
7. THE IMPORTANCE OF AMICABLE DEBT RECOVERY
Not every unpaid invoice requires immediate court action.
Many debts can be recovered through a properly handled, out-of-court recovery process led by lawyers. Professional involvement alone often affects a debtor’s attitude.
A properly structured legal demand:
- demonstrates seriousness,
- establishes a clear legal position,
- opens the door to realistic payment arrangements,
- and can avoid unnecessary litigation costs.
Don't wait indefinitely for a client to pay “when they can”.
The longer recovery is delayed:
- the higher the insolvency risk,
- the harder it may be to identify recoverable assets,
- and limitation deadlines may begin to approach.
8. PREVENTION ALSO INVOLVES SEEKING OUT ADVICE
Many businesses only seek legal advice once a problem has already arisen. However, reviewing contracts, invoicing terms and credit control procedures from a preventative, legal perspective can significantly reduce late payments.
Avoiding payment issues depends not only on the type of client, but also on how the commercial relationship is legally structured.
IN SUMMARY
Avoiding unpaid invoices is not about one single measure, but about a combination of commercial, contractual and organisational decisions.
Choosing clients carefully, properly documenting agreements, regularly reviewing outstanding invoices and acting promptly can significantly reduce exposure.
And where non-payment does arise, obtaining legal advice early can make the difference between successful recovery and having to write the debt off.
