We always measure what we do: the hours spent, the jobs repeated, the time we would like back. But there is another category, invisible to every calculation: what you never do. Not through neglect, but because there was never time. That work costs no time; it is revenue that never comes in. Unpaid invoices are a clear example, and automated payment chasing is a good place to start: each customer gets the right message at the right moment, until the money arrives.
No payback calculation can see them
An automation calculation always starts from the same place: how many times, how long, what the hour costs. A task that does not exist has none of those three numbers.
Its current cost is zero, so its gain is zero, so it appears nowhere. That is a structural flaw in the method, ours included, and it leaves out precisely the seams that can be very profitable.
Four jobs that get put off
There are four of them, and it is easy to recognise yourself in at least one:
- Chasing unpaid invoices, done whenever a spare moment turns up, never methodically.
- Monitoring tenders or grants, never started.
- Getting back in touch with former customers, put off for two years.
- Publishing regularly (articles, posts), abandoned after three weeks.
If the first one is on your list, the second half of this article is for you.
What they actually cost
A reminder that goes out on time, without relying on your memory, helps you get paid faster. A former client you call again already knows your work: winning them back takes less effort than convincing a stranger.
Tender monitoring puts you in front of contracts you would never have bid for. None of this is time saved: it is revenue.
An unpaid invoice also hurts twice: you have already done the job and often already paid the VAT (IVA) on it. And the older a debt gets, the less likely the money is to be recovered.
What overdue payments do to your cash flow
Every invoice you issue after the job is credit you give your customer until the due date; accountants call the total accounts receivable, and the more it grows, the longer you wait for income already earned. Following up overdue invoices on a fixed schedule can help make your income more predictable.
They are easier to automate than you would think
It may come as a surprise, but there is a logic to it. Automating existing processes means reproducing them faithfully, with their habits, exceptions and special cases piled up over years.
A task that does not exist has none of that: no prior process to respect, nobody to persuade to change their ways, no regression to fear. You start from a blank page. Debt collection is a case in point: if you chase payments whenever you remember, there is no existing process to copy.
How to spot yours
Ask yourself one question and write down the first answer that comes: what do you know you ought to be doing, and never do for lack of time?
Many owners answer within seconds. They know. It is not a diagnosis problem but a prioritisation problem, and the priority goes to whatever is urgent.
For the finance side, there is a more concrete test: count your overdue invoices. If you cannot give the figure without looking it up, you have found your first candidate.
Why the usual calculation falls short here
For an existing task we price it, compare it, and say yes or no against a threshold. For a task that does not exist there is nothing to compare: you have to estimate future revenue, which is judgement rather than arithmetic. We would rather say so than dress an intuition up as a table.
How automatic payment chasing works
Automatic payment chasing means a system watches your unpaid and overdue invoices and sends each customer, at each stage, the reminder you have prepared.
What matters is that it stops as soon as the client pays and alerts you when a debt needs your attention: one reminder sent to a client who has already paid can damage a business relationship. This guide is written for freelancers and small businesses based in Spain.
What you need before automating anything
- Your billing data in one place (amount, due date, payment status), so the system can follow each bill until it is paid.
- For business clients, the contact details of the people who sign off bills, often the accounts department.
- Your payment terms in writing from the quote, within the legal payment periods that apply in Spain.
Keep that data up to date, partial payments included, then set your credit control policy: when to remind, how firmly, when to escalate.
How to get customers to pay on time from the outset
Following up is the second line of defence. The first is reducing the risk before the first bill goes out:
- Simple credit checks: for a new company client, look at how long they have been trading and ask other suppliers about their experience.
- Credit limits: decide how many jobs you will take on before receiving anything, and ask for a deposit on larger jobs.
- A monthly statement: sending regular clients a summary of what is outstanding helps identify issues early.
- Different payment options: a transfer, a card link or a direct debit removes excuses; let customers choose.
Reviewing these practices alongside your reminders is a practical way to improve cash flow, and it gives you financial breathing room to focus on working for your clients rather than running after them.
Which tools can handle the follow-up?
Many invoicing programs and accounting software packages include the management of outstanding bills: they record what comes in and can send invoice reminders on a schedule you set, which can help you spend less time chasing invoices. If yours offers it, start there.
If not, simple tools connected to your list of invoices can handle the friendly stage, as our guide to how far no-code tools can take you explains. An AI assistant can also draft each message for you to check (see AI tools for freelancers).
A sequence before, on and after the due date
An effective sequence begins before the due date and raises the pressure step by step. This basic approach suits any type of client:
| Moment | What you send | Tone |
|---|---|---|
| A few days before the due date | An email with the amount, the date and how to pay | Informative |
| On the due date | A message with the invoice attached | Neutral |
| A few days later | A second reminder asking whether there are any problems | Friendly |
| If the invoice is still overdue | A call from you and, if appropriate, a payment plan | Personal |
| Final notice | A formal demand in writing | Formal |
The first three stages can go out automatically. The last two depend on the client's reply: you decide them case by case.
What each payment reminder should say
- The key details: number, amount owed and due date.
- What is needed to pay straight away: your bank account or a payment link.
- A contact person, in case of questions or mistakes.
Email, SMS or a messaging app?
Email is the usual channel: the invoice travels as an attachment and leaves a written record. An SMS or a messaging app suits a friendly reminder for customers who already write to you that way (see how to set up WhatsApp Business for free). Regardless of the channel, keep a copy of everything you send.
A firm tone that keeps the business relationship
A late payment is not always bad faith: sometimes the email ended up in spam, or the client is going through a difficult patch. The first reminders assume an oversight and make it easy to settle quickly; the wording gets firmer only if there is no reply, never with threats.
A plumber in Valencia does not write to the company that sends him jobs every month as he would to a private customer.
Manual chasing vs automation
By hand, reminders depend on your memory and your mood; automatic ones follow a schedule. In larger companies, a finance team handles this every week. As a freelancer, it competes with everything else on your list. Here is how the two compare:
- Timing: with manual chasing, messages go out when you find a moment; with a schedule, they go out on the planned day.
- Wording: a message written in a rush may sound too sharp; a prepared text stays professional and protects your client relationships.
- Follow-up: a system can match incoming payments with invoices and spot the overdue ones; by hand, it is easy to lose track.
- Judgement: a person can tell an oversight from a genuine difficulty and negotiate; software cannot.
Many freelancers struggle to ask for what they are owed, which is often why the follow-up never happens.
Automating the first steps removes the awkward part, and over a year the record of payments shows each client's payment patterns.
What UK guidance on late payments shows
Many English-language guides on this subject are written for UK businesses. UK law does not apply to a freelancer billing clients in Spain, but the official UK guidance is a useful example of how a government treats slow payers as a risk to small businesses.
- Interest and compensation: the GOV.UK guide on late commercial payments explains that a firm can claim statutory interest and debt recovery costs when another company pays late.
- Public reporting: under the payment practices reporting requirements, large UK companies publish reports on how they pay suppliers, so a supplier can check a customer before working with it and compare it with others in the market.
- A wider reform: the Department for Business and Trade ran a consultation, Late payments: tackling poor payment practices, on proposed legislation covering late, long and disputed payments and stronger powers for the Small Business Commissioner.
- Support for disputes: the Office of the Small Business Commissioner offers guidance and practical resources to smaller firms owed money by larger ones.
The UK guidance stresses that slow payment strains a supplier's finances and makes it harder to invest and grow. The main lesson travels well: agree clear terms, keep reminders polite and regular, and treat time chasing late payments as a cost to reduce. In Spain, check the payment periods and remedies that apply with your gestor or a lawyer.
From friendly messages to court
When the debt persists, claiming it starts to have legal consequences. From this point, nothing should go out automatically.
The formal demand, the last step before court
The out-of-court stage ends with a formal demand: a letter identifying the outstanding debt, the invoices it covers and your deadline for settling it, sent by a method that proves content and delivery, such as a burofax.
The monitorio procedure
If the formal demand gets no result, the courts remain. In Spain, monetary debts you can prove with documents (invoices, delivery notes, signed quotes) can be claimed through the procedimiento monitorio: the creditor asks the court to require the debtor to settle.
If the debtor neither pays nor objects, you can ask the court to enforce payment; if the debtor objects, the case becomes a trial. You can file the initial application yourself with those documents, but if the debtor objects, it is advisable to have a lawyer.
When to refer the debt to a lawyer
Ask a lawyer for advice when the debtor disputes the service, when the amount justifies a court claim, or when you are unsure of the steps. They will also check whether the debtor has assets: a judgment is worth little if there is nothing to collect.
Debt collection agencies also take on debt recovery for a commission; research and compare their fees and options before you sign.
What the system must not decide for you
Hand over the routine messages, not the decisions.
A tool cannot tell whether a late payment hides a difficult patch or a simple mistake, or whether your business is better off agreeing to instalments than opening a dispute. You stay in control of these:
- Negotiating a deferral with the client, in writing.
- Escalating from the friendly stage to the formal demand, then to court.
- Pausing the sequence if the client disputes the service, until it is resolved.
- Protecting the debtor's privacy: never publicise a debt or discuss it with third parties, as you could infringe their rights.

These jobs do not appear in our free diagnostic, deliberately: you cannot measure the cost of something you never do. The diagnostic prices a task you already do, with four questions and a result on screen in about two minutes.
If you recognise yourself in one of the four jobs, the next step is not a form but a short conversation about what that absence costs you. Write to us: this is the kind of subject best discussed out loud.
