The Missing Paragraph That Keeps Your Invoice Unpaid

You signed the contract, you did the work, everyone was happy.

You signed the contract, you did the work, everyone was happy. Then the invoice went out, and nothing happened. Three weeks later you sent a polite nudge, and two weeks after that a less polite one, and now you are eleven weeks into a thirty day payment term with no real idea what you are supposed to do next.

Here is the awkward part. You probably have a contract sitting in a folder that says exactly what you would deliver, by when, and to what standard. What it almost certainly does not say is what happens when the other side does not pay.

 

Most templates protect the buyer, not you

Pick up a free contract template and read it as though you were the client. It will usually tell you what the supplier must deliver, how the client can reject work, and how the client can walk away. That is not an accident. A great many templates floating around online started life as procurement documents, written by or for the party doing the buying.

When you sign one of those as the supplier, you have agreed to a set of obligations and received almost no protection in return. It feels like you have a contract, which is worse than knowing you do not.

 

Payment terms that actually do something

A payment clause needs three parts to be useful. It needs a date, so there is no argument about when late begins. It needs a consequence, which usually means interest on overdue amounts at a stated rate. And it needs a right to stop, so that you can suspend work without being in breach yourself while the invoice sits unpaid.

That last one does most of the work in practice. Interest is a useful threat but a slow remedy. The ability to down tools, politely and contractually, tends to get an invoice looked at the same afternoon.

The law is already on your side here, which surprises people. Under the European Union late payment rules, a business is entitled to interest on an overdue invoice at a minimum of eight percentage points above the European Central Bank reference rate, plus a flat forty euro contribution towards the cost of chasing it.

Business to business invoices are expected to be paid within sixty days unless both sides agreed something else.

Writing those terms into your contract does not create the entitlement. It makes it visible, which is what turns an awkward phone call into a short email pointing at a clause.

 

Scope creep is a payment problem wearing a different coat

The other common gap is change. A project is agreed, then a few small extras arrive, each one too minor to argue about, and by the end you have delivered a third more than you quoted for.

A change clause fixes this without any confrontation. It simply says that work outside the agreed scope is quoted separately and agreed in writing before it starts. You are not refusing anything. You are pointing at a document you both signed, which is much easier than having an opinion about whether a request is reasonable.

Most of our contract documents build these clauses in as standard, because they are the ones people notice are missing only while chasing an invoice that should have been paid weeks ago.

 

What if you have already signed one

If you are mid-contract with a document you now distrust, you are not stuck. Most commercial agreements can be varied by a short written amendment that both sides sign, and plenty of clients will agree to one without much fuss, particularly if you raise it alongside a renewal or a new piece of work rather than out of nowhere.

Keep the ask small. One paragraph adding payment terms and a change process is far more likely to be signed than a request to replace the whole contract, and it covers the two things that cause most of the trouble.

 

When it is already late

If an invoice has gone past its date, escalate in steps rather than jumping to the end. A short factual reminder, with the invoice attached again, clears most of them, because a surprising number of late payments are genuinely lost in an inbox.

If that goes nowhere, send a formal notice that names the clause, states the interest now accruing, and gives a date. This is the point where tone matters. Stay flat and procedural, because the moment it reads as emotional the conversation becomes about the relationship rather than the debt.

After that, suspend work if your contract allows it, and tell them you are doing so. Formal recovery is the last step and rarely needed, because almost everything settles once the other side realises the terms are real.

 

The clause nobody reads until they need it

Termination deserves a mention too. How does either side end this, how much notice is required, and what gets paid for work already done? A contract without that is fine right up until a relationship sours, at which point it becomes the only question anybody cares about.

 

Final Thoughts

A contract is not really about the work. The work is the easy part, and when things go well nobody opens the document at all. A contract earns its place on the bad days, when someone is late, or has changed their mind, or has quietly stopped replying.

If the one you are using does not say what happens on those days, it is not protecting you. It is just a description of a project with signatures at the bottom.
