The contractual security infrastructure

Your payments are secure. So is the signature on your quotes.But to get paid, you still have to secure the contract.

The day a client contests, drags out payment or disappears, it isn't your quote that defends you. It's everything that happened afterwards: the extra added along the way, the fix, the approval promised out loud. And today, you hold all that in your head, in emails and scattered photos.

Definition

A Secure Contract is a service contract whose execution is administered and tracked end to end, from the first quote to the last signature. The contractual equivalent of secure payment: the relationship no longer rests on someone's word. Every step is recorded as it happens, and the file depends neither on your version nor the client's, because it cannot be rewritten after the fact.

The real danger

The risk isn't in the quote. It's in everything that comes after.

You sign, the job starts, the relationship is good. Then something unforeseen is added without being written down. A deadline slips for a reason that isn't yours. A fix is done without being dated. As long as all goes well, no one thinks about it.

The day it goes wrong, that's exactly what everything hinges on, and you have nothing to hand. Not the agreement for that extra work, not the proof of who caused the delay, not the date of the fix.

And you're not an isolated case.

What is a secure contract?

Securing a contract isn't adding a signature or taking out insurance. It's holding its execution, step by step, instead of leaving it to your memory and your emails.

A secure contract keeps four promises, from the start to the end of the job. They don't show on the days when all goes well. They decide everything the day it gets complicated.

01

Formalise

Commitments are expressed clearly, at the right moment. An accepted quote already counts as a contract; an unforeseen change is fixed with an amendment when it happens, not reconstructed six months later.

02

Trace

Every step that matters leaves its mark, in order: the visit, the agreement, the start, the fix, the handover. The thread of the contract is readable, not scattered across ten tools.

03

Keep

The useful documents stay together and accessible for the whole life of the contract. Nothing to dig out of an inbox: the file already exists, in one place.

04

Demonstrate

The day you have to explain what happened, the file is there: clear, dated as it went, and just as it was built, without having been rewritten in between. You don't look for proof, you open a file.

These four functions, no tool holds them together today. The signature stops at a moment. The contract template stops at the start. The spreadsheet proves nothing. A secure contract is all four, end to end.

The secure contract glossary

The same idea as secure payment

Your payments, you no longer wonder if they're safe. Your contracts, you do.

Fifteen years ago, taking a card online was frightening. Today, “secure payment” is enough to reassure you: you don't even think about it, because the transaction follows a proven method.

Your contract, though, you still hold by hand, each with their own version. Securing it means entrusting it to a method that dates every step as it happens and puts it out of reach: neither you nor your client can rewrite what happened. That's exactly what makes a file carry weight.

We do one thing no one else tools: hold, without taking sides, the file of what happened, so that it exists, intact, the day it counts.

The two fronts

A contract commits you on two fronts: that it holds, and that it pays.

Everything above protects the first front: the day someone contests, your file holds. But a contract that holds can still make you lose money. That's the second front, the one you feel at month's end: what the job actually leaves you.

Both play out in the same place, at the same time: in the contract, from the first quote to perfect completion. An hour missed in the pricing, extra work done without being recorded, a purchase tied to nothing, these are gaps in proof as much as gaps in margin.

Front 1

That it holds

The day a client contests, drags out payment or disappears, your file shows what happened, dated as it went. You don't defend a spoken word, you open a file.

Front 2

That it pays

While the job is running, you see what it leaves you: price sold, materials, hours at real cost. The margin is steered while you can still act, not at the accounts.

The same contract, held end to end, protects you when it's contested and shows you what it earns you. Securing a contract is both.

The client's side

“How do I know a provider is reliable?”

A client can't judge your work before seeing it. What he judges is what's in front of him before signing: the clarity of your quote, the tidiness of your exchanges, the order of your documents.

Working with secure contracts shows. A clean quote, a followed-up relationship, written commitments: the serious client recognises it, and chooses it. The rigour that protects you the day of a dispute is the same that wins you the signature the other days.

A homeowner and a tradesperson shake hands over a quote, in a calm room.

Your trade

A bricklayer and an electrician don't run the same risk.

General contracting answers for the trades it didn’t lay with its own hands. The electrician carries liability for years after sign-off. The joiner commits the material before being paid. The painter is judged by eye, on handover day.

The secure contract is the same foundation, adapted to each of these moments. It speaks your language, not ours.

What we get asked

Secure contract, in plain terms.

What is a secure contract?

A service contract whose execution is administered and tracked end to end, from the first quote to the last signature, following a structured process. It’s the equivalent, for the contract, of what “secure payment” became for the transaction: the assurance that the relationship follows a recognised method, rather than resting on someone’s word. It rests on four functions: formalise the commitments, trace the steps, keep the documents, and be able to demonstrate what happened.

How do I secure a service contract?

By stopping managing it by hand. In practice: get the quote-contract clearly accepted, fix each unforeseen change with an amendment the moment it arises, keep a dated record of the key steps (visit, start, fix, handover), and gather every document in one place. An accepted quote already counts as a contract; you still have to be able to demonstrate it. That’s the process, kept automatically as the job goes, that a secure contract brings.

How is it different from an electronic signature?

An electronic signature secures a moment: the point of commitment. Very useful, but the risk of a job arises afterwards, during execution, over time. A secure contract covers the whole cycle: what precedes the signature, what happens during the job, and the file that remains after. The signature is a step of the secure contract, not the other way round.

How do I prove a service was actually carried out?

Under French law, whoever claims payment for a service must be able to prove it was carried out. That proof is built during the job, not at the moment of dispute: an accepted quote, a signed amendment for the extra work, dated steps, a handover report. The problem is almost never bad faith; it’s that these documents are scattered or were never taken. A secure contract gathers them as it goes, in a single file.

Can a Probatoryx file be contested or tampered with?

The file builds itself, as the job goes: each step is recorded at its date and can no longer be modified afterwards, neither by you nor by your client. So it isn't your version against theirs, it's the sequence just as it happened. That's exactly what makes it hard to contest.

Does it have legal value?

A secure contract doesn't decide who's right in your place. What it changes is the weight of your file: because each step is recorded as it happens, without taking sides, and cannot be arranged after the fact, it's no longer your word against theirs, it's what happened, shown as it was. A dated, intact file always carries more weight than a memory and a few emails.

Do I need a written contract for every job?

A verbal agreement can bind you, but it's very hard to demonstrate. Above €1,500, the proof of agreement must in fact be written. And on a fixed-price contract, extra work is only owed if it was authorised in writing beforehand: a verbal agreement or silence is not enough. Writing isn't a formality of distrust, it's what protects both parties. A secure contract makes that writing natural, produced at the right moment, with no extra paperwork.

Does securing a contract also protect my margin?

Yes, that's the second front. A secure contract doesn't only hold the day of a dispute: because every hour, every purchase and every piece of extra work is tied to the right contract as it goes, you see what the job actually leaves you, while it's running. The same rigour that makes the file solid makes the margin accurate. A contract commits you on two fronts: that it holds, and that it pays.

Why can a signed job still lose money?

Because the margin is set at the quote, then eaten away during execution: time underestimated in pricing, a forgotten item, extra work done “because it had to be” but never recorded, so never paid. None of that shows in an end-of-job account, when it's already too late to act. Profitability plays out in the contract, as it goes: that's where it's protected.

Is it only for construction?

The secure contract applies to any service that unfolds over time. In practice, we tool it for the building trades: that’s where disputes cost the most and where the file makes the difference. If that’s your trade, everything here is built for you: your vocabulary, your documents, your cases.
