Contracting: agreements, terms, and commitments

No writing, no proof

Most disputes between an entrepreneur and a client come not from bad faith but from vagueness. Who was supposed to deliver what, by when, for what price, with which revisions? Without a written record, everyone remembers in their own favor, and it's the party who wrote nothing who loses. A contract, a signed quote, or terms of sale aren't defensive paperwork: they're the rules of the game set before playing, which prevents 90% of conflicts and speeds up payment. The question isn't "am I at risk of a lawsuit," it's "do I want to be paid without a battle."

The documents that frame an activity

Depending on what you sell, several documents recur:

• The signed quote: for a one-off service, it's often the minimal contract — scope, price, deadline, deposit.
• Terms of sale (GTC): mandatory in B2C, strongly recommended in B2B; they set price, payment, delivery, withdrawal rights, warranties.
• Terms of use (ToU): for a website, app, or SaaS — usage rules and responsibilities.
• The service/engagement contract: for an ongoing relationship, more detailed than the quote (ownership, confidentiality, termination).
• The NDA (non-disclosure agreement): before sharing an idea or sensitive data.

The tools that keep you from starting from scratch

Starting from a blank page is the best way to forget an essential clause. Three families of tools:

Practical rule: take a solid template (Captain Contrat, official source), adapt it to your case, and have it reviewed by a lawyer at least once for your recurring documents (terms of sale, standard contract). You pay for a review, not a full draft — and then reuse it endlessly.

The danger of copy-pasted terms of sale

Copying a competitor's terms is tempting and risky: they sometimes refer to their structure, their warranties, their deadlines — not yours. Worse, they may themselves be poorly drafted. An ill-fitting clause is at best useless, at worst it turns against you (for example, a withdrawal clause missing where it's mandatory in distance B2C selling). Start from a template designed to be personalized, not from a blind copy-paste.

The clauses that truly protect

Beyond price and deadline, a few clauses make the difference the day things go wrong:

• Deposit and payment schedule: paying to start filters serious clients and secures cash flow.
• Late-payment penalties and retention-of-title clause: legal levers against unpaid invoices.
• Scope and amendments: defining what's included prevents unpaid "scope creep"; any addition goes through an amendment.
• Intellectual property: specify who owns the deliverables, especially in creative work (design, code, content).
• Confidentiality and termination: frame the exit as much as the entry.

AI to adapt, humans to validate

AI excels at personalizing a template: rephrasing a vague clause, translating a contract, checking that no obvious section is missing, explaining a clause to a client. It doesn't replace legal judgment: it ignores your real constraints and can invent law. The right reflex: generate or adapt with AI, then have a professional validate, once, the documents you'll reuse.

Key takeaways

Vagueness breeds disputes and unpaid invoices; writing sets the rules before play and speeds up payment. Depending on your activity, equip yourself with signed quotes, terms of sale/use, engagement contracts, and NDAs — starting from reliable templates (Captain Contrat, official sources) rather than copying a competitor. Polish the clauses that protect (deposit, penalties, scope, IP), adapt with AI but validate once with a lawyer. What remains is to give these documents force: getting them signed and archived, the subject of the next chapter.
