1.3Common contracts: sales, services, NDA
The essentials in 30 seconds
- Sale: conformity, price, transfer of ownership AND of risk (often distinct), warranties.
- Services: everything hinges on the precise deliverable; distinguish best-efforts from result obligations.
- NDA: quickly signed, binds for a long time — check scope, duration, exceptions, sanctions; never use an online template as is.
Threaded mini-case — Yacine juggles quotes, NDAs and general terms
Yacine's digital SME in Algiers sells refurbished hardware, builds websites for clients and talks to a partner who asks him to sign an NDA before speaking. For sales, he distinguishes ownership from risk during transport; for services, he describes the deliverable instead of a vague “showcase site” and clarifies whether he owes best efforts or a result; for the NDA, he checks what is covered and for how long before disclosing anything.
Following cases 1.1–1.2 — Yacine applies each precaution to the day's business.
1. Sales and services
The sales contract: transfer of ownership of goods in exchange for a price. Watch conformity, the price, the transfer of ownership AND of risk (often distinct — key in case of transport) and warranties.
The services contract: everything hinges on the precise definition of the deliverable. Distinguish a best-efforts obligation (working diligently without guaranteeing the outcome) from a result obligation (guaranteed outcome) — decisive in case of dispute.
2. The NDA and the others
The NDA (non-disclosure agreement): check the scope of what is confidential, the duration, the exceptions and the sanctions before talking. Quickly signed, but it binds you for a long time.
Many other contracts exist (lease, distribution, franchise, agency…). Two pieces of advice: beware of online templates used as is, and always adapt to the specific case and local law.
🔎 Concrete example — 🔎 Practical example — Best efforts or result?
A choice of words that shifts the risk.
Best-EFFORTS obligation: “use reasonable efforts to” (consultant) → negligence must be proven.
RESULT obligation: “guarantee that” (deliver a working item) → the mere absence of result is enough.
→ the wording of the deliverable changes everything in case of dispute.Result: you know what to check depending on the type of contract.
Reflex: adapt to the specific case, have high-stakes contracts reviewed.
Section vocabulary
- Sales contract
- A contract by which a seller transfers ownership of goods to a buyer for a price.
Simple example: Yacine sells a batch of refurbished PCs to a school.
What it is not: a website development service.
Reflex: sale = goods for a price; check conformity and transfers.
- Transfer of risk
- The moment from which the buyer bears the loss of or damage to the goods (not always the same as the transfer of ownership).
Simple example: Yacine specifies who bears breakage during transport to the client.
What it is not: the transfer of ownership itself.
Reflex: with transport, write down who bears what and when.
- Best-efforts / result obligation
- Best efforts: diligently applying know-how without guaranteeing the outcome; result: guaranteeing a precise outcome.
Simple example: Yacine “uses best efforts to improve search ranking” (best efforts) but “guarantees an accessible website” (result).
What it is not: the price or the duration of the contract.
Reflex: spot the verbs: guarantee, deliver, use best efforts to.
- NDA
- A contract undertaking not to disclose exchanged confidential information.
Simple example: Yacine signs an NDA before showing his demo to the partner.
What it is not: a mere handshake with no written commitment.
Reflex: disclose nothing before reading scope, duration and sanctions.
- Services contract
- A contract by which a provider performs work for payment; the precise definition is decisive.
Simple example: Yacine's contract lists pages, features and acceptance criteria.
What it is not: a vague “website redesign” with no described deliverable.
Reflex: no vague services: deliverable, deadlines, criteria in writing.
In practice — In practice — Checking the essentials by contract type
- Sale: check the conformity of the goods, the price, the moment of the transfer of ownership AND of risk, and the warranties.
- Services: require a precise definition of the deliverable, time limits and criteria; clarify whether it is a best-efforts or a result obligation.
- NDA: check what is covered, the duration, the exceptions and the consequences of a breach BEFORE disclosing or signing.
- Never reuse an online template as is: adapt it to the specific case and your local law, and have high-stakes contracts reviewed.
Ready-to-use script — framing services before signing (30 s)
“To avoid any misunderstanding: here is the exact deliverable, the deadlines and the acceptance criteria — and I'll specify where I commit best efforts and where I guarantee a result. Shall we put it in writing before signing?”
Say to the client: put the deliverable and the obligation regime in black and white.
Copy-paste template — check by contract type
SALE (conformity / price / ownership AND risk / warranties): _______________
SERVICES (precise deliverable / deadlines / criteria / best efforts or result): _______________
NDA (scope / duration / exceptions / sanctions): _______________
TEMPLATE ADAPTED TO THE CASE AND COUNTRY (yes / to have reviewed): _______________Hardware sale
Specify condition, conformity, price, who transports and who bears the risks, and warranties — especially for refurbished goods.
SME Algiers
Yacine writes his quotes and general terms consistently with his local practices (delivery, payment, contract language) and has them reviewed before regular use.
Intellectual services
Add ownership of creations, included revisions, acceptance criteria: that is where most disagreements arise.
Mutual NDA
When both sides disclose: provide reciprocity (scope and duration on both sides) instead of a one-way NDA.
✓ Best practices
- Sale: distinguish the transfer of ownership from the transfer of risk.
- Services: clarify whether it is a best-efforts or a result obligation.
- NDA: check scope, duration, exceptions and sanctions before talking.
✗ Common pitfalls
- Confusing the transfer of ownership with the transfer of risk.
- Leaving the deliverable of a services contract vague.
- Reusing an online template as is (often unsuitable, sometimes void outside its context).
Key takeaways
- Sale: watch conformity, the price, the TRANSFER of ownership and of RISK (often distinct), and warranties.
- Services: everything hinges on the precise definition of the deliverable; distinguish a best-EFFORTS obligation (diligence) from a RESULT obligation (guaranteed outcome).
- NDA: a quickly signed contract that binds you for a long time; check scope, duration, exceptions and sanctions before talking.
- Avoid online templates used as is (often unsuitable/void outside their context); adapt to the specific case and local law.

Frequently asked questions
Why is the distinction between “best-efforts” and “result” obligations so important?
Because it determines what must be proven if something goes wrong, and therefore who wins a dispute. Under a best-efforts obligation, the debtor commits to using all reasonable means without guaranteeing the outcome (a doctor treats according to best practice without guaranteeing recovery; a consultant works diligently). Under a result obligation, the debtor guarantees a precise outcome (the carrier delivers the parcel; the seller supplies a working item). The consequence lies in the burden of proof: if the obligation is one of result and the result is missing, the client only needs to establish that fact — it is up to the debtor to exonerate itself. If it is a best-efforts obligation, failure is not enough: the client must prove negligence, which is far harder. Hence a major negotiation issue: how a service is described (“perform”, “guarantee”, “use reasonable efforts to”) moves the contract from one regime to the other, and with it the risk.
Can I rely on a contract template found on the Internet?
A template is useful to understand the structure of a contract. Using it as is for a high-stakes transaction is a false economy. The template almost always comes from another legal context: clauses may be unsuitable, unenforceable, or even void in your country, or it may omit mandatory statements required where you are. It is also generic whereas your situation is specific (it leaves grey areas exactly where disputes arise). And without legal knowledge, you cannot assess the scope of technical clauses. The graduated approach by stakes: for routine low-risk transactions, a simple contract, reviewed and customised, may be enough; for major contracts (high amounts, duration, international aspects, intellectual property), having a professional draft or review it is almost always cost-effective. A smart route: have a custom template drawn up for your recurring transactions.
