Main Types of B2B Commercial Contracts and Their Legal Categories

In French business law, correctly qualifying a commercial contract is far more than an academic exercise: it determines the applicable legal regime, the parties' obligations, enforceable guarantees and available remedies in the event of dispute. Yet many companies sign documents without fully understanding their precise legal nature. This article provides a comprehensive mapping of the principal types of B2B commercial contracts, classified by legal categories, with essential points of caution for 2026.

Contracts for the Sale and Supply of Goods

Commercial sale is the archetypal B2B contract. Governed by the French Code of Commerce and Civil Code (articles 1582 et seq.), it transfers ownership of a good in exchange for a price. However, its application in a professional context generates several variants with distinct legal regimes.

Standard Commercial Sales Contract

In a B2B relationship, sales are governed by articles L. 441-1 to L. 441-16 of the Code of Commerce, which strictly regulate payment terms (30 days as a general rule, 60 calendar days maximum from the date of invoice issue, in accordance with the LME Act of 4 August 2008). Any clause derogating from these ceilings is deemed unwritten. Late payment penalties are mandatory, with the minimum rate set at three times the statutory interest rate.

B2B sales differ from consumer sales in the absence of consumer protection provisions (no statutory withdrawal right, no statutory conformity guarantee under the Consumer Code). However, the guarantee against hidden defects (art. 1641 Civ. Code) remains fully applicable.

Supply and Procurement Contracts

The framework supply contract organises successive deliveries over a determined or indeterminate period. It establishes general conditions (price, quality, delivery times) and references purchase orders for each transaction. This structure is widespread in industrial relationships and large-scale distribution. The AI-powered contract generator from Certyneo enables you to structure these documents by automatically integrating mandatory clauses derived from French commercial law.

Article L. 442-1 of the Code of Commerce (stemming from Ordinance No. 2019-359 of 24 April 2019) prohibits restrictive competition practices in these contracts, notably significant imbalance between the parties' rights and obligations.

Service Provision Contracts

Service provision contracts represent the majority of commitments in the tertiary, technology and consulting sectors. Their regime depends on the nature of the obligation undertaken: best-efforts obligation or obligation to achieve a specific result.

Intellectual Services Provision Contracts

Consulting, auditing, training, software development, market research: these contracts are often qualified as enterprise contracts (or work service contracts) within the meaning of article 1710 of the Civil Code. The distinction between best-efforts and result-based obligations has major consequences for the burden of proof in the event of dispute.

Regarding intellectual property, service provision contracts must explicitly provide for the assignment of copyright over deliverables (art. L. 131-1 et seq. of the Intellectual Property Code); otherwise, rights remain in the service provider's assets, even after full payment.

Subcontracting Contracts

Subcontracting is governed by Act No. 75-1334 of 31 December 1975. It creates a three-party relationship (principal contractor, main contractor, subcontractor) with specific obligations: approval of the subcontractor by the principal contractor, direct payment action by the subcontractor against the principal contractor, mandatory payment guarantee. This protective regime is of public policy: it cannot be derogated from by contract. To understand how the legal value of electronic signature applies to these documents, it is necessary to distinguish the levels of eIDAS signature required according to the criticality of the contract.

SOW (Statement of Work) in IT Contracts

In complex technology projects, the Statement of Work is often annexed to the framework contract. It defines the precise scope of the mission, deliverables, milestones and acceptance criteria. Our dedicated guide on the SOW: template, clauses and electronic signature outlines best practices for securing these documents in a B2B environment.

Distribution and Commercial Representation Contracts

The commercialisation of products or services through intermediaries gives rise to specific contracts, whose qualification has important effects on taxation, employment law and termination indemnities.

Exclusive and Selective Distribution Contracts

Exclusive distribution reserves to a distributor a defined territory or customer base. It is governed by the European Block Exemption Regulation No. 2022/720 of 10 May 2022 (the "VBER"), which replaced Regulation 330/2010. This text authorises vertical restrictions subject to conditions, provided that each party's market share does not exceed 30%.

Selective distribution, for its part, selects resellers according to qualitative criteria. It is lawful if the criteria are objective, uniformly applied and non-discriminatory (Metro doctrine, CJEU).

Commercial Agent Contract

A commercial agent is an independent representative who negotiates and concludes contracts on behalf of and in the account of the principal. Its status is protected by Directive 86/653/EEC and articles L. 134-1 to L. 134-17 of the Code of Commerce. In the event of termination without serious cause, the agent is entitled to a compensation indemnity generally corresponding to two years of gross commissions. This protection is of public policy.

Caution: requalification of an "independent contractor contract" as a commercial agent contract is frequent in case law and exposes the principal to substantial indemnities.

Franchise Contracts

Franchise combines a know-how and brand licence contract with a supply contract. It is subject to the Precontractual Information Document (DIP) provided for by the Doubin Act (Act No. 89-1008 of 31 December 1989), to be provided at least 20 days before signature. The absence of a DIP may result in contract nullity.

Inter-Company Partnership and Collaboration Contracts

Strategic alliances between companies generate hybrid contracts that combine several legal mechanisms.

Commercial Partnership Contracts (co-development, contractual JV)

Contractual joint ventures (without the creation of a separate legal entity) are based on a partnership contract that allocates contributions, risks, revenues and governance of the joint project. Drafting these contracts requires particular attention to confidentiality clauses (NDA), shared intellectual property, conflict resolution and exit provisions.

For these strategic high-stakes contracts, qualified electronic signature compliant with the eIDAS regulation offers the maximum level of legal security, equivalent to handwritten signature before a notary.

Collaboration and Co-Contracting Contracts

Distinct from subcontracting, the co-contracting agreement unites multiple enterprises that jointly respond to a call for tender, each executing its portion without any subordination relationship. A common representative ensures coordination and liability towards the client. This structure is common in public procurement and major infrastructure projects.

B2B Financial and Guarantee Contracts

Commercial relationships are often accompanied by financial instruments and securities that form a contractual category in their own right.

Inter-Company Loan Contracts

Since the Macron Act of 6 August 2015, enterprises may grant loans to one another subject to strict conditions (maximum duration of 2 years, borrower linked economically to the lender, statutory auditor report, etc.). This mechanism, codified in articles L. 511-6 and L. 511-7 of the Monetary and Financial Code, remains regulated to prevent circumventing banking monopoly.

Autonomous Guarantees and Comfort Letters

An autonomous guarantee (or demand guarantee) is a personal security independent of the underlying contract. Governed by articles 2321 et seq. of the Civil Code (2021 security reform, Ordinance No. 2021-1192 of 15 September 2021), it carries immediate enforceability. A comfort letter, by contrast, is an undertaking by the parent company to the creditor of a subsidiary, whose legal scope varies according to its precise wording.

For all these documents, the downloadable contract templates available on Certyneo integrate clauses updated in accordance with the 2021 security reform and the latest case law developments.

Legal Framework Applicable to B2B Commercial Contracts

The validity and enforceability of B2B commercial contracts rest on a dense body of legislation, whose mastery is essential to secure business commitments.

Civil Code — General Law of Contracts

Since the reform of contract law (Ordinance No. 2016-131 of 10 February 2016, ratified by Act No. 2018-287 of 20 April 2018), articles 1101 to 1386-1 of the Civil Code form the common foundation of any contract. Article 1128 sets out the conditions for validity (consent, capacity, lawful content). Article 1171 deems unwritten any clause creating a significant imbalance in adhesion contracts. Article 1195 introduces the theory of unforeseen circumstances, permitting renegotiation if circumstances change unpredictably.

Electronic Signature — Articles 1366 and 1367 of the Civil Code

Article 1366 recognises electronic writing as having the same probative force as paper writing, provided the author is identified and the document's integrity is ensured. Article 1367 assimilates electronic signature to handwritten signature when it consists of a reliable process of identification guaranteeing its link with the act. These provisions interact with the eIDAS Regulation No. 910/2014 of 23 July 2014, which distinguishes three levels of signature: simple (SES), advanced (AES) and qualified (QES). Only qualified signature benefits from an irrebuttable legal presumption of reliability throughout the European Union. The eIDAS 2.0 Regulation (EU Regulation 2024/1183), progressively applicable from 2024, strengthens requirements for digital identity with the European Digital Identity Wallet (EUDIW).

Data Protection — GDPR No. 2016/679

Any commercial contract involving the processing of personal data (contact details of signatories, HR data, customer information) must comply with the GDPR. Data processing clauses (DPA — Data Processing Agreement) are mandatory when one party acts as a processor within the meaning of article 28 of the GDPR. The CNIL recommends integrating these clauses directly into commercial contracts rather than cross-referencing separate annexes.

Electronic Invoicing — 2026-2027 Reform

The mandatory electronic invoicing reform (Finance Act 2020, Decree No. 2022-1299 of 7 October 2022, timetable revised by Order of 15 October 2023) requires VAT-taxable enterprises to issue and receive invoices via approved platforms (PDP) from 1 September 2026 for large enterprises and mid-cap companies. This obligation directly affects B2B sales and service provision contracts, whose invoicing conditions must be revised accordingly.

Restrictive Competition Practices

Article L. 442-1 of the Code of Commerce (stemming from Ordinance No. 2019-359) penalises significant imbalance, abrupt termination of established commercial relationships (L. 442-1, II) and discriminatory practices. Commercial courts apply these provisions with increasing strictness, civil fines potentially reaching 5 million euros or three times the amount of unduly obtained benefits.

Concrete Usage Scenarios

A SaaS Software Publisher Managing Several Hundred B2B Contracts Annually

A SaaS publisher offering HR management solutions to SMEs and mid-cap companies simultaneously manages subscription contracts, SLAs, GDPR DPAs and price amendment agreements. Without a structured contractual workflow, validation cycles average 12 to 18 working days per contract, according to sector benchmarks published by APOGE. By deploying an advanced electronic signature solution integrated with its CRM, this publisher reduces the signature timeframe to fewer than 48 hours in 80% of cases, lowers its documentary error rate by 35% and reduces printing and paper archiving costs by nearly 90%. Traceability of exchanges (qualified timestamping, audit trail) strengthens its position in the event of contractual disputes.

An Industrial Distribution Group Restructuring Its Supplier Contracts

A distribution company specialising in industrial equipment, working with 400 European suppliers, must update all its framework contracts to integrate the new requirements of VBER Regulation 2022/720 on exclusive distribution and B2B electronic invoicing obligations effective from September 2026. By centralising contract management on a single platform, it reduces the timeframe for updating its document database by 60%, automates reminders at renewal and secures electronic archiving for the legal duration of 10 years (art. L. 123-22 C. com.). Integration of an alert system for expiry dates prevents unwanted tacit renewals, a recurring source of disputes in the sector.

A Strategy Consulting Firm Managing Multi-Party Missions

A consulting firm working on transformation projects involving multiple co-contractors must simultaneously secure client contracts, co-contracting agreements, NDAs and deliverable rights assignment contracts. The multiplication of stakeholders (CFO, legal department, IT department on the client side) lengthens decision cycles. By adopting a sequential or parallel signature flow with configurable delegation levels, the firm reduces its contract timeframes by 70% on missions with strong multi-party dimensions. Qualified eIDAS signature is systematically used for contracts exceeding 50,000 euros in value, in line with the legal risk management policy recommended by major audit firms.

Frequently Asked Questions

What is the difference between a commercial contract and a civil contract?

A commercial contract is concluded between merchants or in the context of a commercial act, and falls under commercial law (Code of Commerce, commercial courts). A civil contract is concluded outside any commercial activity. In practice, B2B contracts are presumed commercial for both parties when they are merchants, which entails specific rules on payment terms, evidence and jurisdictional competence.

Does a verbal contract have legal value in B2B?

Yes, under French law, consensualism is the principle: a contract may be formed verbally if the parties have agreed on the object and price (art. 1113 Civ. Code). However, proving a verbal commercial contract is extremely difficult. Beyond 1,500 euros (art. 1359 Civ. Code), written evidence is in principle required between individuals, but commercial rules of evidence are more flexible. In practice, a signed writing remains essential to avoid any dispute over the scope of obligations.

Which B2B contracts require qualified electronic signature rather than advanced?

Qualified eIDAS signature (QES) is recommended or mandatory for high-stakes financial or legal contracts: sale of business assets, autonomous guarantee contracts, deeds of agreement equivalent to authentic acts, multi-year exclusive distribution contracts. Advanced signature (AES) is sufficient for the majority of standard B2B contracts (service provision, sales, SaaS subscriptions). The choice must be documented in the enterprise's signature policy.

What is the legal retention period for commercial contracts?

Under French law, commercial contracts must be retained for 5 years from their conclusion (statutory limitation period for personal actions, art. 2224 Civ. Code) and associated accounting records for 10 years (art. L. 123-22 C. com.). For property contracts or acts subject to formalities, specific timeframes apply. Electronic archiving with probative value, including qualified timestamping, is the safest method to guarantee document integrity over these periods.

How do you secure an international distribution contract against requalification risk?

To avoid requalification of an independent distributor contract as a commercial agent contract (with the indemnities that entails), several points must be observed: the distributor purchases in its own name and bears economic risk, it freely sets its resale prices (within competition law limits), and the contract does not provide for commission-based remuneration. A well-drafted governing law clause and arbitration clause reinforce legal security in an international context.

Conclusion

The mapping of B2B commercial contract types reveals a complex legal reality: behind each business relationship lies a specific regime of rights, obligations and risks. Sales contracts, service agreements, distribution arrangements, partnership contracts or guarantee contracts — each calls for precise drafting, rigorous qualification and appropriately tailored document security.

In 2026, the dematerialisation of contract processes is no longer optional: mandatory electronic invoicing, eIDAS signature, probative archiving — these requirements apply to all B2B enterprises. Certyneo supports you through this transition by providing a compliant, integrated and intuitive electronic signature solution.
