The legal obligations of B2B companies go beyond invoicing. With the reform of electronic invoicing, the CSRD sustainability reporting, and the European directive on due diligence, the regulatory framework applicable to inter-company relationships has fundamentally changed since 2024. Understanding each provision, its scope, and its timeline allows for proactive compliance rather than reactive adaptation.
Compliance clauses in B2B contracts: an underestimated lever
Before even discussing invoicing or reporting, the first layer of legal obligation in B2B lies within the contract itself. The compliance clauses inserted into commercial agreements commit each party to adhere to applicable regulations, including anti-corruption standards, international sanctions, and personal data protection.
These clauses are not decorative. They typically provide for an audit right, a reporting obligation in case of non-compliance, and mechanisms for early termination. A supplier unable to demonstrate compliance with GDPR or the Sapin II law risks contract termination without compensation.
The critical point lies in the drafting. A clause that is too vague (“the service provider commits to comply with applicable legislation”) offers no real protection. The operational clauses specify the applicable benchmarks, compliance timelines, and contractual penalties. To delve deeper into these issues, legal information on Manager B2B details the obligations that weigh on commercial relationships between professionals.
B2B electronic invoicing: timeline and actual scope of the reform
The generalization of electronic invoicing between VAT-registered businesses established in France follows a progressive timeline, with final dates yet to be confirmed by regulatory texts.
The system relies on state-approved platforms, which replace the initially envisioned public portal as the transmission channel. Each company will need to choose a platform capable of processing the structured formats recognized by the administration.
The reform is not limited to the dematerialization of invoices. It also includes e-reporting, which requires companies to transmit transaction data that does not fall under the scope of electronic invoicing (operations with foreign clients or individuals, for example). This aspect is often overlooked in preparations, even though it concerns a significant volume of operations for many B2B companies.
What changes concretely for invoicing software
An invoicing software that only handles the classic PDF will no longer suffice. Compliance requires the ability to produce a structured file readable by the approved platform and to manage e-reporting flows. Software publishers are adapting their solutions, but the verification of compatibility remains the responsibility of each company.
CSRD sustainability reporting: which B2B companies are concerned
The CSRD (Corporate Sustainability Reporting Directive) has begun to take effect for financial years starting in 2024. It replaces the non-financial performance declaration with a sustainability reporting structured according to ESRS standards, subject to verification by an independent third party.
In France, the transposition results from ordinance No. 2023-1142 of December 6, 2023, and decree No. 2023-1394 of December 30, 2023. The scope is gradually expanding:
- Large companies already subject to the NFRD (non-financial performance declaration) were the first to be affected, starting with the 2024 financial year.
- Other large companies exceeding certain revenue, balance sheet, or employee thresholds will follow in subsequent financial years.
- Listed SMEs will be integrated according to a staggered timeline, with simplified standards.
For a B2B company, the impact is twofold. On one hand, it may be directly subject to reporting. On the other hand, even if it is not, its large clients will request data on its value chain to feed into their own CSRD report. CSRD compliance cascades through commercial relationships.
European due diligence: obligations in the B2B value chain
The directive (EU) 2024/1760, adopted in May 2024, extends the logic of due diligence already present in the French law of 2017 across Europe. It requires affected companies to identify risks related to human rights and the environment in their value chain, prevent harm, and, for some, adopt a climate transition plan.
Its application is progressive and does not indiscriminately target all B2B companies. The thresholds pertain to employee count and revenue. In practice, mid-sized companies that are not directly targeted will experience the same cascading effects as with the CSRD: their clients will impose traceability and risk documentation requirements in the supply chain.
The contractual consequences are direct. Due diligence clauses in B2B contracts become a tool for transferring responsibility. A supplier unable to produce a mapping of its own risks will lose tenders even before the directive is directly applicable to it.
Data compliance and cybersecurity: the permanent foundation
The GDPR remains the foundation of data compliance in B2B exchanges. Any company that processes professional contact data (names, emails, positions) must have a legal basis, inform the individuals concerned, and secure the processing. B2B subcontractors are bound by specific obligations through the subcontracting contract provided for in Article 28 of the regulation.
Non-compliance in cybersecurity now exposes companies to increased penalties. The NIS 2 directive, gradually transposed into member states, broadens the scope of companies subject to information system security obligations. IT service providers, software publishers, and B2B digital service providers are among the directly targeted sectors.
The accumulation of these regulations creates a dense network. A mid-sized B2B company may find itself simultaneously affected by electronic invoicing, CSRD as a supplier, due diligence through contractual ripple effects, and NIS 2 if it operates in a covered sector. Mapping its obligations before launching compliance projects remains the only way to avoid overlaps and blind spots.
