VSME Basic vs. Comprehensive: The Complete Guide to the Modules in 2026/2027

Introduction: Navigating the VSME Framework

As we move through 2026 and look toward 2027, the voluntary VSME framework (Voluntary ESRS for non-listed SMEs) has officially established itself as the gold standard for small and medium-sized enterprises navigating the ESG landscape. Developed by EFRAG—the same body of experts behind the EU's CSRD—VSME was created to solve a critical problem: protecting SMEs from being overwhelmed by complex, enterprise-level reporting standards.

However, many business owners and CFOs make the mistake of assuming that VSME is a single, one-size-fits-all checklist. In reality, EFRAG designed VSME as a modular framework. This means your business can choose the specific level of reporting that matches your current resources, your bank's requirements, and the demands of your B2B customers.

Understanding the differences between the Basic Module, the Narrative-Social-Governance (NSG) Module, and the Business Partners (BP) Module is essential to avoid over-reporting or under-delivering. This guide provides a complete breakdown of the modules to help you choose the right path for your SME.

‍

1. The Three Modules of the VSME Framework

The VSME framework is structured into three building blocks. You can start with the simplest module and gradually add the others as your business matures and customer demands grow. To understand how this framework serves as the foundation for modern SME reporting, read our core guide: Understanding the VSME Framework: The Foundation of Wardn’s ESG Reporting Platform.

Module 1: The Basic Module

The Basic Module is the starting point and the minimum baseline for any SME. It is designed to be simple, straightforward, and highly quantitative.

• No Materiality Assessment Required: You do not need to perform a formal double materiality assessment to use this module. The framework pre-defines what is relevant.
• Focus on Key Metrics: It focuses on essential, easily measurable KPIs, such as energy consumption, greenhouse gas emissions (Scope 1 and 2), waste management, and basic workforce metrics (such as gender ratio and employee turnover).
• Primary Goal: To provide a quick, credible ESG baseline for banks, insurers, or early-stage B2B inquiries.

Module 2: The Narrative-Social-Governance (NSG) Module

The NSG Module is an optional add-on that introduces qualitative context to your quantitative data. It is designed for SMEs that want to document how they manage sustainability.

• Policies, Actions, and Targets (PAT): This module guides you through explaining your formal policies, concrete actions, and measurable targets regarding environmental, social, and governance matters.
• Primary Goal: To strengthen your brand, support your employer branding, and provide a structured narrative for stakeholders who want to see the strategy behind your numbers.

Module 3: The Business Partners (BP) Module (The Comprehensive Module)

The Business Partners (BP) Module is the most advanced block of the VSME framework. It is specifically designed for SMEs that are critical suppliers to large, CSRD-regulated corporations.

• Driven by Scope 3 Demands: Large corporate buyers are legally required to report on their value chain emissions. The BP Module includes the specific, detailed data points these buyers need to complete their own Scope 3 reporting.
• Includes Advanced Disclosures: It covers more detailed environmental metrics (including Scope 3 emissions), supplier assessments, and customer-specific ESG requirements.
• Primary Goal: To secure your B2B contracts and position your business as a preferred supplier in the corporate supply chain. Read our guide on how SMEs can meet B2B customer requirements using VSME and Scope 3 reporting here.

2. Side-by-Side Comparison: Basic vs. Business Partners (BP)

To help your management team decide which module to target, let us compare the entry-level Basic Module with the advanced Business Partners (BP) Module across key operational features:

• Target Audience: The Basic Module is designed for micro-enterprises and early-stage SMEs, whereas the Business Partners Module is built for SMEs facing heavy B2B customer demands.
• Double Materiality Assessment: A formal assessment is not required for the Basic Module. However, it is highly recommended for the Business Partners Module to help identify key risks and opportunities. Learn about double materiality dimensions here.
• Scope 1 and 2 Emissions: Reporting on direct and indirect energy emissions is mandatory and quantitative in both the Basic and Business Partners modules.
• Scope 3 Emissions: Value chain emissions are not required in the Basic Module, but they are a core requirement in the Business Partners Module.
• Qualitative Policies (PAT): The Basic Module requires minimal qualitative writing, while the Business Partners Module demands detailed disclosures on formal policies, actions, and targets.
• Primary Commercial Use: The Basic Module is ideal for securing basic bank loans and establishing internal ESG baselines. The Business Partners Module is critical for winning public tenders and retaining large B2B contracts.

3. How to Choose the Right Module for Your SME

Choosing the wrong module can result in wasted resources or lost business. We recommend using the following three scenarios to guide your decision:

Scenario A: "We just need a credible ESG profile for our bank and internal alignment."

• Your Choice: The Basic Module.
• Why: If you are not facing intense pressure from large corporate buyers, the Basic Module is more than enough. It allows you to build a professional, verified ESG baseline without the administrative burden of qualitative policy writing or Scope 3 calculations.

Scenario B: "Our largest B2B customers are sending us complex ESG questionnaires."

• Your Choice: The Business Partners (BP) Module.
• Why: Your customers are trying to complete their own CSRD reporting. If you only deliver the Basic Module, you may fail to provide the Scope 3 and value chain data they legally require. Adopting the BP Module ensures you remain a compliant and highly valued partner.

Scenario C: "We want to use ESG strategically to win new market share and tenders."

• Your Choice: The Full VSME Suite (Basic + NSG + BP).
• Why: By combining all three modules, you create a comprehensive, professional ESG report that covers quantitative metrics, strategic policies, and supply chain data. This complete profile positions your business as an industry leader, giving you a massive competitive advantage in public and private tenders.

4. Automating Your VSME Reporting with Software

Regardless of which module you choose, attempting to collect data, calculate carbon emissions, and format reports manually in Excel is a commercial dead-end. It drains internal resources, increases the risk of errors, and results in static documents that are difficult to update. Read our full comparison of the pros and cons of manual vs. software-based ESG reporting here.

By utilizing a dedicated ESG software platform like Wardn, you can easily manage and automate all three modules of the VSME framework:

• Automated Data Collection: Wardn integrates directly with your accounting systems (such as e-conomic) and utility providers to pull energy and operational data automatically.
• Built-in VSME Workflows: The platform guides you step-by-step through the specific requirements of the Basic, NSG, or BP modules, ensuring you only report on what is necessary.
• Audit-Ready Export: Generate a professional, fully compliant VSME report with a single click, ready to be shared with your customers, banks, or auditors.

Conclusion: Start Simple, Scale as You Grow

The beauty of the VSME framework is its modularity. You do not need to have a perfect, enterprise-grade sustainability strategy on day one.

For many SMEs, the smartest approach is to start with the Basic Module to establish a clean, software-backed data baseline. As your business grows, your B2B customers demand more data, or new regulations emerge, you can easily activate the Narrative and Business Partners modules within your ESG software.

By taking a modular, software-driven approach, you protect your team from administrative burnout while ensuring your business is always ready to meet the commercial demands of the market.

Frequently Asked Questions (FAQ)

1. What are the three modules of the VSME framework?

The VSME framework consists of three modules:

1. The Basic Module (essential quantitative metrics, no materiality assessment required).
2. The Narrative-Social-Governance (NSG) Module (qualitative policies, actions, and targets).
3. The Business Partners (BP) Module (advanced value chain and Scope 3 metrics for B2B suppliers).

2. Does the VSME Basic Module require a double materiality assessment?

No. The Basic Module does not require a formal double materiality assessment. EFRAG has pre-defined the essential environmental, social, and governance metrics within the module, making it the fastest and most cost-effective way for an SME to establish an ESG baseline.

3. Which VSME module should I choose to satisfy my B2B customers?

If your B2B customers are large, CSRD-regulated corporations, you should choose the Business Partners (BP) Module. This module is specifically designed to capture the detailed value chain and Scope 3 carbon data that corporate buyers need to complete their own mandatory reporting.

4. Can we start with the Basic Module and upgrade to other modules later?

Yes. The VSME framework is completely modular. Most SMEs start by automating their data collection for the Basic Module. Once they have a solid data baseline, they can easily layer on the Narrative (NSG) and Business Partners (BP) modules as their commercial needs evolve.

5. How does VSME compare to the full ESRS standards?

The full ESRS (European Sustainability Reporting Standards) are mandatory for large, listed corporations and contain over 1,000 data points and complex disclosure requirements. VSME is a voluntary, highly simplified version designed specifically for non-listed SMEs, stripping away the enterprise complexity while remaining 100% compatible with CSRD demands.
