Case Study: How Contractbook Turned ESG Into a Sales Advantage

Introduction: Trust and Credibility in B2B Sales

In B2B sales, credibility is built fast, or it is not built at all. For modern software-as-a-service (SaaS) companies, walking into a sales call with a prospect means being prepared to answer tough questions about security, scalability, and, increasingly, sustainability.

With environmental and social concerns rising among enterprise clients, ESG documentation is no longer a post-sale compliance checkbox—it is an early-stage differentiator. Contractbook recognized this shift early on and made the strategic decision to treat ESG as an offensive sales tool rather than a defensive compliance chore.

By partnering with Wardn to build and publish a transparent, public ESG profile, Contractbook has successfully turned sustainability reporting into an active commercial advantage. This case study explores how they did it and how other small and medium-sized enterprises (SMEs) can replicate their success.

The Company: Who is Contractbook?

Contractbook is a leading collaborative contract management platform based in Denmark. The company enables all departments within an organization to manage their contracts in one centralized place with confidence, ease, and automation.

Built on a foundation of transparency, trust, and scalability, Contractbook has earned a reputation as a forward-thinking industry leader. When it came to establishing their ESG strategy, they wanted their positioning to reflect the same level of innovation and leadership that drives their core product.

The Challenge: Rising ESG Expectations in Sales

As EU regulations like the Corporate Sustainability Reporting Directive (CSRD) have rolled out, large enterprise customers have faced immense pressure to audit and report on their supply chains. This "trickle-down" effect means that procurement departments are now legally required to collect verified ESG data—such as Scope 3 emissions and labor standards—from their software vendors.

Contractbook began noticing a significant increase in the number of ESG-related questions appearing in early-stage procurement questionnaires and Requests for Proposals (RFPs).

Instead of waiting to be asked and scrambling to fill out manual spreadsheets for every individual prospect, Contractbook set out to:

• Equip their sales team with a distinct competitive edge in active deal cycles.
• Build trust early in the sales process by signaling responsibility and professionalism.
• Reflect their core company values with verified, transparent data rather than vague marketing claims.

As Viktor Heide, Chief of Staff at Contractbook, explains: "We didn’t want to wait. We wanted to lead."

The Solution: A Shareable, Professional ESG Profile

To solve this challenge, Contractbook partnered with Wardn to publish a polished, public ESG report linked directly from their website and integrated into their sales outreach.

This was not about checking boxes or writing long, qualitative PDFs that nobody reads. It was about storytelling, signaling, and seizing the commercial narrative.

"Coming in hot with a link to your online ESG report, early in a competitive deal scenario, will make you the good-looking benchmark that the competition now has to live up to. It’s like being the only one in the friend group who brought flowers on Valentine’s Day. You're ahead of the game."

— Viktor Heide, Chief of Staff, Contractbook

By structuring their report around the VSME framework (Voluntary ESRS for non-listed SMEs), Contractbook ensured that their data was fully aligned with European standards and directly addressed the compliance needs of their enterprise B2B buyers.

• Reduced RFP Friction: Having a centralized, public source of verified ESG data has dramatically reduced the time spent answering manual procurement questionnaires.
• Enhanced Brand Trust: The public ESG report, linked directly from their website, reinforces Contractbook's commitment to transparency and professionalism.

"We believe trust and security are key. Publishing our ESG report signals that we take our responsibility seriously, both as a Danish startup with momentum and as a team that wants to lead by example."

— Viktor Heide, Chief of Staff, Contractbook

Frequently Asked Questions (FAQ)

1. How did Contractbook turn ESG into a sales advantage?

Contractbook turned ESG into a sales advantage by proactively publishing a verified, public ESG report built on the VSME framework using Wardn. Instead of waiting for prospects to ask for sustainability data, Contractbook's sales team shares their public ESG profile early in competitive deal cycles. This builds immediate trust, satisfies enterprise procurement requirements, and sets a high benchmark that competitors struggle to meet.

2. Why should SaaS companies proactively report on ESG?

SaaS companies should proactively report on ESG because their enterprise B2B customers are legally required under CSRD to document the sustainability of their supply chains (Scope 3). Proactive reporting eliminates sales friction, reduces the time spent filling out manual procurement questionnaires, and positions the SaaS vendor as a low-risk, highly compliant partner.

3. What is the best ESG framework for tech startups and SaaS companies?

The VSME (Voluntary ESRS for non-listed SMEs) framework is the absolute best framework for tech startups and SaaS companies. Developed by EFRAG, it is fully aligned with the CSRD requirements of large corporate buyers but simplified to match the operational reality of smaller businesses, focusing strictly on material, actionable metrics.

4. How can an SME automate its ESG data collection?

An SME can automate its ESG data collection by using dedicated software like Wardn. Wardn integrates directly with utility registries (such as eloverblik.dk) to pull energy data automatically, and connects with financial accounting systems to track supplier spend and calculate Scope 3 emissions. This eliminates the need for manual Excel sheets and ensures the data is audit-ready.

5. How does a public ESG profile help with enterprise procurement?

A public ESG profile helps with enterprise procurement by providing a single, transparent source of truth for all environmental, social, and governance data. Procurement teams can easily verify the supplier's carbon footprint, labor standards, and data security policies without sending back-and-forth questionnaires, significantly accelerating the sales cycle.
