Why tenders now demand ESG from SMEs

ESG is now a scored tender requirement for SMEs—often 10–30% of the evaluation—even when you’re not legally in scope of CSRD. Here’s why and how to respond fast.

Public and private buyers are rapidly baking ESG criteria into their procurement scoring, even when SMEs are not legally in scope of heavy regulations like CSRD. For a small supplier, that means losing a bid is now just as likely to come down to “weak sustainability evidence” as to price or technical quality.

Why buyers demand ESG evidence from SMEs now

Large corporates must report on value‑chain impacts and therefore push structured ESG questions, templates, and portals down to their suppliers.

Public buyers are aligning green public procurement with EU sustainability rules, expecting auditable environmental and social data as a condition of award.

Market standards such as CSRD/ESRS and the new VSME guidance are turning ESG from “nice to have” into a de‑facto language of tenders.

For SMEs with 50–100 staff, this creates a paradox: they are small enough to lack an ESG team, but large enough to face complex, recurring ESG questionnaires in almost every meaningful tender.

The SME tender reality: too small for consultants, too big for Excel

For an SME bidding on public or large private contracts, a typical tender now includes a dedicated ESG or sustainability section, often weighted 10–30% of the total score. Yet internally, ESG work is still distributed between Finance, HR, Operations, and sometimes the founder, without a common system.

  • Each ESG questionnaire consumes 20–50 hours in spreadsheets and email, especially the first time the buyer asks for emissions, workforce, or governance data.
  • Different people copy‑paste slightly different numbers and narratives, leading to inconsistent KPIs across tenders and years, which undermines credibility.
  • Hiring consultants for every bid is prohibitively expensive; waiting to “get ESG sorted later” risks outright disqualification or a failing score on the sustainability lot.
  • SMEs end up firefighting ESG sections at the last minute instead of building a reusable reporting backbone.

What Complezy does for tender-driven SMEs

Complezy is an ESG questionnaire and data management platform built specifically for mid‑market suppliers that must respond to recurring ESG demands from customers. For SMEs bidding on tenders, it becomes the central ESG workspace and reporting engine that turns sustainability from a risk into a competitive edge.

  • Central ESG workspace: input core environmental, social, and governance data once (emissions, energy bills, workforce stats, policies, certifications) and keep it structured for reuse.
  • Questionnaire engine: upload tender ESG forms (PDF, Word, Excel); Complezy parses questions, maps them to your existing data, and proposes draft answers for review.
  • Professional outputs: generate branded, audit‑ready PDFs or spreadsheets aligned with the buyer’s requested format, with consistent numbers and attached evidence.
  • Collaboration and audit trail: assign questions to Finance, HR, or Operations, track status and deadlines, and keep a record of exactly what was sent, when, and by whom.

How Complezy helps win more public and private tenders

For SMEs in the 50–100 FTE range, the question is not “do we care about ESG?” but “can we prove it clearly within the tender deadline?”. Complezy is framed around concrete tender outcomes: higher ESG scores, fewer disqualifications, and faster bid turnaround.

  • Respond in hours, not weeks: once data is set up, repeat tender questionnaires can be turned around in under 24 hours rather than starting from zero each time.
  • Look like a top-tier supplier: consistent metrics, clear narratives, and evidence-backed responses signal professionalism and reduce perceived risk for evaluators.
  • Support public GPP expectations: structured data on climate, workers, and governance makes it easier to meet green public procurement and social criteria without drowning in paperwork.
  • Align with emerging SME standards: exports can be mapped to simplified SME-oriented standards (such as VSME), giving buyers confidence that your reporting is recognizable and proportional.

A practical playbook for SMEs using Complezy

SMEs under 100 FTE do not need a massive ESG transformation project; they need a simple, repeatable workflow that turns tender ESG sections into routine work. Complezy is designed to support exactly this type of lean, pragmatic setup.

  • Centralize what buyers already ask for: collect the 10–20 ESG data points that keep recurring in tenders (energy use, emissions estimates, accidents, diversity, training, key policies, certifications).
  • Standardize your core ESG story: draft approved narratives on topics like climate strategy, employee wellbeing, and governance practices and reuse them across tenders.
  • Run every new tender through the questionnaire engine: upload the ESG annex, auto-map questions, refine answers with the right internal experts, then export a polished annex.
  • Improve once, benefit across all bids: update a metric or policy once; every future tender response benefits automatically, building a credible track record over time.
