EcoVadis officially states that filling out the questionnaire can take "a few hours to a few days". However, any experienced project manager will tell you that the real timeline for a successful assessment, from start to finish, can range from 3 to 9+ months. The exact duration depends heavily on your company's size, complexity, and current level of sustainability maturity. The process is best understood in four key phases: Preparation & Documentation, Questionnaire Submission, Expert Analysis, and Results & Action Planning. The real "heavy lift" of gathering and creating evidence happens long before you even start filling in the questionnaire.

About 'The Answer' Series

The Answer is a series that provides no-fluff answers and solutions to your most pressing EcoVadis questions. We tackle one topic head-on to give you the clarity you need to move forward.

The biggest miscalculation companies make is underestimating the EcoVadis assessment time, particularly the pre-submission preparation phase. This guide provides a realistic EcoVadis timeline to help you plan resources, manage expectations, and avoid common delays.


EcoVadis Timeline at a Glance

This table provides a high-level estimate to help with initial planning. Note that these are typical ranges based on our research, but "mileage will vary". Your company's actual timeline depends on a variety of internal factors.

Phase SME (Low Maturity) SME (High Maturity) Large Enterprise (Low Maturity) Large Enterprise (High Maturity)
Phase 1: Preparation 80-200+ person-hours
over 6-12 weeks
50-100 person-hours
over 4-8 weeks
250-500+ person-hours
over 12-16+ weeks
150-300 person-hours
over 8-12 weeks
Phase 2: Submission 4-8 weeks
(often requires extension)
3-6 weeks 6-10 weeks
(often requires extension)
4-8 weeks
Phase 3: Analysis 6-8+ weeks 6-8 weeks 6-8+ weeks 6-8 weeks
Phase 4: Results & Action Plan 2-4 weeks 1-3 weeks 3-5 weeks 2-4 weeks
Total Estimated Timeline 4-7+ Months 3-5 Months 6-9+ Months 5-7 Months

The biggest delays come from Phase 1. The EcoVadis Starter Pack can reduce this phase by weeks with ready-to-use templates and checklists.


Phase 1: Preparation & Documentation (The Real "Heavy Lift")

This is the most time-consuming phase and involves gathering, creating, and curating evidence.

  • For SMEs (1-999 employees): Expect 50-100 hours for high-maturity SMEs and 80-200+ hours for low-maturity SMEs, spread over 4-12 weeks. The main challenge is often creating new documentation, like a first formal anti-corruption policy or a system to track energy use.
  • For Large Enterprises (1,000+ employees): Expect 150-300 hours for high-maturity large enterprises and 250-500+ hours for low-maturity ones, spread over 8-16+ weeks. The main challenge here is not a lack of data, but organisational complexity and coordinating across siloed departments.

The table below outlines the biggest internal roadblocks that cause delays and how to mitigate them.

Roadblock Timeline Impact Strategic Mitigation
Lack of Internal Buy-In Weeks to months of delay. Other departments de-prioritise data requests, viewing the assessment as "a sustainability problem". Secure executive sponsorship from the start. Frame the assessment in terms of commercial risk and customer requirements, not just compliance.
Disorganized Documentation Significant time wasted. The project team spends most of its time on an internal "scavenger hunt" for documents. Establish a centralised document repository. Use a well-structured shared drive or ESG software to create a single source of truth for all evidence.
Last-Minute Sprint Approach Guarantees a poor-quality submission and a low score. Rushing inevitably leads to missed evidence and incomplete answers. Treat EcoVadis as a year-round "slow burn" project. Begin preparation at least three to four months before the submission is due to allow for proper evidence gathering and review.

Phase 2: Questionnaire Submission & Deadlines

Once the questionnaire is activated, the clock starts on your ecovadis submission deadline.

  • The Deadline: The initial deadline is often 30 business days.
  • The Lifeline: EcoVadis has a built-in feature allowing you to extend your own deadline, typically by up to 60 business days. This should be seen as a strategic part of the project plan, not a failure.
  • Campaign Assessments: If your assessment is triggered by a customer campaign, timelines may be stricter. EcoVadis aligns the deadlines with your customer’s request, usually requiring completion within 12–16 weeks end-to-end.

Phase 3: EcoVadis Expert Analysis

This is the ecovadis review time, when analysts validate your submission.

  • Standard Timeline: Expect to wait 6 to 8 weeks for your results.
  • Variables: This timeline can be extended during high-demand periods or for very complex submissions. Your subscription level may also influence the publication date.
  • The "360° Watch": During this phase, analysts also scan public sources for news and reports about your company, which can impact your score.

Phase 4: Results & Planning for Reassessment

The process doesn't end when you get your score.

  • Scorecard Validity: Your scorecard is valid for 12 months from its publication date.
  • The Real Value: The most valuable part of your results is the "Improvement Areas" feedback. Use this to create a Corrective Action Plan to guide your efforts for the next 12 months.
  • The "Slow Burn" Approach: The most successful companies treat EcoVadis as a year-round continuous improvement project, not a last-minute sprint. Data shows that companies with multiple assessments score significantly higher than first-timers.

๐Ÿ“ Key Takeaways

  • Expect 3-9+ Months: The total EcoVadis timeline is much longer than just the submission window. Plan accordingly.
  • Preparation is Key: The pre-submission documentation phase is the longest and most resource-intensive part of the process.
  • Use Extensions Strategically: The 60-business-day extension is a standard tool, not a failure. Use it to ensure a high-quality submission.
  • Think Annually: The most successful companies adopt a year-round "slow burn" approach to continuous improvement, using the results from one assessment to prepare for the next.

Frequently Asked Questions

Can I speed up the EcoVadis review process?

Yes. While the standard analyst review takes around 6–8 weeks, the "Select" subscription offers a priority feature (target 4 weeks outside peak season). For urgent cases like tenders, EcoVadis also runs "assessment campaigns," which synchronise the review timeline with your customer’s deadlines.

What happens if I miss my submission deadline?

If the deadline expires and you have not requested an extension, the questionnaire will be closed. You may be able to have it reopened by contacting EcoVadis support within six months, but this is not guaranteed and will cause significant delays. It is always better to proactively use the extension feature.

Is the timeline different for a reassessment?

The preparation time for a reassessment is often shorter, as you are building from an established baseline and focusing on the "Improvement Areas" from your last scorecard. However, the official EcoVadis analysis time of 6-8 weeks remains the same.
