Supplier Evaluation and Subcontractor Auditing

An expert assessment of your suppliers’ and subcontractors’ quality, environmental, and occupational safety practices. Know who your operations depend on.

Supply chain issues ultimately fall on your shoulders: a subcontractor’s quality deviation, environmental damage, or workplace accident reflects on your delivery and reputation. In supplier evaluation, an experienced auditor assesses the supplier’s HSEQ practices on-site against your requirements. You receive a well-founded view to support your purchasing and cooperation decisions.

Informed purchasing decisions – not based on promises.

What Supplier Evaluation Means

Supplier evaluation assesses your supplier’s or subcontractor’s management system and practices – how quality, environment, and occupational safety are actually handled.

Focus on the Supply Chain

Internal audits and pre-audits evaluate your own system. Supplier evaluation looks outward: we assess your partners' operations against your and standard requirements.

Information to Support Decisions

The evaluation results support a concrete decision: selecting a supplier, continuing a contract, or developing cooperation. You get a justified view, not just a list of observations.

Meeting Standard Requirements

ISO 9001 requires external suppliers to be evaluated, selected, and monitored using defined criteria. Documented supplier evaluation provides evidence that withstands a certification auditor’s review.

A supplier’s certificate shows the system exists. Supplier evaluation reveals how it works in practice – specifically with your orders and requirements.

Why Supplier Evaluation Pays Off

The more critical the supplier, the greater part of your risks are in another company’s hands. Supplier evaluation reveals these risks before they materialize.

Supplier problems become your problems: subcontractor quality deviations, environmental damage, or workplace accidents directly impact your deliveries, customers, and reputation. Evaluation highlights these risks early.

A certificate or self-assessment form only confirms that a system exists. An on-site evaluation shows how the supplier actually operates – observations are based on evidence, not the supplier's claims.

ISO 9001 requires supplier evaluation and monitoring, and ISO 45001 specifically calls out subcontractor occupational safety. Professional evaluations fulfill these requirements and provide documented evidence for your system.

A well-done evaluation is not a sign of distrust but cooperation development: the supplier receives clear improvement areas, and you get a solid basis to agree on improvements and track progress.

Supplier evaluation pays for itself when even a single supply chain risk is identified before it happens.

How Supplier Evaluation is Conducted

We carry out supplier evaluations as a clear process tailored to the supplier’s criticality and the decision supported by the evaluation.

01

Kick-off Discussion and Scope Definition

We identify which suppliers to evaluate, what decision the evaluation supports, and which requirements are critical for you.

  • Suppliers to be evaluated and their criticality to your operations
  • Evaluation criteria: standard requirements and your own contract terms
  • Schedule and practical arrangements with the supplier

Evaluation is tailored to the supplier’s criticality – no one-size-fits-all.

02

Review of Preliminary Information

We examine the supplier’s documentation and your experience with the supplier before the evaluation visit.

  • Supplier certificates, manuals, and process descriptions
  • Your experience: complaints, deviations, and delivery reliability
  • Evaluation plan and question framework for the visit

The evaluation visit focuses on essentials, thanks to careful preparation.

03

Evaluation Visit at the Supplier

We evaluate the supplier’s operations on-site: interviews, production observations, and evidence requests regarding HSEQ practices.

  • Interviews with management and staff
  • On-site observation of production and work methods
  • Evidence of quality, environmental, and occupational safety practices

Observations are based on what we actually see – not on supplier promises.

04

Report and Recommendation

You receive a report clearly outlining the supplier’s strengths, risks, and improvement areas along with a reasoned recommendation to support your decision.

  • Findings categorized: strengths, risks, and improvement areas
  • Reasoned recommendation: approve, develop, or seek alternatives
  • Review of results together – and with the supplier if agreed

You get a documented basis for purchasing and cooperation decisions.

An evaluation of a single supplier typically completes within a couple of weeks from kick-off discussion to final report. The on-site visit usually lasts a day depending on supplier size and evaluation scope, and may be conducted remotely by agreement.

Who Supplier Evaluation is For

The service is designed for SMEs whose quality, delivery reliability, or compliance depends on suppliers and subcontractors – and who want to base decisions on facts.

Do you recognize your situation from these?

You have outsourced critical processes to subcontractors, whose quality directly affects your product or service.
You are selecting a new supplier or tendering current ones and want a comparable assessment of candidates before contracting.
There have been complaints, deviations, or delays with a supplier, and you want to identify root causes.
Your certificate requires supplier evaluation, but your practice has remained a questionnaire without producing real insights.
Your customers or industry requirements extend into your supply chain, and you must demonstrate subcontractor compliance.
Subcontractor personnel work at your site or worksite, and you want assurance about their occupational safety practices.

We always tailor the evaluation to your situation – from thorough assessments of a single critical supplier to evaluation programs covering your entire supplier base with consistent criteria.

What You Receive

The results of the supplier evaluation are tangible documents that support both your decision-making and your own supplier management system.

Supplier-Specific Evaluation Report

A clear report documenting the supplier’s strengths, risks, and improvement areas with evidence – not impressions or supplier claims.

Well-Founded Recommendation

A clear conclusion to support your decision: does the supplier meet your requirements, under what conditions to continue cooperation, and what improvements to agree upon.

Evidence for Your System

A documented evaluation fulfills ISO 9001’s requirement for supplier evaluation and monitoring and serves as evidence in your certification and follow-up audits.

Once the evaluation is done, your procurement and cooperation decisions are based on knowledge, not assumptions.

Frequently Asked Questions about Supplier Evaluation

How does supplier evaluation differ from internal audit and pre-audit?+
Internal audits and pre-audits focus on your own management system: internal audits are the regular assessments required by standards, and pre-audits are one-time rehearsals before certification. Supplier evaluation looks outward – assessing your suppliers’ or subcontractors’ operations against your and standard requirements. The results support your purchasing and cooperation decisions while also providing evidence for your own supplier management.
Do ISO standards require supplier evaluation?+
ISO 9001 requires organizations to define criteria for evaluating, selecting, and monitoring external suppliers and to keep documented records of evaluations. ISO 14001 and ISO 45001 also require management of outsourced activities, with ISO 45001 specifically highlighting subcontractor occupational safety. Professionally conducted supplier evaluations provide documented evidence for these requirements.
Does the supplier have to agree to the evaluation?+
Yes – the evaluation is always conducted in cooperation with the supplier, and evaluation rights should be documented in procurement contracts. Proper communication ensures evaluations are not seen as distrust but as a normal part of professional supply chain management. Many suppliers find the evaluation beneficial as it gives an external perspective on their operation level.
Can the evaluation be done if the supplier has no ISO certificate?+
Yes. An evaluation does not require a certified system – we assess supplier practices against your requirements and standard principles. Evaluating a non-certified supplier is often the most useful because no external party has previously assessed their operation, producing genuinely new insights.
Isn't the supplier’s own certificate enough?+
A certificate confirms that the supplier’s system met standard requirements at the audit time on a general level. It does not reveal how the supplier operates with your specific orders or if it fulfills your special requirements. For critical suppliers, your own evaluation complements the certificate and focuses precisely on issues important to you.
Can multiple suppliers be evaluated at once?+
Yes. Evaluating multiple suppliers is best done through an evaluation program using consistent criteria for all. This ensures comparable results and helps prioritize development actions and procurement decisions across your entire supplier base.
What does supplier evaluation cost?+
The price depends on the number of suppliers evaluated, the evaluation scope, and site visits. We always provide a clear quote upfront so you know costs before starting. In a free initial discussion, we assess your situation and provide an estimate without obligation.
