What Is a Factory Audit?

A factory audit is a structured, on-site assessment of a manufacturing facility. Unlike a product inspection that evaluates finished goods, a factory audit evaluates the supplier itself — its management systems, production processes, workforce competence, equipment condition, and ability to meet buyer requirements consistently.

Factory audits are a critical step in supplier qualification. They help importers and brands answer a fundamental question: can this factory reliably produce my product to the right quality, on time, and in compliance with regulations?

Key distinction: A factory audit assesses the supplier's systems and capability. A product inspection assesses the goods being produced. Both are essential, but they serve different purposes in your quality assurance program.

Types of Factory Audits

Depending on your objectives, different audit types focus on different aspects of the supplier's operations:

1. Capability Audit (Manufacturing Assessment)

The most common type. A capability audit evaluates whether the factory has the machinery, workforce, quality systems, and capacity to fulfill your orders. Auditors review production lines, equipment maintenance records, quality control procedures, raw material storage, and overall organizational structure.

2. Compliance Audit

Verifies that the factory meets specific regulatory requirements, buyer standards, or industry certifications. This may include checking for ISO 9001 quality management systems, product safety standards (CE, UL, FDA), or retailer-specific codes of conduct.

3. Social Audit (Ethical Audit)

Evaluates labor conditions and ethical practices. Social audits cover worker age verification, wage records, working hours, health and safety conditions, freedom of association, and anti-discrimination policies. Common frameworks include SA8000, BSCI, SMETA, and WRAP.

4. Environmental Audit

Assesses the factory's environmental impact and sustainability practices. Auditors review waste management, water treatment, emissions control, chemical storage, energy efficiency, and compliance with local environmental regulations.

Audit Type Focus Typical Duration
Capability Production capacity, machinery, QC systems, workforce 1 man-day
Compliance Regulatory standards, certifications, buyer codes 1 man-day
Social Labor conditions, wages, health & safety, ethics 1.5 – 2 man-days
Environmental Waste, emissions, chemical handling, sustainability 1 – 1.5 man-days

Factory Audit Checklist: What Inspectors Evaluate

A professional factory audit follows a structured checklist. Here are the main areas assessed during a standard capability and compliance audit:

Quality Management

  • Quality management system (QMS) documentation
  • Incoming material inspection procedures
  • In-process quality control points
  • Final inspection and testing protocols
  • Defect tracking and corrective action records
  • Calibration of measuring instruments

Production Capability

  • Machinery condition and maintenance logs
  • Production line layout and workflow
  • Monthly and annual production capacity
  • Lead times and on-time delivery history
  • Workforce size and skill levels
  • Training programs and records

Facility & Infrastructure

  • Factory cleanliness and organization (5S)
  • Raw material and finished goods storage
  • Lighting, ventilation, and temperature control
  • Fire safety equipment and evacuation plans
  • Waste management and disposal systems
  • Security and access control

Documentation & Compliance

  • Business licenses and export permits
  • ISO or industry certifications
  • Test reports and lab certificates
  • Supplier management and traceability
  • Customer complaint handling process
  • Continuous improvement initiatives

Factory Audit vs. Factory Visit vs. Inspection

These three activities are often confused but serve distinct purposes in supply chain management:

Activity Scope Output When to Use
Factory Visit General walkthrough of the facility; informal assessment of operations, cleanliness, and workforce Observations, photos, general impressions Initial supplier screening, relationship building
Factory Audit Structured evaluation against a checklist; scored assessment of systems, capability, and compliance Detailed audit report with scores, findings, and corrective actions Supplier qualification, annual review, issue follow-up
Product Inspection Examination of actual goods produced; AQL sampling of finished products Pass/fail report with defect classification and photos Pre-shipment, during production, or container loading
Best practice: Start with a factory audit to qualify the supplier, then use product inspections for each order to verify the goods themselves. A factory visit can be useful as a first screening step before investing in a full audit.

When to Conduct a Factory Audit

Factory audits should be scheduled at strategic points in your supplier relationship. The most common scenarios include:

1

New Supplier Qualification

Before placing a first order, verify the factory can meet your quality, capacity, and compliance requirements.

2

Annual Supplier Review

Conduct yearly audits of established suppliers to ensure continued compliance and identify improvement areas.

3

Quality Issue Follow-Up

After a major quality failure or repeated defects, audit the factory to identify root causes and verify corrective actions.

4

Volume Scale-Up

Before significantly increasing order volumes, re-audit capacity and systems to ensure the factory can handle the growth.

5

Buyer or Retailer Mandate

Many major retailers and brands require factory audits as part of their vendor approval process.

The Factory Audit Process: Step by Step

1

Scope Definition

Client defines audit objectives: capability, compliance, social, environmental, or a combination.

2

Scheduling

Auditor assigned and date coordinated with the factory. Semi-announced or unannounced options available.

3

Opening Meeting

Auditor meets factory management to outline the audit plan, areas to be assessed, and documentation needed.

4

On-Site Assessment

Systematic review of production areas, warehouses, QC labs, records, and worker interviews (for social audits).

5

Closing Meeting

Auditor presents preliminary findings to management and discusses major non-conformances identified.

6

Report Delivery

Detailed audit report with scores, photos, findings, and corrective action plan delivered within 48 hours.

Frequently Asked Questions

What is a factory audit?
A factory audit is a systematic evaluation of a supplier's manufacturing facility. Auditors assess production capability, quality management systems, working conditions, compliance with regulations, and overall capacity to fulfill orders reliably and consistently.
What is the difference between a factory audit and a factory visit?
A factory visit is typically an informal walkthrough to get a general impression of the facility. A factory audit is a structured, documented assessment following a standardized checklist that scores the factory across multiple criteria such as quality systems, capacity, compliance, and working conditions.
How often should factory audits be conducted?
Best practice is to conduct a factory audit before placing a first order with a new supplier, then annually for ongoing relationships. Additional audits should be scheduled after major quality issues, significant changes in production processes, or when scaling up order volumes.
What types of factory audits exist?
The main types are: Capability Audit (production capacity, machinery, workforce), Compliance Audit (regulatory and buyer standards), Social Audit (labor conditions, wages, health and safety), and Environmental Audit (waste management, emissions, sustainability practices).
How much does a factory audit cost?
Factory audit costs typically range from $300-$600 per man-day depending on the country, audit scope, and complexity. A standard capability audit usually takes 1 man-day. Social and environmental audits may require 1.5 to 2 days. AQM BD offers competitive rates across 7 countries. Get a quote for your specific requirements.
What is the difference between a factory audit and a product inspection?
A factory audit evaluates the factory itself — its systems, processes, equipment, and compliance. A product inspection evaluates the actual goods being produced — checking quality, specifications, and defects. Audits assess the supplier's ability to produce; inspections verify what has been produced.
