Organisations with several locations
Multi-site ISO certification: coordination, scope and audit planning
For a business with several sites, the first step is an accurate picture of what happens at each location. Multi-site certification depends on how the management system is organised and on the applicable rules. The number of addresses alone does not determine the certificate structure or visits.
What coordinated management means
IAF MD 1 describes a single management system with an authorised central function, centralised management review and an internal audit programme covering all sites. Eligibility for site sampling is assessed separately and is not automatic. See the MD 1 technical reference.
In practice, ask who can require and track the same change across all locations. In a coordinated organisation, a recurring issue at two sites reaches someone able to decide resources, responsibilities and deadlines. A shared procedures folder is useful, but the discussion also needs to address how teams actually work.
Build an operational map of the locations
Before requesting a proposal, prepare a table with one row per location. Distinguish administration, production, storage, services and temporary activities. Where one site performs several activities, state each explicitly.
| Field | What it clarifies |
|---|---|
| Address and site lead | Where work takes place and who can explain it. |
| Processes and services | Shared activities and location-specific operations. |
| People and shifts | When teams and operations are available. |
| Coordination | Who approves documents and follows up issues. |
| Planned changes | Relocations, extensions, new sites or closures. |
Add a backup contact for each site. This simple arrangement helps ensure an absence does not block access to explanations and records.
Prepare the differences as well as the similarities
Two warehouses may share software while having different equipment, hours and workflows. Record relevant differences in receiving, specialist storage, maintenance, temporary staffing or outsourced services.
Ask each site lead for an example of ordinary work and an example of a resolved problem. Together, these provide a better starting point than a general statement that every site works identically.
European Accreditation clarifies that interviewing a site representative at headquarters is not equivalent to auditing that location. Planning should allow assessment of the relevant operations, beyond meeting a representative. Read the EA clarification.
Example: headquarters and four warehouses
Consider a company with an administrative headquarters and four warehouses. Three receive and dispatch goods; the fourth also assembles products. This is a preparation scenario, not a predetermined audit arrangement.
Instead of sending five addresses alone, prepare a one-page map showing where orders are received, work is performed, results are checked and complaints are managed. Highlight assembly because it changes the description of that warehouse’s activity.
This gives the certification body relevant information to review the configuration. Avoid calculating visits yourself from an online formula or assuming a new site automatically enters an existing scope.
Arrange access and team availability
Identify who provides access at each location, where records are held and when operations take place. Communicate protective equipment needs, site inductions and confidentiality restrictions in advance.
Keep a simple register of open questions: location, topic, owner, deadline and answer. For a nonconformity, also describe how you check whether the situation could occur elsewhere. Continue with our corrective action guide.
Where several standards are involved, use the same site map in the discussion about an integrated audit.
What to clarify before a proposal
A well-prepared enquiry explains which activities need assessment, the locations involved, how they are coordinated and what will change. Add existing certificates and the next assessment date if a certification cycle is already underway.
InterConformity can use this structure to discuss the request and applicable next steps. The assessment arrangement, documents and schedule are established after reviewing the situation and confirming the applicable rules and editions.
Frequently asked questions
Must every site perform exactly the same activity?
Describe both shared processes and differences. The assessment arrangement is established after reviewing the organisation and applicable rules.
What happens when we open a new site?
Inform the certification body and clarify assessment and document updates before presenting the new site as included in the certification.
