When a combined system makes sense
Start with the standards your buyer actually asks for.
An integrated management system, or IMS, combines ISO 9001 for quality, ISO 14001 for environmental management and ISO 45001 for occupational health and safety. It is useful when your business needs more than one of these standards for the same legal entity, sites and work activities.
Construction and M&E contractors
For businesses asked by tender owners, developers or main contractors to show quality, environmental and safety controls for the work they carry out.
Manufacturers and engineering firms
For teams that need one way to control customer requirements, operational risks, suppliers, incidents, corrective actions and management review.
Businesses adding standards
For a company with one ISO certificate that expects to add another standard within the next year or two and wants the shared system designed early.
Procurement and management teams
For decision-makers comparing proposals who need to see the certificate scope, responsibilities, timeline and the separation between consultant and certification body.
Before we quote. Send the tender or customer requirement, standards needed, business activity, legal entity, headcount, sites, deadline and any current ISO certificates. We confirm what needs to be included and what your team already has.
Integrated management system process
Build the shared system once. Use it before audit.
ISO 9001, ISO 14001 and ISO 45001 share the same high-level structure. We build the common parts together, then add the quality, environmental and safety controls that apply to your work before the certification body checks the system.
- 01Confirm the requirement and scope
We review the tender or customer clause, standards, legal entity, sites and activities. You confirm what must appear on each certificate and the target date.
- 02Review what you already use
We compare your current documents and records with the three standards at the same time. You receive a gap list that separates shared actions from standard-specific actions.
- 03Build the IMS
With your team, we prepare the integrated policy, process map, responsibilities, document control, risk registers and the controls that fit your work.
- 04Use and review the records
Your team uses the agreed records in normal work. We complete the internal audit and management review work, then prepare the people the certification body may interview.
- 05Prepare for certification
The independent certification body reviews readiness at Stage 1 and implementation at Stage 2. It decides whether to issue the certificates. ZES prepares the system and your team for those audits.
IMS project deliverables
Shared documents, clear owners and audit evidence.
The exact document list follows the standards, certificate scope and work activities agreed for your project. A typical IMS brings the shared controls together while keeping the quality, environmental and safety requirements clear.

$2,288
ZES ISO implementation consultancy starts from $2,288. Your final fee depends on the standards required, headcount, certificate scope, sites and the documents or records already in place. We give you a written quote after reviewing the requirement.
Your written quote sets out
- The ISO standards, legal entity, sites and activities in the proposed certificate scope
- The gap analysis and shared or standard-specific records to be prepared with your team
- The responsibilities, project plan and target timeline
- Internal audit and management-review support
- Preparation for the certification body's Stage 1 and Stage 2 audits
Certification body audit fees are separate from ZES consultancy. The certification body sets its fees based on factors such as headcount, sites and audit scope.
Planning the combined project
Plan from the deadline back to the audit.
Most SMEs working with ZES are certified to ISO in two to four months. An IMS project covering several standards, sites or activities can need more time, especially where new controls and records must be used before the certification body's audit dates.
What helps the project move
- The tender or customer requirement and deadline are available at kickoff
- One project contact can coordinate management, operations and site staff
- Existing process records, risk assessments and certificates are ready to review
- The legal entity, sites and activities for the certificate scope are clear
What can add time
- Several sites, legal entities or varied activities are included in scope
- The project adds more than one new ISO standard
- New controls or records need time to be used in normal work
- Certification-body audit dates do not fit the tender or customer deadline
*Typical SME ISO timeline: from kickoff through the certification body's audit process. Your written quote sets out the timing for the standards, sites and scope agreed for your project.
Before the certification audit
What the auditor needs to see across the system.
The certification body audits one management system against each standard in the agreed scope. Before Stage 1 and Stage 2, we check that the shared controls and the quality, environmental and safety evidence match the work your team does.
The scope matches the requirement
The legal entity, sites, activities and ISO standards on the proposed certificates match the tender, customer requirement and the work actually carried out.
Shared processes are used once
Document control, competence, corrective action, internal audit and management review are consistent across the system, with one clear method for your team.
Risks have the right controls
Quality risks, environmental aspects and occupational health and safety hazards are recorded separately where needed, with controls that fit the work in scope.
Records come from normal work
The auditor can sample customer, purchasing, operational, inspection, incident or review records that show the system is being used.
Management has reviewed performance
The management review covers the required inputs for the agreed standards, actions have owners and the records show what was decided.
People know the audit plan
Relevant people can explain their part of the system and know what the certification body's Stage 1 and Stage 2 audits cover.

Case study: one system across an acquired group
An electronics manufacturer acquired a three-company group with more than 50 distributors in Singapore. Each company had its own ISO 9001, ISO 14001 and ISO 45001 certificates and management system.
Everything was digital, yet each company used different forms. Some forms existed in several versions, some years old. Numbering was inconsistent, with no version control and no single place for the current form.
We reviewed the documents and systems with the staff. Staff were reluctant to change, as each team was used to its own way of working. We listened to their concerns and worked out the shared rules with the department heads of each company. Those meeting rounds took around three months before implementation began.
We set common numbering and version rules and put the current forms in one place. We trained around 40 staff, from accounts and HR to operational management.
After around three months of meetings, ZES Consulting merged three companies' ISO 9001, ISO 14001 and ISO 45001 systems into one integrated management system in Singapore in a further three months. The three companies share the same forms, numbering and version rules. Staff document work without doubting which version is current.
Send ZES the list of certificates each company holds and one sample form from each. We reply within one working day.

Scope, cost, timing and certification.
Short answers for Singapore business owners, project teams and procurement managers. If you are still deciding which standard applies, read the ISO 9001, ISO 14001 and ISO 45001 comparison.
What is an integrated management system?
An integrated management system is one management system that meets the requirements of more than one ISO standard. For ISO 9001, ISO 14001 and ISO 45001, the shared parts can include the policy, process map, responsibilities, document control, internal audit, corrective action and management review. The quality, environmental and safety controls still need to match your actual work.
Do we get one certificate or three?
If the independent certification body certifies all three standards, it issues one certificate for ISO 9001, one for ISO 14001 and one for ISO 45001. The certificates can be supported by one connected system and a combined audit programme, but the certification body decides the audit arrangement and certification outcome.
Do we need all three standards?
Not always. Start with the certificates the tender, contract or customer explicitly requires. ISO 9001 is commonly requested for quality management. ISO 14001 is relevant where environmental management is required. ISO 45001 covers occupational health and safety management. Send the clause before committing to a wider scope.
How much does an integrated management system cost?
ZES ISO implementation consultancy starts from $2,288. The final fee depends on the standards required, headcount, certificate scope, sites and the records already in place. Certification body fees are separate. After reviewing the requirement, we provide a written quote that shows what is included.
How long does IMS certification take?
Most SMEs working with ZES are certified to ISO in two to four months. An IMS can take longer when it covers several standards, sites or activities, or when new controls need time to be used in normal work. Audit availability also affects the final schedule.
Can we add another ISO standard later?
Yes. Tell us early if you expect to add a standard within the next year or two. We can design the shared parts of the system so the next standard can be added without rebuilding the common controls. The added standard still needs its own scope, technical controls, evidence and independent audit.
What does my team need to do?
Choose one project contact and make the people responsible for management, operations, purchasing, sites and safety available to explain their work. Your team confirms the scope, reviews the documents, uses the agreed records, joins the internal audit and management review, and is available for certification-body interviews.
Who audits and issues the certificates?
An independent accredited certification body audits the IMS and decides whether to issue the ISO certificates. At Stage 1 it reviews readiness and documents. At Stage 2 it samples records and speaks with staff about how the system is used. ZES is separate from the certification body and prepares your team for the audits.
What if the certification body raises findings?
Your team needs to address the findings and provide the evidence requested before certification can be issued. We help you work through the points and prepare the evidence. The certification body decides whether its requirements are met, so we do not promise an audit outcome.
