Quick answer: Integrated management system certification combines two or more ISO standards — most commonly ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (safety) — into a single, unified management system. For businesses that need more than one standard, an IMS saves time, cost and duplicated paperwork, and is certified by an accredited body in one streamlined audit rather than several separate ones.
Many growing businesses eventually need more than one ISO standard — quality for customers, environmental for tenders, safety for their workforce. Managing those as three separate systems is slow and repetitive. An integrated management system solves that. This guide explains integrated management system certification in plain language and why it’s often the smarter route.
What is integrated management system certification?
An Integrated Management System (IMS) combines multiple ISO standards into one coherent framework, so you run a single set of policies, processes and audits instead of several overlapping ones. Integrated management system certification means an accredited body has audited that combined system and confirmed it meets all the standards you’ve chosen. Because modern ISO standards share a common structure (defined by ISO), they fit together naturally — a quality, environmental and safety system can live under one roof.
In simple terms: one system, one set of documents, one audit — covering several standards at once.
Which standards are usually integrated?
The most common combination is the “big three,” each of which we also certify individually:
- ISO 9001 – Quality Management
- ISO 14001 – Environmental Management
- ISO 45001 – Occupational Health & Safety
Businesses can also add others — such as ISO 50001 (energy) or ISO 27001 (information security) — depending on their needs. Not sure which standards apply to you? Our guide on which ISO certification your business needs can help.
Who needs an integrated management system?
An IMS is ideal for organisations that require (or expect to require) more than one standard, including:
- Manufacturers and industrial units needing quality, environmental and safety standards
- Construction and infrastructure firms juggling multiple compliance requirements
- Larger businesses bidding for tenders that demand several certifications
- Any organisation that already holds one ISO standard and plans to add more
If you need two or more standards, integrated certification is almost always more efficient than certifying each separately.
The benefits of an integrated management system
- Saves cost: one combined audit is cheaper than several separate certification audits.
- Saves time: shared documentation and processes cut duplicated effort.
- Less complexity: one system to run and maintain, not three.
- Consistent management: aligned objectives and reviews across quality, environment and safety.
- Stronger for tenders: demonstrates broad, mature compliance in one go.
How to get integrated management system certification
The process mirrors a single-standard certification, just covering more ground: choose your standards, run a combined gap analysis, build one integrated set of documentation and controls, train your team and pass the Stage 1 and Stage 2 audits with an accredited body. An IMS usually takes a little longer than a single standard but far less time than certifying each one individually. Read the full process in our guide on how to get ISO certification in Guwahati.
