ISO 22301 costs and timeline
The investment in ISO 22301 covers setting up your business continuity management system (BCMS), testing and exercising, audit costs and yearly maintenance. You can read the standard at ISO , practical guidance at ISO 22313 , and certification runs through accredited bodies under RvA (Dutch Accreditation Council) supervision .
The biggest cost drivers are scope, supply chain complexity, availability requirements (RTO/RPO) and how much you already have in place.

| Mistake | Result | Better alternative |
|---|---|---|
| Making the scope too broad from the start | Unnecessary complexity and delay | Start with the most critical processes |
| Setting RTO/RPO too late | Unrealistic plans | Make decisions early with management |
| Skipping exercises | A weak audit position | Plan regular tests and lessons learned |
| Forgetting supplier continuity | Recovery stays dependent on third parties | Include vendor continuity explicitly in the scope |
| Not reserving capacity | The project keeps slipping | Agree on owners and time in advance |
