There is no legal requirement to obtain an ISO certification. In some businesses, customers may not work with uncertified suppliers.
For example,
1. If you offer food-related products, your customer can expect to have an ISO 22000. This is because customers have no clue to trust the publications that the supplier produces.
2. If you are a manufacturing company, your customer can expect ISO 9001. Because customers do not trust that your products and service are quality.
We do not produce; does that mean that ISO does not apply to us?
No. Since different standards like this are lined up, there will be a standard to cover a wide variety of needs. The five common standards listed below work well with most companies.
