I am trying to write an SOP for my company for the qualification of suppliers (for raw materials and ingredients). I looked it up online and it seems most SOPs include a detailed questionnaire and/or an audit of the supplier's facility.
We are a small company and could definitely not afford to audit our suppliers.
How strong can a qualification procedure be without without an audit?
For the record, until now we are relying on collecting documents (organic cert, spec sheets, etc) and approving each ingredient prior to purchase with analyses, and testing again against our specs upon reception of the material.
I feel like our testing should go a long way in ensuring that each ingredient is safe/meets specs. We don't have a supplier questionnaire (we know that most of our suppliers have their own suppliers who possibly have their own suppliers... so I feel like asking them to detail their handling and QA practices might be a bit besides the point since they are mostly a warehouse with a lot of sales reps).
