I have been asked to prepare the Suppliear approval program, we have suppliers that we been dealing with like for many years, we get the certificate of analysis from them for each LOT coming into our facility.
The procedure to approval is long i.e. one has to get the potential suppliers to complete the Questionnaire and then they will be approved and an agreement will be signed between the buyer and seller.
Should ask our current suppliers to complete the questionnaire or just make them to sign the agreement would be sufficient.
Another question is how to approve the supplier of Fruits like strawberries as they come directly from Farm, our supplier can't give us any certificate of analysis.
