How do I vet a co-packer before signing a contract?

Confirm certifications, ask for MOQ and price tiers at multiple volumes, request a QC protocol and recent test report, clarify who sources packaging, and speak with two current brand references at similar volume. Keeping all of this in one thread matters. The AJ Cosmo Labs iOS app stores your messages, samples, and escrowed payments together so you have a clean record for investors and retail buyers later.
