Systematic due diligence eliminates manufacturing surprises before deposits are wired.
Vetting an apparel supplier requires checking concrete evidence rather than trusting verbal promises. This 8-point due diligence framework helps brand founders systematically evaluate factory identity, sample fidelity, in-line quality control, payment milestones, and social compliance before issuing purchase orders.

Questions
Frequently Asked Questions
Why is a manufacturer due diligence checklist essential for fashion startups?
A structured checklist prevents founders from rushing into agreements based on polished website photos. Verifying business licenses, sampling procedures, AQL 2.5 QC systems, and deposit terms protects your financial capital.
What is the most critical item to verify on a factory due diligence checklist?
Verifying physical factory existence and confirming whether production takes place in-house or via un-audited third-party subcontractors. Subcontracting without brand consent is the #1 cause of quality failures.
