Checklist

• Check carton quantities against the commercial invoice line by line.
• Review the reorder point after one full selling cycle.
• Log sell through by account for the first eight weeks.
• Request batch photographs and a packing list prior to shipment.
• Keep certificates current and filed against the exact model name.
• Verify that artwork matches the approved compliance template.

Commercial terms

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
