Common mistakes to avoid

Avoid

Oversizing for visual impact

Large empty boxes increase freight and may look wasteful to customers.

Avoid

Using weak board

A beautiful mailer still fails if corners crush during delivery.

Avoid

Forgetting fulfillment speed

Complex inserts can slow packing for repeat orders.

Supplier questions to ask

  • What is the packed product weight and size?
  • Will the mailer need an insert, tissue, pouch or filler?
  • Is inside print necessary or would an insert card work better?
  • What carton packing and delivery route will be used?

Quote readiness checklist

A buyer does not need every detail on day one. The goal is to provide enough context for a realistic supplier route.

  • Product dimensions and packed weight.
  • Number of products per box.
  • Desired unboxing elements.
  • Shipping destination and delivery method.
  • Monthly or repeat order forecast.
