How to reduce e-commerce shipping costs

Measure billed weight by product family

Compare physical and dimensional weight after packing. Oversized air inside a box can move an order into a more expensive bracket even when the product is light.

• Physical weight
• Final outer dimensions
• Carrier dimensional divisor

Create packaging rules, not improvisation

Assign suitable envelopes, boxes and protection to repeatable order profiles. Record the final dimensions so carrier comparisons use reality.

Use a route and service matrix

A domestic parcel, an Iberian order and a long-haul export should not automatically use the same carrier. Compare delivery experience, tracking, claims and surcharges alongside price.

Include delivery failure and returns

A cheap first attempt becomes expensive when address quality is poor, tracking is weak or the return route is unclear. Cost per successful order is the more useful measure.
