Question 1

What is e-commerce shipping optimization?

Accepted Answer

E-commerce shipping optimization is the process of reducing shipping costs and improving delivery performance through a combination of carrier contract negotiation, multi-carrier strategy, invoice auditing, packaging improvements, and data visibility. The goal is to reduce per-shipment costs without changing service levels or switching carriers.

Question 2

How much can e-commerce businesses save by optimizing shipping?

Accepted Answer

The typical savings range is 10 to 30 percent of total annual shipping spend, depending on the current state of carrier contracts and which strategies are applied. Shipware's clients have averaged 21.5 percent savings across all engagements. Individual case studies document savings from $300,000 to $8.5 million annually.

Question 3

Do I need to switch carriers to reduce shipping costs?

Accepted Answer

No. Most shipping optimization strategies work with your existing carriers. Contract renegotiation, invoice auditing, accessorial charge reduction, and DIM weight optimization all apply to current carrier relationships. Multi-carrier strategies may add regional carriers but do not require abandoning UPS or FedEx.

Question 4

When is the right time to renegotiate a carrier contract?

Accepted Answer

You can renegotiate a carrier contract at any time, not just at expiration. After a general rate increase announcement is a particularly strong moment: carriers have already communicated increases, but the actual implementation has not yet happened, giving you a window to negotiate before the new rates take effect.

Question 5

What is dimensional weight and why does it matter for e-commerce?

Accepted Answer

Dimensional weight (DIM weight) is a calculated weight that carriers use when a package is light but takes up significant cubic space. The formula is package volume divided by 139 (for most UPS/FedEx services). When DIM weight exceeds actual weight, you are billed at DIM weight. E-commerce businesses shipping lightweight products in large boxes often pay DIM weight charges that far exceed what actual weight would cost.
