Most sellers pick a carrier and stick with it. That's leaving money on the table every single day.

Here's what we see with sellers doing 100-1000 orders/month:

The problem: You signed up with one carrier, got "discounted" rates, and never looked back. Meanwhile, carriers change zone pricing quarterly, fuel surcharges shift weekly, and dimensional weight rules get updated without warning.

The fix is simple but most people don't do it:

1. Rate shop every shipment — the cheapest carrier for a 2lb package to Zone 5 is different than a 5lb package to Zone 8. Every. Single. Time.

1. Negotiate with data, not volume — carriers care about your average package value and return rate more than your volume. If you have a low return rate, that's leverage most sellers never use.

1. Zone-skip when possible — consolidating shipments to regional hubs before last-mile delivery can cut costs 15-30% on ground shipping. Most sellers under 1000 orders/month think this isn't available to them. It is.

1. Audit your invoices — carriers overcharge on 5-8% of shipments through dimensional weight miscalculations and late delivery guarantees. That's free money sitting in your account.
