Reduce carrier fees and shipping costs
Industry standards and proven strategies
Our blog focuses on three main areas: NMFC freight classification and PCF density calculations, cost optimization strategies to reduce carrier fees, and logistics best practices including re-weigh prevention and dimensional weight pricing. All content is written for warehouse managers, freight coordinators, and logistics professionals.
We publish comprehensive freight guides monthly, focusing on high-impact topics that directly reduce shipping costs or prevent carrier fees. Each guide is thoroughly researched and includes practical examples from real warehouse operations.
Absolutely! Each blog guide is designed to work alongside our free calculators. For example, our NMFC guide teaches freight class concepts, then you can use our Freight Class Calculator to apply what you learned. The guides explain the "why" and calculators handle the "how."
Most guides focus on LTL (Less-Than-Truckload) shipping since that's where freight classification, dimensional weight, and re-class fees are most critical. However, load planning guides apply to both LTL and FTL. We clearly indicate the shipping mode at the start of each article.
Our current guides focus on US domestic LTL freight (NMFC classification) and parcel shipping (dimensional weight). For international ocean freight, use our Container Load Planner tool. We may expand to international topics like HS codes and Incoterms in future guides.
Yes! Use the contact form in the footer to suggest topics. We prioritize guides that solve real cost problems for warehouse managers. Common requests include carrier contract negotiations, BOL best practices, and avoiding specific accessorial charges.
