The frustration was specific. Finding clear, honest shipping cost information for small sellers was harder than it should have been.
Shipping a product to a customer seems straightforward until you get your first carrier invoice and realize you were charged more than expected. Not because you did anything wrong. Because the pricing model is more complex than it appears on the surface, and most of the explanations available online are written by companies trying to sell you something.
Dimensional weight is one example. The concept is not hidden. Carriers publish their divisors. But the practical implications, specifically how box size affects your cost at different weights and zones, require calculation that most blog posts skip entirely. They mention the formula and move on. This blog doesn't move on.
Not a logistics brokerage. Not a software reseller. Not affiliated with any carrier. There are no sponsored posts and no affiliate commissions embedded in platform comparisons. When Pirate Ship is compared to ShipStation, the comparison is based on what each platform actually costs and does, not which one pays a referral fee.
The absence of a business model tied to your decisions is intentional. It's the only way to write honestly about rate comparisons.
Small makers. DTC brands with one to a few employees. Etsy sellers who have outgrown Etsy's shipping tools. Shopify store owners who set up their shipping settings once and haven't revisited them. Anyone shipping physical products without a dedicated logistics person on staff.
The posts assume you understand what a shipping label is but don't assume you've ever negotiated a carrier contract or built a cost-per-order spreadsheet. Both extremes are handled in separate posts.
Each post focuses on one decision. Not a broad overview of shipping. One specific choice: which box size to use, whether to enable cubic pricing, how to read a carrier invoice. The goal is that after reading, you can do something differently. Immediately.
Where numbers are involved, there's a downloadable spreadsheet. No email required. The file is linked in the post and available directly.
Being based in Philadelphia means Zone 3 to most of the Northeast and Zone 5 to the West Coast. That zone distribution shapes which carrier services make sense. Posts reflect that context while noting where the math differs for other starting points.
If you're shipping from the Midwest or the West Coast, some rate comparisons will look different for you. That's noted where relevant, and the spreadsheets are set up so you can enter your own zone.
Claims without numbers are opinions. Every cost comparison includes the actual calculation so you can verify it yourself.
Carriers adjust rates annually. Posts are reviewed and updated when those changes happen so comparisons stay accurate.
No referral programs, no carrier partnerships, no software commissions. The only interest here is accurate information.
General advice is everywhere. Posts here focus on specific scenarios with specific numbers so the information is actually usable.
