Shipping software · Head to head
Pirate Ship vs Stamps.com
Both resell USPS commercial rates. One is free, one is $19.99/mo. The question is whether the handful of services Stamps.com adds are worth $240/year.
TL;DR
Pirate Ship matches Stamps.com on USPS commercial pricing for roughly 95% of packages. Stamps.com only wins on very niche USPS services (Media Mail edge cases, Certified Mail with eReceipt, some presort rates). Pick Pirate Ship unless you print Certified Mail daily.
Parity check
Both tools quote the same carrier rates
Shipping apps do not set postage. Carriers do. When two tools both claim USPS commercial pricing, they quote the same number to the cent. The fee difference between tools is software, not postage.
- 01
Ground FedEx 4d $23.33 +$14.15 - 02
Ground Saver UPS 5d $9.18 cheapest - 03
Ground Advantage USPS 5d $9.65 +$0.47
Close call Only $0.47 (5%) separates the cheapest from the runner-up. Free USPS home pickup or a closer drop-off can erase this gap. Pick by convenience, not price, at this margin.

The tool decision is actually the volume-curve decision. Pick based on where your orders are going, not where they are now.
