ShipStation vs Stamps.com
Auctane owns both tools (they acquired Stamps.com in 2018). Despite the shared parent company, the products target different users: Stamps.com is USPS-only, ShipStation is multi-carrier.
TL;DR
ShipStation wins for multi-channel ecom sellers (Shopify + Etsy + Amazon). Stamps.com wins for USPS-only sellers who want the absolute best USPS rates. Both cost about the same at 100 orders/month.
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.
