Stamps.com is one of the longest-running online postage solutions in the US. The platform connects directly to USPS, giving sellers access to discounted postage rates without requiring trips to the post office. Sellers can print shipping labels from any standard printer and schedule carrier pickups from their location. The platform integrates with major e-commerce platforms and marketplaces, pulling in orders and pre-filling shipping details. Batch processing lets high-volume sellers generate hundreds of labels in minutes. The built-in tracking system monitors package delivery status and can automatically update order tracking information on selling platforms. For Amazon FBM sellers who ship primarily through USPS, Stamps.com provides meaningful savings on postage costs. The discounted rates often pay for the subscription within the first few shipments each month. The platform is particularly popular among sellers shipping lightweight items where USPS rates are most competitive.
