USPS shipping services overview for ecommerce
What is USPS shipping and how it works
USPS® is a go-to carrier for domestic and international delivery, especially for small parcels and daily ecommerce orders. With ShipStation, USPS shipping runs inside a centralized USPS shipping workflow. Orders import automatically, you choose a service, and ShipStation creates the label and tracking number. You can also generate return labels and keep shipment records tied to each order for clean support handoffs.
How to print USPS shipping labels online
Skip the counter. With ShipStation, you can buy postage and create labels from your desk, then print on standard label printers. ShipStation provides access to USPS postage through our partnership, or you can connect your own direct carrier account. Either way, you can print USPS labels from orders automatically using presets, saved package types, and scan-to-ship workflows.
Access discounted USPS shipping rates
Shipping adds up fast. ShipStation helps you access discounted USPS shipping rates, so you can protect margin without changing your packing flow. Get discounted USPS rates without a long setup or renegotiation. You can also compare your own negotiated rates against ShipStation rates in the same screen, so you’re not guessing.
Automate USPS shipping workflows
Your best ship method shouldn’t live in someone’s head. Use automation rules to automate USPS fulfillment workflows based on weight, SKU, tag, destination, or service level. This keeps shipping consistent when volume spikes. Set it once, then ShipStation applies it every time. Common rules include:
- Auto-assign package type and service for repeat items
- Split shipments when an order needs more than one box
Priority Mail® vs First-Class Mail® vs Ground advantage™
Choosing the right service is half the win. USPS Priority Mail® is a strong default for fast delivery on many orders. First-Class Mail® is great for lightweight documents and flats, while USPS Ground Advantage™ is a solid, budget-friendly choice for many everyday shipments. ShipStation makes the decision easier with side-by-side costs and delivery estimates, plus presets that keep your team consistent even on busy days.
Manage USPS and other carriers together
Most brands don’t ship with one carrier forever. ShipStation is a multi-carrier shipping software that supports USPS®, UPS®, FedEx®, GlobalPost, and DHL Express®, plus many more. That means you can use one shipping screen to compare services, print labels, and track exceptions. When a package is heavy, oversized, or time-critical, you can switch carriers without switching tools. Your team stays fast.
Control USPS shipping costs
Cost control is a daily habit. ShipStation helps you optimize USPS shipping costs for businesses with smart defaults, rate comparisons, and batch processing USPS shipments. You’ll reduce trips to the post office by printing at scale, creating end-of-day paperwork when needed, and scheduling pickups where available. For quick planning, use:
