USPS shipping integration: commercial rates, Cubic Pricing, and labels from the order
USPS label software with commercial pricing built in — Priority Mail, Priority Mail Express, Ground Advantage, Media Mail, and Cubic Pricing compared live against UPS, FedEx, and DHL, printed to the thermal printer you already own.
USPS is the easiest carrier to set up in Rilk — no separate account negotiation required. Commercial rates pull in automatically the moment you connect.
What you can do
Buy USPS labels at commercial pricing
Without negotiating your own contract. Commercial rates pull in automatically and beat retail by a meaningful margin on most parcels.
Rate-shop USPS
Against UPS, FedEx, and DHL on a single screen so you ship the cheapest service that meets the delivery date.
Print USPS labels
Directly to your existing thermal printer. No PC Postage account, no separate label software.
Media Mail
For the SKUs that qualify — books, audio recordings, video recordings, printed music — at the cheapest domestic rate USPS offers.
Cubic Pricing
For small, dense parcels where size beats weight on the rate card. Rilk computes the cubic dimension automatically when your SKU has the data.
Void or refund a label
You didn't use and the credit lands back against the order automatically.
Track every package
Without leaving Rilk. Status updates flow into the order, and tracking links get pushed back to the marketplace.
What's supported
Frequently asked questions
Do I need my own USPS account to print labels in Rilk?
No. Rilk provisions commercial-rate access when you connect USPS, and you can print in the same session. If you already have a USPS account or Mailer ID you can attach it so postage bills to your account.
What is Cubic Pricing and does Rilk support it?
Cubic Pricing is USPS's rate tier for small, dense parcels where size beats weight on the rate card. Rilk supports it and works out the cubic dimension automatically when your SKU carries dimensions.
Does Rilk charge a fee per USPS label?
No. Printing labels on USPS is included on every plan, starting free. You pay postage and nothing to Rilk for the label.
Can I rate shop USPS against UPS and FedEx for the same order?
Yes. Every order shows USPS, UPS, FedEx, and DHL rates side by side with transit time.
