Nitromule

Get UPS, USPS, and FedEx rates

Rate shopping in Nitromule is the Get rates action on Get Label (and on order label flows). You fill Shipping and Packages, get a table of carrier services, then continue to checkout.

Before Get rates works

You need:

  • A Ship From address (set a default under Address book → Addresses → Set default → Ship From)
  • A complete Ship To (street, city, state, ZIP; unit/apartment when the building has one)
  • Package weight and dimensions
  • Optional extras later under Options (signature, insurance, pickup)

Incomplete addresses or missing dims are the usual reason for an empty table — see Rates not showing.

Steps (Get Label)

  1. Open Get Label.
  2. On Shipping, confirm Ship From and enter Ship To.
  3. On Packages, enter weight and L×W×H (add more packages if you are shipping multiple boxes).
  4. Select Get rates.
  5. Review each row: carrier, service, price, and transit when shown.
  6. Select Select service on the rate you want.
  7. Continue through Options (signature, coverage, Dropoff or Pickup) as needed.
  8. Select Continue, then Place Order to pay and create the label.

From an imported order

  1. Open Orders → Incomplete.
  2. Select the order(s).
  3. Select Create Label / Create Labels.
  4. Confirm addresses and packages, then Get rates and finish with Place Order as above.

Buying postage from the order (not a separate ad-hoc Get Label) is what allows store tracking sync — One-off vs order labels.

Reading the rate table

  • Platform Nitromule rates charge Account → Billing.
  • Connected carrier accounts (BYOA) bill under your carrier contract when that rate source is used — Your own accounts.
  • PO Boxes often return USPS only.
  • Adding signature or insurance can change which services remain.

Rates are quotes until you Place Order. Address or package edits require Get rates again.
