Billing and payment methods

Updated 2026-09-07

Platform carrier rates charge the card on file when you Place Order. Manage that card under Account → Billing.

Open Billing

1. Sign in.
2. Open Account → Billing (/account/billing).

Payment methods

1. Under Payment methods, select Add payment method (or Replace payment method).
2. Complete the payment form and save.
3. Retry any failed Place Order.

Transactions

Use Transactions & carrier adjustments on the same Billing page for payment history and carrier adjustment rows.

When Place Order fails with payment required

1. Add or replace the payment method.
2. Confirm you selected a Nitromule platform rate (not only a BYOA row that failed for another reason).
3. Place Order again.

Postage vs plan

• Postage for Nitromule rates is charged per successful label purchase.
• Your own carrier account postage is billed by UPS/USPS/FedEx under that contract — see Your own accounts.
• After Void, credits follow Refund a label.
