Set up return label checkout

Updated 2026-09-07

On this page

Return label checkout lets a customer purchase a label that ships a package back to your return address — rentals, repairs, and mail-it-back programs.

When to use returns

  • Gear must come back to your warehouse
  • You do not want to email one-off return PDFs
  • The customer should pay (or you absorb cost via rules/coupons you configure)

For outbound + return together, prefer round-trip checkout.

Requirements

  • Portals-enabled plan
  • Correct return destination for inbound packages
  • Preset packages that match how customers will pack returns
  • Automation / portal package limits that allow inbound lanes to your facility

Setup steps

  1. Create a return portal / checkout flow.
  2. Lock the destination to your return warehouse when the product supports a fixed return-to address.
  3. Add presets (for example “small soft case”, “medium box”).
  4. Configure carriers/services you accept for inbound.
  5. Brand the page and publish the link (email after rental, QR at pickup, etc.).
  6. Buy a test return label yourself and confirm the PDF and destination.

Customer experience

  1. Customer opens the return link.
  2. Optional: enters original order number + email (shown when the portal locks ship-from to your warehouse) to prefill addresses and packages.
  3. Confirms package preset and ship-from (their address).
  4. Pays for the return label.
  5. Prints and drops the package with the carrier.

For Shopify merchants, open returns also sync into NitroMule Incomplete when read_returns is authorized — staff can buy return labels from Orders.

Operational tips

  • Spell out what must be included (serial cards, chargers)
  • Match presets to the outbound packaging when possible
  • Staff the return dock for the carriers you enable
  • Use forms with labels if you need RMA numbers before labeling

Troubleshooting

  • Label ships to the wrong warehouse → fix the portal return-to address
  • Customer cannot get rates → validate their ship-from; check presets
  • Need dashboard-side returns instead → return and round-trip
