Labels bought. Tracking pushed. Done.

Key benefits
EasyPost integration
Connect your EasyPost account and access all carriers — USPS, UPS, FedEx, DHL — with live rate comparison per order.
Bulk label purchase
Select 50 orders and buy all labels in one batch. Progress indicator shows status per order. Failed labels flagged for retry.
End-of-day scan forms
Generate USPS scan forms for the day's USPS shipments. One barcode scanned at the post office covers all packages.
Label void
Void labels you don't need anymore — right from the order page. Refund hits your EasyPost balance automatically.
Package presets
Save common box and envelope dimensions as presets. Rate quotes are instant when the package type is pre-configured.
Automatic tracking push
Within 60 seconds of buying a label, Lineup pushes the tracking number to the source marketplace. No manual export.
