Win. Label prints instantly.

The moment you win an auction, your shipping label prints automatically. Zero clicks.

Instant Whatnot win detection

Any thermal label printer

Dymo LabelWriter, Zebra, Rollo, MUNBYN — if your computer sees it, Printly prints to it. No special setup.

Live win feed & history

Every win logged with buyer name, item, price, and print status. Track your show revenue in real time.

All label sizes

4×6, 2×3, 1×3, thermal 58mm and more. Switch sizes between shows in seconds from Settings.

Auto-print or manual review

Let Printly fire automatically on every win, or review first. Your show, your rules.

"I used to pause my show every win to type in the label. Now I don't touch anything. My buyers get their labels faster and I stay in flow. Printly is a must-have Whatnot seller tool."

"Did 80 wins in one show. Every single one printed automatically. No mistakes, no delays. If you sell on Whatnot and don't have this, you're wasting time every single show."

"Setup took me literally 4 minutes. The win feed showing all my wins with prices is a bonus — I use it to track my revenue each show. Best $24.99 I spend every month."
