ShowFlow

Why ShowFlow

Stop writing names on tape mid-show.

Screen-reading tools guess at what's on your screen. ShowFlow reads the sale itself, straight from your show page.

How it works

Set up once. Then just go live.

Install ShowFlow

A Windows app plus a small Chrome extension. Pair your Brother label printer the way you already do.

Open your show

Open your live show in Chrome and press Start Watching. ShowFlow shows LINK: LIVE when it's connected.

Sell. Labels print.

Every win prints a label with the buyer, lot number and item, in real time, while you keep selling.

Features

Built during real shows.

ShowFlow was built and tested on a live tool-auction show running 100+ lots a night.

Real-time printing

The label starts printing the moment the auction closes — no waiting until the show ends.

Exact sale details

Buyer username, lot number and the full item title, exactly as they appear in your listing.

Giveaways included

Giveaway winners get their own clearly marked label so nothing gets left out of the box.

No double labels

Each sale prints once, even after a restart or a dropped connection mid-show.

Your brand on every label

Add your logo and a custom line like "Be sure to bookmark our shows."

FAQ

Questions

Does ShowFlow print shipping labels?

No. ShowFlow prints sorting labels during your show so every item is tagged with its buyer and lot. You still make shipping labels in Whatnot afterward — it just goes much faster when everything is already sorted.

Does it bid, chat or click anything for me?

No. ShowFlow only reads the sales on your own show page and prints labels. It never bids, posts or takes any action in your show.

What do I need?

A Windows 10 or 11 computer, Google Chrome, a Whatnot seller account and a Brother QL label printer.

Does it work on Mac?

Not yet. Join the waitlist and tell us you're on Mac so we know how many sellers need it.

How much will it cost?

Pricing isn't set yet. Waitlist members get first access and early-bird pricing.
