MarketDay works the booth.
The offline-first booth companion for market vendors — pack smarter, sell faster, and know exactly what every show earned you.
Pack, sell, summarise.



Sell with no signal.
MarketDay is one loop, end to end. Build your pack list the night before. Ring up each sale with a single tap — cash, card, Venmo, or other — even with zero signal. Then close the show to a screenshot-worthy profit summary.
A cash box gives you one number at the end of the night. MarketDay gives you the rest at the table:
- — Did I bring enough — and what am I about to sell out of?
- — How much have I taken so far today?
- — How does that split across cash, card, and Venmo?
- — Did this show actually make me money?
There is no account and no server. Every sale, pack list, and total lives on your device, with a one-tap JSON backup whenever you want one.
MarketDay is the in-person selling piece of Bennett Studio — alongside MarginPrint, BenchStock, and MakerBooks. Every app shares the same local-first storage, backup, and offline foundations, so use MarketDay on its own or with the rest.
Built for the table.
The free tier is fully built and tested today — and the paid upgrades (unlimited shows, season analytics, CSV, multi-day events) are live now. Not for sale yet — it ships when it is good enough to charge for.
MarketDay isn’t for sale yet.
It is built and I use it, but it is not finished enough to charge for. Rather than sell you a rough version and patch it around you, it stays off the shelf until it earns its price.
No date promised — it ships when it is good enough. In the meantime, get in touch if you want to hear when it does.
The honest answers.
Where does my data live? Is it safe?
On your device — full stop. MarketDay is a client-side app: every sale, pack list, and total is stored in your own browser and never sent to a server. There's no account and no backend, so there's no central database of your business to leak. Export a full JSON backup from Settings anytime.
Do I need to be online?
No. MarketDay is offline-first — built for church halls and open fields with no signal. Everything runs on your phone, so there’s never a spinner between you and a sale. It syncs nothing and waits on nothing.
Can it take payments?
MarketDay records how each sale was paid — cash, card, Venmo, or other — so your end-of-day totals reconcile by payment type. It doesn’t process the payment itself: you still take cash or run your card reader as usual, and log it in one tap.
Is it an app I install?
It’s a web app you can install. Open it on your phone and “Add to Home Screen” — it runs full-screen like a native app, works offline, and updates itself. No app store, no download, works on iPhone and Android.
What does it cost?
Nothing yet — MarketDay is still in development and is not for sale. When it is ready it will follow the same shape as the rest of the studio: a free tier that stays free, and a paid tier for people who outgrow it.
Do I need MarginPrint too?
No — MarketDay works on its own. If you also use MarginPrint, the two are built to pair: they share the same local-first storage, backup, and offline foundations, so the app that costs and queues what you make sits naturally next to the one that sells it at the booth.
Your booth, one phone.
MarketDay is still being built. It is not for sale yet, and there is no date — it ships when it is good enough to charge for.
Release notes only, and not often.
