From setup to packing up — one app handles it all.
No card terminal, no account binding, works offline at your booth.
BOO-POS is a checkout tool built specifically for market booths.
Screenshots show the Traditional Chinese UI — the app interface supports ZH / EN / JA. Tap the coffee cup (SET) on the home screen → Language.
From browsing to checkout — every step clear, nothing in the way.
Lay out products as a photo wall, swap categories, tap once to add to cart. While the customer is still looking, you're already ready to ring them up.
Denomination panel adds up; due vs. paid clear at a glance.
Enter what the customer hands over — the change appears on the spot. Tap denomination buttons to add them up. Even at peak hours, no fumbling, no miscounts.
One-click CSV import; toggle pickup status instantly.
Import your pre-order list as a CSV before the event, search by name on site, mark as picked up. Who got theirs, who hasn't — one glance and you know.
Schedule every event in one app, year-round.
One market this weekend, another next month — each gets its own event slot. Products and records stay separate, no resetting between, lined up clean all the way to year-end.
Never miss a freebie or a discount.
Set a spend threshold and the app reminds you to hand out the bonus gift at checkout; order-wide discounts apply in one tap. You set it up; the app remembers the rest.
Take your inventory with you; no order lost on handoff.
Back up inventory and product data — product images included — to a file and share it with helpers. They import it and keep selling on their own phones. No re-uploading products, no cloud, more hands on the booth.
Product photos as a wall, tap to checkout
Quantity tracking; low-stock alerts
Quick change calc, customizable payment tags
Bundle-gift reminders; order-wide discounts
Every transaction logged automatically; easy to reconcile
Multiple events kept separate; no resetting between markets
CSV import; verify pickups on the spot
When you're running a booth on your own, things can get hectic fast.
You're still tracking sales with pen and paper,
and once the booth gets busy, it's easy to forget a bonus item or miss a special gift.
Sales records, change, freebies, discounts, inventory, pre-order pickups——
whether it's a big booth or a small one,
everything on the table is a piece of work someone stayed up day and night to bring to life.
And yet, there has never really been an intuitive booth POS app made specifically for creators.
Through my encounter with Vibe Coding,
I was finally able to turn an idea I had carried for a long time into a real app,
combining it with my own years of experience running booths at doujin events and markets.
BOO-POS = Booth + POS
The name sounds a little like a dog's bark,
and it took the shape of my favorite beagle.
I hope this little companion will continue to stay by your side
through every day you spend running your booth.
Sell at overseas markets. Stop tallying bundle discounts in your head.
Currency switching: existing events and orders keep their original currency. The switch only affects newly created events.
Bundle pricing note: if a helper is covering the booth, they need to set up bundle pricing on their own app for it to take effect.
This is the first release on record — once the next version ships, this one will be archived here.
