Stop Paying Monthly for POS Software.
POSAIC runs on your devices — no server, no internet required, no monthly fees. Install and start selling in 5 minutes.
How? Software costs nothing to copy. We only charge for services that cost real money — or nothing at all if you use our card processor.
Current Reality
Sound Familiar?
"$100/month just for basic POS software."
"Internet goes down and we can't take orders."
"We have no idea who has access to our sales data."
"Adding a second register costs extra every month."
What we build
Here's How POSAIC Fixes That
No Server. No Downtime.
No central server. Every device works on its own and syncs directly with the others over your local network. No central server. When the internet drops, orders, kitchen tickets, and inventory keep flowing.
Free Forever
Not a trial, not a trick. POSAIC is 100% free POS software. Period.
Use Your Own Devices
Already have a laptop, tablet, or old iPad? That's your POS terminal. No special hardware needed.
Works Without Internet
Internet goes down? Orders, KDS tickets, inventory, and receipts keep running — entirely on your device. Cash sales always work; card auth uses your processor's offline mode. Cloud sync resumes when the connection comes back.
Your Data, Your Device
Sales data is encrypted and stored on YOUR device. No one else can access it. Optionally sync to the cloud.
Know Your Numbers
10 real-time reports: sales trends, best sellers, staff performance, cash tracking — all built in.
AES-256 Encryption
AES-256 encryption protects every transaction. Your customer card data is never stored.

Our founder has been building software for three decades — and spent the last 15 years deep in the POS industry, installing, configuring, and repairing systems for small businesses across NY and NJ.
After watching merchants get trapped by $100/month fees, systems that crash without internet, and vendors who hold data hostage — he decided to build something better. With AI as a development partner.
