Your data stays yours
Mercista has no account, no server and no cloud. Your invoices and customers live on your computer, and nobody else can read them.
About Mercista
Simple business software that runs on your own computer, keeps your data private and costs one fair price.
Why Mercista exists
Most business software now lives in the cloud, bills you every month and stops when the internet does. Many shops need something else: a program that keeps working offline, keeps their numbers private and does not become a yearly bill. Mercista is built for them.
What we stand for
One fair price
A lifetime license is 19.99 $, paid once: no subscription, no yearly fee, free updates.
Works when the internet doesn't
Install it once and keep selling, counting stock and printing invoices with the cable unplugged.
Plain and honest
We tell you what Mercista does and what it does not. There are no hidden extras and no tracking.
What Mercista is not
- It is for Windows 10 and 11 only: there is no phone or tablet app.
- A license works on one computer. Another computer needs its own license.
- The data lives on one computer: several computers do not share it in real time.
- It is not an approved e-invoicing or accounting system. Check your local rules and ask an accountant to review your books.
