SellyPOS installs on the computer at your counter. It needs the internet once, to set your shop
up; after that it sells with no connection at all.

## Before you start

- A computer running **Windows 10 (version 1809 or later) or Windows 11, 64-bit**, with at least
  4 GB of memory and 500 MB of free disk space. See the full
  [system requirements and supported hardware](/download/#requirements).
- A Google account for the shop's owner. Setup signs in with it, so Selly Systems can help you
  recover access if you ever lose it.
- An internet connection for setup.

## Install

1. **Choose your edition** on the [download page](/download/). Start with Lite if you are trying
   SellyPOS out, or Professional for its 7-day free trial. Not sure? Use the
   [edition finder](/edition-finder/).
2. **Run the installer** you downloaded. If Windows shows *Windows protected your PC* and an
   unknown publisher, see [the publisher warning](/help/troubleshooting/windows-unknown-publisher/).
3. **Follow the installer's steps.** Leave *Experience SellyPOS* ticked on the last page and choose
   **Finish**: SellyPOS opens.
4. **Sign in with Google** when SellyPOS asks, as the shop's owner.
5. **Choose your country.** SellyPOS fills in your currency, number and date formats and time zone
   from it. You can change any of them later in Settings.
6. **Enter your business details**, then finish setup. The Sales screen opens, ready for your
   first sale.

> **Installing a lower edition over a higher one**
>
If this computer already has a higher edition installed, the installer asks before replacing it.
Your data is kept either way: every edition uses the same records.

## Next

The Sales screen is ready for your first sale. Guides for every task are in the [help centre](/help/).
