A webhosting account with the following settings and software are required:

- PHP v4 or PHP v5
- MySql v4 or MySQL v5
- PHP Setting: Register_globals turned OFF
- PHP Setting: Safe Mode OFF
- PHP Setting: Magic Quotes turned ON
- PHP Setting: GD needs to be supported.
- Webserver (Apache/IIS/PWS) on Linux/Unix/Windows

For best security is it also reccomended that your host allows .htaccess files to block users from getting access to certain directories.

PDF Invoices
If you also want PDF invoice (html invoice is default), you must have a Linux software called HTMLDoc installed on your server. Not all webhosts offer this. HTMLDoc is available as Commercial and Free version software you can install as an administrator of your server. The Free version is a bit trickier to install and find for the plattform you may need, but this is the one we have used ourself.

This is from the HTMLDoc hompeage:

"Binaries for HTMLDOC are available on the Easy Software Products download page to users that have purchased a commercial license for the software. Free binaries may be available elsewhere - search Google to find them."
