What about an option to suspend a website? improved invoices will be fine, it will be usefull to check pays and debts.
As workaround, you can delete thes ite. It is then in the recycle bin. You can can restore sites from the recycle bin.
You can improve the invoices too. Its almost usefull but it will be great if ISPC can generate invoices monthly (or every X months). One more thing, add someway to get the client information from the sites page. Now i have to create clients with the site name as Title or add folders on the Site subfolder for everyclient to keep the sites sorted. On more.. jeje.. what about an automatic option to backup the entire server (config, sites, databases, everything) every x days on an external ftp? it would be great to do a cron job for this, and you can add an option to retrieve this backup and put the system as it was before. mmm no more ideas.. but ill be thinking
