Aftercare is different to support in the sense that it covers any additional work to your website after completion.
This could be updating to the latest version of WordPress, or updating the theme/ plugins. Or it could be adding some new banners, content or designs to your website to keep it fresh. Of course, you will be able to do most things in the admin panel yourself, although we can help with whatever you are unable to do yourself, or if you do not have the time.
