There are countless web applications that can help your business with daily tasks. Ticketing systems, private clouds, file and project management are just a few. Best of all, most of them are Open Source, so all they need it's a web server and a hosting package. Here are a few examples:
HESK allows you to setup a web based ticket support system (helpdesk) for your website. Nextcloud is the most deployed self-hosted file share and collaboration platform on the web. Kanboard is a project management software and it's made for people who want to manage their projects efficiently and simply. Matomo is the leading open-source analytics platform that gives you more than just powerful analytics. And you own your data.
Those applications are FREE and can be run on your own hosted server. Pronto Design can help you with hosting and support monthly plans, whether it's for your private or business use.
