Final thoughts 

In order to pick the best open source scheduling software, you have to first analyze the needs of your organization and its expectations from those tools. A cheat sheet on things to look at before looking for open source scheduling software:

The type of business - this is the foremost requirement you have to look at. If your business offers appointments to customers you need to go for a tool that will streamline your appointment booking process. Select software that meets your specific needs instead of offering many features that are useless for your business.

A number of employees - if you are a freelancer or manage a small team, a free version would do the job at the beginning. But if you manage a large team or hold lots of meetings on a daily basis, then go with enterprise open source scheduling software that gives value for money.

Budget - and of course, price is a crucial factor when picking the best open source scheduling software. Do a price-feature comparison of each available option. Make sure that you get the best bargain under your budget.
