How Do You Choose the Right Open-Source Scheduling Software?

So, what features should you be looking for when choosing an open-source scheduling software? Take the below into account when you’re choosing your perfect solution.

Features and functionality

The features the open-source scheduling software offers should be relevant and useful to your business. This seems simple, but you’d be surprised by how many people overlook this obvious aspect.


Hopefully, your business will grow and expand as you become more successful. It’s important that the software you select will be able to manage this.


The software you choose will contain lots of confidential data. This may include online payment information from your customers. Therefore, it’s essential that you choose safe and secure open-source scheduling software.


The cost will be an essential factor for any startup. Keep in mind that the more expensive ones are likely to have more additional features.


Your company may be using other tools such as CRMs, email providers, and calendars. It’s useful if you choose an open-source scheduling app that integrates seamlessly with these.

It’s the kind of app that small and medium business owners, administrators, managers, and key staff in the service industry are using to take their processes and businesses to the next level.

How does it do that? Well, Trafft is a combination of an online no-code platform and human service from a team of service business automation experts. While that’s a mouthful, we can make it simple by saying that it provides all the necessary tools to organize schedules, accept bookings and payments, send reminders, and integrate with other tools.

Trafft differentiates itself from other open-source scheduling apps and tools that automate smaller tasks like online bookings or personal schedules and are usually hard to configure and maintain, and support is hard to get. 

The Trafft app and its team do that by providing support for the complete workflow cycle of a service business and having an extremely intuitive interface and UX. Trafft is also an open-source employee scheduling software.

What does that mean for you? You would not need to waste time on repetitive tasks like calling clients and confirming or rescheduling, and you won’t even need to hire additional people to do that.
