Looking for a software development program to create a rostering system

My College Information Systems class are currently searching for a software development program (with a preference for an App) which is able to create and manage a rostering system for a small business. Any recommendations? We have limited coding skills but can fork out money for a good program.

It must be able to manage and edit databases, be able to input time off requests and similar types of data

Thankyou for any help
