Decide as a team what tools to use to stay organized. If you are working with team members remotely, consider using tools that allow you to collaborate on single documents instead of emailing back and forth.
It's important to decide how you will manage your search results before you start your project. Choose a system that will allow you to gather your results, remove duplicates, and cite them in your papers. Make sure the whole team agrees on which software to use and that everyone has access to it.

Since you are searching multiple databases you will have duplicate records in your results. You will want to remove the duplicates as far as possible before screening so that you won’t have to screen the same records twice. Reference management and systematic review software often have semiautomatic de-duplication options.
Make sure you keep a record of the total number of results and the number of results after de-duplication to enter into your PRISMA flow diagram.
