Booking company-internal expenses

Hello,

In our company, we develop internet platforms and need to transfer small amounts from our business account to these platforms for testing and maintenance purposes. The money is debited from our business account but does not leave the company. How do I have to book these "expenses" correctly? I've thought about creating a clearing account and posting these expenses as "production costs", but I want to make sure this is the right way to go.

Thanks a lot in advance for your help!
