Running IT-Consultant company with employees working for bank

Hello there,

We are in the process of starting an IT company that focuses on hiring out IT consultants in development and IT Support. We will have employees who are employed at our IT company and be hired IT consultants for e.g. Banks within the IT department.

My question: If I am the owner of an IT consulting company and we have employees who work for a bank as IT consultants. Is it allowed to send an invoice to the customer (bank) that our employees perform the work and take profit from money coming from a bank?
