Uk tax and company registration process consultation

Planning to start a private limited company as a foreign national to get more clients . I know it’s easy to setup . I just want to know the process of sales and tax structure . Because this company just for creating a uk invoice . All services doing in other country . Basically I want to legally transfer the invoiced amount to my registered company in India . What are the tax process between this transaction ? Just 20 VAT only ? Or need to pay corporate tax for all income ? ( The company not selling goods only services )

I need a proper consultation regarding this . How can I do it this process effectively . If any one experienced or already doing this bid please
