What documents to submit when I use TaxTim to submit my tax return?

I am a Sole Proprietor and have signed up for individual tax and provisional tax with you. With regards to my Tax documents, can I send you my bank statements and slips, as well as a summary of my payments on an excel document?

Our system currently works in such a way that you go through the process of answering the questions by having a chat with Tim based on the information you have in the excel document and then we complete the tax return for you based on those questions.
