What documents do I need to prepare for my Thai visa application as an e-commerce business owner?

Hi guys, I posted earlier but for some reason I cannot comment on it so I’m gonna make another post.

So basically, I run an e-commerce business that generates around €50k revenue a year over the past few years but I am putting most of that back into the business as opposed to paying myself a wage. Otherwise I have multiples of the required 500 K in my savings account.

From some of the comments it appears that may not paying myself steadily from the company won’t be a problem as long as I have the savings.

I am wondering, what document I will need to prepare with regard to the above for the portfolio? I will be going through the embassy in London. I’d hate for my application to be rejected and lose the application fee.
