There are two answers this question, it must be made clear that we have two products, Invoice Financing  and Business Term Financing 

For Invoice Financing you can not withdraw your invested amount from the investment opportunity as the funds have been disbursed to the SME and is only due to the investor at the end of the tenor. So you can not withdraw your funds before the financing tenor is up.

For Business Term Financing, your payments will be made monthly. So if you receive your payments in month one, the funds will go to your Funding Societies account and you can withdraw that amount into your personal bank account. You will not be able to withdraw any amount that is yet to be repaid back to you.
