How do software platforms ensure money is transferred to lender?

Question

I was wondering how do these platforms that allow businesses to sell their invoice/receivable on them ensure that the lender is paid back? What are the ways in which a software platform can ensure that money is redirected/transferred to the lender who purchased invoice/receivable? Is paper contract the only way to make it legally binding on the borrower to payback or is there some automatic way to redirect money to the lender?

Going to need more specifics but it sounds like you're are describing a payment gateway.https://en.wikipedia.org/wiki/Payment_gateway
