For this use case, you may want to look at Lendica's (https://golendica.com/partners) "Checkout" product. Leader in "embedded lending" space for B2B.

really exciting to see what @Pier is building! Some thoughts for below:

Seems you guys are focused on end-to-end software tools and will rely on the business taking credit risk (and getting the balance sheet) instead of providing the loan yourself. Is that correct?

If that's the case, one thing to look out for is it's quite challenging to get your customers (paying $10-20k / mo) to trust your underwriting standards/origination tools. First question will be: why can you do it better?

One model that worked well is Opyn.eu in Italy that offers the software but has an agreement to buy any "loan" back from the creditor over the course of the payment.

Hope that helps and wish you the best of luck!
