Have you ever put money in a deal? The first bounce payment is always ominous - you worry the merchant moved bank accounts, closed shop, etc. Think about it like this, if the merchant missed the 5th payment on a term of 160 days, that is 3% of the deal paid in. The merchant is ALREADY having issues so early on.
I understand you got the merchant back on track, but that doesn't remove the risk of the merchant screwing the funder once you get paid. There are PLENTY of funders that would have defaulted the merchant and not said anything
