Card 1 has an approval of $16,000. You send invoice 1 to merchant for 5% of the $16K = $800.
Card 2 has an approval of $25,000. You send invoice 2 to merchant for 5% of the $25K = $1250.
Card 3 has an approval of $9,000. You send invoice 3 to merchant for 5% of the $9k = $450.

Card 1 is delivered to the merchant in 3 days.
Card 2 is delivered to the merchant in 7 days.
Card 3 is delivered to the merchant in 10 days.

So would you collect the fees as follows???
When card 1 comes in (3 days), Merchant pays invoice 1 with card 1.
When card 2 comes in (7 days), Merchant pays invoice 2 with card 2.
When card 3 comes in (10 days), Merchant pays invoice 3 with card 3.

That method seems so nice and neat! The merchant that is trying to get money, is not having to come out of any money on the front end to facilitate this deal..

Everyone wins!

Now is this how you all go about collecting on fees? If not what is the method?

Precisely.
I can do this with personal loans as well, but those require income verification. However, inquiries are less of a challenge when we go that route.
