My previous employer offered commercial leases on equipment. I cannot speak for how Everlast leases work, but my previous employer found a leasing company to do the leasing work, rather than become a "bank" for the customer. My employer sold the equipment to the leasing company, who leased the equipment to the customer. So at that point, all transactions are with the leasing company, rather than the originator, and regardless how good a relationship you had with the seller, you're now dealing with a bank.
One thing I saw is that the leasing companies came up with a multiplier figure to represent the amount owed each month. I suspect they make that figure deliberately vague to hide the amount of interest involved.
The Everlast process may be completely different, but i encourage you to do the math and figure out the interest amount, and compare that to the cost of buying an Everlast from Amazon with an Amazon credit card, for instance.
