What merchant level do I qualify for?

Most of the time, this is just a sales pitch. “Merchant levels” are an internal bar that the processor has set- whether in general or a written requirement- with business volume affecting the rates offered.

However, when PCI standards were established, 4 merchant levels were created. This has nothing to do with your cost of processing, although in reality there is a correlation between sales volume, total transactions, and cost per transaction.
