Aggregators sometimes offer business solutions for much smaller businesses that may not meet the revenue requirements of some of the larger merchant banks.

Take care when looking into this type of arrangement, as using a processor may end up being more expensive than using an aggregator. Payment processors should be used when your business is not large enough to meet the requirements for partnering directly with a merchant bank.

You also want to make sure that your processor only charges a discount rate for sales. Otherwise, you will be charged twice if a customer returns an item: once when the item is sold and once when returned. In this case, you’d be charged twice and still not have made an actual sale.
