The short version

Merchant Fund Express explains payments in plain English so owners can make better decisions about equipment and processing.

Three terms get used interchangeably, and mixing them up leads to expensive misunderstandings.

The POS is the system you use to ring up and manage sales. The processor moves the money between the customer's bank and yours. The gateway is the online connection that lets websites and software send payments to the processor.

Some companies combine all three; others sell only one. Knowing which piece you are buying helps you compare offers honestly.

The steps

POS

Hardware and software where you take the order and the payment.

Processor

The company that handles authorization and settlement.

Gateway

The online link between a website or app and the processor.

Merchant account

The account where your approved sales are deposited.

Tips that help

Ask which of the four pieces an offer actually includes.
Ask who you call when something breaks.
Ask whether you can use the POS with another processor.

A worked example

A retailer buying a new POS learns the quote includes the software and hardware but processing is separate. Asking which piece each line covered let her compare two offers honestly.

Before you decide: three questions

What would I do if it failed on my busiest day?
What does my current setup cost me in lost time, not just fees?
What would I do if it failed on my busiest day?
