The basics

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

Hardware

A terminal, handheld or kiosk that takes the order and the payment.

Software

Menus or items, employees, reports and inventory.

Payment processing

The service that moves money from the customer’s card to your bank.

Support

People who keep it all running.

What it means for your business

A modern POS replaces the cash register, the paper ledger and half the spreadsheets. It also tells you what you sold, when and to whom.

The parts of a POS system

Hardware

The device you ring on, the printer, the cash drawer, the scanner and any displays or kiosks.

Software

The menu or catalog, the payment flow, employee logins, inventory and reports.

Payment processing

The connection that approves cards and settles money to your bank.

Support

The people who set it up and answer when it breaks.

What a POS does that a cash register does not

A cash register adds up what you ring and holds the drawer. A POS also knows what you sold, to whom, when and at what margin. It takes every kind of card, records tips and refunds, tracks stock as it moves and shows you reports by item, hour and employee. That information is the real difference: it turns a day's sales into decisions about what to order, when to staff and what to drop from the menu.

Cloud-based versus legacy systems

Modern systems keep your data in the cloud, so the menu, reports and employee list are available from any browser and survive a broken terminal. Older, locally stored systems tie everything to one machine in the back office, which is why a failed computer used to mean a lost week. Cloud-based systems also update themselves, which is why a Clover device looks the same this year as it did last year with new features added.

Signs you have outgrown your current setup

You count receipts at the end of the day to know what sold
You cannot tell which item or hour earns the most
Customers ask for tap or a receipt by email and you cannot give it
You run out of items you thought you had
A second register or handheld would help but your system cannot support it

The software that comes with every device

Employees: individual logins, roles, shifts and permission levels
Reports: sales by item, hour, employee and location, available on the device and online
Loyalty: customer records and rewards that give regulars a reason to return
App Marketplace: a catalog of business apps for accounting, scheduling, marketing and online ordering
Payments: cards, taps and wallets, with tipping, refunds and receipts handled in the same screen
Inventory: live counts, alerts when something runs low and variants for size or flavor

Terms you will hear

SKU

A unique code for each item you sell, used to track stock.

Modifier

An option attached to an item, such as size, temperature or topping.

Batch

The group of the day's approved card sales that is sent for settlement.

Token

A stand-in for a card number that is safe to store.

Cloud-based

Stored and managed online rather than on one local computer.

How it plays out in practice

A bakery that rang everything on a register for years adds a POS and learns in the first month that three items make most of its revenue and that Tuesday afternoons are dead. The change is not the screen, it is the knowledge, and staffing and baking shift within weeks.

A short checklist

Write down what you want to know that you cannot find out today
List every way customers pay now
Count how many people will use the system
Note where payments happen outside the counter
Decide who will own the setup

Common questions

Where can I get help with this?

Call (305) 384-8391. We explain it in plain English and review your statement for free.

Will my current equipment still work?

Sometimes. We review what you have and tell you what can be reused, what is worth replacing and what you should check in your contract before deciding.

What does it cost?

There is no published price list because the right number depends on your volume, card mix and devices. Call for a personal quote and a free rate review.

Do I need a POS for a very small business?

Not always, but even a small stand benefits from a handheld that takes cards, tracks sales and sends a receipt. The question is what you want to know about your business.

Is a POS the same as a card reader?

No. A card reader takes the payment; a POS also runs your menu or catalog, your staff and your reports.
