When you're setting up a restaurant, a cash register is often the first purchase that comes to mind. It makes sense — you need to take payments. But do you really need to invest hundreds (or thousands) in a complex all-in-one cash register system?

For many small restaurants, the answer is no. Here's why.

What a Cash Register Actually Does

A traditional cash register does three things: it records sales, prints receipts, and stores cash. Modern models sometimes add a touchscreen, a card reader, and some basic reports.

The problem is that many all-in-one "restaurant cash registers" sell far more than that. They bundle in order-taking, menu management, kitchen display, analytics — all in one expensive terminal, with a high monthly subscription and often a 12 to 24-month contract.

But those features (order-taking, kitchen display, analytics) aren't the job of a cash register. They're the job of an ordering system — and there are much simpler, more affordable solutions for that.

The Real Question: What Does Your Restaurant Actually Need?

In reality, a small restaurant needs two separate things.

First, a way to take payments. That's the job of a card reader (like Square Reader, SumUp, or Zettle) and optionally a cash drawer. No complex system needed — a simple card reader costs a few dozen dollars.

Second, a system to manage orders. That's the job of an ordering system: take orders at the table, send them to the kitchen, track their progress, and analyse your sales. This software runs on smartphones and tablets you already own.

By separating these two functions, you avoid paying for an expensive monolithic system where you only use a fraction of the features.

Why All-in-One Systems Cost So Much

Cash register manufacturers deliberately bundle payments and order management into a single package. It's a sales strategy that lets them justify high prices and long contracts.

The typical cost of an all-in-one restaurant register includes dedicated hardware (touchscreen terminal, receipt printer, cash drawer) for $500–$2,000, a software subscription of $50–$200/month, installation and training charged separately, and add-on fees for each extra module (kitchen display, table management, etc.).

For a small restaurant or food truck, that's a disproportionate investment.

The Alternative: Card Reader + Ordering Software

The most effective approach for a small restaurant is to combine a simple, affordable card reader with an ordering system on your smartphone or tablet.

The card reader handles payments. Solutions like SumUp or Square cost under $50 to buy, with transaction fees of 1.5–2.6% — and no monthly subscription.

The ordering software handles everything else: taking orders at the table, sending them to the kitchen display (KDS), tracking order status, and sales analytics. It runs on devices you already have.

The result: a complete system for a fraction of the price of an all-in-one register, with no contracts and no dedicated hardware.

How Bistromo Fits Into This Setup

Bistromo is an ordering system that handles everything between the customer's order and the moment they pay: taking orders in the dining room, sending them to the kitchen via the KDS screen, tracking order progress, and sales analytics.

It works alongside your existing card reader — whether that's a SumUp, Square, Zettle, or any other payment terminal. Bistromo doesn't replace your payment method, it complements your setup by adding all the order management intelligence.

The free plan covers up to 300 orders/month, and the Pro plan at $29/month offers unlimited orders. No contracts, no dedicated hardware.

In Summary

An all-in-one restaurant cash register isn't the only option — and for many small restaurants, it's not the best one. By separating payments (simple card reader) from order management (ordering software), you get a more flexible, more affordable system that's easier to scale.
