A restaurant POS is not a cash register with a tablet. What it should do, how self-service ordering fits in, and what building your own actually costs.
By GGP Editorial
A good restaurant POS does far more than take an order and print a receipt. It sits between the front of house, the kitchen, the inventory, and the payments. When owners call us about building one, the first question is almost never about features. It is about where the current system breaks down.
There are five jobs a restaurant POS has to do, and skipping any of them causes problems you notice in the first busy weekend.
Order taking is the easy part. The harder jobs are sending orders to the right kitchen station, splitting bills, applying discounts and combos, tracking stock so the kitchen stops running out mid-service, and closing the day with numbers that match the card terminal.
Kitchen display systems matter more than most owners expect. Paper tickets get lost, and a cook reads a ticket wrong during a rush. A screen with timers and order states keeps the kitchen honest about what is late. It also gives you data on how long each station takes, which is how you find the bottleneck.
One project we delivered combined self-service kiosks with the POS and card terminals. Customers order and pay at the kiosk, the order goes straight to the kitchen display, and staff spend less time keying orders and more time on the floor.
That setup pays for itself fastest in fast-casual and quick-service places where most orders are simple. For a full-service restaurant it makes less sense, because a server is already at the table. A kiosk only helps if it removes a real step, not if it adds one.
The same logic applies to QR-code ordering. If your menu is long and your tables are busy, letting customers order from their phone can lift the average check. If your menu is short and the server is the experience, skip it.
No POS lives alone. At a minimum you will want a card terminal, and probably a delivery app or two. Online ordering is the other piece: customers now expect to order from the website or an app, and those orders have to land in the same queue as the walk-ins.
The integration trap is thinking each one is a small add-on. A delivery app that doubles an order, or a payment that shows as settled when the terminal declined it, is the kind of bug that surfaces at 9pm on a Friday. Build the reconciliation path for every integration before you go live.
Two smaller things save more time than they look like. Staff accounts with real permissions mean a server can comp an item but cannot void a whole day's sales, and the owner can see who did what. Menu engineering is the other one: your top-selling and highest-margin items should be one tap away, not buried three screens deep. A POS that makes the profitable items easy to order quietly lifts the average check.
Loyalty and repeat customers run through the same screen. If a regular gets a discount or a points balance, that has to apply at the moment of payment, not after the fact. Tying loyalty to the POS instead of a separate app is how most operators actually make it work.
Hardware is the other cost nobody budgets for. Terminals, printers, kitchen screens, and a spare for a rush-hour failure add up fast. Decide whether you want to own or rent the hardware, and keep a spare printer on hand. A dead receipt printer at 8pm on a Friday is a problem you can avoid for the price of one spare.
Costs depend on whether you build from scratch or start from a platform.
| Option | Typical cost | Timeline | Notes |
|---|---|---|---|
| Off-the-shelf POS subscription | $50-300 per month per terminal | Days | Fast, limited customization |
| Custom POS on a platform such as Android | $30k-90k | 3-6 months | Your own workflows and branding |
| Full build with kitchen display and inventory | $80k-200k | 6-9 months | Only for specific needs |
Most single-location owners should buy. If you run several locations, a franchise, or a concept where your workflow is part of the product, a custom build starts to make sense.
Ask any vendor, including us, these four things. Can the system keep working offline if the internet drops? What happens to open orders during a power cut? How does the kitchen display handle an order that gets modified after it was sent? And can the day-close report be exported to your accountant's format?
If a vendor cannot answer those in five minutes, keep looking. The demo screen is never where a POS fails. The failures happen at rush hour, offline, and at the end of the day when the numbers have to match.
