If you're setting up a new shop or café, it's a fair question: do you actually need a POS system, or will a plain cash register do the job? The honest answer depends on how much you want to know about your own sales — and today, it doesn't have to cost you anything either way. First, it helps to be clear on what the terms mean, because they're often used interchangeably.
What Is a POS Cash Register?
"POS" stands for point of sale — the moment and place where a customer pays for something. For most of the last century the cash register was the point of sale, so the two terms meant the same thing.
Today they've drifted apart. When people say cash register now, they usually mean a standalone electronic till: it adds up a sale, works out the change, prints a basic receipt and pops the drawer. When people say POS system or POS cash register, they mean a software-driven checkout — a till, but one that also records every item sold, keeps a running product catalogue, and sends that data to reports you can open later.
So a POS cash register isn't a different machine. It's the same job — taking payment at the counter — done by software that remembers what happened. That software can run on a dedicated terminal, a tablet, or, in Sicada's case, an ordinary web browser.
What a Traditional Cash Register Does
A cash register totals up a sale, calculates change, and opens a drawer. That's it. It doesn't know what you sold, how much stock you have left, or which items are actually making you money. Every one of those answers has to come from you, counting and checking by hand.
What a POS System Adds
A point of sale system does everything a register does, and because it records every line item, it can also:
- Keep a running product catalogue with prices and categories
- Track how much stock you have left as you sell (usually a paid feature)
- Show you your best- and worst-selling products
- Break down revenue by day, week or month
- Separate cash sales from card sales automatically
- Let more than one staff member ring up sales under their own login
- Keep checkout working through an internet outage and sync once you're back online
Cash Register vs POS System: Full Comparison
| Feature | Cash register | POS system |
|---|---|---|
| Upfront cost | One-time hardware purchase | Often $0 to start |
| Ongoing cost | None | Free plan, or a monthly subscription for advanced features |
| Hardware | Dedicated till you buy | Runs on a phone, tablet or computer you already own; printer and drawer optional |
| Sales tracking | Totals only — no record of what sold | Every line item on every sale |
| Inventory | No | Yes — live stock tracking, commonly a paid feature |
| Reporting | None | Sales history and reports by day, week and month |
| Multi-user access | No | Yes — staff ring up sales under their own login |
| Offline operation | Always (it never goes online) | Varies by provider — some, like Sicada, keep checkout working offline and sync later |
| Cash & card payments | Cash yes; card needs a separate terminal | Records both; card runs on your own terminal unless the POS bundles processing |
| Receipts | Printed, basic | Printed or digital (emailed or sent by link) |
| Best use case | A stall or shop with a few items and no need for reporting | Any shop that wants to know what's selling, carry more than a handful of products, or add staff |
How Much Does a POS System Cost?
POS pricing usually has up to four parts, and a small shop often pays for only the first one — or nothing at all:
- The software. Many providers, including Sicada, have a genuinely free plan covering the cashier, a product catalogue and full sales history. Paid plans — typically a monthly subscription — add live stock tracking, an analytics dashboard and extra staff accounts. Sicada's paid plans are $19.99/month for Pro and $49.99/month for Business, less if you pay yearly; the Free plan stays $0 forever, with no credit card and no trial.
- Card processing. This is separate from the POS software. If you take card payments, your card processor charges a percentage of each card sale — that fee goes to the processor. Some POS companies bundle their own processing and take a cut; others, like Sicada, just record the sale while the card runs on your own terminal, so you keep your existing processor and rates.
- Hardware (optional). A web-based POS runs on a phone, tablet or laptop you already own. A receipt printer, cash drawer or barcode scanner are add-ons you can buy later — none are required to start.
- Add-ons. Loyalty programs, advanced reporting and priority support are sometimes charged separately or reserved for higher plans.
Compared with a cash register — a one-time hardware cost with no software and no reporting — a free POS system usually costs less to get started, because you're using hardware you already have.
The 3 Main Types of POS Systems
POS systems are usually grouped by where the software runs:
- Legacy (on-premise) POS. The software is installed on a dedicated terminal or a local server in the shop. Data lives on that machine, updates are manual, and you typically pay a larger upfront licence. Common in large or long-established retailers.
- Cloud-based (web) POS. The software runs online — often right in a web browser — and your data is stored in the cloud, so you can open your reports from anywhere and updates happen automatically. This is the usual choice for new small businesses. Sicada is a cloud POS: it runs in any browser, and it also keeps checkout working if your connection drops.
- Mobile POS (mPOS). A phone or small tablet paired with a card reader, used to take payment anywhere — a market stall, a customer's table, a pop-up. Many cloud POS systems, Sicada included, also work as an mPOS on a phone.
A fourth category is increasingly common: self-service and kiosk POS, where the customer rings up their own order on a screen or scans a QR code. Sicada's QR-menu ordering for cafés is an example of this.
When Is a Cash Register Still Enough?
A traditional cash register can be the right call when:
- You sell a small, fixed set of items and prices rarely change
- You genuinely don't need to know which products sell best
- You have no plans to add staff who need their own logins
- You want a device that does one thing, with no account and nothing to learn
- You have no reliable power or internet and want the simplest possible tool
For a market stall, a single-owner kiosk, or a shop with a dozen products, a register still does the job.
When Should You Switch to a POS System?
A POS system starts to earn its place once:
- You carry more than a handful of products and want a catalogue with categories
- You want a real sales history — every transaction, not just a daily total — so you can see trends and your best sellers
- You're adding staff and want each person to ring up sales under their own login
- You want cash and card totals separated automatically at the end of the day
- You'd like a proper receipt for every sale — printed or on screen — or to take orders at the table or by QR code
For a general shop, Sicada's Free plan gives you the catalogue and sales history without a subscription; live stock tracking and the analytics dashboard are on the paid plans. If you run a growing retail store, Sicada also handles barcode scanning, with stock tracking on the Pro plan. And because a modern POS runs on hardware you already own, switching from a register usually costs nothing to try.
The real comparison isn't cost. A free, web-based POS system usually costs less upfront than a physical register once you factor in hardware — the real difference is that one gives you data about your business and the other doesn't.
