How Square Register Works as Your Payment Terminal and Cash Register

What Square Register Does and Who Uses It

Square Register is a point-of-sale system that combines a payment terminal, cash drawer, and sales record-keeping in one device. It processes card payments (credit, debit, digital wallets), holds cash, prints receipts, and tracks what you sold—all on a single iPad or Android tablet. You don't need a separate cash register, a separate card reader, or separate accounting software; Square Register does all three.

Restaurants, retail shops, salons, food trucks, and service businesses use it because the hardware is affordable to buy or rent, the monthly fees are transparent, and you can see your sales and money in real time. You can also run it offline—if your internet drops, the terminal keeps working and syncs transactions once you're back online.

Square Register is not the only point-of-sale system available. Clover, Toast, Lightspeed, and others offer similar bundles. The choice depends on what your business needs to track, how many locations you have, and what integrations matter to you (inventory, scheduling, accounting software, delivery platforms).

Key Takeaways

• Square Register combines a payment terminal, cash drawer, and sales tracking on one device, so you don't buy or maintain separate equipment.
• You pay for the hardware upfront or rent it monthly, then pay a percentage of each card transaction plus a small fee for cash transactions.
• The system works offline and syncs when your internet returns, so a dropped connection doesn't stop you from taking payments.
• Square Register integrates with Square's other tools (invoicing, online ordering, payroll) but requires more setup if you use a different accounting or inventory system.
• You own the data—sales records, customer information, transaction history—and can export it or move to another system if you choose.

Hardware: What You Get and What It Costs

Square Register runs on an iPad (7th generation or newer) or Android tablet that you provide, or you can buy a Square-branded tablet. The actual payment terminal is a small reader that connects to the tablet via Bluetooth. You also get a cash drawer (a lockable box that pops open when you ring up a sale) and a receipt printer.

If you buy the hardware outright, a basic Square Register setup costs between $300 and $600 depending on whether you add a second monitor, a kitchen printer, or a barcode scanner. If you rent the equipment month-to-month, you pay roughly $30 to $80 per month depending on what devices you include. Renting makes sense if you're testing the system, running a seasonal business, or don't want to own equipment.

The tablet itself is not included in the rental price if you don't already own one—you either bring your own or buy one separately. Square does not lock you into their hardware; you can use any compatible iPad or Android tablet, though Square's own tablets come pre-loaded with the Register app.

How Payments and Fees Work

When a customer pays with a card, Square Register sends the transaction to Square's payment processor. You pay a percentage of the sale (the rate depends on your industry and whether the card is present or not) plus a small per-transaction fee. For in-person card payments, rates typically range from 2.6% to 3.5% plus $0.10 per transaction, but the exact rate depends on your business type and your agreement with Square.

If a customer pays with cash, Square Register doesn't charge a processing fee—you keep the full amount. However, some Square plans charge a small monthly fee (around $0.50 to $1.00) per cash transaction to cover the cost of tracking it in the system.

Square also charges a monthly subscription fee for the Register software itself, which ranges from $0 (for the free tier with limited features) to $99 per month for the full suite. The free tier lets you take payments and track basic sales; paid tiers add features like staff management, advanced reporting, and integrations with other Square services.

You can see your fees and payouts in real time in the Square Dashboard. Square deposits your money into your bank account daily or weekly, depending on your settings. You can also hold money in a Square Cash account if you prefer.

What Square Register Tracks and Reports

Square Register records every transaction: what was sold, who sold it (if you assign staff members), when it happened, how much it cost, and how the customer paid. You can run reports on sales by hour, day, week, or month; by staff member; by product category; or by payment method. These reports live in the Square Dashboard, which you access online from any device.

The system also tracks inventory if you set it up—you tell Square what items you sell and how many you have, and the Register deducts from that count each time you ring up a sale. You can set low-stock alerts so you know when to reorder. However, inventory tracking requires you to enter your products into Square first, which takes time if you have hundreds of items.

Customer data is stored in Square's system. If a customer pays with a card or gives you their phone number, Square can link repeat purchases to that person. You can use this to send receipts, loyalty offers, or marketing messages—but only if the customer has consented. You own this data and can export it or request it in a standard format if you leave Square.

Integrations: What Works With Square Register

Square Register connects directly to other Square products: Square Online (your e-commerce website), Square Invoices, Square Appointments, and Square Payroll. If you use multiple Square tools, they share customer and sales data automatically, so you don't have to enter information twice.

Square Register also integrates with third-party software, but the list is limited compared to larger systems like Toast or Clover. Common integrations include accounting software (QuickBooks, Xero), delivery platforms (DoorDash, Uber Eats), and loyalty programs. You can check Square's app marketplace to see what's available for your industry.

If you use accounting software that Square doesn't integrate with, you can export your sales data as a CSV file and import it manually. This works but requires extra steps each time you want to sync. If integrations are critical to your workflow, compare Square Register to competitors before committing.

Security, Offline Mode, and Data Ownership

Square Register is PCI-DSS compliant, which means it meets the security standards required to handle credit card data safely. Your payment data is encrypted, and Square doesn't store full card numbers on your device. When you process a payment, the card information goes directly to Square's secure servers.

If your internet connection drops, Square Register keeps working. You can continue taking card payments and cash payments; the terminal stores the transactions locally and sends them to Square once you're back online. This is important for businesses in areas with spotty internet or for outdoor events.

You own your sales data and customer information. Square does not own your business records. If you decide to leave Square and switch to a different point-of-sale system, you can export your transaction history, customer list, and product catalog. The export process varies depending on what data you need, but Square's support team can walk you through it.

Comparing Square Register to Other Systems

Square Register is one option among several. Clover (owned by Fiserv) offers similar hardware and software but with different pricing and integrations. Toast is built for restaurants and includes more advanced features for kitchen management and delivery. Lightspeed is stronger for retail inventory. Each system has different strengths depending on your industry and size.

The main trade-off with Square Register is simplicity versus features. Square is easy to set up and use, which appeals to small businesses and solo operators. But if you run a large restaurant with multiple kitchens, a retail chain with dozens of locations, or a complex service business, you may outgrow Square Register and need a more specialized system.

Before choosing, list what you need: payment processing, inventory tracking, staff management, customer loyalty, integrations with specific software, multi-location support, or advanced reporting. Then compare how each system handles those needs and what it costs. Many systems offer free trials, so you can test the interface and see if it fits your workflow.

Getting Started: Setup and Training

Setting up Square Register takes a few hours if you're starting from scratch. You create a Square account, add your business information and bank details, choose your subscription plan, and order or rent hardware. Once the hardware arrives, you download the Square Register app, sign in, and connect your devices (tablet, card reader, cash drawer, receipt printer).

The harder part is entering your product catalog if you have one. You'll need to list every item you sell, assign it to a category, set its price, and decide whether to track inventory. For a coffee shop with 30 items, this might take an hour. For a retail store with 500 items, it could take days. You can do this gradually—start with your most common items and add the rest later.

Square offers online training videos and a help center, and you can contact their support team by phone, email, or chat. Support is included with all paid plans. If you're not tech-savvy, ask a friend or hire a local consultant to help with setup; the cost is usually worth the time saved.

Frequently Asked Questions

Can I use Square Register if I don't have internet?

Yes, Square Register works offline. You can take card and cash payments, and the terminal stores them locally. Once your internet returns, the transactions sync to Square automatically. However, you won't be able to access reports or customer data while offline.

What happens if I want to switch to a different point-of-sale system?

You can export your transaction history, customer list, and product catalog from Square. The process depends on what data you need and what system you're switching to. Square's support team can provide export files in standard formats like CSV. You own the data, so there's no penalty for leaving.

Do I have to use a Square tablet, or can I use my own iPad?

You can use your own iPad (7th generation or newer) or Android tablet. You don't have to buy or rent a Square-branded device. However, if you rent hardware from Square, the tablet is usually included in the rental price.

How long does it take to get paid after a customer pays with a card?

Square deposits money into your bank account daily or weekly, depending on your settings and your bank. Most deposits arrive within one to two business days. You can check the expected deposit date in the Square Dashboard.

Can I run multiple Square Register terminals at the same location?

Yes. You can add multiple devices to the same Square account, and they all sync to the same sales record. This is useful if you have multiple checkout counters or if you want a backup terminal. Each device needs its own tablet and card reader, but they share the same cash drawer and receipt printer if you want them to.
