A Comprehensive Overview of Modern POS Systems
Let’s face it: successfully running a business involves juggling a lot of moving parts. You’ve got to keep track of sales, manage inventory, schedule staff, build customer loyalty—the list goes on. In the midst of all this, you still want your customers to have a fast and easy checkout experience. That’s where Point-of-Sale (POS) systems really shine.
Gone are the days when a POS was just a cash register and receipt printer. Today’s POS technology can become the central hub for all your business operations. And here at Durango Merchant Services, we know that choosing the right system can feel a bit overwhelming. With so many options out there—from free mobile apps to advanced enterprise setups—how do you decide?
Don’t worry, we’ve got you covered. In this blog post, we’ll walk you through the fundamentals of modern POS solutions, the must-have features to consider, the typical pricing models, and then we’ll talk about the top options for businesses in retail, restaurants, salons/spas, and small local shops. Our goal is to help you see how a well-chosen POS can make your life easier (and your customers happier), all while working hand-in-hand with a dependable merchant services provider.
What Is a POS System & How Does It Work?
A Point-of-Sale (POS) system is basically the software and hardware combination that handles your checkout process, accepts payments, and tracks your sales. But it’s also so much more than that these days.
Breaking It Down:
Sales & Payment Processing
The most obvious role of a POS is to ring up items and take payments. Think of it as your digital (or touchscreen) cash register. Once you add products or services to the ticket, the POS calculates totals, taxes, and discounts, and then processes the payment. It could be cash, card, contactless payment like Apple Pay, or even gift cards.Data & Record-Keeping
Behind the scenes, your POS is creating a treasure trove of data for you. Every transaction is recorded, so you can see how much you sold in a day, which products moved fastest, and what times were busiest. This data is gold for making smarter business decisions.Inventory Tracking
When a sale goes through, the POS automatically updates inventory. That way, you don’t have to manually count how many blue T-shirts are left at the end of each day. For restaurants, this might mean ingredients are updated in real time. For salons, it might track the retail products like shampoos or hair dyes.Integrations with Payment Processors
Modern POS systems typically connect directly with a payment processor, such as Durango Merchant Services, to ensure secure, fast, and reliable transactions. This also means you can negotiate or maintain more favorable transaction rates, or add features like recurring billing if needed.Reporting & Analytics
Want a better look at your daily revenue or your best-selling items? Curious which staff member is hitting the highest sales? A good POS will generate detailed reports so you can answer these questions in one click.Customer Relationship Management (CRM)
Many POS platforms also include tools to capture customer data, build loyalty programs, and segment your audience for marketing. So now, you’re not only taking orders—you’re building relationships that last.
Essentially, your POS system can be the “brain” of your operation. It ties together important functions and simplifies daily processes so you have more time for the big-picture stuff.
Key Features and Functionalities to Look For
Not all POS systems are created equal, so it helps to have a checklist of “must-have” features. Depending on your type of business, some of these will be more important than others. Let’s go through a few common ones.
Intuitive Interface & User-Friendliness
If the interface is clunky, your staff might dread using it—and that can slow down service. Look for a system with clear menus, easy-to-navigate product catalogs, and minimal steps in the checkout flow.Inventory Management
Ideally, your POS should automatically adjust inventory each time you sell something. For businesses with large product lists, advanced features like low-stock alerts or purchase-order generation can be a huge plus.Reporting & Analytics
In many ways, reporting is the biggest advantage of moving beyond a basic cash register. You can see sales trends, identify peak hours, analyze profit margins, and even compare sales across multiple locations if you have a growing business.Employee Permissions & Time Tracking
Do you need staff to clock in and out? Do you want only managers to issue refunds or discounts? Check whether your POS supports different permission levels and built-in staff management tools.Customer Management & Loyalty Programs
If you want to implement loyalty points, membership rewards, or store credit, it’s helpful to have a POS that supports these without complicated workarounds. Some systems let you capture emails or phone numbers at checkout, then build targeted marketing campaigns.Offline Mode
If you’re in an area where the internet can drop occasionally, you’ll want a POS that can still function offline and sync the data once you’re back online. This is especially critical for restaurants during busy hours or retail events like holiday shopping rushes.Hardware Compatibility
Will you use iPads, Android tablets, or dedicated touchscreen terminals? Do you need a barcode scanner, receipt printer, or cash drawer? Make sure the POS system works with the hardware setup you prefer (or plan to invest in).Cloud-Based vs. On-Premise
Cloud-based POS systems are very popular now because they offer automatic updates, remote access to data, and often integrate easily with other apps. On-premise solutions can be more stable if your internet is unreliable, but you’ll likely be responsible for backups, upgrades, and server maintenance.Industry-Specific Capabilities
Restaurant owners may need menu modifiers and kitchen printer integration. Salons need robust appointment scheduling. Retail shops often want barcoding and label printing. Make sure the POS you pick is known to excel in your specific vertical.
Common POS Pricing Models
Before you sign up, it’s crucial to understand how pricing works. It’s not just the monthly subscription; you’ll likely also pay for hardware, payment processing, and possibly other add-ons.
Monthly Software Subscription (SaaS)
Most modern POS providers use a subscription-based model (like $0 to $100+ per month). You might see different tiers—Basic, Pro, Enterprise—each with its own set of features. Some providers (like Square) even offer a no-monthly-fee plan for basic functionality.Payment Processing Fees
If the POS requires its own payment processor, you’ll pay their transaction rates (e.g., 2.6% + 10¢ per swipe). If you can integrate your own merchant account, you might pay a separate monthly fee but get better transaction rates through a service like Durango Merchant Services. Make sure to compare both the per-transaction costs and any monthly or annual fees.Hardware Costs
Depending on the system, you might buy or lease terminals, tablets, scanners, cash drawers, and more. Sometimes providers offer “starter kits” with everything you need. Others expect you to bring your own devices. Watch out for hidden costs like proprietary hardware that locks you into a single vendor.Add-On Features & Integrations
Loyalty, gift cards, advanced analytics, e-commerce modules—these can all carry additional monthly or per-transaction fees. Try to map out what you’ll truly need so you’re not caught off guard.One-Time Setup or Installation Fees
Some companies charge a one-time onboarding or training fee. However, with many cloud-based systems, you can often handle the setup yourself if you’re comfortable with technology.Contract Terms & Early Termination
Some POS systems are offered on a month-to-month basis, which is great if you want flexibility. Others might give you a hardware discount in return for a multi-year agreement. If you sign a long contract, be sure you’re aware of any penalties for ending early.

Bringing It All Together with Merchant Services
Whichever POS you choose, there’s one piece of the puzzle that’s easy to overlook until you get started: merchant services. That’s the gateway that processes your customers’ payments and ensures the revenue hits your bank account. Here’s why partnering with a solid merchant services provider—like Durango Merchant Services—matters:
Payment Security & Compliance
Protecting cardholder data is a big deal. A reputable merchant services partner will help you stay PCI compliant and minimize your risk of fraudulent activity or data breaches.Better Processing Rates
If your POS platform lets you bring your own processor, you can often negotiate lower transaction fees. Even a small percentage difference can really add up if you’re doing a healthy sales volume.Customer Support & Reliability
When you’re in the weeds on a busy Saturday, the last thing you need is a payment processing glitch with no one to call. Good merchant service providers offer reliable support and can help troubleshoot issues quickly.Value-Added Features
Some merchant service providers offer extra goodies—like recurring billing, advanced fraud monitoring, or specialized solutions for high-risk businesses. Make sure the services align with your industry needs.
By choosing a POS that integrates smoothly with your merchant account, you create a seamless checkout flow for both you and your customers. The POS handles the front-end tasks (like scanning items and printing receipts), while the merchant services provider handles the secure routing of funds behind the scenes.
