Historically, cash registers were the only option for accepting and processing payments, but now streamlined point-of-sale systems are a serious contender for their ease of use, advanced technology and robust cash-management capabilities. The cost of POS systems can be prohibitive for those who only need the simplicity of a cash register; however, their extra features and mobility may make them essential for businesses that make sales outside of a physical storefront.

What is a cash register?

Cash registers hardly need explaining: They’re the traditional, electronic payment processing system at a countertop point of sale, with a cash drawer for storing cash and hardware to process credit card payments. Merchants can accept checks at their cash registers, too.

Every cash register has different capabilities, but on many you can calculate tax, tip and discounts, process returns and exchanges, review inventory lists, print daily sales totals, hook up an external barcode scanner (purchased separately) and track employee use.

Why you should use a cash register

Cash registers work for brick-and-mortar businesses that only need to process payments and don’t want the additional business-management capabilities that come with modern POS systems. They’re easy to track down and purchase inexpensively, too — a basic cash register at Staples or a similar office supply store can cost less than $100. You might need to separately purchase a barcode scanner and a credit card processor.

Some business owners might simply feel more comfortable using a traditional cash register, rather than opting for an all-digital solution.

Why not to use a cash register

Traditional cash registers are limited to processing payments and basic sales reporting — and even then, you’re tied to your countertop. If you sell beyond a brick-and-mortar location, or if you want the choice to, you’ll need a POS system with a portable option. Also, e-commerce businesses, or even physical businesses with a digital store, will be better off with a POS system loaded with the software to accept online payments.

In most cases, to process credit card payments with a cash register, you’ll need to open a separate merchant account through a third party. Merchant accounts are essentially an additional bank account into which payments rendered through credit and debit transactions are deposited. An all-in-one POS system, on the other hand, has a merchant account baked into the product itself.

What is a POS system?

As the name implies, a POS system first involves a POS terminal — or, the machine that processes all types of payments — but the “system” in question refers to its embedded software that can help business owners manage several aspects of the sales process (and beyond).

Depending on the POS system you use, those capabilities can include:

  • Automatic inventory updates and easily navigable inventory management.

  • Customer behavior insight.

  • Automatic sales reports and detailed sales analytics.

  • Employee tracking.

  • Integration with other apps you’re using for your business, like MailChimp, QuickBooks, Xero and Yelp.

Many POS systems also come with hardware options that allow business owners to accept and process payments beyond the countertop. For instance, Clover Flex is a handheld device that can accept and process credit card payments, which your restaurant’s waitstaff can take tableside or you can take with you on house calls, farmer’s markets, crafts fairs or anywhere else you may want to sell your goods or services.

Beyond that, most modern POS systems give business owners the option of converting their own smartphone or iPad into a POS terminal. You’ll just need to download the software onto your personal device and purchase external credit card acceptance hardware that you can plug into your device as you would a headphone jack.

Whether you choose this option or a full POS register, your POS system will be able to accept all types of credit, including magstripe, chip and NFC cards, along with other tender like cash, checks and gift cards.

The payment process itself is simple for both you and your customer. Modern POS systems offer your customer the choice of including a pre-calculated tip and whether to receive a print or digital receipt, all on an intuitive interface.

Why you should use a POS system

There are many reasons to consider using a POS system. Not only can you easily accept and process all types of payments, but with an all-in-one payment processing system you’re also taking advantage of software that can help you manage all aspects of your business more efficiently.

If your POS system integrates with your accounting software, for instance, sales data from your POS system will automatically transfer over to your books. Most POS systems automatically capture valuable customer data, so you’ll be better able to market to your audience. Some systems even enable automatic, next-day deposits into your bank account, and with many you can automatically track employee clock-in/clock-out times and their sales performances.

All of the above are just a few of the processes your POS system is capable of. Ultimately, a POS system is a more modern, efficient and flexible method of processing payments at the point of sale, wherever that may be — and of running your business overall. Plus, you likely won’t need to contend with the same technical difficulties you may encounter with your analog cash register, as POS system software updates automatically. But if you do have a problem with your hardware or software, you can always contact your POS company’s customer support at no extra cost.

Why not to use a POS system

For all of its positives, there are a few reasons why you may not want to use a POS system.

For one, all-in-one POS systems can become pricey. While you can purchase a basic cash register for around $100, a POS register with loads of features, like the Square Register, can cost you upward of $1,000. (If you don’t need a full register, POS systems offer simpler and less expensive hardware options as well.)

Remember, though, that depending on your cash register, you might need to purchase additional hardware, like a credit card reader, a barcode scanner and a cash drawer. And with both tools, you’ll need to pay a processing fee for every transaction — whether that fee goes to the POS system company or your merchant account company.

Finally, you might not want to opt for a POS system if you’re not interested in, or comfortable with, investing in a tech-forward option with all the bells and whistles. Again, if your business only needs the ability to accept and process payments, the additional capabilities that a POS offers might end up being burdensome.
