What is an iPad POS System?

An iPad POS system is an all-in-one POS solution designed for Apple’s iPad. that comprises a credit card reader, barcode scanner, payment terminal, and receipt printer thanks to peripheral devices and software add-ons. This type of POS system is convenient and easy to use, but it’s also able to keep all relevant data in the cloud. Plus, the system will help you manage virtually every aspect of your business, including inventory, ordering, accounting, and more.

Why iPad, you may ask? From my experience, iPads boast an unmatched price/quality ratio. They’re durable, easy to update and operate, and not too expensive to maintain. When it comes to iPad point-of-sale software, I like its typically feature-rich structure and intuitive interface.

Comparing the Best iPad POS Systems | Buyer’s Guide

I know that you probably want a universal solution that could take care of all the managerial aspects of running your business. Truth is, there isn’t a perfect POS solution simply because no two businesses have the exact same requirements. This means that you’ll need to find THE one that suits your organization to the fullest extent. Thus, the specific set of requirements and preferences you should stick to should be exclusively structured to fit your company. However there’s a short list of must-have features typical of the best iPad POS system:

  • Integrations: Except for integrating with your iPad, a flexible iPad based POS system should be compatible with all kinds of other third-party hardware and software solutions.
  • Inventory management: The best iPad POS systems always boast an extended inventory management and monitoring toolset, allowing you to keep track of stock quantities and receive notifications and alerts related to your inventory.
  • Multichannel support: In case you’re running multiple locations or you’re running both an online and an offline operation, your POS system should be able to sync all dynamic data and sales history across all sales channels.
  • Price/features ratio: To make the most of your investment, you need to pick the iPad POS system that has all the features you could ever need. Buying the one that’s referred to as a bestselling product is not a solution, as it may lack important perks that could be crucial for your development. Of course, you must not exceed your budget for the sake of having extra features you won’t use. The golden middle is what you should strive for.

There are dozens of other important features you should probably look for, but these are the ones that will make the biggest difference for your business. When you compare the times before you had an iPad POS system as part of your arsenal and the period after that, you’ll realize you’ve been missing out on a lot of goodies.

iPad POS System Features | The Checklist

When you start looking for an iPad POS system for small business like your own organization, you will find many options to choose from. I know that you’d be wondering how to pick the right POS solution for your needs. To help you choose wisely, I tried to pinpoint some important things to consider before making such an investment

Costs. The cost of an iPad POS system is important. While you should not go with a system simply because it’s free (it might not serve your business well), the prices of some of the best iPad POS systems can vary a lot, depending on the features you need, the peripherals, the transaction costs, and more. You need to avoid the most expensive ones and find a solution that offers a good balance between price, additional costs, and the value the system will bring to your business. A good POS system will provide the best return on investment and help you earn your money back many times over a short period of time, thanks to the streamlined processes and the higher customer satisfaction. 

Features.  Always look at what features are offered and decide which are the most critical to your business, depending on your niche, business model, and other specifics. Just because a system has all the bells and whistles doesn’t mean it will improve your business to the extent you want. You want a POS system that has the right features for your business, not just one with a long list of perks that you will never use. Look through all the available features every POS vendor offers and determine how many of them would be handy for your organization. you would use. 

Compatibility. If you already use a particular platform or you like to work with specific apps, it may be a good idea to find a POS system that will integrate with the rest of your existing setup. This idea also pertains to any apps that you use to run the business. For companies that are just starting and do not have their own form, choosing a POS system first is trickier, but it should still be integrable with third-party software and hardware in case you want to add them later. 

Ease of use. You should also consider how easy your new iPad POS system needs to use. Choosing a system that is hard for your customers to use and your employees to learn is a huge no-no. Most iPad POS systems are simple to operate, but it’s possible that some would never be a good fit for your organization. A good choice here is to try out a few options if they come with a trial period, and see which one seems to match your expectations the best. 

Best iPad POS Systems 

The popularity of iPads as a client servicing tool has resulted in a lot of competition in the iPad POS system niche. I know It can be tough to find the best solution for your company.

Based on my research, the best iPad POS system for restaurants is TouchBistro POS. It has restaurant-specific features that set it apart, not to mention its vast array of features, affordable price list, and reliable customer support. On the other hand, the best iPad POS system for retailers is Square POS by far.
