A good start is by compiling a list of needs. If you need a POS for the hospitality industry, such as in a restaurant, there are a few must-have items. The same is true for POS retailers as used in clothing boutiques.
List your needs based on various aspects of your business such as inventory, accounts payable, accounts receivable, reporting, and more. When you have everything on paper, it will be easier for you to decide later. You can also purchase the best pos inventory system via https://dearsystems.com/point-of-sale/.

The basic mistake entrepreneurs make is basing their decisions on existing hardware. Remember to pick your POS software first, not the hardware.
You need to define your business details based on your list of requirements and then understand how the POS software can meet your specific needs.
You can then consider whether the existing hardware can be used with the POS software system of your choice.
You may be tempted to buy a new cash register or computer, but you may deplore that POS systems are very different in terms of their hardware requirements.
So, if you buy hardware now without analyzing your business needs, you are shooting yourself in the foot and limiting your options in choosing the right POS software.
Then you need to carefully check the POS provider. Ask for recommendations or find a reputable online company.
If you already have many potential suppliers, contact them and ask relevant questions such as the number of their customers, how long they have been in business, and whether they would like to make a professional recommendation.
