Hi,
For the most part I agree with
@durbancic. Today, Having a POS is a good option.
BUT,
If you’re the one running the show daily and not having some manager replacing you, and if your store does not offer delivery, then you don’t necessarily need a POS even if you do over 15k/week!
I have many customers that have not invested in a POS system as they don’t think they need it.
But they are there day by day, them wives & kids!
However, where kids are taking over the family business or younger people in general start their own business, they do get involved with technology (POS, online orders, apps, etc) in order to grow their business, be competitive and potentially reach to more customers by offering more options and as a result they end up being busier in many cases but making less profit than before!
Sad but true!
Of course if you run 2 or more stores, have delivery or have a manager in place, the need for a POS System goes without saying since you’ll need something to help managing your business as much as you can.
