Visualize the advantages and disadvantages of using a traditional point of sale system compared to our application with cloud storage, before you buy.
While it is true that buying a traditional point of sale system is just one payment. On many occasions you have to be making improvements to the system either due to new government guidelines or improvements that the restaurateur himself needs, which implies paying a monthly fee for said improvements to the company where it was purchased. It also implies the purchase of the system and one or two computers to be able to work it. With the disadvantage that if the computers break or fail or are stolen from the store, all the information is lost. With a traditional point of sale system you will only be able to sell to customers who come to the store and you will not be able to sell online to hundreds of other customers. Just like modern apps do.
