What is the best solution for your business?

The best solution varies by your business needs, sizes, and technological resources. The best open source POS is the one that possesses enough functions to help you deal effectively with your common business issues without exorbitant expenses. Besides, most open source point of sale systems can indeed be customized to meet specific requirements. However, it’s worth considering whether you plan to scale your business in the future and whether you need professional support to modify the POS as you want.
