The ease of customization in terms or products can create any number desired, from 1-4 per item for example! This tool was used previously by another entity that went out business so I had no real idea what kind if support they would give me as far as assistance with this program goes; but it has been amazing!! We have not really noticed much lag time when using these tools, all items are shown right away at once which makes sense since there aren't many selections being made one after anoth I like how easy it was for me to use. The customer service they provide is great! They've been there when I needed help. They are very knowledgeable of this program. I do not have any complaints at this time, but if I did I would be sure that I let them know and they would work with me. This is a great tool for my business. I am able to keep track of inventory, customers, employee data, etc. in one place. It's great to see all this information in one spot.
