Picas is very simple to use. The data entry process for inputting information into each product/inventory item is also extremely easy. Nothing really. I am not sure that there are any features that I do not like. There are too many benefits in using Picas, they have been able to solve so many problems. Picas keeps our inventory levels down, allowing us more time for processing orders. I like that you can manage everything related to production in one place. It is easy to use and user-friendly, so that even beginners will be able to use it.The price could have been lower, but this does not seem to bother us. We're solving our issues with inventory control and customer information.
