I watched the videos you have available on Youtube, but the impression I got is that ATUM is a program that you can use just to run a business that includes a webshop. My business actually has a webshop, but it is not the core part of the business. What is actually very important to me, is to have the possibily to build products and use ATUM to manage my stock. In other words, the biggest part of the products we build (campervan conversion) are actually to use as rental items and not as saleable items. How can I use ATUM with this specifications? Because it seems to me that the only way to "tell the system" that some items got out of the warehouse is through a sale, which is not always true. Sorry if it seems confusing
