How does it handle payments, payable/receivable etc (if applicable)? I have found that in these cases often times the software handles the operations well, but the business logic is still tied up in legacy POS and things like this which makes the software more of a nice to have than a "I'll just do it the old way". I'd also be curious about the UX (am a designer)
Product integrated with 4 major accounting systems, so it was more like frontend for those legacy stuff. Major thing was warehouse/logistics system which was my own.
In wine business thats quite complex thing: you might want to sell bulk wine, you might blend different stock together or bottle one lot in multiple times. There is strict requirements by govt about declaration of those thing. Each country qlso have different requirements and reporting formats.
