I'd like to share with you something I've been developing for quite a while now.
It's called BOMER, a Parts Inventory and BOM Management software for electronics.
It is more than a simple parts management tool. It allows you to manage Projects (BOMs) and Orders and get real-time pricing information. This feature alone is extremely useful to get an idea what the total/unit cost for a 10,100,1000 units run would be and, for that same reason, to quickly quote projects (in case you, like me, create hardware for a living and need to send quotations often).
It will have a paid version but it will also have a FREE one, forever. It's now in BETA, full featured and with extended limits.
If you, like me, struggle on keeping your inventory and projects organized, give it a try! Let me know what you think and how you'd like to see it improved.
