Thank you for sharing this! The part of this problem that I’ve found most challenging over time is keeping quantities up to date. I wonder about a function where you could say “I built 25 of these modules” and it would deduct the quantities for individual parts accordingly (optionally adding an extra percentage for the 0402s you dropped on the floor) Or, while I’m dreaming, a feature that parses a DigiKey/mouser/etc. order (or reads the barcodes on the bags!) and updates quantities for you.

Would also be curious about how best to support different storage approaches, like reels on a shelf etc.

We seem to think in similar tracks! I do have the exact features you describe already. Each BOM that I add can then be searched for and its parts deducted in batches (of for example 25 times the amount of parts are needed per module).

And a BOM can be imported from a csv file exported from a Digikey/mouser shopping cart. Although now that you mention it, re-stocking from such a csv would be a really nice addition.
