Elixir + Ash is an interesting choice for this domain. LiveView particularly shines for internal tools like this where you want the interactivity without managing a separate frontend build. Curious how the AI code generation worked with Ash specifically - the declarative nature seems like it could either help a lot (clear patterns) or confuse models that expect more explicit code.
The BOM with cost rollups is the feature that would have saved me hours in a previous project. Most small batch producers I know either overprice everything out of caution or underestimate costs because tracking ingredient pricing through recipes is tedious in spreadsheets.
But I do think the days of just having to learn, tolerate, and accept any commercial software stack for your business because it's too complex to build yourself are over. What vendors remain will have to absolutely meet users with their unique requirements and budget.
