Several years ago I used an app called goodbudget, based on envelope bugeting. In my mind's eye, there will be modules, even maybe nuget packages like financial accounting domain and invoicing libraries. Not sure how that all works yet. But I have more specific app dreams and everything always comes back to needing an accounting module. I have options of MAUI, bolero, fable, uno, and others too. I am not ready to decide totally on one yet, but I have been most interested in bolero. Do you have anything started yet (GitHub)? You can email me using my name and the domain of the blog if you care to share anything privately.
