For a money app, how would you distinguish a missing cash input from a confirmed zero?
I build Monni, and I'm reviewing an edge case for manual money inputs: someone has entered upcoming bills, but hasn't entered cash yet. That's not the same as confirming a cash balance of zero.
My proposed approach is to name the missing input next to the estimate and offer one specific correction, rather than use a reassuring headline number or a generic 'finish setup' warning. The alternative is to withhold the estimate until cash is confirmed, but that also hides the reason the input matters. This is a design question, not a claim that either new behavior has shipped.
If you've built a tool with incomplete user-entered data, would you show a visibly provisional result, or block the result until that input is confirmed? I'd especially value examples where users understood the difference.
