What your client sees
Clients don’t need to learn your system, so there isn’t one to learn. They see what’s missing, in plain words, and what they’ve already sent.
“I don’t have this” matters as much as “I’ve sent this”. A lot of chasing is asking for things that don’t exist this month.
This sample shares its data with the board, so a client’s answer shows up there straight away. Open both in separate tabs to watch it happen.
Sample only. No file is uploaded and nobody is told. The buttons update this browser’s sample board.
