A two-week self-directed UX challenge with another designer, and no access to BILL's internal systems. BILL automates accounts payable, but its approval flow leaves users guessing about where an invoice sits, who's holding it up, and what needs attention first. I rebuilt seven core screens and tested the prototype with six users in Maze. Every task got completed, but the test surfaced a friction problem I didn't expect, and that's where I learned the most.
