PureBill turns a work photo into an evidence-backed invoice draft. I'm a computer repair tech in the field, and today documen ting a job means trusting my memory at billing time — clients can't see what I saw, and I can't prove what I found. PureBill fixe s that: I photograph the finished work, SAM 3.1 segments what's in frame, a vision model describes it with explicit uncertainties , and a bookkeeping agent drafts catalog-linked invoice lines for my review before anything posts. The demo runs a staged intake-fan replacement (HB-1042): 7 items boxed and overlay-verified, 4 lines proposed, 3 specs the mo del honestly refused, posted as sandbox invoice 1038 ($41.00). Nothing reaches real books without review; production was never to uched. For techs like me, every charge traces to a photo, a box, and a hash — billing my clients gets easier, and transparent by construction.
