FieldInvoice AI
A hackathon build that turns contractors' messy field notes into verified invoices with Stripe payment links — spec'd properly: PRD, BDD, and ADRs across 19 modules.
Paste the mess a contractor actually writes and the LLM extracts the line items — descriptions, quantities, amounts — into a draft invoice, one take, no template shuffle.
Extracted line items land in a review step before anything goes out — the model does the tedious reading, the worker keeps the signature, because billing errors cost trust.
Change a quantity or an amount and the totals recalculate on the spot — the review step is a working editor, not a confirmation dialog.
The finished invoice exports with a Stripe payment link attached — the gap between finished field work and getting paid closes in one flow.
Field workers write notes, not invoices. One flow closes the gap between finished work and getting paid.
The LLM proposes, the human approves — extracted line items are reviewed before an invoice is issued.
Even at hackathon speed: a PRD, BDD scenarios and ADRs across 19 modules. The spec survives the demo.
