Codex to review a year of receipts before tax export
Matthew Vroom used Codex to clean up a year's business expense records before tax preparation. His starting folder contained unlabeled PDFs, receipt photos and emails, and it was incomplete. The job was both organizing the evidence and identifying what might be missing.

Reported by Matthew VroomHow the agent did it
- Point Codex at the mixed receipts folder and process supporting statements.

- Review Schedule C and supporting exports before using tax preparation software.
Where a person stepped in
Vroom demonstrated source inspection and review tabs; final tax filing and correctness of every category were not confirmed.
Matthew Vroom used Codex to clean up a year's business expense records before tax preparation. His starting folder contained unlabeled PDFs, receipt photos and emails, and it was incomplete. The job was both organizing the evidence and identifying what might be missing.
He pointed Codex at the folder and had it parse receipts, rename files, build a ledger and cross reference statement data. After about twenty five to thirty minutes, he demonstrated a local dashboard. Receipt views exposed the source document, vendor, amount and extracted details instead of hiding the evidence behind a total.
A review tab separated duplicate candidates, unsuccessful parsing and uncertain expense records. Reports included a Schedule C entry summary intended for TurboTax, with supporting expense details. Vroom described these as preparation outputs; the video does not confirm that a return was filed or that every proposed category was correct.
The linked published prompt is specifically a ReceiptSweep demo workflow. It keeps original source files unchanged, reuses a designated runtime and asks for conservative review flags instead of weak vendor guesses. That distinction matters when copying the prompt: it is a documented demo instruction, not a promise that an unfamiliar receipts folder can be accepted without inspecting its review queue.
