You quoted $4,800. The job cost $5,140. That’s not a mindset problem — it’s a missing cost sheet.

Job Cost Desk is a one-file browser desk for US 1099 / service operators. Log quoted price, labor hours, materials, and subs. It shows actual, variance, and margin on quote. A Python CLI does the same math from a CSV. Nothing is uploaded.

WHAT YOU GET
• job-cost-desk.html — runs offline
• jobcost.py + sample-job.csv (Python 3.10+, no pip)
• example-output.md from that sample (Oak St changeout: quoted $4,800.00, actual $5,140.00, variance −$340.00)
• Personal or commercial license

HOW IT WORKS

1. Open the HTML file
2. Load the sample or type a job
3. Add labor / material / sub lines
4. Print the report or export CSV

NOT THIS
Educational job-costing arithmetic. Not licensed accounting, not a 1099-NEC filer, not a promise any job will be profitable. 365-day download access (you keep files you downloaded). 7-day refund if the HTML will not run or jobcost.py errors on sample-job.csv.
