Every business mile, logged the day it happened.
Tell Grain AI about a trip, "45 miles to the Henderson kitchen and back", and the mileage gets logged with the right job, the right date, and the right purpose. The iPhone app adds live GPS trip tracking that keeps recording in the background.
How mileage logging works today
Open Grain AI chat (typed or voice). Describe the trip in plain language: from-where, to-where, miles, and which job it was for. The AI logs the trip with the standard IRS-mileage fields and links it to the right job's P&L.
Trips are editable after the fact, fix the date, attach a different job, adjust the miles. Every trip carries a per-mile rate so the deduction value rolls up cleanly at year-end.
- Log a trip by talking or typing in Grain AI chat, same flow as receipt logging.
- Auto-extracted: from/to, miles, date, purpose.
- Linked to a job, feeds per-job P&L.
- IRS-standard fields for tax-deduction reporting.
- Editable after the fact for typo fixes or job re-attribution.
GPS trip tracking in the iPhone app
GPS trip tracking is live in the iPhone app. Tap Start Trip before you head out, and the app records the GPS route and the miles in the background, so there's nothing to touch while you drive. Once you're parked, tap End Trip; the app suggests the job you stopped at, and you confirm which job the trip was for.
Trip tracking is the difference between "I think I drove ~40 miles to that job" and "I drove 38.7 miles to that job, here's the route." Chat-based logging still covers any trip you didn't track; it records the same data, it just asks you to type or talk it.
- Start Trip and End Trip, with recording that keeps going in the background.
- GPS-route capture for the audit trail.
- At the end, pick the job the trip was for, with the nearest job suggested.
- Tracked trips and chat-logged trips land in the same mileage log; tracked trips also keep the GPS route.
Why log mileage at all
Vehicle mileage is one of the largest deductions a one-truck operation has. The current IRS standard mileage rate covers fuel, maintenance, depreciation, and insurance, and an honest trade truck logs real deductible miles every year.
The hard part isn't claiming the deduction; it's having a record that holds up if the IRS asks. Logging trips at the time they happen, instead of guessing from memory in March, is the difference between a defensible deduction and a creative reconstruction.
