What bookkeeping means on the road
Farrier bookkeeping is mostly evidence: who you billed, who paid, miles tied to business stops, and materials you can substantiate. You are building a story that survives a question, not a novel.
Invoice records are the spine
PDFs, numbering, and payment dates matter. Farrier invoice records should match bank deposits without archaeology in Camera Roll.
Mileage that matches reality
Log miles in the same system you use for stops so addresses and dates line up. See mileage & tax prep for habits that hold.
Exports your accountant actually wants
CSV or structured summaries beat screenshots. This is general farrier accounting hygiene, not legal advice — talk to a pro for your jurisdiction.
