About
About Field Ledger
Field Ledger is a contemporaneous record-keeping tool for US-based short-term rental hosts. It exists for one reason: for STR hosts pursuing the §469 STR-loophole strategy, the records the IRS expects get reconstructed in January instead of captured as the work happens.
The founder
Field Ledger is built by Petros Kapakos, a software engineer with 20 years of building business and financial systems for places that can't afford to get the data wrong — past American Express and Amazon, currently a senior engineering manager at a major cloud platform.
The product exists because no existing tool captured the records the §469 STR-loophole strategy requires — material participation hours (for §1.469-5T), mileage, per-property expense logging, and per-stay records (for the §1.469-1T(e)(3)(ii) average-stay test) — at the rigor a CPA would actually trust. Petros needed one for his own properties; now it's a product.
The structured CSV export, the suggested categorization, the per-property tracking — all of it is engineered to the standard you'd want from someone whose day job is building production systems at scale.

Product principles
-
Contemporaneous, not reconstructed. Entries logged as the work happens are contemporaneous and organized. Logs rebuilt in January are neither. Field Ledger is built around this principle.
-
Two capture modes, structured records either way. Log participation activities in plain language — the rule-based parser structures them. Capture trips, mileage, and expenses with quick guided forms so nothing is guessed. Each expense arrives with a suggested category for your CPA to review and confirm. Clean inputs, not interpretive guesswork.
-
US-only, by design. The §469 STR exception is a US tax-code provision. Field Ledger does not attempt to serve other jurisdictions. Regulatory clarity matters.
-
Records, not advice. Field Ledger captures what you did. It does not tell you whether you qualify for the §469 STR exception, whether to claim a deduction, or how to structure your tax position. That's your CPA's job.
-
Privacy-respecting analytics. The marketing site uses Plausible Analytics, which is cookieless and IP-anonymized. The app uses its own server-side event tracking. We do not share usage data with third parties.
