As answered by people managing Unitlo and Opalstack.
Unitlo's answer
Unitlo turns expense tracking into a 10-second habit: snap a receipt → OCR extracts vendor and amount → AI suggests the right IRS category. The AI layer also flags anomalies, separates capital improvements from repairs, and surfaces missed deductions before April. The live CPA portal lets your accountant review, approve, reject, or annotate transactions in real time - no account needed on their end. At tax time, Unitlo fills the actual IRS Schedule E and Form 4562 PDF templates with your year's data, every receipt attached, ready to submit.
Unitlo's answer
Most rental software falls into two camps: spreadsheets (don't scale, lose receipts, manual everything) and enterprise property-management platforms built for 50+ unit portfolios (overkill for an owner, expensive, designed for property managers). Unitlo sits exactly in the gap - small enough to fit a 1-5 property landlord's actual workflow, sophisticated enough to produce IRS-line-mapped tax exports automatically. The 10-second receipt-capture habit is the differentiator: most other tools take 60+ seconds of manual entry per expense, which is why most landlords abandon them by March. Unitlo makes the habit small enough to actually stick. At tax time, Unitlo fills the actual IRS Schedule E and Form 4562 PDF templates with your year's data - not a generic "tax-ready report" you still have to translate to the form.
Unitlo's answer
US small landlords with 1-5 rental properties - the segment that owns roughly two-thirds of US single-family rentals but is poorly served by software. Most are first- or second-year landlords still figuring out the tax side. They're not real-estate professionals; they have day jobs and rentals on the side. Unitlo is built for the moment between paying a contractor and reconciling on a Sunday - the gap where most documentation gets lost. Pro and AI tiers extend to landlords scaling toward 10+ properties or running multiple portfolios.
Unitlo's answer
Unitlo was built after extensive interviews with US small landlords. One pattern came up over and over: first year as a landlord, sit down at tax time with a shoebox of receipts, a notes app of dollar amounts with no context, and a folder of half-saved PDFs. By April, the CPA has reconstructed about $3,200 in deductions from bank statements and best guesses. The spending was real - the records just didn't survive the gap between paying the plumber and reconciling on a Sunday. Unitlo was built to close that gap with a single 10-second habit that fits between meetings and after work.
