As answered by people managing Doortrackr and Code Effects.
Doortrackr's answer
Doortrackr is the only income and expense tracker built specifically for small landlords — not QuickBooks, not a property-management suite trying to do everything. The AI receipt scanner fills in vendor, amount, and date from a photo; every expense maps to a real IRS Schedule E category; and job-level organization makes repair-vs-capital decisions easy. Plus at $6.99/mo flat, every feature is unlocked on every tier — no gates, no per-scan caps, no bank-linking required.
Doortrackr's answer
Competitors gate the basics: Stessa caps receipt scans at 5/month and paywalls Schedule E at $28/mo, Landlord Studio paywalls both plus a per-unit escalator, and Baselane requires banking lock-in for the free tier. Doortrackr is $6.99/mo flat with unlimited receipts and Schedule E reports on every tier — and a genuinely free plan for one property. It's the honest-price option built for landlords with 1–20 units.
Doortrackr's answer
Small DIY landlords and real estate investors self-managing 1–20 rental units — often with a day job, a spreadsheet they’re lying to themselves about, and a shoebox of receipts. Plus the CPAs and bookkeepers who serve them.
Doortrackr's answer
Doortrackr was founded in 2025 by Sam Tato, a landlord who spent years stuffing receipts in his wallet, filing tax extensions every August, and paying CPA rates for what was really receipt sorting. He built the tool he wished existed: snap a receipt in 30 seconds, stay organized by property and job all year, and walk into tax season with a Schedule E report already done.
Doortrackr's answer
Cross-platform web, iOS, and Android apps backed by Supabase for real-time sync, with AI-powered receipt analysis for vendor, amount, and date extraction.
