BorderBird is rental accounting built for cross-border landlords — non-residents who own Canadian rental property (CRA Part XIII / NR4 / NR6 / Section 216) and Canadians who own US rentals (IRS Schedule E).

Key features: - Email-forwarding reconciliation: forward your Interac e-Transfer or Zelle rent-payment emails to a private address and BorderBird auto-matches each one to the right lease — no inbox connection, no bank screen-scraping. - CRA Part XIII / NR4 withholding (25% of gross, or net under an approved NR6) calculated automatically and proposed for human approval before anything posts. - Dual-currency P&L (CAD + USD on Bank of Canada rates) plus Schedule E and T776-ready CSV exports. - AI assistant drafts the bookkeeping (withholding, NR4, expense categorization) under a human approval gate.
