One product, three jobs
Work out the yield. Work out the tax. Keep the rent roll.
Every payment against the tenancy it came from
Rent due, rent received, voids and arrears, per tenancy and per property, so the question the accountant asks in January has an answer that is not a bank statement and a highlighter.
The property pages, ready before the deadline
Income, allowable expenses and finance costs totalled the way the return asks for them, exported for your accountant, and pushed into QuickBooks Online or Xero if that is where your books live.
The tools, free and open
Free to use. No account, no card, no trial clock.
