I already use a spreadsheet and an accountant. Why switch?

A spreadsheet works at two properties and quietly becomes a job at five. August updates from your bank, stores every document by property and tenant, and surfaces reminders before deadlines pass, none of which a spreadsheet does on its own. It does not replace your accountant, it gives them clean, categorised records, pushed straight into Xero if that's what they use, which usually means less work at year end and a smaller bill.
