How do I read the Ageing tab on What we owe?

It is Xero's aged payables for every organisation as of the date chosen, so it agrees with Xero on that date. The bands are Xero's, counted from the due date: Current, 1–30, 31–60, 61–90 and 90+ days, each with its share. Narrow to organisations, projects or live / closed projects, search a supplier, and group by nothing, by Xero organisation or by supplier. Excel (with live formulas), CSV, PDF and Email report take the table as filtered.
