Where do I see every sales invoice across all our companies?

Accounts → Sales Invoices (/accounts/sales): every sales invoice and credit note across all Xero organisations. Total Invoiced (after credit notes), Paid, Outstanding and Overdue for the period and filters in view. Quick picks: last 12 months, this month, last month, this year, or your own dates. Filter by organisations, projects and their status, statuses and customers; group by customer, month, status, organisation or project with a subtotal per band. CSV, PDF and email take the list as filtered. Nothing on this page writes to Xero.
