Reports
The AR aging report
What is counted, and what is deliberately left out.
Outstanding invoices, bucketed by how overdue they are: current, 1–30, 31–60, 61–90 and 90+ days. Empty buckets are hidden.
Only sent, partly paid and overdue invoices appear. Drafts were never sent and voided invoices were never owed, so including either would overstate what you are waiting on.
On a partly paid invoice the figure shown is what is still owed, not the original face value.
The report is firm-wide. Every row links straight through to the invoice, so you can go from "this is 45 days late" to following it up without a second search.
