Read the AP and AR aging reports

Two reports show what's outstanding, bucketed by how overdue it is:

• AR Aging (Ledger › Reports › AR Aging): unpaid customer invoices, who owes you and for how long.
• AP Aging (Ledger › Reports › AP Aging): unpaid supplier bills, what you owe and for how long.

Both use the buckets Current · 1-30 Days · 31-60 Days · 61-90 Days · 90+ Days, with the 90+ column highlighted when there's anything in it. Download either as CSV or PDF. On AP Aging, Group by vendor rolls bills up by supplier once your bills are vendor-linked, and foreign-currency bills are subtotalled per currency under one Total Outstanding.

Both reports read as of today. AR Aging lists sent, viewed, and overdue invoices (paid and credit-note rows drop off); AP Aging lists your approved and matched bills.

Bills that aren't on AP Aging

AP Aging answers one question: what do you still owe your suppliers? So it leaves out bills where the supplier has already been paid.

• Someone paid it out of their own pocket. If a bill is marked as paid by you personally or by a team member, the supplier got their money at the till. What's outstanding is the reimbursement to that person, so the bill is not a supplier payable and never shows here. Find it under Reimbursements on Ledger › Expenses, grouped by person with that person's running balance.
• A receipt. A receipt is proof of a payment you already made, so it's paid at capture.
• You paid it on a business card and the bank line hasn't arrived yet. This one is only waiting on reconciliation, so it stays inside your Accounts Payable balance even though aging leaves it out.

The Vendors page follows the same rule. A supplier's Unpaid and Overdue figures count only what you still owe that supplier, while spend counts every bill, however it was paid. Expand a vendor's row and any of the above appear under Not in aging with the reason, so a bill never disappears from the supplier you spent the money with.
