FAQ

What is an accounts receivable aging report?
It groups unpaid invoices by how many days past their due date they are, usually current, 1-30, 31-60, 61-90 and over 90 days, so you can see how much is late and whom to chase first.
Do you age from the invoice date or the due date?
You choose. Due date shows days overdue. Invoice date plus your terms (for example 30) works out the due date for you.
Is my invoice data uploaded or saved?
No. Everything runs in this tab; nothing is sent or stored. Reload and it is gone.
What format should I paste?
One invoice per line: client, amount, due date (YYYY-MM-DD or DD/MM/YYYY). Commas, tabs or semicolons work, so paste straight from Excel or Sheets. A header row is ignored.
Which invoices should I chase first?
Usually the largest amounts in the oldest buckets. Over-90-day invoices need a firm reminder (try our invoice reminder generator). This is an organiser, not accounting or legal advice.
