Receivables aging report (days since invoice date)

Paste unpaid invoices and the tool sorts them into four buckets by the number of days from the invoice date to the as-of date. Amounts are used exactly as you enter them (tax-inclusive or not). It counts days since the invoice date, not days past the due date.

One line per invoice: customer, invoice date (YYYY-MM-DD), unpaid amount (comma or tab separated; lines starting with # are ignored).

This tool calculates inside your browser only and sends nothing anywhere. Results are your inputs multiplied by the assumptions shown on screen. They are not accounting, tax, payroll or legal advice; your own staff and advisers make the final call.
