What an aging report shows

An accounts receivable aging report groups everything customers owe you by how long it has been outstanding. Each row is a customer, and each column is an aging bucket. The total of the report equals your receivables balance.

This report ages invoices from the due date, so the buckets show how late customers are paying. An invoice due tomorrow is current. An invoice due 45 days ago sits in 31–60.

How to read it

  • Look at the right-hand columns first. Balances over 60 days are the hardest to collect and the most likely to be written off. Know why each one is still open.
  • Check concentration. If one or two customers make up most of the past-due total, a single conversation may matter more than a hundred reminders.
  • Compare with last month. One report is a snapshot. Balances moving from 31–60 into 61–90 tell you collections is falling behind, even if the total looks steady.
  • Separate “late” from “stuck”. Many old balances are not customers refusing to pay. They are invoices rejected in an AP portal, waiting on an approver, or short-paid with a difference nobody has researched.

Aging summary and aging detail

An aging summary shows one line per customer with a total in each bucket, like the report above. An aging detail lists every open invoice with its due date and days past due. Use the summary to see where the money is, and the detail to work through it invoice by invoice.

Exporting open invoices

  • QuickBooks Online: run the A/R Aging Detail report, export it to Excel or CSV, and paste the rows here.
  • NetSuite: run the A/R Aging Detail report under Reports > Customers/Receivables and export it as CSV.
  • A spreadsheet: any sheet with a customer, an open balance, and a due date or invoice date works. Copy the rows, including the header, and paste.

Subtotal rows such as “Total Acme” and rows with no balance are skipped automatically. Credits with a negative balance reduce the bucket they fall in.

From aging to DSO

The total of this report is the receivables figure in the DSO formula. Divide it by your credit sales for the period and multiply by the days in the period, or use the DSO calculator to see how far past terms your customers pay. For the oldest balances, our payment reminder and collections email templates cover the most common reasons an invoice is stuck.

Questions

What is an accounts receivable aging report?

An accounts receivable aging report lists the money customers owe you, grouped by how long each invoice has been outstanding. Balances are usually split into current, 1–30, 31–60, 61–90, and over 90 days past due, by customer, so you can see who is paying late and how much of your receivables is at risk.

Are invoices aged from the invoice date or the due date?

Either, as long as you are consistent. Aging from the due date shows how late customers are paying, which is what collections needs. Aging from the invoice date shows how old the receivable is regardless of terms. This tool ages from the due date, and uses the invoice date plus your default terms when a due date is missing.

What are the standard aging buckets?

Current (not yet due), 1–30 days past due, 31–60, 61–90, and over 90 days. Some teams add a 91–120 bucket or split over 120, especially when they reserve for bad debt by bucket.

How often should I run an aging report?

Weekly for collections work, and at every month end for the close. Comparing the same report month over month shows whether balances are moving into older buckets.

How do I export open invoices from QuickBooks or NetSuite?

In QuickBooks Online, run the A/R Aging Detail report and export it to Excel or CSV. In NetSuite, run the A/R Aging Detail report under Reports > Customers/Receivables and export it as CSV. Paste the rows here. The tool looks for columns such as customer, invoice number, due date, and open balance.

Is my data stored?

No. The report is calculated entirely in your browser. Nothing you paste or upload is sent to Alder or stored.

Work the aging report, not just read it.

Alder goes through your aging ledger invoice by invoice, finds out why each one is late, and drafts the right follow-up for your approval. See how collections works.
