What Is an AR Aging Report?

An Accounts Receivable (AR) Aging Report organizes every unpaid customer invoice by how long it has been outstanding. QuickBooks produces two versions:

The standard aging buckets are Current, 1–30 days past due, 31–60 days past due, 61–90 days past due, and 91+ days past due (QuickBooks labels this last column "> 90"). The date QuickBooks uses to measure age is normally the invoice due date, not the invoice date, though you can change that setting.

Management uses the aging report to answer three questions: Who owes us money? How much? How late is it? Without this report, overdue balances hide inside a lump-sum AR balance and cash flow suffers.

Running the Report in QuickBooks

1. From the Reports menu choose Customers & Receivables, then A/R Aging Summary or A/R Aging Detail.

2. Set the Report Date to the "as-of" date your manager specifies. All aging is calculated from that date.

3. Confirm the Aging interval is set to 30 days (the default matches standard buckets).

4. Click Refresh or Run Report.

5. To print, choose File › Print Report or export to PDF. Never leave a printed aging report on an unattended desk — it contains confidential customer financial data. Shred or securely file paper copies when finished.

Reading the Aging Summary

Each row is one customer. Each column is one time bucket. The far-right Total column is that customer's total open balance. The bottom Total row sums every column — that grand total must match the AR balance in your general ledger. If it does not, a data-entry error or unapplied payment exists and must be corrected before collections work begins.

A quick way to prioritize: scan the 61–90 and > 90 columns first. Accounts in those buckets carry the highest risk of becoming uncollectible.

Allowance for Doubtful Accounts

Not every old receivable will be collected. Generally Accepted Accounting Principles (GAAP) require businesses to estimate and record bad debt expense before the loss is confirmed. The credit entry goes to a contra-asset account called Allowance for Doubtful Accounts (AFDA), which reduces net AR on the balance sheet.

A common method is the percentage-of-receivables (aging) approach: apply different loss rates to each bucket based on historical experience. For example, a business might estimate that 1% of current balances, 3% of balances 1–30 days past due, 10% of balances 31–60 days past due, and so on will be uncollectible. Multiply each bucket total by its rate, sum the products, and compare to the existing AFDA balance. If the AFDA is below the required amount, record an adjusting entry to increase it.

Collections Management Principles

Effective collections is professional, persistent, and documented. Best practice follows an escalating contact sequence:

1. Friendly reminder — sent a few days after the due date; assumes an oversight.

2. First follow-up — sent around 15–30 days past due; requests payment or a payment arrangement.

3. Firm notice — sent around 31–60 days past due; states consequences (late fees, service hold).

4. Final demand / referral — sent at 61–90+ days past due; may precede referral to a collection agency or legal counsel.

Document every contact: date, method, person reached, and outcome. QuickBooks lets you log notes inside a customer record.

Writing a Professional Collections Email

A collections email must be courteous but unambiguous. Use these conventions:

Data Privacy and Security

AR data is sensitive business information. Observe these practices every session:

These habits protect the business and its customers, and they demonstrate the professional conduct employers expect from a Certified Bookkeeper.

Connecting to Your Credential Exams

QuickBooks Certified User exam objectives include running and interpreting customer reports, managing customer records, and understanding report settings — all practiced directly in this lab.

AIPB Certified Bookkeeper exam content includes adjusting entries for bad debts and the allowance method, which you practice in the analysis exercise.

Microsoft Office Specialist (Word/Outlook) competencies align with producing correctly formatted professional correspondence — exactly what the email-drafting activity develops.

Key terms8

AR Aging ReportA report that sorts unpaid customer invoices into time buckets based on how many days past due each invoice is, used to prioritize collections activity.
Aging BucketA column in an aging report representing a range of days past due — for example, Current, 1–30, 31–60, 61–90, and > 90 days.
Aging Summary vs. Aging DetailThe Aging Summary shows one total per customer per bucket; the Aging Detail lists every individual open invoice, also organized by bucket.
Allowance for Doubtful Accounts (AFDA)A contra-asset account that holds the estimated amount of accounts receivable the business does not expect to collect; it reduces net AR on the balance sheet.
Bad Debt ExpenseThe income-statement expense recognized when a business estimates or writes off receivables it cannot collect.
Percentage-of-Receivables MethodA GAAP-accepted method of estimating bad debt by applying different uncollectibility rates to each aging bucket and summing the results to determine the required AFDA balance.
Collections Escalation SequenceA structured, step-by-step process of increasingly firm customer contacts — from friendly reminder to final demand — used to recover overdue balances.
Contra-Asset AccountAn account paired with an asset account whose normal balance is opposite to the asset's, thereby reducing the asset's reported value; AFDA is a contra to Accounts Receivable.

Worked examples4

1. A company's AR Aging Summary shows: Current $12,400 | 1–30 days $3,800 | 31–60 days $2,100 | 61–90 days $950 | > 90 days $750. Total AR = $20,000. What dollar amount and percentage of total AR is past 60 days?
  1. Step 1 — Identify the buckets that are past 60 days: 61–90 days ($950) and > 90 days ($750).
  2. Step 2 — Add those two buckets: $950 + $750 = $1,700.
  3. Step 3 — Divide by total AR and multiply by 100: ($1,700 ÷ $20,000) × 100 = 8.5%.
Answer: $1,700 is past 60 days, representing 8.5% of total AR.
2. Using the same AR totals above, management applies these estimated uncollectibility rates: Current 1%, 1–30 days 3%, 31–60 days 8%, 61–90 days 20%, > 90 days 40%. What is the required Allowance for Doubtful Accounts balance?
  1. Step 1 — Multiply each bucket by its rate: Current: $12,400 × 0.01 = $124.00 | 1–30: $3,800 × 0.03 = $114.00 | 31–60: $2,100 × 0.08 = $168.00 | 61–90: $950 × 0.20 = $190.00 | > 90: $750 × 0.40 = $300.00.
  2. Step 2 — Sum all products: $124 + $114 + $168 + $190 + $300 = $896.00.
Answer: The required AFDA balance is $896.00.
3. The company's AFDA currently has a credit balance of $350. The required AFDA balance calculated above is $896. What adjusting journal entry is needed, and for how much?
  1. Step 1 — Determine the shortfall: Required balance $896 − Existing balance $350 = $546 additional allowance needed.
  2. Step 2 — Record the adjusting entry: Debit Bad Debt Expense $546; Credit Allowance for Doubtful Accounts $546.
  3. Step 3 — Confirm: After the entry, AFDA credit balance = $350 + $546 = $896, matching the required amount.
Answer: Debit Bad Debt Expense $546; Credit Allowance for Doubtful Accounts $546.
4. An invoice for $1,250 was due on March 1. The AR Aging report is run as of April 15. Into which aging bucket does this invoice fall, and why?
  1. Step 1 — Count days from the due date (March 1) to the report date (April 15): March has 31 days, so March 1 to March 31 = 30 days; add 15 days in April = 45 days past due.
  2. Step 2 — Match to the correct bucket: 45 days past due falls in the 31–60 days bucket (more than 30 but no more than 60 days past due).
Answer: The $1,250 invoice is 45 days past due and belongs in the 31–60 days aging bucket.
