Accounts Receivable and Related Concepts

Allowance for Doubtful Accounts (AFDA) and Bad Debt Expense

Normal Balance of AFDA: The normal starting balance for Allowance for Doubtful Accounts (AFDA) is a credit, as it's a contra-asset account, reducing the gross accounts receivable to its net realizable value.
Debit Balance in AFDA: It is possible for AFDA to have a debit balance. This occurs if actual write-offs in a period exceed the previous estimate for bad debts. This indicates that the initial prediction of uncollectible accounts was an underestimate.
- Example: If an estimate for uncollectible accounts was $1,100$ , but write-offs and recoveries for the term result in a trial balance that is a debit.
Temporary Nature of Debit Balance: While an AFDA can temporarily have a debit balance, it is not its normal state. The account will be adjusted to a credit balance again before the start of the next year through the bad debt expense adjustment.
Bad Debt Expense vs. AFDA: Bad Debt Expense is the amount recognized specifically within a given accounting period, reflecting the cost of uncollectible accounts for that period. AFDA, however, represents an accumulated series of past estimations over time. It's built up from previous period's bad debt expenses and reduced by actual write-offs.
Calculating Bad Debt Expense: The bad debt expense for a period is the dollar difference between the AFDA's trial balance (before year-end adjustment) and its desired ending credit balance (typically determined by an aging schedule or percentage of sales).
- Misconception: It's incorrect to simply "write off" an uncollectible account directly to bad debt expense at the time of write-off. Bad debt expense is typically recognized at the end of the term as an adjustment to AFDA, to match estimated uncollectibles to the period's revenue.
- Sometimes customers unexpectedly pay, even if previously deemed uncollectible. The adjustment at term-end accounts for the difference between predictions and reality.

Write-offs and Recoveries

Journal Entry for Write-off: When an account receivable is deemed uncollectible and written off, the journal entry is:
- Debit: Allowance for Doubtful Accounts (reduces the contra-asset, reflecting the prediction coming true).
- Credit: Accounts Receivable (removes the specific customer's balance from AR).
Recovery of a Previously Written-Off Account (Two Journal Entries): If an account receivable that was previously written off is later collected, two journal entries must be made. This is a non-optional, critical process:
- Step 1: Reinstate the Receivable: This reverses the original write-off, correcting the initial (unintentional) mistake and restoring the customer's ledger to show they paid.
  - Journal Entry S1: Debit Accounts Receivable, Credit Allowance for Doubtful Accounts.
    - This entry can seem counter-intuitive as it increases the AFDA credit balance, but its purpose is to reverse the earlier debit to AFDA from the write-off, effectively nullifying the mistake.
- Step 2: Record Cash Collection: This records the actual inflow of cash for the payment.
  - Journal Entry S2: Debit Cash, Credit Accounts Receivable.
- Importance: This two-step process ensures accurate customer tracking (showing they eventually paid), correctly adjusts the AFDA, and provides a clear audit trail. Skipping Step 1 and directly debiting Cash and crediting AFDA would result in loss of specific customer payment information and an inaccurate adjustment to AFDA.
- Partial Payment: If only a part of the previously written-off amount is collected, the reinstatement (Step 1) should only be for the portion collected, followed by the cash collection (Step 2) for that same amount.

Notes Receivable

Similarities with Accounts Receivable (AR):
- Both appear on the balance sheet as assets.
- Both represent an expectation of future payment from a customer or borrower.
- Both can potentially be sold to a third party (e.g., factoring).
- Both are subject to the risk of non-payment (require flexibility for potential uncollectibles).
Differences from Accounts Receivable (AR):
- Formality: Notes Receivable are formal contracts (promissory notes), whereas AR is typically an informal agreement (often a
