Notes Receivable, Explained: How Written Promises to Pay Differ From Open Accounts

A customer's invoice is 60 days overdue, and instead of paying, they offer you a signed promise: "Give me 90 more days and I'll pay the full balance plus 8% interest." That signature changes everything about how the amount lives on your books. It is no longer an open account you hope to collect — it is a note receivable, a negotiable instrument with its own interest math, its own journal entries, and its own ways to go wrong at month-end.

This guide walks through how notes receivable work: the parties and terms on a promissory note, how they differ from ordinary accounts receivable, the entries for recording, accruing, and collecting a note, what happens when the maker doesn't pay, and how discounting a note at the bank turns future cash into cash today.

Notes Receivable vs. Accounts Receivable​

Both are assets. Both represent money customers owe you. The difference is formality — and formality changes the accounting.

An account receivable says "you bought it, pay us." A note receivable says "you promise in writing to pay this exact amount, plus interest, on this exact date" — and that written promise is enforceable paper you can take to a bank. Businesses usually end up holding notes in three situations: a customer converts an overdue open balance into a note to get more time, a large sale closes on extended payment terms documented as a note, or the company lends money to an employee or officer and documents it properly.

Because a note can stretch past a year, classification matters. A note due within one year of the balance sheet date sits in current assets; a note with a longer term is a non-current asset. Get this wrong and your current ratio — the number lenders actually look at — is misstated.

The Anatomy of a Promissory Note​

Every promissory note names the same cast of characters and numbers. Learn these five terms and you can read any note:

• Maker — the borrower. The party who signs the note and promises to pay. On the maker's books, the same instrument is a note payable.
• Payee — the lender. The party who receives payment — that is you, when you hold a note receivable.
• Principal — the face amount borrowed, the base on which interest is computed.
• Rate and term — the stated annual interest rate and the note's life, expressed in days, months, or years.
• Maturity date and maturity value — the day payment is due and the total the maker must pay: principal plus all interest.

Interest on short-term notes is almost always simple interest:

Interest = Principal × Rate × Time

Time is expressed as a fraction of a year. A 90-day note uses 90/360 or 90/365 depending on the stated day-count convention (banker's-year 360-day math is still common on commercial paper — check the note), while a 3-month note uses 3/12. Take a $15,000 note at 8% for 3 months:

$15,000 × 8% × 3/12 = $300 of interest

The maturity value is $15,300 — the check the maker owes you on day 90. Nothing about this is revenue yet; the principal was already earned as a sale (or lent as cash), and the interest becomes revenue gradually as time passes. That timing point is where most bookkeeping mistakes start.

Recording a Note: The Three Journal Entries​

Follow one note from signing to collection and you have seen nearly the whole lifecycle. Suppose a customer with a $15,000 overdue balance signs a 90-day, 8% note on October 1 to replace the open account.

1. Receiving the note​

No new revenue here — you are swapping one asset for a stronger one:

• Debit Notes Receivable $15,000
• Credit Accounts Receivable $15,000

If instead you lent cash, you would credit Cash rather than Accounts Receivable. Either way, the principal lands in Notes Receivable at face value.

2. Accruing interest at period-end​

This is the entry people forget. Interest accrues with time, not with cash changing hands, so at every month-end (and always at year-end) you book the interest earned so far. One month of our example note earns $100 ($15,000 × 8% × 1/12):

• Debit Interest Receivable $100
• Credit Interest Income $100

When a note spans a fiscal year-end — signed in November, maturing in February — this adjusting entry is what puts each year's interest in the right year. Skip it and you understate both assets and income in the old year, then overstate income when the full amount arrives in the new year. Auditors test this cutoff routinely.

In a plain-text ledger the same lifecycle reads naturally. Here is the receipt and one month of accrual in Beancount, with interest tracked as it is earned rather than when cash arrives:

2026-10-01 * "Customer converts overdue balance to 90-day 8% note"
  Assets:Notes-Receivable:Customer-A   15000.00 USD
  Assets:Accounts-Receivable:Customer-A  -15000.00 USD
 
2026-10-31 * "Accrue October interest on Customer-A note"
  Assets:Interest-Receivable:Customer-A   100.00 USD
  Income:Interest:Notes-Receivable  -100.00 USD

3. Collecting at maturity​

On December 30 the maker pays the full $15,300. You already accrued two months of interest ($200 sitting in Interest Receivable), so only December's $100 is new income:

• Debit Cash $15,300
• Credit Notes Receivable $15,000
• Credit Interest Receivable $200
• Credit Interest Income $100

The pattern to internalize: principal was never income, accrued interest was income in earlier periods, and only the final stub period's interest hits income at collection. If your software books the whole $300 as income on collection day, your monthly profit figures are wrong in three months, not just one.

When the Maker Doesn't Pay: Dishonored Notes​

A note the maker fails to pay at maturity is dishonored. Dishonor doesn't erase the debt — it demotes the instrument. You no longer hold a note; you hold a delinquent claim, possibly with extra costs attached.

Suppose our $15,300 note comes due and the check bounces. The entry transfers everything you are owed back to accounts receivable:

• Debit Accounts Receivable $15,300
• Credit Notes Receivable $15,000
• Credit Interest Receivable $200
• Credit Interest Income $100

If you paid a bank protest fee or legal costs to pursue collection, those get debited to Accounts Receivable too — they are part of what the customer now owes you. From there, normal collections practice applies: pursue, renegotiate, or eventually write off through the allowance for doubtful accounts.

Two practical notes. First, keep accruing interest after dishonor only if collection remains reasonably assured; booking interest income on a debt you will never collect inflates income today and forces a bigger write-off later. Second, act fast — a dishonored note is often the first hard evidence that a customer's troubles are serious, and the longer you wait, the further back in the creditor line you stand.

Discounting: Turning a Note Into Cash Before Maturity​

Because a note is negotiable paper, you don't have to wait for maturity. You can discount it at a bank: the bank gives you cash now, collects from the maker later, and keeps a fee for the service. Companies do this when cash is tight and a good note is sitting idle.

The bank's fee is the discount, computed on the maturity value over the period the bank will hold the note (the discount period):

Bank discount = Maturity value × Discount rate × Discount period

Proceeds = Maturity value − Bank discount

Say you discount that $15,300 note 30 days before maturity and the bank charges a 10% discount rate. The discount is $15,300 × 10% × 30/360 = $127.50, so you walk out with $15,172.50. The $127.50 difference is interest expense — the cost of getting your money early.

The fine print that matters is recourse:

• Discounted with recourse (the common case for small businesses): if the maker dishonors the note, the bank comes back to you for the full maturity value plus fees. You carry a contingent liability until the note is paid, and you must disclose it. If dishonor happens, you debit Accounts Receivable for what you pay the bank and pursue the customer yourself.
• Discounted without recourse: the bank assumes the collection risk and your involvement ends. Banks charge more for this, or refuse it for makers they don't trust.

Before discounting, compare the discount rate against your other short-term options. A 10% bank discount rate for early cash can easily beat a merchant cash advance — or lose to a line of credit you already have. Run both numbers; desperation pricing is how businesses discount a good note at a bad rate.

Five Mistakes That Misstate Your Books​

1. Forgetting the period-end accrual. The single most common error. Any note outstanding at month-end or year-end needs its earned-to-date interest booked, or assets and income are understated.
2. Booking the maturity value as revenue at signing. The principal is a receivable swap or a loan, never new sales. Only interest, over time, is income.
3. Reading the note from the wrong side. Maker = debtor = note payable; payee = creditor = note receivable. The same piece of paper is a liability on one balance sheet and an asset on the other. Confirm which side you are on before posting.
4. Misclassifying by term. A note due in 18 months is non-current. Parking it in current assets overstates working capital — exactly the figure a lender checks before extending credit.
5. Forgetting a discounted note. With recourse, you still own the risk until maturity. Track discounted notes off to the side (a simple register of maker, maturity date, and amount suffices) so a dishonor notice never arrives as a surprise debit.

What to Do This Week​

If you already hold customer notes — or overdue balances that should become notes — three steps put you on solid ground. First, inventory every note: maker, principal, rate, dates, and whether each is current or non-current, and confirm the balance sheet classification matches. Second, verify that interest through the last month-end is accrued; if your books show a note with zero interest receivable beside it, the accrual entry is missing. Third, calendar every maturity date with a reminder a week ahead, so renewals, collections, and discount decisions happen deliberately instead of by accident.

Handled this way, a promissory note is one of the healthier things on a balance sheet: a customer's vague obligation converted into dated, interest-bearing, enforceable paper. The accounting is only a handful of entries — the discipline is in making every one of them on time.
