Notes receivable and accounts receivable are both money owed to a business and both sit on the balance sheet as assets, but they’re not the same instrument. Accounts receivable is an informal, short-term balance created when you sell to a customer on credit and send an invoice. Notes receivable is a formal debt documented by a signed promissory note that states a principal amount, an interest rate, and a due date. The difference shapes how long you wait to get paid, how much you earn on the balance, and how strong your legal position is if the customer doesn’t pay.
Accounts Receivable: The Invoice-Based Balance
Accounts receivable is money customers owe your business for goods or services already delivered on credit. It sits under current assets on the balance sheet because collection is expected relatively quickly, usually within 30 to 90 days.1Legal Information Institute. Accounts Receivable
The arrangement runs on payment terms printed on the invoice. “Net 30” gives the customer 30 calendar days from the invoice date to pay in full. “1/10 Net 30” offers a 1% discount for paying within 10 days. Longer windows like Net 45 or Net 60 show up in industries where large orders take time to process.2U.S. Small Business Administration. How Net 30 Accounts Help Conserve Business Cash Flow
No signed loan agreement is involved. The sales invoice itself is the primary documentation, which is why AR is described as an informal extension of credit. That informality is what makes it so common in wholesale, manufacturing, and B2B services, where companies ship first and bill later as routine practice.
Because the collection window is short, most AR balances carry no interest. If a customer pays late, the penalty is typically a flat service fee rather than a compounding rate.
Notes Receivable: The Promissory Note
Notes receivable is a step up in formality. Instead of an invoice, the obligation is documented with a promissory note: a written, signed promise by the borrower (the “maker”) to pay a specific amount of money to the lender (the “payee”) under defined terms.3Legal Information Institute. Promissory Note That note usually spells out the principal amount, a stated interest rate, and either a fixed maturity date or a provision making it payable on demand.4Legal Information Institute.

Interest is a defining feature. Because notes receivable typically involve longer repayment periods than a 30-day invoice, the lender needs compensation for the time value of money. A note might run 180 days, one year, or several years. If maturity exceeds one year, the note moves from current assets to noncurrent assets on the balance sheet.
Interest follows a straightforward formula: Principal × Annual Interest Rate × Time as a fraction of a year. A $10,000 note at 8% annual interest for 90 days earns $10,000 × 0.08 × (90 ÷ 365), or roughly $197. Under accrual accounting, that interest is recorded as interest revenue as it accrues, whether or not the cash has arrived.
Notes receivable show up in two common situations. First, a company might issue a note as part of a large, structured transaction, such as selling expensive equipment or lending money to a subsidiary. Second, and this is where it matters in day-to-day practice, notes often arise when an existing AR balance goes delinquent. When a customer repeatedly fails to pay, the creditor may require them to sign a promissory note. That conversion formalizes the debt, usually adds an interest obligation, and gives the creditor a stronger position if the matter ends up in court.
The Key Differences at a Glance
The differences matter most when you’re evaluating credit risk, chasing collections, or reading a balance sheet.
- Documentation. AR is backed by a sales invoice. NR is backed by a signed promissory note, which functions as a formal debt instrument.
- Interest. AR almost never carries interest. NR almost always does, at a rate stated in the note itself.
- Term length. AR is short-term, typically 30 to 60 days. NR can run months or years, and long-term notes are classified as noncurrent assets.
- Legal enforceability. Both are legally enforceable, but a promissory note gives the creditor a cleaner path to judgment than an invoice does.
- Negotiability. A qualifying promissory note can be endorsed and transferred to a third party under UCC Article 3. An invoice cannot.
- Origin. AR arises from routine credit sales. NR arises from structured lending, large transactions, or the conversion of delinquent AR balances.
Despite these differences, both appear on the balance sheet as assets and are initially recorded at face value. Both also carry the risk that the customer never pays, which is where valuation and legal enforceability come into play.
Why a Promissory Note Carries More Legal Weight
A promissory note that meets certain requirements under the Uniform Commercial Code qualifies as a “negotiable instrument.” Under UCC Section 3-104, the note must contain an unconditional promise to pay a fixed amount of money, be payable on demand or at a definite time, and be payable to bearer or to order.5Legal Information Institute. UCC 3-104 Negotiable Instrument
The practical consequence of negotiability is transferability. The holder of a negotiable note can endorse it and sell it to a third party, and that new holder generally steps into the same collection rights as the original payee. An invoice doesn’t work that way. You can’t hand someone an unpaid invoice and give them the same kind of clean legal claim a promissory note provides.
That distinction also affects litigation. When a maker defaults on a promissory note, the note itself supplies the essential proof: signature, amount, rate, and due date, all in one document. Collecting on an unpaid invoice usually requires establishing the underlying contract, delivery of the goods or services, and the amount owed piece by piece.
When a Note Is Dishonored
A note is “dishonored” when the maker fails to pay at maturity. When that happens, the holder typically reclassifies the note back into accounts receivable, including the accrued interest, because the formal terms of the note have been breached. The total, principal plus any earned interest, becomes a standard receivable that the company will attempt to collect through normal channels or legal action.
If collection looks doubtful, the full amount gets evaluated against the allowance for uncollectible accounts. A dishonored note from a customer already in financial trouble may need to be written down immediately. This is one reason credit departments monitor the financial health of note makers throughout the life of the note, not just at origination.
How Each Is Valued on the Books
Under U.S. Generally Accepted Accounting Principles, receivables aren’t reported at their full face value. They’re reported at net realizable value, which is the amount of cash the company realistically expects to collect. The gap between face value and net realizable value is covered by an allowance for uncollectible accounts, sometimes called the allowance for doubtful accounts.
Two estimation methods exist, and they aren’t equally acceptable under GAAP:
- Direct write-off method. You record a bad debt expense only when a specific account is confirmed as worthless. It’s simple but violates the matching principle, because the expense often lands in a different period than the revenue it relates to. GAAP doesn’t permit this method for material receivable balances.
- Allowance method. You estimate bad debt expense in the same period as the related sales revenue, matching expenses with revenue. The estimate can be based on a historical percentage of credit sales, or on an aging schedule that categorizes outstanding balances by how far past due they are and applies higher uncollectible rates to older balances.
The aging approach tends to produce more accurate results. A balance that’s 30 days old might carry a 2% estimated loss rate, while one that’s 90 days past due might sit at 10% or higher. The older the receivable, the less likely you are to collect it.
The Shift to Expected Credit Losses
A significant change in how companies estimate uncollectible receivables came with the Current Expected Credit Losses (CECL) standard under FASB Accounting Standards Codification Topic 326. CECL became effective for all entities, including smaller reporting companies, for fiscal years beginning after December 15, 2022.6FDIC. Current Expected Credit Losses (CECL) Under the older model, companies recognized credit losses only when a loss was probable. CECL requires companies to estimate expected losses over the entire life of the receivable from the moment it’s recorded. The practical effect is that allowances tend to be recognized earlier and may be larger, especially for longer-term notes receivable.
Choosing Between the Two in Practice
For most routine credit sales, accounts receivable is the right tool. It’s fast, cheap to administer, and matches the rhythm of ordinary business: ship the goods, send the invoice, collect within a month or two. Requiring a promissory note on every sale would slow transactions and put customers off.
Notes receivable earns its place when the amount is large, the repayment period is long, or the risk of nonpayment is elevated enough to justify a formal debt instrument with interest attached. It’s also the natural response when an accounts receivable balance has already gone bad and the creditor wants to lock the customer into a firm repayment schedule with a documented obligation that will hold up in court. In that sense, the two aren’t strictly alternatives; they often mark two stages in the same collection story, with the note coming into play precisely when the informal arrangement has failed.
