Can You Sell Your Business If You Have Unpaid Invoices?
Yes, you can sell your business with unpaid invoices. Accounts receivable are a normal balance sheet asset in every business sale, not a liability. Invoices are either included in the deal at a discount based on aging or excluded so the seller collects them after closing. Working capital adjustments at closing ensure neither party overpays. Current invoices retain near full value, while invoices over 90 days may be discounted 40 to 50 percent.
Key Takeaways
- Accounts receivable are an asset, not a liability, and are a standard component of every business sale 2.
- Current invoices (0-30 days) retain 95-100% of face value, while 90+ day invoices may be discounted 40-50% 3.
- Over 90% of private M&A transactions include a working capital adjustment mechanism at closing 5.
- Buyers in middle-market deals typically include A/R in the purchase price with aging-based discounts 8.
- Bad debt reserves are tax-deductible under IRC Section 166 using the specific charge-off method 1.
How Do Unpaid Invoices Affect a Business Sale?
This condition doesn't make your business unsellable — but it does change the math. Here are the primary ways it impacts your transaction.
A/R Aging Determines Value
The age of your unpaid invoices directly affects their value to a buyer. Current invoices (0-30 days) are worth 95-100% of face value, while invoices past 120 days may be worth only 20-30 cents on the dollar 3. The aging schedule is the single most important factor.Working Capital Adjustment at Closing
Most deals use a working capital peg based on a trailing 12-month average. If your actual working capital at closing falls below the peg, the purchase price is reduced dollar-for-dollar. If it exceeds the peg, you receive more 5.Buyer May Purchase A/R Directly
In middle-market transactions, buyers often purchase accounts receivable at a discount as part of the deal. The discount reflects collection risk based on aging. Alternatively, the seller retains A/R and collects post-close — common in smaller deals 4.A/R Classified as Class III Assets
Under IRC Section 1060, accounts receivable are Class III assets in the residual allocation method. They are allocated at fair market value and any gain is taxed as ordinary income, not capital gains 1. This affects both buyer and seller tax positions.Asset Sale vs. Stock Sale: How Unpaid Invoices Are Handled
| Factor | Asset Sale | Stock Sale |
|---|---|---|
| A/R Transfer | Seller typically retains A/R and collects post-close, or buyer purchases at discount | A/R transfers automatically with the entity; no separate transfer needed |
| Tax Treatment of A/R | Class III asset under IRC Section 1060; gain taxed as ordinary income 1 | No separate A/R taxation; included in overall stock gain (capital gains rate) |
| Working Capital Adjustment | A/R included in net working capital peg; buyer and seller negotiate target 5 | Same working capital mechanism applies; A/R part of entity-level NWC |
| Bad Debt Risk | Seller bears risk on retained A/R; buyer bears risk on purchased A/R | Buyer assumes all collection risk as new entity owner |
| Customer Notification | Required if seller retains A/R; customers must know who to pay 6 | No customer notification needed; same entity continues billing |
| Frequency in SMB Deals | More common; over 70% of small business transactions use asset structure 4 | Less common; typically used in middle-market deals to preserve contracts |
| Best When... | A/R is clean and current, seller wants a simple exit, or buyer wants fresh start | A/R is deeply integrated with customer contracts, or novation would be complex |
What Happens to Each Type of Receivable When You Sell?
Not every situation is treated the same. Each type has different transfer rules, timelines, and risks that affect your sale.
Current Invoices (0-30 Days)
Transfer Rule
Included at near face value in working capital or purchased at 0-5% discount
Typical Handling
Counted toward working capital peg at approximately 95-100% of face value
Timeline
Collected within 30 days of invoice date
Watch Out
Even current invoices from financially distressed customers should be flagged and potentially reserved 3.Past Due (31-60 Days)
Transfer Rule
Included in working capital with 10-15% discount applied
Typical Handling
Buyer accepts at 85-90% of face value, or seller retains and collects post-close
Timeline
Collection efforts typically resolve within 2-4 weeks
Watch Out
A pattern of invoices consistently aging to 31-60 days signals weak collection processes to buyers 7.Significantly Past Due (61-90 Days)
Transfer Rule
Discounted 20-27% or excluded from working capital entirely
Typical Handling
Seller retains these invoices in most deals; buyer takes at steep discount if included
Timeline
Collection becomes uncertain; may require escalation or payment plans
Watch Out
Buyers view 61-90 day receivables as evidence of customer dissatisfaction or billing disputes 4.Severely Aged (91-120 Days)
Transfer Rule
Discounted 40-50% or excluded from the transaction entirely
Typical Handling
Almost always excluded from buyer's purchase; seller collects or writes off post-close
Timeline
Collection probability drops to 50-60%; consider third-party collection agencies
Watch Out
Under 26 CFR Section 1.166-1, bad debt deductions require specific charge-off, not general reserve 1.Write-Off Candidates (120+ Days)
Transfer Rule
Worth only 20-30% of face value; almost never included in the transaction
Typical Handling
Seller writes off pre-closing or sells to collection agency at 10-20 cents on the dollar
Timeline
6-12 months to resolve through collections or litigation
Watch Out
Large 120+ day balances signal to buyers that the seller has been deferring bad debt recognition 3.How to Sell Your Business With Unpaid Invoices: Step-by-Step
Prepare a Detailed Accounts Receivable Aging Report
Generate a complete A/R aging schedule showing every outstanding invoice by customer, amount, date issued, and days past due. Categorize into standard aging buckets: current, 31-60, 61-90, 91-120, and 120+ days. This report becomes a core due diligence document and directly affects the purchase price.
Pro tip: Run the aging report as of month-end for clean comparisons. Buyers will cross-reference against your accounting system 7.
Establish a Bad Debt Reserve Based on Historical Data
Calculate your historical collection rates by aging bucket over the past 24-36 months. Apply these rates to current outstanding invoices to establish a defensible bad debt reserve. Under 26 CFR Section 1.166-1, reserves must use the specific charge-off method for tax deductions.
Pro tip: A well-documented reserve using historical data is far more credible to buyers than an arbitrary percentage 1.
Negotiate the Working Capital Peg with the Buyer
The working capital peg is the agreed-upon normal level of net working capital. It is typically set using a trailing 12-month average, normalized for seasonality. Both parties should agree on the peg early in the LOI phase because deviations at closing directly adjust the purchase price.
Pro tip: Request a 24-month trailing average if your business is seasonal. This smooths out A/R fluctuations 5.
Decide Whether to Include or Exclude A/R from the Deal
In smaller deals, sellers often retain A/R and collect post-close, keeping the purchase price simpler. In middle-market deals, buyers typically purchase A/R at a discount. The decision depends on the aging profile, customer relationships, and whether the seller wants a clean break.
Pro tip: If more than 20% of A/R is over 60 days, consider excluding it and collecting yourself. Buyer discounts will be steep 3.
Structure the Post-Close True-Up Window
The purchase agreement should specify a 60-90 day true-up period after closing. During this window, the buyer prepares a final working capital statement, the seller reviews it within 30 days, and any disputes go to an independent accounting firm. Typically 1-5% of deal value is escrowed for adjustments.
Pro tip: Negotiate a materiality threshold for disputes. Small variances under $10K should not trigger the formal resolution process 8.
What Are the Biggest Risks of Selling a Business With Unpaid Invoices?
Stale Receivables Reduce Proceeds
Invoices aging past 90 days lose value rapidly. A $100K portfolio of 120+ day invoices may be worth only $20-30K to a buyer. If your A/R skews old, your working capital will fall below the peg, triggering a purchase price reduction at closing [3].
Customer Concentration in A/R
If a single customer represents more than 25% of your outstanding A/R, buyers view that as concentration risk compounding collection risk. A large receivable from one customer that becomes uncollectible could trigger a material working capital shortfall [4].
Post-Close Collection Disputes
When the seller retains A/R, customers may be confused about who to pay. Contacting customers post-close can also reveal the sale prematurely. The purchase agreement must clearly define collection rights, customer communication protocols, and payment forwarding [6].
Working Capital True-Up Surprises
Buyers prepare the final working capital statement and tend to be aggressive in their calculations. In 55% of deals, the post-close adjustment favors the buyer. Sellers who do not negotiate clear definitions of included items in advance often lose money in the true-up [5].
What Unpaid Invoice Red Flags Make Buyers Walk Away?
Knowing what buyers scrutinize helps you prepare. Address these before going to market.
More than 30% of A/R over 90 days past due
A high percentage of severely aged receivables suggests systemic collection problems or customer dissatisfaction. Buyers will discount heavily and may question whether revenue was booked prematurely.
Single customer represents over 40% of outstanding A/R
Extreme concentration in receivables means one customer default could wipe out a significant portion of working capital. Buyers will demand escrow or holdback provisions to cover the concentration risk [4].
No formal collections process or aging tracking
The absence of systematic collections indicates management neglect. Buyers see this as a sign that the reported A/R balance is unreliable and the true collectible amount may be substantially lower [7].
Increasing days sales outstanding trend over 12 months
Rising DSO signals deteriorating customer payment behavior or loosening credit terms. This trend erodes working capital and suggests the problem is worsening rather than stabilizing.
Disputed invoices exceeding 10% of total A/R
High dispute rates indicate potential service quality issues, billing errors, or contractual disagreements. Disputed invoices are effectively worthless until resolved, reducing the reliable A/R base.
Bad debt write-offs increasing year over year
An upward trend in write-offs signals deteriorating customer quality or economic weakness in the seller's market segment. Buyers will apply higher discount rates to the entire A/R portfolio as a result [3].
How Is a Business With Unpaid Invoices Valued?
Accounts receivable affect the equity bridge between enterprise value and what the seller takes home.

− Bad Debt Reserve

= Net A/R Value
Included in working capital calculation
Key insight: The $43,000 bad debt reserve represents the discount applied to aging receivables. Current invoices ($200K) retain near full value, while 90+ day invoices ($30K) are discounted to roughly $9K. If the working capital peg is $250K and actual closing working capital is $220K, the buyer receives a $30K purchase price reduction. This means aging your receivables before a sale directly protects your proceeds.

Unpaid invoices are not a problem to solve before selling. They are a normal asset every buyer expects. The real question is whether your aging profile tells a story of healthy customer relationships or deferred collection problems. Document your reserves and let the working capital adjustment handle the rest.

Key Lessons
- Buyer included A/R in the purchase at 92% of face value ($386K), rewarding the seller for a clean aging profile with 55% current receivables.
- Working capital peg was set at $300K based on trailing 12-month average; actual closing NWC of $285K triggered a $15K downward price adjustment.
- Seller collected $28K of excluded 90+ day receivables post-close through direct outreach, recovering 83% of the excluded balance.
- Aging report preparation two months before listing allowed the seller to resolve three billing disputes, moving $35K from 61-90 days back to current.
How Do Unpaid Invoices Affect Taxes When Selling?
Asset Sale — A/R Sold to Buyer
Accounts receivable are Class III assets under IRC Section 1060. The gain between the seller's tax basis in the receivables (typically face value minus bad debt reserve) and the amount received is taxed as ordinary income, not capital gains. Both parties must file Form 8594 allocating the purchase price across asset classes.
Example
Seller with $350K face value A/R and $43K bad debt reserve has a basis of $307K. If buyer pays $307K for the A/R, the seller recognizes zero gain on the receivables. The reserve was already deducted under Section 166 1.Key point: A/R gains are always ordinary income under IRC Section 1060, regardless of holding period or entity type 1.
Asset Sale — Seller Retains and Collects A/R Post-Close
The seller retains the receivables and collects them in the normal course of business. No purchase price allocation to A/R is needed. Revenue was already recognized when invoices were originally booked. Any amounts that become uncollectible are deducted as bad debts under IRC Section 166.
Example
Seller retains $84K of 60+ day receivables, collects $56K over 90 days, and writes off $28K. The $28K bad debt deduction offsets ordinary income in the year of write-off 1.Key point: The specific charge-off method under 26 CFR Section 1.166-1 requires proof of worthlessness for each individual debt 1.
Stock Sale — A/R Transfers With Entity
In a stock sale, A/R is not separately allocated because the entity and all its assets transfer intact. The seller's gain is calculated on the stock, taxed at long-term capital gains rates (20% federal plus 3.8% NIIT = 23.8%) if held over one year. The buyer inherits the entity's tax basis in receivables.
Example
On a $3.42M stock sale, the seller pays 23.8% federal tax on gain. If the seller's stock basis is $500K, the taxable gain is $2.92M, resulting in approximately $695K federal tax 6.Key point: Stock sales avoid the ordinary income treatment on A/R, saving sellers the rate differential between ordinary and capital gains 6.
