Commission Accounting: Revenue Recognition Under ASC 606

Before ASC 606, most companies treated sales commissions the way they paid them: cash out the door, expense recognized. A rep earned $8,000 on a deal that closed in Q1; Q1's income statement took the hit.

That changed when the Financial Accounting Standards Board issued ASC 606 (Revenue from Contracts with Customers) and its companion standard, ASC 340-40 (Other Assets and Deferred Costs — Contracts with Customers). For many companies, the commission accounting treatment that seemed obvious — expense it when you pay it — is no longer compliant with US GAAP.

Here's how it works, what it requires, and where the accounting intersects with your commission operations.

What changed under ASC 606

The underlying logic of ASC 606 is that revenue should be recognized as performance obligations are satisfied. The companion rule in ASC 340-40 extends that logic to the costs of obtaining contracts: if you capitalize the revenue, you should also capitalize the cost of acquiring it.

Under ASC 340-40-25-1, companies must recognize an asset for incremental costs of obtaining a customer contract if they expect to recover those costs. The asset is then amortized over the period that the costs are expected to benefit.

For most sales organizations, the primary incremental cost is the direct sales commission paid when a deal closes.

What counts as an incremental cost

The definition is precise. An incremental cost of obtaining a contract is a cost the entity would not have incurred if the contract had not been obtained.

Direct sales commissions paid on deal close qualify. If a rep receives $0 commission when a deal doesn't close, and $9,000 when it does, that $9,000 is incremental.

The following typically do not qualify:

• Base salary (the rep would be paid regardless of whether any specific deal closed)
• Pre-sale travel or demo costs (incurred whether or not the deal closed)
• Legal fees for contract negotiation (incurred during the process, not conditional on outcome)
• Sales manager salaries and overhead

Companies should work with their auditors to define which cost components are incremental. The FASB's codification is clear on the principle; application to specific compensation structures requires judgment.

The amortization period

Once you've identified which costs to capitalize, you need to determine the amortization period. This is where most companies get it wrong.

The amortization period is not simply the initial contract term. Under ASC 340-40, the period should reflect the expected customer relationship — including anticipated renewals — if those renewals are expected and the commission was meant to benefit the full relationship, not just the initial contract.

In practice:

• For a one-year SaaS contract with a high renewal rate and no additional commissions paid at renewal, the amortization period may extend well beyond one year — potentially 3 to 9 years for typical enterprise SaaS customers
• If renewal commissions are paid and are commensurate with initial contract commissions (meaning the commission rate is similar and not just a small "renewal kicker"), companies may be able to amortize initial contract commissions over the initial contract term rather than the full expected customer life
• "Commensurate" is a judgment call that requires documentation and auditor agreement

The KPMG and Deloitte guidance on ASC 606 for software companies indicates SaaS amortization periods in the range of 3 to 9 years depending on expected customer life and renewal commission structure. A company selling annual contracts with high renewal rates and no renewal commissions is more likely to use the longer end of that range.

The practical expedient

There is one way to keep expensing commissions immediately: the practical expedient in ASC 340-40-25-4.

If the amortization period of the capitalized asset would be one year or less, the company may elect to expense incremental contract costs when incurred rather than capitalizing them.

This election:

• Is a policy choice, not a contract-by-contract decision
• Must be applied consistently to all contracts with similar characteristics
• Must be documented and disclosed in financial statements

Who can use it: Companies selling short-term contracts (under 12 months) with limited renewals. Transactional businesses. Companies where expected customer lifetime is less than a year.

Who typically cannot: SaaS companies with multi-year expected customer relationships, even if they sell month-to-month or annual contracts. If your average customer relationship lasts 3 years and you expect renewal commissions to differ from initial commissions, the amortization period likely exceeds one year.

What the journal entries look like

At deal close (commission paid to rep):

DR  Deferred Commission Expense (Asset)     $9,000
    CR  Cash / Accrued Commissions Payable         $9,000

Each month over the amortization period (e.g., 36 months):

DR  Sales Commission Expense     $250
    CR  Deferred Commission Expense     $250

At period end, the unamortized balance sits on the balance sheet as a current or non-current asset depending on whether amortization is expected within 12 months.

For a $9,000 commission on a three-year contract, you'd recognize $250/month over 36 months instead of taking the full $9,000 hit in the period the deal closed.

What data you need to do this right

Commission accounting under ASC 606 requires deal-level data that many commission tracking systems don't capture. Specifically, you need:

For each deal:

• Commission amount paid and payment date
• Contract start date and initial contract term
• Expected customer relationship length (if different from initial term)
• Renewal commission rate (to determine if commensurate standard is met)
• Whether the deal was renewed, churned, or modified

For each period:

• Unamortized balance by deal
• Amortization schedule for all open contracts
• Impairment assessment if a customer churns mid-contract

The amortization schedule ties directly to the commission payout data. If a deal closes and the rep earns $12,000, finance needs the same deal data your commission spreadsheet or software is using. If those systems aren't connected, someone is manually reconciling payout records to accounting entries every period.

Impairment: what happens when a customer churns

If a customer cancels before the capitalized commission is fully amortized, the unamortized balance must be written off immediately as an impairment.

For a $9,000 commission on a 36-month contract, if the customer cancels at month 18 with $4,500 remaining on the asset, that $4,500 hits the income statement in the period of cancellation.

This creates an accounting interaction with clawback policies. If you have a clawback that recovers commission from the rep when a customer cancels, the net accounting effect is:

1. Clawback received from rep reduces the expense
2. Impairment write-off of unamortized balance increases it

These can offset partially or fully depending on clawback timing and percentage. Finance needs visibility into both the rep payout data and the churn event to get the entries right.

Where commission software fits in

Spreadsheet-based commission systems usually track what reps earned — not what was capitalized, how much has been amortized, or what's at risk from churned deals.

The finance team ends up maintaining a separate amortization schedule in Excel, manually pulling commission amounts from the comp spreadsheet each period. Any adjustment — a deal retraction, a clawback, a rep departure — requires an update in both systems.

Carvd tracks commission payouts at the deal level with the close date, contract term, and rep assignment that finance needs to build and maintain amortization schedules. The payout data and the accounting data can come from the same source.
