Industry Insight: Handling Law Firm Accounting in Audit Sight (Proof of Cash & COA Mapping)

Law firms present unique accounting characteristics that can materially impact the Proof of Cash results if not properly mapped. Two of the most important areas are:

1. Trust Liability Accounts (Client Retainers)
2. Case Expenses / Billed Expenses

This article outlines how these accounts function economically and how they should be mapped within Audit Sight to ensure an accurate and meaningful Proof of Cash.

1. Trust Liability Accounts (Client Retainers)

What is a Trust Liability?

Law firms commonly require clients to prepay retainers, which are held in a trust account (often referred to as IOLTA accounts).

From an accounting perspective:

• The cash is received upfront
• The firm does not yet earn the revenue
• Therefore, the amount is recorded as a liability, not revenue

This is typically labeled as:

• Trust Liability
• Client Trust Account
• Retainer Liability

How It Works Operationally

1. Client deposits funds → recorded as:
   • Debit: Cash (Trust Account)
   • Credit: Trust Liability
2. As legal services are performed:
   • The firm earns revenue
   • Funds are transferred from the trust account to operating cash
3. Entry upon earning revenue:
   • Debit: Trust Liability
   • Credit: Revenue
   • Cash is simultaneously moved from trust → operating

Audit Insight

Although this sits on the balance sheet as a liability, economically:

• The reduction in trust liability represents earned revenue
• The movement of cash from trust to operating reflects realization

How to Map in Audit Sight

Audit Sight does not currently have a dedicated “Trust” category. Therefore:

👉 Map Trust Liability accounts as “Customer Deposits”

Why This Matters for Proof of Cash

When mapped as Customer Deposits:

• Changes in the account are treated as revenue-side activity
• Decreases in trust liability properly align with earned revenue
• The Proof of Cash reflects the true revenue lifecycle, not just cash movement

Expected Outcome

• Eliminates distortion where trust movements appear as unexplained reconciling items
• Aligns cash inflows and revenue recognition timing
• Produces a cleaner, more interpretable Proof of Cash

2. Case Expenses / Billed Expenses

What Are Case Expenses?

Law firms frequently incur costs on behalf of clients, such as:

• Filing fees
• Expert witness fees
• Travel costs
• Court-related expenses

These are:

• Paid upfront by the firm
• Billed back to the client for reimbursement

How They Are Often Recorded

In practice, firms may record these as:

• Prepaid expenses
• Other assets
• Work-in-progress (WIP)

However, economically:

• These amounts represent recoverable billings from clients
• They function much more like Accounts Receivable

How It Works Operationally

1. Firm incurs expense:
   • Debit: Case Expense Asset (or Prepaid)
   • Credit: Cash
2. Firm bills client:
   • Debit: Accounts Receivable
   • Credit: Expense Recovery / Revenue (or netted)
3. Client reimburses:
   • Debit: Cash
   • Credit: Accounts Receivable

Audit Insight

Even when classified as a prepaid or asset:

• These balances are directly tied to client billing and recovery
• They behave like extensions of revenue activity, not true operating expenses

How to Map in Audit Sight

👉 Map Case Expenses / Billed Expenses as “Accounts Receivable”

Why This Matters for Proof of Cash

When treated as AR:

• Changes are captured on the revenue side of the Proof of Cash
• Reimbursements align with client collections
• Avoids misclassification as operating or investing activity

Expected Outcome

• Prevents artificial reconciling items
• Aligns expense recovery with client-driven cash flows
• Improves revenue-to-cash traceability

Why This Mapping Improves Proof of Cash

Both of these adjustments achieve the same objective:

1. Align Economic Reality with Presentation

• Trust liabilities → represent deferred revenue becoming earned revenue
• Case expenses → represent recoverable client billings

2. Eliminate Noise in Reconciling Items

Improper mapping often results in:

• Large unexplained reconciling items
• Misclassified inflows/outflows
• Distorted revenue analytics

3. Standardize Law Firm Workflows

Applying consistent mappings across engagements:

• Improves comparability
• Reduces manual adjustments
• Accelerates review and analysis
