Collateral Audits and Field Exams: How to Prepare and What They Test

When you borrow against accounts receivable, inventory, or other assets, your lender wants proof that the collateral backing your line actually exists and meets their criteria. That proof comes through collateral audits and field exams. These reviews can feel intrusive, but they serve a clear purpose: confirming that your borrowing base calculations are accurate and that the assets securing your credit line are real, collectible, and properly documented.

Preparation matters. A smooth audit protects your borrowing capacity and strengthens your relationship with your lender. A disorganized one can trigger reserve increases, line reductions, or heightened scrutiny. This article walks through what examiners test, how to prepare, and what happens after the review.

What Collateral Audits and Field Exams Actually Are

A collateral audit is a detailed review of the assets you've pledged as security. The examiner verifies that your borrowing base certificate matches reality. They test whether receivables are legitimate, whether inventory counts are accurate, and whether your internal controls prevent errors or fraud.

A field exam is the on-site version of this process. An examiner visits your location, inspects physical inventory, interviews staff, and reviews documents in real time. Field exams are more thorough than desk audits and typically happen annually or when a lender first underwrites a facility. Some lenders also conduct surprise exams if they see red flags in your reporting.

Both processes aim to answer the same question: does the collateral you report actually support the credit you're drawing? The depth and frequency depend on your loan structure, your industry, and your track record with the lender.

What Examiners Test in Accounts Receivable

Receivables are the most common form of asset-based collateral, and examiners scrutinize them closely. They start by selecting a sample of invoices from your borrowing base and tracing each one back to source documents—sales orders, shipping proof, customer contracts. They want to see that the receivable is real, that goods or services were delivered, and that the amount is correct.

Next, they test aging. If your borrowing base excludes invoices older than a certain number of days, the examiner checks whether you're applying that rule consistently. They also verify that you're not advancing against ineligible accounts, such as those tied to disputed invoices, foreign customers, or affiliates.

Concentration limits get tested too. If your facility caps how much you can borrow against any single customer, the examiner confirms you're staying within that threshold. They may also contact a few customers directly to confirm balances, especially if your records show large or aged amounts.

Finally, they review your collections process. Are you following up on past-due accounts? Are credits and adjustments documented? Weak collection practices signal higher risk, even if the invoices themselves are valid.

What Examiners Look for in Inventory

Inventory audits begin with a physical count. The examiner observes your team as they count stock, then selects random items to verify quantities and condition. They're checking whether your records match what's actually on hand and whether you're storing goods properly.

They also assess obsolescence. If you manufacture or distribute products with short shelf lives or rapid model changes, the examiner evaluates how much of your inventory is slow-moving or outdated. Lenders typically exclude obsolete stock from the borrowing base, so discrepancies here can reduce your availability.

Cost verification is another focus. The examiner reviews your inventory valuation method and tests whether the costs you report align with purchase invoices or production records. Overstated values inflate your borrowing base and create risk for the lender.

For raw materials and work-in-progress, examiners assess marketability. Can the inventory be sold as-is if the lender needs to liquidate? Highly specialized or custom goods may be excluded or heavily discounted in the borrowing base formula.

How to Prepare Before the Examiner Arrives

Preparation starts weeks before the audit date. Begin by running your own internal review. Pull a sample of receivables and trace them to source documents. Reconcile your inventory records to your general ledger. Identify any discrepancies and fix them before the examiner finds them.

Organize your documentation. Examiners will request aging reports, shipping logs, sales orders, purchase orders, and proof of delivery. Have digital and physical files ready and easy to access. If your records are scattered across multiple systems, create a clear map so you can pull information quickly.

Brief your team. The examiner will likely speak with your accounting staff, warehouse manager, and collections team. Make sure everyone understands the process and knows where to find key documents. Inconsistent answers or confusion can raise red flags.

Clean up your workspace. If the exam includes a site visit, ensure your warehouse is organized and that inventory is clearly labeled. Examiners notice operational discipline, and a well-run facility builds confidence.

Finally, review your borrowing base certificate for accuracy. Double-check that you've applied all eligibility rules correctly and that your calculations match your lender's formula. Errors here are the most common cause of audit adjustments.

What Happens During the Exam

On exam day, the process typically begins with an opening meeting. The examiner explains their scope, timeline, and what they'll need from your team. They'll ask for access to your accounting system, physical inventory locations, and key personnel.

The examiner then works through their testing plan. For receivables, they'll pull samples and request supporting documents. For inventory, they'll observe counts and inspect storage areas. They may also review your cash application process, lien documentation, and compliance with loan covenants.

Expect questions. Examiners ask about unusual transactions, large credits, customer disputes, and changes in your business. Answer directly and provide context when needed. If you don't know something, say so and offer to follow up.

The exam can take anywhere from a few hours to several days, depending on the size of your facility and the complexity of your collateral. Stay available and responsive. Delays frustrate examiners and can extend the process unnecessarily.

What Happens After the Audit

Once the fieldwork is complete, the examiner prepares a report for your lender. The report summarizes their findings, highlights any discrepancies, and recommends adjustments to your borrowing base or loan terms.

If the audit goes smoothly, you may see no changes. If the examiner identifies issues—such as ineligible receivables in your base or inventory valuation errors—your lender may impose reserves or reduce your line temporarily until you correct the problems.

Serious findings can trigger more frequent audits, tighter reporting requirements, or even a default notice if the issues are material. That's why accuracy and transparency matter. Small mistakes are fixable. Patterns of carelessness or misrepresentation erode trust quickly.

You'll typically receive a copy of the audit report. Review it carefully and address any action items promptly. If you disagree with a finding, discuss it with your lender and provide supporting evidence. Most lenders are willing to work through gray areas if you engage constructively.

Frequently Asked Questions

How often do lenders conduct collateral audits?

Most asset-based lenders perform field exams annually, though the frequency can increase if your borrowing base is volatile, if you're a new client, or if prior audits revealed issues. Some lenders also conduct desk reviews quarterly or semi-annually between full field exams.

Can I refuse a field exam?

No. Your loan agreement includes a clause granting the lender the right to audit your collateral. Refusing access is a default event and can result in immediate termination of your credit line. Cooperation is a condition of the facility.

What if the audit finds errors in my borrowing base?

The lender will adjust your availability to reflect the correct collateral value. If you've overdrawn as a result, you may need to pay down the line or provide additional collateral. Going forward, the lender may impose reserves or require more frequent reporting until you demonstrate consistent accuracy.

Do I have to pay for the audit?

Yes. Most asset-based loan agreements require the borrower to reimburse the lender for audit costs, typically subject to an annual cap. Costs vary based on the scope and duration of the exam, but budgeting for at least one full field exam per year is standard practice.
