Asset-Based Loans: Build the Borrowing Base Before You Borrow

Asset-based lending is a reporting system

Asset-based loans are commonly revolving facilities whose availability rises and falls with eligible collateral. Accounts receivable and inventory often drive the borrowing base. Equipment or other assets may support a separate component, but the agreement determines what counts.

The FDIC's Commercial and Industrial Loans examination module describes asset-based loans as line-of-credit advances based on a borrowing base that can include a percentage of eligible receivables and inventory plus discounted machinery and equipment value. It distinguishes this structure from a conventional working-capital revolver because collateral is monitored in line with advances.

That distinction changes the borrower's job. Approval is only the start. The finance team must produce accurate borrowing-base certificates, customer agings, inventory reports, and reconciliations on schedule. Cash may flow through a lockbox or controlled account. The lender may conduct field audits and appraisals. A late report or unexplained variance can reduce confidence even when sales are growing.

An asset-based line can fit a company with a recurring conversion cycle: cash buys inventory or funds work, completed sales become receivables, customers pay, and the collections reduce the line. It can be a poor fit when records are weak, margins are collapsing, receivables are frequently disputed, inventory is obsolete, or collateral is difficult to identify and liquidate.

This guide focuses on the operating system behind the line. For a broader explanation of security interests, see Business Loan Collateral: What Lenders Take. For general cash-flow products, read Working Capital Loans.

Build the borrowing base from contract definitions

The borrowing base is not the total value on the balance sheet. It is a contractual calculation. Start with the stated collateral pool, remove ineligible items, apply the agreement's advance rates and limits, then subtract reserves and the current loan balance to determine remaining availability.

A receivable may be excluded because it is past the permitted age, disputed, owed by an affiliate, billed before delivery, concentrated in one customer above a cap, subject to offset, foreign without required support, or otherwise outside the eligibility definition. Inventory may be excluded because it is obsolete, work in process, consigned, stored where the lender lacks required control, slow moving, customized for one buyer, or difficult to sell.

Illustrative example, not an observed facility: eligible receivables of $900,000 multiplied by an 80% contractual advance rate produce $720,000, while eligible inventory of $400,000 multiplied by a 50% contractual advance rate produces $200,000. Source: Commera calculation using hypothetical inputs. After a $70,000 reserve, the illustrative borrowing base is $850,000. If $610,000 is outstanding, illustrative availability is $240,000 before fees, blocks, or other deductions.

The numbers are less important than the controls. Store each exclusion reason at the invoice or inventory-item level. Do not overwrite source reports to force them into the certificate. Keep a bridge from the general ledger to the aging, from the aging to eligible collateral, and from eligible collateral to the signed certificate.

The Federal Reserve's February 2026 examination manual defines a borrowing base as the amount a lender is willing to advance against pledged collateral value and says a borrowing-base certificate should be prepared at least monthly, or more often during peak activity. Your agreement can require a different cadence, including weekly or daily reporting.

Receivables require more than an aging report

A clean aging starts with a clean sales process. The lender may test invoices back to contracts, purchase orders, delivery records, customer acceptance, credits, and cash receipts. It may also confirm balances with customers.

Build these checks into ordinary close procedures:

1. Reconcile the accounts receivable control account to the customer aging.
2. Apply cash promptly and identify unapplied receipts.
3. Link every credit memo to the original invoice and reason.
4. Separate earned invoices from deposits, unbilled work, retainage, and contingent amounts.
5. Flag cross-aging, where a customer's old unpaid invoice can make its newer invoices ineligible.
6. Calculate customer concentration using the agreement's method.
7. Record disputes and offsets even when sales believes collection is likely.

The OCC's Accounts Receivable and Inventory Financing handbook describes specialized ABL as financing in which lenders closely control credit availability and collateral by setting a borrowing base, controlling cash receipts, and conducting field audits. It also warns that untimely receivable and inventory aging information can be a sign of increased credit risk.

Customer quality matters because the receivable is only as useful as the obligation behind it. A large invoice to a slow or disputing customer may create less availability than many smaller, current invoices. If government receivables are part of the pool, contract assignment, setoff, and payment mechanics can differ. See Government Receivables Financing and Working Capital for that context.

Inventory needs location, quantity, cost, and saleability

Inventory reporting should answer four questions: what exists, where it is, what it cost, and whether it can be sold. A perpetual inventory total without reliable counts or location records does not answer them.

Create an inventory file that distinguishes raw materials, work in process, finished goods, consigned goods, customer-owned goods, returns, damaged items, and obsolete or slow-moving stock. Reconcile the subledger to the general ledger and explain purchase-price, freight, overhead, and standard-cost variances. Identify third-party warehouses and processors. The lender may require landlord, warehouse, or bailee agreements before it gives value to inventory at those sites.

Advance value is not retail price. A lender considers the amount and time required to convert collateral into cash under stress, as well as removal, storage, completion, and sale costs. Appraisals may use orderly-liquidation or other defined value standards. Read the definition in the agreement and appraisal engagement rather than assuming that book value controls.

Cycle counts help detect problems before a field exam does. Investigate negative quantities, long-unmoved stock, duplicate item numbers, goods held at unreported locations, and large manual adjustments. Tie purchase receipts and production records to quantities. If availability depends on inventory, the finance and operations teams must own the data together.

Equipment can support some facilities, but it behaves differently from a revolving pool of invoices and inventory. Serial numbers, title, condition, location, useful life, and appraisal value matter. For purchase-specific structures, compare the process described in Equipment Financing Without Draining Cash.

Field exams, cash control, and covenant pressure

A field exam tests whether the reports and controls behind the borrowing base are reliable. Examiners can trace invoices to delivery, sample customer payments, test credits, inspect inventory, review eligibility, and reconcile collateral reports to the ledger. Treat the exam request list as a design specification for your reporting process.

Cash control connects collections to the loan. Customer payments may go to a lockbox, blocked account, or lender-controlled account and then reduce the outstanding balance. The lender may release funds back to the operating account subject to availability. Understand cut-off times, weekend processing, permitted disbursements, and how misdirected payments are handled.

An overadvance occurs when outstanding obligations exceed permitted availability. It can result from borrowing, customer payment patterns, new ineligibles, a reserve, a reduced advance rate, an appraisal change, or a reporting correction. The agreement may require prompt repayment and may give the lender other remedies. Build an early-warning forecast that shows projected availability after major invoices age out or seasonal inventory changes.

UCC Section 9-204 permits a security agreement to cover after-acquired collateral, subject to its exceptions. That supports a revolving structure in which new receivables and inventory enter the collateral pool. Perfection and priority require separate analysis. UCC Section 9-310 states the general model rule that a financing statement must be filed to perfect security interests, subject to listed exceptions. Search existing filings before negotiation; What Is a UCC Lien? explains how.

Never solve a certificate shortfall by delaying a credit memo or moving an old invoice to a new date. Correct the report, notify the lender as required, and agree on a cure. Reporting credibility is itself part of the credit relationship.

Compare facilities by usable liquidity

A large commitment can produce little usable cash if concentration limits, reserves, exclusions, and reporting blocks remove most collateral. Compare proposals using a recent clean data set and the exact eligibility definitions from each term sheet.

Model these items:

• commitment and sublimits by collateral type;
• advance rates and concentration limits;
• customer and inventory eligibility rules;
• minimum excess availability or covenant triggers;
• interest, unused-line charges, audit and appraisal costs, legal expenses, and termination fees;
• reporting frequency and required systems access;
• cash-control timing and permitted accounts;
• personal guaranties, cross-collateralization, and lien priority;
• discretionary overadvances and lender rights to add reserves;
• renewal, exit, and payoff procedures.

SBA's 7(a) Working Capital Pilot is one program to ask participating lenders about. SBA says the monitored line can support borrowing against accounts receivable and inventory, and its public 7(a) page says applicants should be able to produce timely financial statements, receivable and payable agings, and inventory reports. Eligibility and approval remain with the participating lender and SBA rules.

Run a reporting rehearsal before signing. Produce two consecutive certificates, attach every supporting report, complete the cash reconciliation, and simulate one large customer becoming ineligible. If the team cannot do that on time, fix the process or choose a simpler product.
