How Asset-Based Lending Works: ABL for Referral Partners

Asset-based lending is the working capital financing solution for mid-market businesses — manufacturers, distributors, staffing companies, and retailers that need flexible revolving credit tied to the assets driving their business. For referral partners, ABL represents a significant opportunity: it is the right product for businesses that have outgrown factoring or cannot get adequate bank lines, and a single well-placed ABL referral generates meaningful fees and long-term client value. This guide explains how ABL works, how the borrowing base is calculated, what field exams are, and when to route a client to ABL versus factoring or a conventional working capital loan.

  • Revolving credit line based on borrowing base — 80–85% on receivables, 50–65% on inventory
  • Business retains collections; customers are not notified of the facility
  • Typical facility sizes $1M–$50M+; serves manufacturing, distribution, retail, staffing

What Asset-Based Lending Is

Asset-based lending is a form of commercial credit in which the borrowing capacity of the facility is directly tied to — and limited by — the value of specific eligible business assets. Those assets form the collateral base for the facility, and the maximum amount the business can borrow at any moment is determined by a formula applied to those assets: the borrowing base.

The primary assets used in ABL are accounts receivable and inventory. Equipment is sometimes included, typically at lower advance rates, particularly for manufacturing businesses with significant machinery and equipment. Real estate is generally not part of an ABL borrowing base — real property is handled separately under commercial mortgage or owner-occupied real estate financing.

ABL is structured as a revolving credit facility, not a term loan. The business draws on the line when it needs capital — to fund payroll, purchase inventory, pay suppliers — and repays as customers pay invoices. The available credit expands when the business generates new receivables and contracts when customers pay (reducing the receivables base) or when inventory is sold (reducing inventory value). The borrowing base is recalculated regularly — often weekly or monthly — and the facility availability adjusts accordingly.

A key operational distinction between ABL and factoring: in ABL, the business continues to collect from its customers exactly as normal. Customers are not notified of the facility, do not pay the lender directly, and have no awareness that the business has pledged its receivables as collateral. The business deposits customer payments into a controlled account (a blocked account or lockbox), and the lender applies those deposits to reduce the outstanding balance. This "quiet" operation is significant for businesses that value maintaining direct customer relationships.

ABL lenders typically require a first-priority security interest in all of the business's assets — a blanket UCC-1 lien — in addition to the specific pledge of receivables and inventory. This means that if a business has an existing bank relationship with a blanket lien, the bank must release that lien (or subordinate its interest) before an ABL facility can be established. This is one of the first issues to identify in evaluating an ABL opportunity.

How the Borrowing Base Works

The borrowing base is the mathematical calculation that determines how much the business can borrow at any given time. It is calculated by applying advance rates to the value of eligible assets, then adding those components together.

The borrowing base calculation works in two steps: first, determine which assets are "eligible" (meet the lender's criteria for inclusion); second, apply the advance rate to the eligible assets to determine the available credit.

Example borrowing base calculation:

Asset category Total balance Ineligible/excluded Eligible balance Advance rate Availability
Accounts receivable $3,000,000 $400,000 (aged 90+ days, concentrated) $2,600,000 85% $2,210,000
Finished goods inventory $1,500,000 $300,000 (slow-moving, obsolete) $1,200,000 50% $600,000
Raw materials inventory $500,000 $100,000 (work-in-process) $400,000 40% $160,000
Total borrowing base availability $2,970,000

In this example, the business has $5 million in total assets on the balance sheet, but the borrowing base yields approximately $3 million in available credit. If the facility has a $4 million maximum commitment, the business can only borrow $3 million — the lesser of the commitment and the borrowing base.

The borrowing base fluctuates as the business operates. At the end of a strong shipping month, receivables increase and availability goes up. When a large customer pays a significant invoice, receivables decline and availability decreases. The ABL facility is self-liquidating in this sense — as the assets that supported borrowing are converted to cash, the outstanding balance naturally decreases.

Borrowing base certificates — formal calculations submitted to the lender — are typically required weekly or monthly. The frequency depends on the facility size and the lender's monitoring requirements. This reporting obligation is one of the operational costs of ABL that referral partners should communicate to clients evaluating ABL versus simpler products.

Advance Rates: Receivables, Inventory, and Equipment

Advance rates reflect the lender's assessment of how quickly and reliably a specific asset category can be converted to cash — particularly in a stressed or liquidation scenario.

Asset type Typical advance rate Eligibility notes
Accounts receivable (current, undisputed, B2B) 80–85% Eligible: under 90 days, undisputed, commercial customers. Ineligible: over 90 days, concentrated, government (some), related-party, consignment.
Finished goods inventory 50–65% Eligible: standard commercial inventory, readily marketable. Ineligible: slow-moving (over 180 days), obsolete, hazardous, consigned.
Raw materials inventory 40–50% Eligible: standard raw materials with ready market. Ineligible: highly customized materials with no secondary market, perishables.
Work-in-process (WIP) inventory 0–25% (often excluded) Most lenders exclude WIP or advance at very low rates — partially completed goods have limited liquidation value.
Equipment (when included) 50–75% of orderly liquidation value Based on appraisal; term loan component, not revolving. Most relevant for manufacturing.

The receivables advance rate is the highest because receivables convert to cash on a defined schedule without the need for a sale — the customer simply pays the invoice. Inventory requires a subsequent sale to convert to cash, and in a distressed scenario, that sale may happen at a discount, which is why advance rates are lower. WIP is difficult to sell in any scenario, which is why it is often excluded entirely.

Field Exams and Ongoing Reporting

Asset-based lending involves a level of ongoing monitoring that does not exist in factoring or term lending. This monitoring is necessary because the lender's security is in assets that change in value every day — receivables are generated and collected, inventory is purchased and sold, and the quality of these assets can change quickly.

Field examinations (also called collateral audits or field exams) are the primary monitoring tool. A field exam involves the lender's auditors — either in-house examiners or a third-party field exam firm — visiting the borrower's location to:

  • Verify that the accounts receivable aging accurately reflects real, outstanding invoices
  • Review a sample of invoices for authenticity, proper documentation, and customer acknowledgment
  • Physically inspect inventory to confirm it exists as reported and assess its condition and marketability
  • Review the borrower's accounts receivable ledger and cash receipts to verify proper lockbox or blocked account operation
  • Evaluate the internal controls the business uses to manage its receivables and inventory

Field exams are conducted at origination (before the facility is established) and then annually for well-performing facilities, or more frequently — semiannually or quarterly — for facilities showing signs of stress, concentration issues, or reporting irregularities. Field exam costs are borne by the borrower and typically range from $1,500 to $5,000 per exam, depending on the size and complexity of the business.

Ongoing reporting requirements for an ABL facility typically include:

  • Weekly or monthly borrowing base certificates showing eligible receivables, eligible inventory, and calculated availability
  • Monthly accounts receivable aging reports
  • Monthly or quarterly inventory reports (cost reports by category)
  • Monthly financial statements (income statement, balance sheet)
  • Annual audited or reviewed financial statements

The reporting obligation is real and requires internal finance capacity. For businesses without an accounting staff capable of producing accurate, timely borrowing base certificates, ABL may not be the right fit — at least not until the business builds that capacity. This is an important screening question for referral partners evaluating whether ABL or factoring is more appropriate.

ABL vs. Factoring vs. Conventional Credit Line

Feature ABL Invoice factoring Conventional credit line
Structure Revolving credit, borrowing base Sale of invoices Revolving credit, cash flow based
Primary collateral Receivables + inventory Receivables (sold to factor) Business assets, personal guarantee
Customer awareness None — business collects normally Customers notified (usually) None
Qualification driver Asset quality and value Customer creditworthiness Business credit, profitability, cash flow
Typical cost Prime + 2–5% on drawn balance 1–5% per 30 days Prime + 1–3% (lowest cost)
Minimum deal size $1M+ annual receivables No strict minimum Varies — bank determines
Reporting burden High — weekly/monthly borrowing base certs, field exams Medium — invoice-level documentation Low — annual reviews typically

The key insight for routing decisions: a conventional credit line is the least expensive and least burdensome, but the hardest to qualify for — banks require strong financials, profitability, and credit. ABL is the next tier — it substitutes asset quality for credit quality, making it accessible to businesses that cannot get bank lines but have good assets. Factoring is the most accessible entry point, requires the least infrastructure, and outsources collections, but is the most expensive per dollar of financing and involves customer notification.

Typical ABL Deal Sizes and Structure

ABL facilities vary widely in size, from the lower end of the mid-market (facilities of $1–$5 million) through large corporate ABL revolvers that can exceed $500 million for major manufacturers or retailers. For referral partners working with small to mid-size businesses, the relevant range is typically $1 million to $50 million.

Lower end ($1M–$5M): Facilities in this range serve businesses with $2–$15 million in annual revenue. Setup is relatively straightforward. Field exam requirements are standard. These facilities are often used as bank line replacements for growing businesses that have outgrown factoring or cannot get adequate bank credit.

Middle market ($5M–$25M): These facilities serve businesses with $10–$75 million in annual revenue. Reporting requirements are more detailed, field exams more comprehensive, and the legal documentation more complex. The economics are better for the borrower — lower rates and higher availability relative to asset values — because the lender spreads fixed costs over a larger facility.

Upper middle market ($25M–$50M+): Facilities at this level typically involve multiple lenders (syndicated facilities), more extensive due diligence, and detailed ongoing monitoring. These are beyond the typical referral partner's client base but important to understand for context.

The minimum viable deal size for ABL is driven by economics: the field exam costs, legal setup costs, and monitoring overhead mean that a $500,000 ABL facility would have a disproportionately high cost relative to its benefit. The $1 million minimum is a practical floor, though some specialty ABL lenders work with smaller facilities. For businesses below the ABL minimum, factoring is the appropriate alternative.

Industries That Use ABL Most

Manufacturing

Manufacturers have the most complete ABL collateral base: receivables from customer shipments and inventory at multiple stages (raw materials, WIP, finished goods). ABL allows manufacturers to borrow against the full asset cycle and provides working capital that scales with production volume and order book.

Wholesale distribution

Distributors hold significant inventory to fill customer orders and generate receivables as they sell. ABL against both receivables and inventory provides the revolving capital needed to keep inventory stocked and receivables funded. Distribution is one of the most natural ABL industries.

Retail (larger businesses)

Larger retailers with significant inventory holdings can use ABL against inventory value. Seasonal retailers — those who need to build inventory for peak selling periods — use ABL to fund those inventory builds, drawing on the line before the season and repaying as sales convert inventory to cash.

Staffing (at scale)

Staffing companies with large receivables portfolios often graduate from factoring to ABL as they grow. The economics of ABL improve significantly at higher volumes, and larger staffing companies have the finance staff to manage borrowing base reporting without the outsourced collections overhead that factoring involves.

Business services

B2B service companies with large receivables portfolios — technology services, engineering firms, marketing agencies — can use ABL against their receivables. These businesses typically have minimal inventory, so the facility is receivables-only ABL, but the revolving nature still provides significant flexibility over a term loan.

Turnaround situations

Businesses going through financial difficulty — restructuring, bankruptcy emergence, loss of bank credit — often use ABL as a bridge or replacement credit facility because qualification is asset-based rather than requiring positive historical profitability. ABL lenders are generally more comfortable with distressed situations than conventional banks.

When to Refer ABL vs. Factoring vs. Working Capital Loan

The routing decision between ABL, factoring, and working capital products is one of the most important judgment calls for referral partners. Getting it right serves clients better and leads to higher conversion rates — deals land in the right structure rather than requiring re-routing after initial decline.

Client profile Route to Key reason
$2M+ annual receivables, wants to maintain customer relationships, has finance staff ABL Scale and relationship-management preference justify ABL infrastructure; lower cost than factoring at volume
Under $2M receivables, consistent B2B invoice volume, needs collections outsourced Invoice factoring Below ABL minimum; factoring provides accessible entry point without complex reporting
Significant inventory alongside receivables (manufacturer or distributor) ABL (receivables + inventory) Inventory advance component not available in factoring; ABL captures full collateral value
Short-term, fixed capital need (not driven by ongoing receivables cycle) Working capital loan or term loan ABL and factoring are ongoing facilities — not the right structure for one-time capital needs
Business in financial distress, bank line lost, has assets ABL (distressed) ABL lenders more tolerant of distress than conventional banks; asset-based qualification

Referral Process for ABL Deals

ABL deals require more initial information than simpler products because the lender must evaluate asset quality and business operations before proposing a facility structure. Key information needed for an ABL referral:

  • Accounts receivable aging report — detailed listing of all outstanding invoices by customer, age, and amount
  • Inventory report by category — raw materials, WIP, finished goods, with values at cost
  • Recent financial statements — last 2–3 years of income statements and balance sheets (audited or reviewed preferred)
  • Recent bank statements — 3–6 months
  • Customer and vendor concentration — who are the top customers and suppliers, and what percentage of revenue/purchases do they represent?
  • Existing lien information — current UCC filings, outstanding bank debt, existing pledges on assets
  • Description of the need — what is the facility replacing or supplementing? What is the use of funds?
1

Sign the referral agreement

The referral partner reviews and signs the referral agreement with Axiant Partners before submitting deals. This establishes fee structure and the referral relationship scope.

2

Submit the deal

Provide the AR aging, inventory report, financial statements, and situation description via the referral form or directly by email.

3

Initial evaluation and LOI

ABL evaluation focuses on asset quality, concentration, industry, and proposed facility structure. An initial letter of intent or term sheet outlines the proposed facility terms, advance rates, and fees.

4

Field exam and due diligence

After client acceptance of terms, the lender conducts the initial field examination and legal due diligence. This phase typically takes 2–4 weeks for standard deals.

5

Closing and funding

The facility is documented, UCC filings made, and the initial draw is funded. The referral partner is notified and the referral fee is paid per the agreement.

FAQ

Questions about asset-based lending

What is asset-based lending and how does it differ from a conventional business loan?

ABL is a revolving credit line where borrowing capacity is tied to the value of specific business assets — primarily receivables and inventory. A conventional loan provides a fixed amount based on creditworthiness and cash flow. ABL availability fluctuates with asset values, making it more flexible for businesses with variable working capital needs. Qualification is asset-driven, not primarily credit-driven.

How does the borrowing base work in an ABL facility?

The borrowing base applies advance rates to eligible assets: typically 80–85% of eligible receivables and 50–65% of eligible inventory. The sum is the maximum the business can borrow at any time. It fluctuates daily as receivables are generated and collected and inventory is purchased and sold. Borrowing base certificates are submitted weekly or monthly to update availability.

What is a field exam in asset-based lending?

A field exam is a formal audit of the borrower's books, records, and physical assets conducted by the lender's auditors. Conducted at origination and annually (or more frequently if needed), field exams verify that receivables are real and accurately reported and that inventory exists as stated. Costs of $1,500–$5,000 per exam are borne by the borrower.

What deal sizes and industries does ABL serve?

ABL facilities typically start at $1 million and extend to $50 million or more for mid-market businesses. Industries: manufacturing, wholesale distribution, retail, staffing, and B2B services. The common thread is businesses with significant, recurring receivables and/or inventory that need revolving credit tied to working capital assets.

When should a referral partner route a client to ABL vs. factoring vs. working capital loan?

Route to ABL when the client has $1M+ in receivables, wants to maintain customer relationships, and has finance staff for reporting. Route to factoring when below ABL minimum or collections outsourcing is needed. Route to a working capital loan when the need is short-term, fixed-amount, and not driven by the ongoing receivables cycle.

Have a manufacturer, distributor, or staffing company that needs a revolving credit line?
