Business Line of Credit: A Practical Guide for Owners & Bookkeepers

· 8 min read

A business line of credit (LOC) is one of the most flexible financing tools available, but its mechanics can be tricky. It lets you borrow up to a set limit, repay, and borrow again, paying interest only on what you use. It's ideal for smoothing cash flow, bridging accounts receivable gaps, and handling other short-term needs.

However, navigating secured vs. unsecured lines, variable rates, hidden fees, and tax implications is crucial. This guide breaks down everything owners and bookkeepers need to know, complete with practical examples for tracking it all in Beancount.

What a Business Line of Credit Is (and Isn’t)

Think of a business line of credit as revolving working capital. It’s a preset credit limit you can draw from whenever you need funds. Once you repay the borrowed amount, your available credit is restored, ready to be used again. The simplest analogy is: “credit card mechanics, business-loan pricing.”

This makes it fundamentally different from a term loan. A term loan provides a lump sum of cash upfront, which you repay over a fixed period through regular installments. LOCs are built for flexibility and short-term cash cycle management, whereas term loans are better suited for large, long-term investments like purchasing equipment or real estate.


When an LOC Makes Sense

A line of credit shines in specific, recurring business scenarios:

  • Bridging Receivables and Inventory Cycles: This is the classic use case. You can draw from your LOC to pay suppliers for inventory and then repay the line weeks or months later when your customers pay their invoices. It’s a perfect tool for wholesalers, agencies, and seasonal businesses that face predictable cash flow gaps.
  • Emergency Buffer: Unexpected expenses are inevitable. An LOC acts as a ready-to-draw backstop for covering a payroll shortfall, funding an emergency repair, or managing a sudden operational need. It’s far more efficient than applying for a new loan every time a surprise occurs.
  • Opportunistic Buying: Did a key supplier offer a significant discount for early payment? You can use your LOC to seize the opportunity, capture the savings, and repay the draw once your own cash flow catches up.

Secured vs. Unsecured (Read the Lien Language)

Lenders need assurance they’ll be repaid, which is why most lines of credit are secured by collateral.

  • Secured Lines: Many bank LOCs are secured by specific assets, like your accounts receivable or inventory. More commonly, a lender will place a blanket UCC lien on the business. This gives the lender a claim on most of your business assets in the event of a default. It is critical to read the security agreement and confirm if any key assets (like intellectual property) are excluded assets.
  • Unsecured Lines: These are harder to qualify for, typically come with lower limits and higher interest rates, and are reserved for businesses with stellar credit. They don't require you to pledge specific collateral, but many lenders will still require a personal guarantee from the owner.
  • SBA Options: For U.S. borrowers, the Small Business Administration (SBA) offers programs like the 7(a) Working Capital Pilot (WCP) for monitored lines of credit and CAPLines, which are asset-based revolvers tied directly to short-term working capital needs.

Practical Tip: Always ask the lender to spell out any carve-outs in the lien agreement. "Excluded assets" clauses are negotiable and can prevent a blanket lien from interfering with other financing, like an equipment loan.


How Costs Work (Rates + Fees)

The cost of an LOC isn't just the interest rate. You must account for a variety of potential fees.

  • Interest: You are only charged interest on the drawn amount. Rates are typically variable, calculated as a benchmark rate (like the Prime Rate) plus a margin (e.g., Prime + 1.5%). As you repay the principal, your interest cost decreases and your credit availability is restored.
  • Fees to Watch For:
    • Origination Fee: A one-time fee charged when you open the line.
    • Annual or Monthly Maintenance Fee: A recurring charge to keep the line open, sometimes called a non-usage fee if you don't draw from it.
    • Draw Fee: A fee charged each time you take funds from the line.

These costs add up. Before committing, model your expected usage to find the true cost.

Back-of-the-Envelope Example

Let's say you have a 100,000limitanddraw100,000** limit and draw **40,000 for two months at 12% APR. The line has a 2% draw fee and a $150 annual fee.

  • Interest40,000×1240,000 × 12% × (2/12) = **800**
  • Draw Fee = 2% × 40,000=40,000 = **800**
  • Annual Fee = $150
  • Total Cost$1,750

In this scenario, the fees make the effective cost significantly higher than the headline 12% APR.


Qualifying and Staying in Good Standing

Lenders evaluate your business's health based on revenue consistency, time in business, and both business and personal credit scores. Building a strong history of on-time payments is the best way to gain access to better terms and lower rates.

Most LOCs aren't "set it and forget it." They often require annual renewal, where the lender reviews updated financial statements. Your agreement may also include financial covenants, such as maintaining a minimum Debt Service Coverage Ratio (DSCR) or interest coverage ratio. If your financial metrics slip, the lender has the right to reduce your limit or freeze the line entirely.


LOC vs. Term Loan vs. Credit Card

Choose the right tool for the job:

ToolBest Use Case
Business Line of CreditRepeatable, short-term working capital swings and opportunistic buys you can repay quickly.
Term LoanOne-time purchases of long-life assets like machinery, vehicles, or real estate.
Business Credit CardSmall, frequent purchases where you can earn rewards. Watch the high interest rates.

A Note on U.S. Taxes

Interest paid on a business line of credit is generally a deductible business expense. However, under Section 163(j) of the tax code, this deduction may be capped.

A small-business exception exists for companies whose average annual gross receipts for the prior three years fall below an inflation-adjusted threshold (around 30millionfor2024and30 million for 2024** and **31 million for 2025). Always confirm the specifics with your tax advisor, as these rules are complex.


Beancount: How to Record a Line of Credit

Tracking an LOC in a plain-text ledger like Beancount ensures clarity and accuracy. Below are illustrative examples of the key transactions. (Note: In Beancount, increasing a liability uses a negative amount, while repaying it uses a positive amount).

1. Open Accounts & Document the Facility

First, set up the necessary accounts in your ledger. It's a best practice to add a note with the LOC's key terms.

2025-01-01 open Assets:Bank:Operating         USD
2025-01-01 open Liabilities:LOC:BigBank USD
2025-01-01 open Expenses:Interest:LOC USD
2025-01-01 open Expenses:BankFees USD

; Optional: Document the facility's terms with a note
2025-01-01 note Liabilities:LOC:BigBank "Limit=100000, Rate=Prime+1.50%, Secured by A/R & Inventory (UCC-1)"

2. Draw Funds

When you transfer funds from the LOC to your operating account, you increase cash and increase the liability.

2025-03-03 * "Draw from LOC to cover receivables timing"
Assets:Bank:Operating 40000.00 USD
Liabilities:LOC:BigBank -40000.00 USD

3. Accrue Monthly Interest

At the end of the month, record the interest incurred as an expense, which adds to the total amount you owe.

2025-03-31 * "Accrue LOC interest for March"
Expenses:Interest:LOC 800.00 USD
Liabilities:LOC:BigBank -800.00 USD

4. Record a Draw Fee or Maintenance Fee

Book any fees as an expense, paid from your operating account.

2025-03-31 * "LOC draw fee (2%)"
Expenses:BankFees 800.00 USD
Assets:Bank:Operating -800.00 USD

5. Make a Payment (Interest + Principal)

A payment reduces your operating cash and reduces the liability balance.

2025-04-10 * "LOC payment (principal + interest)"
Liabilities:LOC:BigBank 10800.00 USD
Assets:Bank:Operating -10800.00 USD

Due Diligence & Negotiation Checklist

Before you sign, get clear answers to these questions:

  • Fees: Request a full fee table: origination, annual/maintenance, inactivity, draw, and wire/ACH fees.
  • Renewal: What is the renewal process? What could trigger a limit reduction or a freeze?
  • Lien Scope: What specific assets are covered by the lien? Are there any exclusions?
  • Covenants: Are there financial covenants like DSCR? How often are they tested, and what happens if you temporarily fall short?
  • SBA Terms: If it's an SBA-backed line, is it a WCP or CAPLines facility? How is your borrowing base calculated and reported?

Final Word

A well-structured line of credit is an invaluable tool for managing a growing business. The key is to fully understand the collateral you're pledging, the total cost including all fees, and the obligations required to keep the line in good standing.

By keeping a clean ledger in Beancount with clear metadata, you can track your usage, understand its true cost, and ensure this flexible tool remains a powerful asset for your business.

If you want flexible working capital you can draw, repay, and reuse, a business line of credit (LOC) beats taking repeated term loans. Below are this year’s strongest options by use‑case, plus a quick way to compare costs and a simple Beancount recipe for recording draws, interest, and fees.

TL;DR — Best‑fit picks by scenario

  • Fast, flexible fintech line: Bluevine — up to $250k, weekly or monthly repayment, funding often within 24 hours, rates advertised “as low as 7.8% (simple interest).”
  • Fee‑based draws with multiple terms: American Express Business Blueprint® Line of Credit — line sizes 2k2k–250k; choose 1–3‑month single‑repayment loans or 6–24‑month installment loans with fixed loan fees (not APR).
  • Prime‑based bank line with clear pricing: Wells Fargo BusinessLine® / Prime Line — BusinessLine: Prime + 1.75% to +9.75%; Prime Line: Prime + 0.50% (floor 5%); typical credit limits 10k10k–150k.
  • Relationship pricing & a way to “graduate”: Bank of America — unsecured Business Advantage line (relationship discounts 0.25–0.75%); or Cash‑Secured line where your deposit sets the limit (from $1,000), helpful to build business credit.
  • Branch + national reach: Chase Business Line of Credit — online up to $250k, 5‑year revolving period then 5‑year repayment (available in 48 states).
  • **Up to 250kwithclearannualfeepolicy:U.S.BankCashFlowManagerlinesto250k with clear annual fee policy:** **U.S. Bank Cash Flow Manager** — lines to 250k; unsecured option to 100k;noannualfeeifline100k; no annual fee if line \> 50k (otherwise $150).
  • Newer businesses that need speed (know the cost): Headway Capital5k5k–100k, calculator shows starting ~3.3% monthly + 2% draw fee.
  • Fast approvals but typically expensive: OnDeck LOC — up to $200k; company‑reported average APR ~56.6% for lines (H1’25).
  • For bigger, lower‑rate, monitored lines (if you qualify): SBA lines — classic CAPLines umbrella programs and the newer 7(a) Working Capital Pilot (WCP). WCP lets lenders issue monitored revolving lines up to $5M with an SBA guaranty.

What changed or matters in 2025? 📈

Two key trends are shaping the business credit landscape this year:

  1. Prime settled lower than 2023 highs. The Wall Street Journal Prime Rate is 7.50% (as of September 2, 2025), last changed on December 19, 2024. This is the benchmark rate that directly feeds the pricing for most variable-rate bank lines of credit (which are typically priced as "Prime + a margin"). A stable, lower Prime Rate means more predictable costs for borrowers.
  2. SBA rolled out/expanded monitored working‑capital lines. The 7(a) Working Capital Pilot (WCP) program, effective August 1, 2024, continues to expand. It enables lenders to issue asset- or transaction-based monitored LOCs, which is a huge help for businesses needing financing for inventory, receivables, or specific contracts.

How to choose the right LOC (7 quick checks) ✅

  1. Index & Margin: If it’s a bank line priced as "Prime ± X%", check today’s Prime Rate (7.50%) and add the margin you’re offered. That’s your current variable Annual Percentage Rate (APR).
  2. Fee‑based vs. Interest‑based: Some fintechs (like AmEx Blueprint) charge a fixed "loan fee" per draw instead of interest. Compare the effective APR of that fee to interest-based offers before deciding.
  3. Annual/Draw Fees: These add to your total cost, especially if you use the line infrequently. U.S. Bank waives its 150annualfeeforlinesover150 annual fee for lines over 50k, while PNC lists a $175 fee for its unsecured LOC.
  4. Repayment Cadence: Weekly payments (common with online lenders) can smooth out cash flow but require more frequent management. Monthly payments simplify bookkeeping. Bluevine offers both weekly and monthly options.
  5. Funding Speed: If you need cash now, speed is critical. Bluevine often funds within 24 hours, and American Express offers instant deposits on draws to an AmEx Business Checking account.
  6. Eligibility & Graduation Path: If you can't qualify for an unsecured line yet, a product like Bank of America’s cash‑secured line (starting at $1,000) can help you build business credit and "graduate" to an unsecured line later.
  7. Consider SBA for Size or Structure: For larger needs tied to inventory, receivables, or contracts, the SBA's 7(a) WCP or CAPLines programs can provide larger, monitored lines at regulated rates, provided you can handle the more in-depth underwriting.

A quick cost comparison tip 🧮

Comparing offers can be tricky. Here's a simple way to think about it:

  • Prime‑based example: If a bank offers you Prime + 2.75%, your starting APR today is 10.25% (7.50% + 2.75%). Remember, this rate will float up or down if the Prime Rate changes.
  • Fee‑based example (AmEx Blueprint): A 12-month draw with a 6–18% total loan fee might seem low. However, to compare apples-to-apples, you must compute the equivalent APR on the amortizing balance. A fixed fee on the initial draw amount is not the same as an APR on a declining balance.

Beancount: How to record a line of credit

For users of the plain-text accounting tool Beancount, tracking a line of credit is straightforward. The LOC is a liability; draws increase that liability and your cash, while interest and fees are expenses. Replace the account names below to match your own ledger.

1) Draw $25,000 from your LOC to your checking account

2025-03-15 * "LOC draw"
Assets:Bank:Checking 25,000.00 USD
Liabilities:LOC:Bluevine -25,000.00 USD

2) Make a 2,300payment(2,300 payment (300 interest, $2,000 principal)

2025-04-15 * "LOC payment (principal + interest)"
Liabilities:LOC:Bluevine 2,000.00 USD
Expenses:Interest:LOC 300.00 USD
Assets:Bank:Checking -2,300.00 USD

3) Record a $150 annual fee charged to your bank account

2025-01-10 * "Annual LOC fee"
Expenses:BankFees:LOC 150.00 USD
Assets:Bank:Checking -150.00 USD

Alternative: If the annual fee is added to the line's balance instead of being debited from your bank account, the transaction would be:

2025-01-10 * "Annual LOC fee added to balance"
Expenses:BankFees:LOC 150.00 USD
Liabilities:LOC:Bluevine -150.00 USD

When an SBA-backed line makes more sense

An SBA-guaranteed line isn't for everyone, but it's a powerful tool if:

  • You need a bigger credit limit than what most fintech or bank unsecured products offer.
  • Your working capital needs are tied to collateral like accounts receivable (A/R), inventory, or signed contracts.
  • You can handle the monitoring requirements, such as submitting borrowing base certificates and regular financial reporting.

If this sounds like your business, look into the SBA CAPLines programs and the 7(a) Working Capital Pilot (WCP). These programs can facilitate lines up to $5M, and standard CAPLines can have maturities of up to 10 years.


Application checklist 📝

Be prepared. Most lenders will ask for the following:

  • Time in business, revenue, and credit score: Banks typically want 1–2+ years in business and stronger credit, while many online lenders have more flexible criteria but price for the added risk.
  • Financials: Have your recent bank statements, business tax returns, and potentially A/R aging or inventory reports ready.
  • Personal Guaranty: This is a standard requirement for most business lines of credit. It means you are personally responsible for repaying the debt if the business cannot.

Key sources


Final word

A line of credit is about control: draw what you need, when you need it. In 2025, Prime-based bank lines remain attractive for those who qualify, while fintech lines trade higher costs for incredible speed and flexibility. For larger, more complex needs, SBA-backed lines unlock structured facilities. The key is to run the numbers (always convert fees to an effective APR), understand the fee structure, and pick a repayment schedule that keeps your business financially healthy—and your Beancount ledger clean.
