SBA CAPLines: The 7(a) Revolving Line of Credit for Working Capital

SBA CAPLines: The 7(a) Revolving Line of Credit for Working Capital — The Ledger by MidBank

CAPLines is a set of four revolving and non-revolving lines of credit offered under the SBA 7(a) program to finance short-term and seasonal working-capital needs — not fixed assets. You borrow against assets like receivables, inventory, or a specific contract, draw as you need cash, and repay as those assets convert back to cash. It carries the same guaranty, maximum loan size, and personal-guarantee rules as a standard 7(a) loan, but the money is tied to a revolving need rather than a one-time purchase.

Most owners meet the SBA through a term loan — a lump sum to buy a business, equipment, or real estate. But a lot of small businesses don't have a lump-sum problem. They have a timing problem: payroll is due Friday, the customer pays in 60 days, and the gap between the two is where cash flow goes to die. CAPLines is the SBA's answer to that gap.

CAPLines is not a separate loan program. It is a line of credit delivered under the 7(a) umbrella, which means it inherits the 7(a) guaranty, the 7(a) maximum loan amount, and the 7(a) personal-guarantee and fee structure. What's different is the shape of the money: instead of one disbursement, you get a credit line you draw against and pay down as your business cycles through its working-capital needs.

The direct answer: what CAPLines actually is

CAPLines finances working capital and short-term, cyclical needs — the cost of producing and carrying goods and services until the customer pays. It is designed around assets that turn into cash: accounts receivable, inventory, and work in progress on a contract or construction project. It is not for buying a building, refinancing long-term debt for the sake of it, or funding a permanent increase in your fixed assets.

The SBA offers four distinct CAPLines, and the one you need depends on why your cash is tied up.

The four types of CAPLines

Each type answers a different version of the same question: what do I have to pay for today that a known future payment will cover?

How the money moves — and why the borrowing base matters

A CAPLine is not a pile of cash sitting in your account. On the Working Capital and Contract lines in particular, your available credit is governed by a borrowing base: the lender advances only a percentage of your eligible collateral, and you certify that collateral periodically. If your eligible receivables shrink — a big customer pays late, or an invoice ages past the eligibility window — your available draw shrinks with it, even if your credit limit on paper is higher.

This is the single biggest conceptual shift from a term loan. With a term loan, you qualify once and the money is yours. With a CAPLine, you re-qualify every reporting period through the borrowing base. That is a feature, not a bug — it keeps the line sized to the real need — but it surprises owners who expected a fixed, always-available amount. If you want the mechanics of how lenders calculate advance rates and knock out ineligible collateral, our deep dive on the borrowing base certificate walks through it line by line.

Revolving vs. non-revolving

Not every CAPLine revolves. A Working Capital or Seasonal line typically revolves — pay it down and you can draw again. A Contract or Builders line is often non-revolving or tied to the life of the specific project, because the underlying collateral is a one-time job, not an ongoing cycle. Confirm which structure you're signing, because it changes how you plan repayment.

What CAPLines shares with a standard 7(a) loan

Because CAPLines lives under the 7(a) program, several of the rules you may already know carry straight over:

What's different is maturity. A CAPLine is a working-capital tool, so its term is shorter than the 10-to-25-year horizons you see on 7(a) real-estate or acquisition loans. CAPLines carry a maximum maturity of up to 10 years, and in practice many are set shorter and renewed. For the full range of how the program sets terms, see how SBA loan terms work.

Where CAPLines fits — and where it doesn't

CAPLines is a strong fit when your cash is predictably tied up in assets that convert back to cash: receivables you'll collect, inventory you'll sell, a contract you'll complete. It is a poor fit, and the SBA will treat it as ineligible, when you're really trying to finance a permanent need — buying equipment, acquiring real estate, or plugging an operating loss that never reverses.

A simple test: if the thing you're financing will turn into cash on a known timeline, a line like CAPLines is built for it. If the thing you're financing is a long-term asset or a structural shortfall, you're looking at the wrong product. The broader comparison between a revolving line and a working-capital term loan is laid out in working capital vs. line of credit, and it's worth reading before you ask a lender for either.

The traps borrowers miss

CAPLines is useful, but it carries a few sharp edges that a first-time line-of-credit borrower rarely sees coming:

The takeaway

CAPLines is the SBA's working-capital line of credit, delivered through the 7(a) program in four flavors — Working Capital, Contract, Seasonal, and Builders — each matched to a different reason your cash is tied up. It brings the 7(a) guaranty and structure to a revolving need instead of a one-time purchase. The upside is a government-backed line sized to real collateral. The discipline is that the line is only as large as your eligible assets, it has to be reported on, and it may have to rest. Used for what it's built for — the gap between doing the work and getting paid — it's one of the more honest financing tools a small business can carry.

Questions business owners actually ask

What is the difference between CAPLines and a regular SBA 7(a) loan?

A standard 7(a) loan is usually a lump-sum term loan for a defined purchase — a business, equipment, or real estate. CAPLines is a line of credit under the same 7(a) program, built for short-term and seasonal working capital. You draw and repay as your receivables, inventory, or a contract cycle through cash, rather than receiving one fixed disbursement.

How many types of CAPLines are there?

Four: the Working Capital CAPLine (secured by receivables and inventory), the Contract CAPLine (tied to specific assignable contracts), the Seasonal CAPLine (for predictable seasonal build-ups), and the Builders CAPLine (for constructing or renovating a specific building for resale).

Can I use a CAPLine to buy equipment or real estate?

No. CAPLines finances short-term, cyclical working-capital needs — the cost of carrying goods and services until a customer pays. Buying fixed assets like equipment or real estate is a different use of proceeds and typically calls for a standard 7(a) term loan or a 504 loan instead.

Do I still have to sign a personal guarantee on a CAPLine?

Yes. Because CAPLines runs under the 7(a) program, the SBA requires an unconditional personal guarantee from every owner holding 20% or more of the business, just as it does on any other 7(a) loan.

Why did my available credit drop even though my limit didn't change?

CAPLines draws are often governed by a borrowing base — a percentage of your eligible receivables and inventory. If a customer pays late or an invoice ages out of eligibility, your eligible collateral shrinks, and your available draw falls with it even though the stated credit limit is unchanged.

How long is a CAPLine good for?

CAPLines carries a maximum maturity of up to 10 years, shorter than the long terms on 7(a) real-estate or acquisition loans. Many lines are set shorter than the maximum and re-underwritten at renewal, so renewal is not automatic.
