Your busy season is eight weeks away, and the math does not work. You need $120,000 of inventory on the shelves and two extra crew members on payroll before the first dollar of seasonal revenue arrives. A term loan would solve October and punish you all next year with fixed payments on money you only needed for a quarter. This is the exact problem the SBA's CAPLines program was built for: government-guaranteed lines of credit, up to $5 million, shaped around the way short-term cash needs actually arrive — in seasons, in contracts, in construction draws, and in the gap between shipping goods and getting paid.
CAPLines is an umbrella inside the SBA's flagship 7(a) loan program. The SBA does not lend to you directly. Instead, approved lenders — banks and credit unions — extend the line, and the SBA guarantees a large share of it, which is what makes lenders willing to offer revolving credit to smaller businesses at reasonable rates and terms. The umbrella holds four distinct lines, each with its own eligibility rules, collateral, and repayment shape. Picking the right one matters, because you generally get one: a business typically qualifies for the single CAPLine that matches its primary model, not a stack of them. This guide walks through all four, what each costs and demands, and how to keep books that survive a lender's review.
How CAPLines Work: The Shared Foundation
Before the four lines diverge, they share one foundation, because all of them live under 7(a) rules.
It is revolving credit, not a lump sum. You draw up to an approved limit, pay interest only on the outstanding balance, and repayments restore your capacity to borrow again. That structure fits fluctuating needs — inventory builds, contract ramps, receivable gaps — far better than a term loan's fixed monthly payment.
The guarantee is what buys you the terms. The SBA guarantees 85 percent of lines up to $150,000 and 75 percent of larger lines, up to the $5 million program ceiling. That guarantee is why a lender will extend multi-year revolving credit to a business that could never get the same line conventionally.
Rates follow 7(a) rules. Interest is typically variable, set as the prime rate plus a spread you negotiate with the lender, subject to SBA maximums. Rates can be fixed or variable depending on the lender and the line.
Terms run long for credit lines. Most CAPLines can run up to 10 years — far longer than the one-to-two-year renewals typical of conventional bank lines. The Builders line is the exception, capped at five years to match project timelines.
Standard 7(a) eligibility applies to all four. Your business must be for-profit, operate in the United States, meet the SBA's size standards, and meet the "credit elsewhere" test — meaning you cannot get comparable credit on reasonable terms without the guarantee. Expect the lender to look for a personal credit score around 680 or higher from the owners, collateral securing the line, and personal guarantees from every owner with 20 percent or more equity.
With that foundation in place, here is where the four lines split.
Seasonal CAPLine: Borrowing Against Next Season's Revenue
Best for: businesses with predictable annual peaks and valleys — holiday retailers, landscapers, tourism operators, agricultural suppliers.
A Seasonal CAPLine finances the build-up before your busy period: the inventory you must stock, the receivables that will pile up during peak sales, and in some cases the extra labor costs the season demands. You draw as the season approaches and repay as seasonal revenue comes in, with the line typically structured around your annual cycle even though the maturity can extend up to 10 years for established seasonal patterns.
Qualifying takes proof of rhythm. Beyond standard 7(a) eligibility, your business generally must have operated for at least a year and must demonstrate a clear pattern of seasonal activity — lenders want to see the peaks and valleys in your history, not just hear about them in a projection. The loan amount follows your cash-flow projections for the seasonal cycle.
The discipline that makes or breaks this line is the paydown. A seasonal line that never fully revolves — that stays drawn through the slow months — stops looking like seasonal financing and starts looking like a permanent loan wearing a costume. Lenders notice. Before you apply, be sure your slow-season cash flow can carry the business with the line at or near zero.
Contract CAPLine: Financing the Work You Have Already Won
Best for: businesses fulfilling specific contracts, subcontracts, or purchase orders — government contractors, project-based services, and suppliers with large committed orders.
A Contract CAPLine funds the cost of performing work you have already sold: materials, supplies, labor, and overhead tied to the contract. One line can finance a single contract or multiple contracts, and the contract itself — more precisely, the proceeds it will pay — serves as the primary collateral. As you complete work and invoice the customer, payments are commonly directed to the lender to pay the line down.
Two requirements define this line. First, you need a signed contract or purchase order in hand; this is financing for won work, not for chasing it. Second, the contract must generally be assignable, meaning its payments can legally be directed to the lender — the assignment of proceeds is the mechanism that makes the whole structure safe for the bank. Lenders also typically want evidence that you performed profitably on previous contracts, since the underwriting rests on your ability to deliver this one on budget.
Repayment follows the contract's own timeline: the line is paid down as contract payments arrive, with maturities up to 10 years for longer performance periods. Proceeds can cover contract costs but not profit distributions — the line finances performance, not the reward for it.
Builders CAPLine: Draw-by-Draw Financing for Construction
Best for: small general contractors and developers building or rehabilitating residential or commercial property for resale.
The Builders CAPLine finances direct project costs — land acquisition when it is part of the project, labor, materials, and permits — through a draw schedule. You request funds as the project hits stages of completion, the lender verifies progress (usually by inspection) before releasing each draw, and the property under construction serves as the primary collateral. The full balance is repaid when the project completes and sells.
The guardrails here are tighter than on the other three lines, and deliberately so:
- Shorter maximum term. Five years (60 months), not ten — the line is meant to match project cycles, and the balance is generally due within 36 months of project completion or upon sale of the property, whichever comes first.
- Restricted use of funds. Proceeds go to work on the structure itself, plus utility connections and landscaping — not to unrelated business spending.
- Track record required. The builder must show a history of completed projects and the ability to manage construction budgets, because the lender is underwriting your execution as much as the property.
If you build on speculation or take on renovation-for-resale work, this is the only CAPLine shaped like your cash flow: large outflows during construction, one large inflow at sale, and nothing in between that could service a term loan.
Working Capital CAPLine: An Asset-Based Line for the Everyday Gap
Best for: businesses with cash permanently tied up in receivables and inventory — manufacturers, wholesalers, distributors.
The Working Capital CAPLine is the general-purpose member of the family: a revolving line that finances short-term operating needs against the assets already on your balance sheet. Your available credit is set by a borrowing base — typically an advance rate against eligible accounts receivable plus a smaller advance rate against eligible inventory. A common shape is around 80 percent of receivables under 90 days old plus around 50 percent of finished-goods inventory, minus reserves the lender requires. As your receivables and inventory rise and fall, so does your available credit.
That flexibility comes with the heaviest record-keeping of the four lines. Because availability is computed from your assets, the lender monitors your collateral continuously — usually through monthly borrowing-base certificates reconciling your receivables aging, payables, and inventory reports. Some lenders charge additional monitoring fees for this oversight, so price them into your comparison. Maturities run up to 10 years, making this a durable facility for businesses whose cash conversion cycle never really closes.
One history note worth knowing: this line absorbed what used to be two separate asset-based programs. An older SBA overhaul folded the standard asset-based line into the Working Capital CAPLine and retired the small asset-based variant, so if you encounter old references to "Standard Asset-Based CAPLines," they mean this line under its former name.
The One-Line-at-a-Time Limit
A natural question: can you hold two CAPLines at once — say, a Seasonal line for the holiday build plus a Contract line for a big order? Generally, no. Lenders and the SBA steer each business to the single CAPLine that fits its primary model and financing need. A contractor uses the Builders line for its projects rather than layering a Contract line on top; a seasonal retailer uses the Seasonal line rather than adding a Working Capital line beside it.
This is a program-design choice, not just lender preference. Each CAPLine's collateral, monitoring, and repayment structure assumes it is the facility financing that slice of your working capital, and overlapping lines would muddy which collateral secures which advance. If your needs genuinely span two shapes — seasonal sales plus contract work, for example — discuss it with your lender up front; the answer is usually one line sized and structured to cover the dominant need, not two parallel facilities.
What CAPLines Cost Beyond the Interest Rate
The rate gets the attention, but four other costs shape the real price:
- The SBA guarantee fee. Charged up front on the guaranteed portion, this fee can often be rolled into the loan amount rather than paid out of pocket — but it is still part of your cost.
- Lender service fees. Expect an annual servicing fee from the lender on top of interest.
- Collateral monitoring fees. Most relevant to the asset-based Working Capital line, where continuous borrowing-base monitoring takes lender staff time.
- Your own compliance time. Monthly certificates, annual renewals with fresh financials, draw inspections on Builders lines, assignment paperwork on Contract lines. None of these carry an invoice, but all of them consume hours — price them honestly when comparing against a simpler conventional line.
None of this makes CAPLines expensive relative to the alternatives. A conventional line of similar size typically renews annually, carries a higher rate, and demands stronger financials. The CAPLine trade is clear: lower financial cost and longer terms in exchange for more paperwork and closer lender oversight.
How to Apply: Documents, Timeline, and Approval Realities
Start with an SBA-approved lender experienced in CAPLines specifically — not every 7(a) lender handles them regularly, and the type-specific rules reward experience. The SBA's Lender Match tool can surface participating lenders in your area.
The documentation package is extensive. Expect to provide several years of business and personal tax returns, profit-and-loss statements and balance sheets, a business plan, a schedule of existing debts — plus type-specific evidence: signed contracts or purchase orders for a Contract line, seasonal sales history for a Seasonal line, project plans and budgets for a Builders line, receivables aging and inventory reports for a Working Capital line.
Timelines run longer than conventional credit. Between the lender's underwriting and the SBA's review, approval commonly takes weeks to a couple of months, so apply well before the need arrives — the seasonal retailer applies in spring, not October. And be ready for questions: underwriters routinely come back for clarification on projections, collateral, and cash-flow assumptions.
Keep Books a Lender Can Underwrite
Every CAPLine in this guide is ultimately underwritten twice: once at approval, and then continuously through monitoring. Seasonal lines need credible cash-flow projections by month. Contract lines need job costing clean enough to prove each contract's profitability. Builders lines need draw documentation tied to verified progress. Working Capital lines need monthly receivables aging, payables aging, and inventory reports accurate enough to set your borrowing limit.
That is a bookkeeping standard most small businesses do not meet on day one — and the fix is cheaper than the scramble. Reconcile receivables and inventory monthly, keep contract costs separated by job, and keep owner draws distinct from business expenses, so that when a lender asks for a borrowing-base certificate or a seasonal history, the answer already exists in your books. If you want a system where every balance is derived from explicit, reviewable entries rather than a black-box ledger, the docs walk through getting started with plain-text accounting.
CAPLines vs. the Other SBA Credit Options
Two nearby programs cause the most confusion. SBA Express lines (up to $500,000, 50 percent guarantee) fund faster with less paperwork but cap out far below CAPLines' $5 million — pick Express for speed on smaller needs. The 7(a) Working Capital Pilot, launched in 2024, offers asset- and transaction-based lines with more modern collateral rules, but it runs as a time-limited pilot while CAPLines is the permanent, purpose-built program. None of these is strictly better; they answer different questions, and your lender can tell you which window is open for your situation.
