Should a small business borrow a lump sum or open a line of credit?

Summary

A lump sum fits a cost that is known in advance and an asset that outlasts the repayment, and a line of credit fits a need that rises and falls with inventory, receivables, or seasons. SBA's own programs split the same way: 504 loans cannot pay for working capital or inventory, and revolving lines inside 7(a) are allowed only under SBA Express, Export Express, CAPLines, and the Working Capital Pilot. The price of a line's flexibility is monitoring: SBA's lines require ongoing reporting on the receivables and inventory behind them.

Where SBA draws the line

7(a) Small loans, up to $350,000, are term loans only. SBA Express allows revolving lines of credit up to $500,000 with terms of up to ten years. CAPLines, which may be revolving or non-revolving, have a maximum maturity of ten years except for the Builders CAPLine. The 7(a) Working Capital Pilot offers monitored lines of credit up to $5 million with a maximum maturity of 60 months.

504 sits at the other end. It funds buildings, land, and machinery with at least ten years of useful life left, at fixed rates over 10, 20, or 25 years, and it excludes working capital and inventory by rule. The repayment term is matched to the life of the asset, which is the case for a lump sum in one sentence: the thing being paid for is still there when the last payment is made.

What the SBA lines are for

CAPLines exists for short-term and cyclical working capital. The Seasonal CAPLine finances the seasonal build-up of receivables and inventory, and in some cases the extra labor that comes with it. The Contract CAPLine covers the costs of specific contracts, including overhead allocable to them.

The Working Capital Pilot lets a business borrow against receivables and inventory, or draw earlier on a large contract or project. SBA names manufacturing, wholesale, and professional services as typical users. The business needs 12 full months of operations before applying and must produce timely financial statements, receivable and payable agings, and inventory reports, so a business that cannot yet produce those reports is outside the program regardless of how seasonal its need is.

That matches why firms borrow. In the Fed's 2025 Small Business Credit Survey, 56% of applicants were seeking money to meet operating expenses, compared with 46% who wanted to expand, pursue an opportunity, or buy business assets.

What a line costs besides interest

SBA's description of the Working Capital Pilot puts the trade-off plainly. Interest is charged only while the line is in use. The guarantee fee is an annual short-term fee charged for each year the facility is in use, and the lender must collect updated financial statements every year and redo the credit analysis at each renewal. A line that is drawn year-round therefore pays that fee year after year.

The Working CAPLine, an asset-based revolving line, works the same way. Repayment comes as short-term assets turn into cash, the business draws again against what it holds, and because the collateral needs continual servicing and monitoring, the lender may charge additional fees.
