What are the best working capital solutions for cleaning contractors — lines of credit, MCAs and cash flow tools?

For most commercial cleaning and janitorial contractors, the best all-round working capital tool is a business line of credit: revolving cash you draw only when you need it, with interest charged only on the balance you use. Lines of credit run roughly 10% to 60%+ APR depending on lender and credit, far below the cost of a merchant cash advance, which can reach 40% to 350%+ effective APR (NerdWallet, updated 01/06/2026). Reach for an MCA only when nothing cheaper will fund in time.

Working capital covers the gap between paying your crew, supplies and chemicals now and getting paid on net-30/60/90 commercial contracts later. The right tool depends on how predictable that gap is and how fast you need the cash.

The main working capital tools, compared

• Business line of credit — the workhorse. Draw, repay, redraw up to a set limit; pay interest only on what's outstanding. Best for recurring or unpredictable gaps: a late-paying building manager, an emergency buffer repair, a payroll run before a contract clears. See our business lines of credit guide for how draws and limits work.
• Short-term working capital loan — a lump sum repaid over 3–18 months. Predictable, good for a one-off cost, but you pay interest on the whole amount from day one.
• Invoice factoring — you sell unpaid commercial invoices to a factor for an advance (often 80–90% upfront), useful when slow-paying contracts are the whole problem.
• SBA working capital line — the cheapest option if you qualify. The SBA's 7(a) Working Capital Pilot offers monitored revolving lines up to $5,000,000, charging interest only when the line is used, but it requires at least 12 months of operating history and full financials (U.S. SBA). The older CAPLines program similarly funds cyclical and contract-based working capital (SBA 7(a) overview, sba7a.loans).
• Merchant cash advance (MCA) — fastest, loosest qualification, and by far the most expensive. Covered below.

The honest MCA cost warning

An MCA is not a loan — it's a sale of your future revenue, priced with a factor rate (typically 1.10–1.50), not an interest rate. A factor rate of 1.30 on $50,000 means you repay $65,000 (getoutofdebt.org). With most MCAs your cost is locked in at funding, so paying off quickly does not save you money and pushes the effective APR higher — though some lenders do offer prepayment discounts, so always ask whether early payoff reduces the total (Merchant Maverick). Effective rates commonly run into triple digits, reaching 70%–350%+ once broker commissions and origination fees buried in the factor rate are counted (getoutofdebt.org). MCAs have drawn heavy regulatory scrutiny: a 1.10–1.50 factor can disguise predatory pricing, and states are now adding disclosure rules (biz2credit). For a cleaning contractor, an MCA makes sense only as a short bridge you can clearly repay from a known incoming contract payment — never as ongoing operating cash.

How to choose

Start with the cheapest tool you can qualify for and work down only if speed forces you to: SBA line → conventional line of credit → short-term loan or factoring → MCA as a last resort. Match the term to the need — a line of credit for recurring gaps, a fixed loan for a one-time cost. If slow contract payments are the root cause, see cash flow management for cleaning businesses before taking on any high-cost financing.
