How we picked
Filtered to lenders that fund the security guard and contract-services vertical at the loan structures the cash-flow profile actually needs. AR factoring specialists ranked first because the structural cash-flow gap in security guard services is net-30 to net-90 invoice timing, and factoring is the structurally correct financing tool. LOC-first alternative lenders prioritized because revolving capital matches payroll cycles better than fixed-daily MCA. SBA 7(a) included for established firms doing acquisitions or large contract-driven expansions. Multi-product working capital included for established multi-contract operators. Short-tenor working capital reserved strictly for true 30-60 day payroll bridges on a confirmed contract award.

Detailed reviews — our 6 picks
#1 · Best AR factoring for security guard contract receivables
altLINE (Southern Bank)
Max amount
$4,000,000 per month
Cost
0.5 – 3% per invoice (lower than non-bank competitors)
Speed
1 – 3 business days from setup
Min credit
Any
Why we picked it
altLINE (a division of The Southern Bank) is one of the few bank-owned AR factoring sources and the cleanest financing structure for security guard services. Advances 80-90% of invoice value within 24 hours of invoicing, releases the balance (less factoring fee) when the customer pays. Effective APR-equivalent 12-25% depending on payor mix and term, which is dramatically cheaper than daily-ACH MCA against the same cash flow. The right tool for the structural net-30 to net-90 payroll-gap problem.
The strength
Bank-direct factoring (Southern Bank subsidiary) — often lower rates than non-bank competitors due to bank funding costs. No long-term contract required. Good fit for B2B businesses with creditworthy customers.
The watch-out
Slower setup than non-bank competitors (longer due diligence). Smaller market presence than altLINE's parent bank suggests.
Qualifications
6 months
$30,000+ in AR
Any
#2 · Best AR factoring for government-contract and commercial-property security
Triumph Business Capital
Max amount
Per-invoice; tailored to fleet
Cost
1 – 3% per invoice
Speed
Same-day funding
Min credit
Any
Why we picked it
Triumph is one of the largest factoring providers in the commercial-services space and underwrites government-contract security firms (federal-contract holders, state and municipal contract holders) and commercial-property security firms regularly. They are comfortable with the longer net-60 to net-90 government payment cycles and the documentation requirements of federal payors. Cleanest AR factoring source when a meaningful share of the book is government contract revenue.
The strength
Affiliated with Triumph Bancorp (publicly traded) — financial stability stronger than many trucking-specialty competitors. Strong tech platform. Free shipper credit checks.
The watch-out
Higher minimums than Apex or smaller competitors. Bank-style underwriting can be slower for first-time customers.
Qualifications
6 months
$25,000+
Any
#3 · Best line of credit for established firms with commercial-grade payor mix
Bluevine
Max amount
$250K
Cost
APR 6.2% – 27%
Speed
1 – 3 business days
Min credit
625+
Why we picked it
BlueVine offers an AR-aware line of credit (up to $250K) for service businesses with 6+ months TIB and $40K+/mo revenue. Revolving structure means you draw to cover payroll, the LOC repays when the AR clears, and you draw again the next cycle — which is the structurally correct shape for security guard payroll. APR-equivalent 6-13%, faster underwriting than factoring (often 24-48 hours), no per-invoice administration. Right fit for firms that have outgrown factoring administration but aren't yet at SBA-LOC scale.
The strength
Materially cheaper than any MCA when you qualify. Strong product-led UX. Builds business credit (reports to commercial bureaus).
The watch-out
Higher qualification bar — 12+ months TIB, 625+ credit, established revenue. Not an option for thin-file or B/C-paper merchants.
Qualifications
12 months
$10,000
625+
#4 · Best fast term loan or LOC for contract-award ramp-up
OnDeck
Max amount
$400K (term); $6K
Cost
Term APR 27%+
Speed
Same-day for approved files
Min credit
600+
Why we picked it
When a security guard firm wins a new contract that requires immediate payroll ramp before the first invoice clears, OnDeck's term loan and LOC products (24-hour funding for clean files, 625+ credit, $100K+ annual revenue, 1+ year TIB) are the standard fast-capital source. Fixed-payment structure on the term loan and revolving structure on the LOC are both more appropriate than MCA against this cash-flow profile. Use the LOC product for repeat contract-ramp use, the term loan for a single defined contract-award capital need.
The strength
Direct-lender brand trust. Same-day funding on approved files. Term loan product fills the gap between SBA and MCA.
The watch-out
Their broker/ISO program has a high entry bar (2+ years, $1M+/mo volume). Most merchants access OnDeck directly, not via brokers.
Qualifications
12 months
$8,000
600+
#5 · Best multi-product working capital for established multi-contract operators
Strategic Funding Source (Kapitus)
Max amount
$750,000+
Cost
Factor 1.18 – 1.45
Speed
1 – 3 business days
Min credit
575+
Why we picked it
Kapitus reads security guard P&L better than most generalist MCA funders — they will look at signed contract pipeline and AR aging as leading indicators rather than punishing trailing-90-day bank statements during a contract ramp. Multi-product (MCA, LOC, term loan, equipment) means the right structure can be matched to use of funds. Useful for 5+ contract operators that need flex across the book rather than financing against a single payor's payment cycle.
The strength
Operating as Kapitus since rebrand. Multi-product alt-fin: MCA, term loans, equipment financing, invoice factoring, SBA helper, payroll. Strong industry breadth.
The watch-out
Cross-sell pressure on bundled products. Pricing not always the most competitive on any single product.
Qualifications
6 months
$15,000
575+
#6 · Best SBA 7(a) for security guard firm acquisitions and large expansions
Live Oak Bank
Max amount
$25,000,000+
Cost
SBA 7(a) APR prime + 2.75% to 4.75%
Speed
30 – 90 days underwriting (SBA standard)
Min credit
680+ typical
Why we picked it
Live Oak underwrites contract-services acquisitions including security guard firms regularly. Right structure for an established operator buying a competitor's contract book ($1.5M-$5M acquisition price), expanding into a new geographic market that requires a regional office and licensure investment, or restructuring an over-leveraged MCA stack into a clean SBA 7(a) at Prime + 2.75-4.75% APR. 90-120 day timeline so not appropriate for fast bridge needs but decisive for strategic capital.
The strength
Largest SBA 7(a) lender in the US by dollar volume for 7+ consecutive years. Industry-specialty teams (veterinary, dental, funeral homes, self-storage, agriculture, hotels). Deep understanding of niche-vertical underwriting. Dramatically cheaper than MCA for qualifying merchants.
The watch-out
Long underwriting timeline (45-90 days typical). Requires strong credit (680+), 2+ years operating, clean financials. Industries outside their specialty get less attention.
Qualifications
24 months
$20,000+
680+ typical
Frequently asked questions
- Why is AR factoring better than MCA for security guard businesses?
- The structural cash-flow gap in security guard services is timing — guards are paid weekly or bi-weekly but customers (especially government, commercial-property, and HOA payors) pay on net-30 to net-90 terms. AR factoring directly addresses the timing gap: you invoice, the factor advances 80-90% within 24 hours, and the balance releases (less fee) when the customer pays. MCA addresses the symptom (cash shortage) with a structurally wrong tool (daily ACH against revenue that lands on a 30-90 day cycle), which forces stacking when the next invoice cycle stretches. Effective cost of factoring (12-25% APR-equivalent) is dramatically cheaper than MCA equivalents (40-100%+) against the same cash flow.
- How fast can I get factoring approved for a new security contract?
- Most factoring providers (altLINE, Triumph) can approve a security guard firm and fund the first invoice advance within 5-10 business days of receiving complete onboarding documentation (articles, license, insurance, contract copies, customer credit information). Subsequent invoices fund within 24 hours of submission. The slow piece is the initial customer-credit verification on each new payor, which is why factoring works better for firms with stable repeat-customer books than for firms doing one-off short-term jobs.
- Can I get MCA for a security guard business?
- Yes, and most generalist MCA funders will fund the vertical, but it is structurally the wrong tool for the recurring net-30 to net-90 AR gap. The narrow case where short-tenor MCA fits is a true 30-60 day payroll bridge on a confirmed contract award before factoring or LOC funding closes, or a single-event payroll bridge during a contract transition. Sustained MCA use against security guard cash flow compounds badly — daily ACH against revenue that lands monthly forces stacking. For sustained working capital, AR factoring (altLINE, Triumph) or an AR-aware LOC (BlueVine, OnDeck) is the structurally correct tool.
- How much working capital do I need to win a new $1M security contract?
- Rough rule of thumb: $80K-$250K of float for the first 30-90 days, depending on payor terms and contract ramp speed. A $1M annual contract is roughly $80K/month in revenue; if the payor is on net-60 you need to float 2 months of payroll (roughly 60-70% of revenue, so $100K-$120K) before the first invoice clears. Government contracts on net-90 push that to $200K-$250K. AR factoring solves this without taking on debt — the factor advances 80-90% of each invoice as it is generated, so you self-fund the ramp out of working capital that scales with the contract.
