Business credit cards win for sub-$50K rotating purchases and travel/T&E. Lines of credit win for $50K+ working capital, inventory, and AR float. APR, limit, approval bar, and stacking economics — with a side-by-side reference across card, LOC, SBA 7(a) working capital, and MCA.
Yes — and rewards are often a primary reason to use a business card for ordinary purchases. Cash-back and points programs work mechanically the same as on consumer cards. Category bonuses are typically tuned to business spend (advertising, office supplies, telecom, shipping). The catch: rewards are economically valuable only if you pay the balance in full. Carrying a balance at 22–28% APR to earn 1.5–5% rewards is a losing trade.
Both almost always require a personal guarantee from the primary owner. Differences in practice: business cards typically use a standard payment guarantee tied to the cardholder agreement; bank lines of credit use a separately negotiated guaranty agreement that may be capped, time-limited, or pro-rata in multi-owner deals. A few EIN-only business cards (Brex, certain commercial cards for VC-funded startups) avoid the personal guarantee — they're the exception, not the rule.
Practice varies by issuer. AmEx, Chase, Capital One business cards generally do NOT report ordinary activity to consumer bureaus — only delinquencies. Some issuers (Discover, Capital One on certain products) report business card activity to consumer bureaus, which can affect personal utilization-driven scores. The personal guarantee creates a contingent obligation but doesn't itself report as a tradeline. If maintaining personal credit utilization is important, ask the issuer about reporting practice before applying.
When the LOC rate beats the card rate AND you can actually qualify for the LOC. The breakeven is usually clear: if you're paying 24% on a card balance and a bank LOC quotes Prime + 4 (currently ~10–11%), every $10K of balance moved saves ~$1,300/yr in interest. The blocker is qualification: bank LOCs typically require 680+ FICO, 2+ years time-in-business, $200K+ annual revenue, and clean bank statements. If you can't qualify for a bank LOC, an SBA 7(a) working capital line, an asset-based line secured by AR/inventory, or a fintech LOC can fill the gap — each with its own pricing premium.
Pricing and approval. Bank LOCs (Wells, Chase, regional banks) are typically the cheapest — Prime + 2 to Prime + 6, monthly maintenance fees, and a tight approval bar (2+ years TIB, strong revenue, established banking relationship). Fintech LOCs (the bank-partner-fronted ones) are easier to approve — often 1 year TIB and $100K+ revenue — but priced higher: 12–25% APR equivalent, sometimes with a per-draw fee. Use the bank LOC if you qualify; use the fintech LOC as a step-up product when you don't.
Yes, and the combination is often optimal. The card handles small rotating purchases (travel, software, supplies) and earns rewards. The LOC sits as standby capacity for working-capital draws (inventory, payroll bridge, AR float) at materially lower cost. Use the card for everyday spend you'll pay in full monthly; tap the LOC for larger amounts you'll repay over 30–90 days. The total available credit is bigger and the average cost of capital is lower than relying on either alone.
Some bank LOCs charge a fee on the undrawn portion of the line — typically 0.25%–0.50% per year. The mechanic: if you have a $250K line and average $100K drawn, the unused commitment fee on $150K at 0.50% is $750/yr. It's a cost of having the line available even when you don't draw. SBA Express lines of credit and some bank lines waive the unused commitment fee for the first $X of unused capacity. Ask before you sign.
When you need a larger line ($500K–$5M), a longer commitment (the SBA 7(a) CAPLines program offers up to 10 years), or you don't qualify for a conventional bank LOC at the size you need. SBA pricing is competitive (Prime + a regulated spread cap) but the approval timeline is longer (4–8 weeks) and documentation is heavier. For smaller, faster needs, a bank LOC is usually preferable. For larger or longer commitments, SBA 7(a) often wins on all-in cost.
No. An MCA (merchant cash advance) is a lump-sum purchase of future receivables, not a revolving credit facility. There's no rotating availability — you receive a lump sum and repay via fixed daily/weekly debits over 4–18 months. MCAs are typically the most expensive working-capital product (factor rates of 1.20–1.50 translate to effective APRs of 40–150%+). They have a place — fast capital with no FICO floor — but they're not equivalent to a card or LOC and shouldn't be compared on rate alone. See our SBA-vs-MCA real cost page for the full breakdown.
Annual fees ($95–$695+ on premium business cards), foreign-transaction fees (1–3% on cards without travel benefits), balance-transfer fees (3–5% one-time), cash-advance fees (3–5% + a separate higher APR with no grace period), and late-payment fees ($29–$40+ per missed payment). Rewards economics only beat fees if you spend in bonus categories and pay in full. Premium-fee cards make sense only when the bonus categories match your spend mix.
