Line of credit or business credit card?
They both sit ready until you need them, but they’re built for different kinds of spend. Here’s the honest comparison, including the parts where a card is simply the better tool.
Side by side.
Lumen line
Business credit card
Typical limit
$10,000–$250,000, sized to revenue and cash flow
Usually $5,000–$50,000, sized more to personal/business credit history
Cash access
Draws land as real cash in your bank account, at the line's own rate
Cash advances are technically possible but expensive — a separate, higher APR plus an upfront fee, often 3–5% of the advance
Interest shape
Daily simple interest on the drawn balance only — the undrawn portion costs nothing
Interest on carried balances, often at a higher APR than a line, and it compounds if you're not paying in full
Fees
No monthly maintenance fee, no dormancy fee, no prepayment penalty
Annual fees are common on rewards cards, plus foreign transaction and cash-advance fees on top of the base APR
Rewards
None — a line is priced purely on cost of capital, not spend-back perks
This is where cards win outright — cash back, points, or travel rewards on everyday purchases a line simply doesn't offer
On rewards and small, everyday spend, a card genuinely wins — that’s not a hedge, it’s the honest read. A line earns its place on the rows above it.
Which one fits the spend in front of you.
Reach for the line
Line when…
- You need real cash — payroll, a supplier invoice, a contractor payment — not a card swipe.
- The amount is large enough that a card's lower limit or advance fee would eat the value.
- You're bridging a defined gap and want interest to stop the day you repay, not carry forward.
- The spend isn't the kind a merchant accepts a business card for in the first place.
Reach for the card
Card when…
- The purchase is everyday, card-payable spend — software subscriptions, travel, office supplies.
- You plan to pay the statement in full and want the rewards or cash back for doing exactly that.
- You want a small, simple revolving limit without an underwriting process sized to your revenue.
- The purchase protections, expense tracking, or card-specific perks are worth more than the float.
