Pros

• Uncapped 2% cash back on all net purchases
• NPSL capacity plus free employee and virtual cards
• $150 annual fee refunded at $150,000 net spend by anniversary
• Large year-1 bonuses — $2,000 at $30k/3 mo plus $2,000 per $500k spent
• $0 foreign transaction fee; 5% on Capital One Business Travel hotels/VR/cars

Cons

• $150 fee is real if spend stays below $150k/year
• Pay-in-full design — 2.99% late fee and Pay Over Time interest if you carry
• Bonus hurdles favor very high spenders ($30k/3 mo, $500k increments)
• No 0% intro APR and no balance transfers
• Bonus often blocked for existing/previous Capital One Business cardholders

Ink Business Cash® Credit Card

Cons

• 3% foreign-transaction fee
• Base rate 1% loses to flat 1.5–2% cards outside the bonus buckets

Verdict

Spark Cash Plus

Capital One Spark Cash Plus is the go-to for businesses with serious spend who can pay in full. Uncapped 2%, NPSL flexibility, free employee/virtual cards, and a refundable $150 fee at $150k make it a premium flat-rate engine — especially with the live $2,000 welcome bonus and limited $500 travel credit (through Sep 7, 2026). Poor fit for 0% financing seekers, lounge hunters, or businesses under $150k annual card spend.

Ink Business Cash® Credit Card

Ink Cash is the category SKU in the $0-AF Ink pair — not Unlimited (flat 1.5%) and not Preferred ($95, 3x ads/shipping/travel, $0 FTF, native transfers). It wins when office supplies and phone/internet/cable bills (plus some gas and dining) sit under two separate $25k anniversary caps. Pair it with Unlimited or Preferred rather than using it as an uncapped daily driver. Skip it for foreign spend, ad-heavy businesses, no-PG underwriting, or if a prior Ink Unlimited/Cash card already burned the $0-AF bonus.
