Online stores spend in a distinctive way: heavy advertising on social media and search, steady shipping costs, software subscriptions and, for many, large inventory orders. Those are exactly the categories some business cards reward most, which means the right card can be worth far more to an online store than to an average small business.
We tested three typical e-commerce spending patterns in our Business Credit Card Finder, using card terms checked on issuers’ websites on November 4, 2026. Here’s what each card would earn, and why.
The short answer
Table of Contents
- Advertising-heavy stores: the Chase Ink Business Preferred wins, even valued as cash. Its 3X on social media and search advertising and shipping beat a flat 2% card by about $500 a year in our test.
- Shipping-heavy stores: the Ink Business Preferred wins again, by about $265 a year as cash.
- Inventory-heavy stores with big orders: the Chase Ink Business Premier’s 2.5% on purchases of $5,000 or more comes out on top.
- Stores that redeem for travel: the American Express Business Gold, which pays 4X on your top two eligible categories, led our advertising-heavy test with points valued for travel.
Three e-commerce spending patterns
| Store type | Monthly card spending | Mix |
|---|---|---|
| Advertising-heavy | $10,000 | $6,000 ads, $1,500 shipping, $500 software, $2,000 other |
| Shipping-heavy | $8,000 | $1,500 ads, $4,000 shipping, $300 software, $2,200 other |
| Inventory-heavy | $15,600 | $1,500 ads, $800 shipping, $300 software, $8,000 other, plus $5,000 a month in single orders of $5,000 or more |
Results, valued as cash
| Store type | Best card | Yearly value | Flat 2% no-fee card |
|---|---|---|---|
| Advertising-heavy | Chase Ink Business Preferred | $2,905 | $2,400 |
| Shipping-heavy | Chase Ink Business Preferred | $2,185 | $1,920 |
| Inventory-heavy | Chase Ink Business Premier | $3,849 | $3,744 |
Results, valued as travel points (1.25 cents)
| Store type | Best card | Yearly value | Runner-up |
|---|---|---|---|
| Advertising-heavy | American Express Business Gold | $4,050 | Chase Ink Business Preferred ($3,655) |
| Shipping-heavy | Chase Ink Business Preferred | $2,755 | Wells Fargo Signify ($1,920 in cash) |
| Inventory-heavy | Chase Ink Business Premier | $3,849 | Capital One Spark 2% Cash Plus ($3,744) |
How the math works for an advertising-heavy store
The advertising-heavy store spends $90,000 a year on ads and shipping combined, well within the Ink Business Preferred’s $150,000 annual cap for its 3X categories.
- 3X on $90,000 of advertising and shipping = 270,000 points, worth $2,700 as cash
- 1X on the other $30,000 = 30,000 points, worth $300
- Minus the $95 fee = $2,905 a year
A flat 2% card earns $2,400 on the same $120,000. The Ink Business Preferred wins because most of the store’s money goes into its bonus categories.
The best cards for online stores
Chase Ink Business Preferred Credit Card
- 3X points on shipping, social media and search engine advertising, internet, cable and phone, and travel, on the first $150,000 a year combined; 1X on everything else
- $95 annual fee, no foreign transaction fees
- Points transfer to airline and hotel partners or redeem for cash at 1 cent each
Best for: stores spending a large share on ads and shipping. If your combined ad and shipping spending exceeds $150,000 a year, the extra earns 1X, so consider pairing it with a flat 2% card for spending beyond the cap.
Chase Ink Business Premier Credit Card
- 2.5% on each purchase of $5,000 or more; 2% on everything else
- $195 annual fee (as reported; confirm with Chase); designed to be paid in full
Best for: stores placing large inventory orders by card. It beats a 2% no-fee card once you spend more than $39,000 a year in purchases of $5,000 or more.
Wells Fargo Signify Business Cash Card
- 2% on everything, no categories or caps; $0 annual fee; 0% intro APR for 12 months on purchases
Best for: stores whose spending isn’t concentrated in ads or shipping, or as a second card for spending beyond another card’s cap.
American Express Business Gold Card
- 4X points on the two of six eligible categories where you spend the most each billing cycle (first $150,000 a year combined); 1X elsewhere
- $375 annual fee (as reported); American Express has announced that two eligible categories will narrow on February 17, 2027
Best for: stores that redeem points for travel. As statement credits, Amex points are worth much less, and the card loses its edge.
Capital One Spark 2% Cash Plus
- 2% on everything; $150 fee refunded each year you spend $150,000; designed to be paid in full
Best for: larger stores spending well over $150,000 a year that want a card without a preset spending limit for big inventory orders.
A two-card setup for online stores
Pairing the Ink Business Preferred for advertising and shipping with a flat 2% card for everything else captures the best of both. For our advertising-heavy store:
- Ink Business Preferred on ads and shipping: $90,000 × 3% = $2,700
- 2% card on the other $30,000: $600
- Minus the $95 fee: $3,205 a year
That’s about $300 more than using the Ink Business Preferred alone ($2,905) and about $800 more than a 2% card alone ($2,400). The setup takes a few minutes: put your ad accounts and shipping software on the Ink card and everything else on the 2% card.
Which card by store size
| Annual card spending | Typical store | What usually fits |
|---|---|---|
| Under $50,000 | Side business or new store | A no-fee 2% card; Amex Blue Business Cash also pays 2% at this level |
| $50,000 to $150,000 | Growing store | Ink Business Preferred if ads and shipping dominate; otherwise an uncapped 2% card |
| $150,000 to $500,000 | Established store | Ink Business Preferred for ads and shipping up to its cap, plus a 2% or large-purchase card for the rest |
| Over $500,000 | Large store | Compare pay-in-full cards with high spending power, and ask issuers about business programs |
Selling on marketplaces
If you sell on marketplaces, your costs are often deducted from payouts rather than charged to a card, so they don’t earn rewards. Costs you pay directly, such as ads on other platforms, shipping labels you buy yourself, software and inventory, can go on a card. Check how each platform bills you before planning around rewards.
Bookkeeping and sales tax
A dedicated card makes e-commerce bookkeeping much easier: connect it to your accounting software, tag ad spending by channel and separate inventory purchases from operating costs. That makes it simpler to calculate cost of goods sold and margins, and to support deductions at tax time. Sales tax you collect from customers isn’t a card matter, but keep your sales records separate from your card records so each reconciles cleanly.
Watch the caps
- Ink Business Preferred: 3X stops at $150,000 a year in combined bonus categories.
- Amex Business Gold: 4X stops at $150,000 a year combined.
- Amex Blue Business Cash: 2% stops at $50,000 a year in total spending, which many stores pass quickly.
A store spending $25,000 a month on ads would reach the Ink Business Preferred’s cap in six months. After that, a flat 2% card would earn more on new ad spending. Many growing stores use two cards for this reason.
Paying overseas suppliers
If you buy inventory from suppliers abroad, foreign transaction fees can cost about 3% of those purchases on many cards. On $5,000 a month of overseas orders, that’s about $1,800 a year, which can wipe out your rewards. The Ink Business Preferred doesn’t charge foreign transaction fees; check each card’s terms. Also compare card payments with wire transfers or payment services your suppliers accept, which may cost less.
Inventory and cash flow
Online stores often pay for inventory weeks before they sell it. A card can help bridge that gap:
- Statement timing: buying just after your statement closes gives you roughly a month or more before payment is due, interest-free if you pay in full.
- 0% intro APR: a card with 0% for 12 months on purchases can spread the cost of a big seasonal order, if you’ll sell it within the intro period. See business credit cards with 0% intro APR.
- Spending power: large orders can bump into credit limits. Pay-in-full cards such as the Spark 2% Cash Plus are designed for high monthly spending; see business charge card vs credit card.
Don’t let a card become long-term inventory financing at 20% or more. If stock sells slowly, interest will eat your margin.
Preparing for peak season
Many online stores do a large share of their sales in a few months, such as the holiday season. Peak season pushes card spending up sharply: more inventory, more ads and more shipping. Plan for it:
- Ask for a credit limit review a couple of months before peak season, after a run of on-time payments.
- Time inventory orders so payment is due after peak sales start coming in.
- Watch your bonus caps. A store that spends heavily on ads in the fall can hit a $150,000 annual cap early; switch new spending to a 2% card once you do.
- Keep a cash reserve for slower months after the peak, when big card bills from the season come due.
- Review results in January. Rerun the finder with your real yearly numbers to see whether your cards still fit.
Advertising platforms and card rewards
Ad platforms bill your card frequently, sometimes several times a month. That makes advertising one of the easiest categories to earn rewards on. To make sure purchases count as advertising for bonus purposes, buy directly from the ad platform rather than through a reseller or agency, since how a purchase is categorized depends on how the merchant processes it. Check your statements in the first month to confirm.
Employee and contractor spending
Stores with staff or virtual assistants buying supplies or running ad accounts can give them employee cards with limits. Employee purchases earn rewards on your account and count toward caps.
Mistakes online stores make
- Using a capped card when spending is well over $50,000 a year.
- Paying foreign transaction fees on overseas inventory.
- Carrying inventory balances at high interest.
- Choosing a points card but redeeming for cash.
- Buying ads through a reseller whose purchases don’t earn the advertising bonus.
Frequently asked questions
What’s the best credit card for an online store?
If advertising and shipping dominate your spending, the Chase Ink Business Preferred often earns the most. For large inventory orders, consider the Ink Business Premier. Otherwise, a flat 2% card.
Do ad purchases earn bonus rewards?
On cards with an advertising category, purchases directly from social media and search engine platforms usually qualify. Check the card’s terms.
Can I put inventory orders on a business card?
Yes, if your supplier accepts cards. Watch for supplier surcharges and foreign transaction fees.
How do I handle the $150,000 cap?
Add a flat 2% card for spending beyond it.
Are points or cash back better for an online store?
Points can be worth more if you’ll redeem for travel; otherwise choose cash back.
Do shipping labels count as shipping purchases?
Usually, when bought directly from a carrier or a shipping service categorized as shipping. Check your first statements to confirm.
Should I use a business card for my store if I’m just starting?
Yes. A no-fee card keeps store spending separate from personal spending from day one.
Do marketplace selling fees earn rewards?
Usually not, because marketplaces deduct their fees from your payouts rather than charging your card. Ads and shipping labels you buy yourself can earn rewards.
