A 0% business credit card is not actually free money. It is a business credit card offering a promotional 0% introductory APR for a limited period, commonly around 12 months, although some offers are longer or shorter. During that promotional period, eligible purchases can be financed without interest. After the promotion ends, the remaining balance generally begins accruing interest at the card's regular APR. (NerdWallet)
So, for example:
$50,000 credit limit
0% APR for 12 months
A business could use $30,000 for inventory, equipment, advertising or other business expenses and potentially have 12 months to pay it down without interest—provided the transaction qualifies and the account remains in good standing.
Card stacking means obtaining multiple credit cards to create a larger combined pool of available credit.
For example:
Card #1 — $20,000
Card #2 — $15,000
Card #3 — $25,000
Card #4 — $10,000
Total available credit: $70,000
Some businesses use stacking specifically to obtain several 0% introductory APR cards and create short-term working capital without traditional business-loan financing. (NerdWallet)
Yes, it is legitimate. But it isn't a loophole or guaranteed funding strategy. Multiple applications can create hard inquiries, and approval and credit limits depend heavily on the applicant's credit profile and each issuer's underwriting.
If you obtain a business credit card, you should generally use it for legitimate business expenses and follow the card agreement.
You may personally guarantee the account even though the card is issued to the business. In fact, many business-card issuers rely heavily on the owner's personal credit when making the approval decision. (Small Business Administration)
Using a business card occasionally for a personal purchase may not automatically make the card invalid, but it can create accounting, tax and legal complications, and business credit cards don't necessarily provide the same consumer protections that personal credit cards do. (Consumer Financial Protection Bureau)
There is no standard amount.
It could be a few thousand dollars or substantially more. Your credit profile, income/revenue, existing obligations, relationship with the issuer and the individual card's underwriting all matter.
And here's the important part:
Don't assume that because you qualify for four cards, you'll receive $25,000 on each.
Credit limits are determined individually.
The attraction is obvious:
Use the credit to fund a legitimate business expense today, then pay it back during the 0% promotional period without interest.
That can make 0% cards a useful short-term working-capital tool.
The 0% period eventually ends.
If you put $50,000 on cards and still owe $40,000 when the promotional period expires, that $40,000 can begin accumulating interest at the card's regular APR. Current business-card regular APRs can be well above 20%. (NerdWallet)
And with card stacking, you now have multiple monthly payments and multiple accounts to manage.
The rule I would put in your financing material is:
0% credit is only truly inexpensive if you have a realistic plan to repay it before the promotional period ends.
That makes it a financing tool—not free money.
