Card stacking means opening several business credit cards in a short window to assemble a large pool of 0% intro credit. Here is how it works, what happens after the intro period, and how consultants charge for it.
✓ Checking what you qualify for does not affect your credit score.
Short answer: card stacking can give a business interest-free credit for the length of each card’s intro APR period. The costs show up elsewhere: several hard inquiries on the owner’s personal credit, the card’s regular APR on any balance left when the intro period ends, and, if you hire a consultant, a fee that can be a percentage of the credit obtained.
Published . This is a neutral explainer; Merchant Fund Express does not offer card stacking.
A consultant or the owner applies for several business credit cards from different issuers, usually close together so that each application is decided before the next issuer sees the new accounts. Each approved card carries its own limit and its own introductory APR, often 0% for a set number of months. Added together, the limits form the stack.
The cards are credit lines for purchases. Using them for expenses a card can pay directly, such as inventory from a vendor that accepts cards, keeps the intro rate. Turning card credit into cash in the bank account is different: cash advances on a card usually carry their own fee and a higher APR, and any third-party method for converting limits to cash has its own costs. Read each card agreement before counting on cash.
Each card application is normally a hard inquiry on the owner’s personal credit report, and business cards commonly look at the owner’s personal credit. Several applications in a short period means several inquiries and several new accounts, which can lower a score and make the next application harder. High balances on the new cards also raise reported utilization if the issuer reports business card balances to the personal bureaus.
That matters if you also plan to apply for a loan or line in the coming months. If your score is near a cutoff, read credit score requirements first.
When an intro period ends, any remaining balance on that card starts accruing interest at the card’s regular APR, which is set in the card agreement and is usually variable. Each card in the stack can end its intro period on a different date. The plan that makes stacking work is a payoff plan: know which balance comes due at which rate in which month, and have cash flow to clear it or a cheaper way to carry it.
| Stage | What you pay | Main risk |
|---|---|---|
| Application window | Any consultant enrollment fee | Several hard inquiries at once |
| Intro period | Minimum payments; 0% APR on qualifying balances | Cash-access fees if you convert limits to cash |
| Intro ends | Regular APR on the remaining balance | A large balance repricing on one date |
| Ongoing | Card fees per each agreement | Higher utilization weighing on personal credit |
Owners can apply for cards themselves. Consultants sell help with the sequence, the applications and sometimes credit repair. The fee models you will see fall into two groups:
| Credit obtained | Fee at 8% | Fee at 10% |
|---|---|---|
| $50,000 | $4,000.00 | $5,000.00 |
| $100,000 | $8,000.00 | $10,000.00 |
| $250,000 | $20,000.00 | $25,000.00 |
A percentage fee is owed on the credit obtained, whether or not you use all of it. On a 0% stack, that fee is the main cost of the money during the intro period, so compare it with what the same amount would cost on a line or a short term loan.
Merchant Fund Express publishes its business term loan at $10K–$250K, with the loan amount capped at 15% of annual revenue and terms of 12 to 18 months, and its business line of credit at $10K to $350K, from 1% per month with a 2.49% fee per draw. A line charges only on what you draw, and an unused line costs nothing to keep open. If you need money for longer than an intro period, or need it as cash in the account rather than card purchases, a line can cost less than a stack once fees and post-intro APRs are counted. The worked 12- and 24-month comparison is on credit card stacking vs a business line of credit, and the product-level differences are on business line of credit vs business credit card.
Opening several business credit cards in a short window to combine their limits, usually to use 0% intro APR periods.
Each application is normally a hard inquiry, and new accounts and high balances can weigh on a score. Several at once can make the next application harder.
Any remaining balance on that card starts accruing interest at the regular APR in the card agreement. Each card can end its intro period on a different date.
Models vary. Liberty Funding, for example, publishes a performance plan of 8 to 10% after funding is received, plus a flat-fee plan.
No. Merchant Fund Express publishes a business line of credit from $10K to $350K and a term loan from $10K to $250K.
Same-day decision. Applying takes a few minutes and will not affect your credit score.
