Business credit card or personal card for business spending?
A business card does not put a wall between you and the debt. What it changes is the record, the controls and the rules that apply.

Should I use a business credit card or a personal card for business spending?
Use a business card for business spending, but not because it limits your liability — nearly all of them carry a personal guarantee, so you are on the hook either way. The real differences are cleaner books and a cleaner audit trail, employee cards with spend controls, limits sized to business revenue, and reporting that may build a business credit file. The trade-off is that business cards are largely outside the consumer credit card protections.
The liability question is the one people get wrong, so take it first.
Liability
Almost every small business credit card requires a personal guarantee from an owner. If the business does not pay, the issuer can pursue you personally, whatever the name printed on the card. Corporate cards without a guarantee exist, but they are generally offered to companies with substantial revenue or a deposit relationship, and they are not what most small businesses are shown.
So the honest framing is: a business card does not shield you from the debt. It changes everything around the debt.
Where the real differences are
Where a business card is worse
What each card does to your personal credit file
This is the mechanical difference most people never see, and it runs in the opposite direction from what you would guess.
Business spending on a personal card shows up in your personal utilisation, which is one of the more heavily weighted inputs in consumer scoring. Business spending on a business card usually does not, because most business card issuers do not report the account to consumer bureaus while it is performing.
Move that same $18,000 to a business card at an issuer that does not furnish the account to consumer bureaus and your personal utilisation stays at 10%, even though the debt exists and you are personally guaranteeing it. The exposure did not change. The measurement did.
The asymmetry cuts the other way too. Many issuers that never report your good months will report a serious delinquency, so the account can only hurt the consumer file, never help it. Ask before you apply: does this account report to consumer bureaus, and under what circumstances.
What you are actually signing
Read four things in the cardholder agreement before the rewards table.
If you have been mixing
Common, fixable, and worth fixing before anyone asks for your books.
- Open the business account and move all recurring business charges to it in one pass — subscriptions, fuel, suppliers, software — rather than gradually.
- Reimburse the business or yourself in a single documented transfer for the period you mixed, with a schedule behind it rather than a round number.
- Keep the old statements. You will need them if a lender or an examiner asks how the period was treated.
- Write down the policy, even in one paragraph, so the next twelve months are defensible without reconstruction.
The point of the exercise is not tidiness. A lender reading a personal account full of business activity has to guess at your real revenue and expenses, and underwriters resolve guesses conservatively.
The practical answer
Use a business card for business spending because it produces a clean, defensible record and gives you controls, and treat the liability as personal regardless. If you are choosing between two cards, ask the issuer three questions in writing: does opening this account involve a personal credit pull, what do you report to consumer bureaus and when, and which commercial bureaus do you furnish to. The answers vary more than the rewards do.

Which funding products does this apply to?
Business Credit Cards. Each has its own page listing the funders in this directory that offer it and what each one publishes about its terms.
Are the figures here quotes?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What a particular lender charges is on that lender's page, where it publishes it at all.
Who writes this?
The Find Me Funders research desk. Some drafting is AI-assisted, and every page that is says so at the top, including whether a person has checked its claims yet.
How do I know a figure here is right?
Where a page carries the green notice, its claims were checked against the sources listed at the end and a reviewer is named. Where it carries the amber one, nobody has verified it yet and you should confirm anything you plan to act on.
Are the examples real deals?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What any particular lender charges is on that lender's page, where it publishes it.
Why do you never say what a typical rate is?
Because we cannot source it. A market average assembled from lenders who do not publish prices is a guess with a decimal point on it. Where a lender publishes a figure, we show that figure and say where it came from.
Is this financial or legal advice?
No. It is general information about how these products work. Outcomes depend on your contract and your state, and a lawyer or accountant licensed where you are is the person to ask about your situation.
