Read Before You Sign: What a Simple Business Card Application Taught Me

I needed a company card. Nothing complicated. A card to handle online subscriptions, overseas purchases, routine operational spending. The kind of thing every small business needs to function in 2026.

The bank put a document in front of me. Twenty-three pages in Thai.

I did not sign it.

Here is why that matters, and why you should think carefully before you do the same.

What I Actually Asked For

My company, LAN Business Consulting Co., Ltd., needed a payment card to use for purchasing online tools, software subscriptions, international supplier payments. I was willing to deposit the full amount as security. Simple, low-risk, straightforward.

What the bank proposed was not a credit card.

It was an overdraft facility with a business collateral agreement, a personal guarantee contract, a broad data sharing consent, and a power of attorney. Twenty-three pages for what most people would call a basic business card.

Someone who does not read Thai, does not understand contract structure, or simply trusts that the bank would not put anything unreasonable in front of them might have signed it on the spot.

What Was Actually in Those Documents

Let me be specific, because these details really matter.

The personal guarantee had a no cost ceiling. The credit limit was 20,000 THB. Modest. But the guarantee did not cap my liability at 20,000 THB. It covered the principal, plus all interest, plus all fees, plus all enforcement and legal costs. Open-ended. No expiry. Surviving company restructure, change of directors, or dissolution. If the company defaulted for any reason, the bank could come directly to me without first pursuing the company.

That is not a guarantee for 20,000 THB. That is an unlimited personal liability instrument dressed as one.

The data consent was broad. Buried in the direct debit authorisation was consent to share my personal and company data with third-party business partners, co-brand partners, cloud computing providers, and overseas entities. For marketing purposes. That consent had nothing to do with operating a payment card. It was attached because I was signing documents and it was efficient for the bank to collect it at the same time.

The product was wrong. An overdraft on a current account is not a credit card. The fee structure is different. The accounting treatment is different. The usage mechanics are different. I had asked for a card. I was being offered something else.

None of this was hidden. It was all there in the documents. The assumption is that most people will not read it carefully, or will not understand what they are reading if they do.

Why Small Business Owners Sign Without Reading

I get why it happens, you are busy, no time to read the small print. The bank officer is helpful and professional. The credit limit is small so the risk feels small. You trust the institution. You assume that standard bank documents are standard, meaning fair and balanced.

None of those assumptions are wrong exactly, but none of them protect you either.

Standard bank documents are standard for the bank. They are written to protect the bank’s position comprehensively. That is not a criticism. It is simply what they are. Your job, before you sign, is to understand what you are agreeing to and whether it is appropriate for your situation.

Most people have not been trained to read contracts. And are operating in a second or third language. Many are in markets where the legal framework is unfamiliar. In Thailand, for example, the personal guarantee structure I described is common and legally enforceable. It is not unusual for a bank to propose it. What is unusual is a borrower who reads it carefully enough to push back.

What You Should Check Before Signing Any Business Facility

These are not complicated checks. They take time but not expertise.

1. Is this the right product? Ask the bank to confirm in plain language what you are signing up for. A credit card, an overdraft, a loan, a prepaid facility. They are different products with different implications. If you asked for one and are being offered another, ask why.
2. What is the full extent of your personal liability? If you are signing a personal guarantee, read it. What is the maximum amount you can be held liable for? Does it include costs and interest beyond the principal? Does it expire? Does it survive changes to the company structure? These are yes or no questions. Get clear answers.
3. What happens if you default? Can the bank come directly to you or must it pursue the company first? Can it freeze and liquidate your accounts without advance notice? What are the notification timelines? Know the sequence before you are in it.
4. What data consents are you signing? Separate the operational consents, the ones needed to run the facility, from the marketing and data sharing consents. You may have the right to decline the latter. Ask.
5. Is the collateral structure proportionate? If you are depositing cash as security, the facility should be structured around that deposit. A cash-secured facility should not carry open-ended personal liability on top of the deposit. If it does, ask for it to be restructured or find a different product.

What I Did 

I did not sign. I went back to the bank and asked specifically for a corporate credit card, a separate product with a cleaner structure for my use case. For businesses primarily paying online subscriptions and making overseas purchases, a prepaid corporate card is also worth considering. It carries no guarantee structure, it is straightforward to manage in your accounts, and the risk is capped at the balance you load.

The right product exists. It just was not the first one put in front of me.

I have built businesses in Thailand. I understand how Thai regulatory and banking structures work. I read contracts and agreements carefully, before I sign.

Most small business owners are not in that position. And the gap between what they understand and what they are agreeing to is where problems are made.

This is not about distrust. Good banks, professional officers, standard documents. None of that changes the fact that your signature is your liability, and liability does not come with a disclaimer that says you did not read the clause.

Read the document. Ask the questions. Get the right product. If you cannot read the language it is written in, get it translated before you sign, not after.

Twenty-three pages took me less than an hour to work through. That hour protected my company from an open-ended personal liability I had not asked for and did not need.

An hour is a reasonable investment.
