In an era where online businesses are growing rapidly, many entrepreneurs are selling products and services through online platforms. These may include general product sales, installment payment sales, or transactions where customers place a deposit before receiving the product. However, one common problem that business owners frequently encounter is customers defaulting on installment payments, failing to pay on time, or refusing to take responsibility, which can cause significant financial losses to the business.
These issues often arise because entrepreneurs do not have a clear contract or rely on generic contract templates downloaded from the internet without legal review by a lawyer. As a result, when disputes arise, the contract being used may not be fully enforceable under the law.
Therefore, drafting a clear and legally sound contract from the beginning is extremely important, especially for online businesses that handle a large number of transactions with customers.
The Importance of Contract Drafting in Online Businesses

Contract drafting is an essential tool for defining the rights and obligations of both sellers and buyers. When terms and conditions are clearly specified, the risk of future disputes can be significantly reduced.
For online businesses, contracts often involve issues such as:
- Product ordering conditions
- Deposit or down payment requirements
- Installment payment terms
- Payment deadlines
- Penalties for late payment or default
- Contract cancellation conditions
When contracts are properly drafted, business owners can use them as strong legal evidence if payment defaults occur or if disputes arise with customers.
Common Problems When Businesses Do Not Have Clear Contracts

Many entrepreneurs start their businesses using only chat messages or verbal agreements with customers. This can lead to several problems, such as:
- Customers stop paying after receiving products through installment plans
- Customers deny agreeing to certain conditions
- Disputes regarding product returns
- Customers refusing to pay the remaining balance
Without a clear contract, business owners may face difficulties when attempting to enforce their legal rights or pursue legal action.
Risks of Using AI-Generated or Internet Contract Templates

Today, many people choose to use AI-generated contracts or online templates because they appear convenient and cost-saving. However, relying on ready-made contracts may carry several risks:
1. Content May Not Comply with Thai Law
Some contract templates are designed based on foreign legal systems. When used in Thailand, certain provisions may not comply with Thai law, making them difficult or impossible to enforce.
2. Contracts May Not Fit Your Business Model
Every business has different risks and transaction structures. Generic templates may not cover the specific needs or risks of your particular business.
3. Lack of Penalties for Payment Defaults
Some contract templates fail to specify penalties or procedures when a party fails to make payments, leaving business owners without adequate protection.
4. No Legal Advice from a Lawyer
Using AI-generated contracts or downloading templates without a lawyer’s review may cause entrepreneurs to overlook critical legal issues.
