What is Credit Card Installment?
Credit Card Installment is when a merchant accepts payment for goods or services and chooses to receive payments in periods or monthly installments instead of an immediate full payment from the customer. This allows customers to avoid using a large lump sum at once, while the merchant receives money from the installment payments via a Payment Gateway according to the conditions agreed upon with the service provider.
- 0% Interest Type: When the merchant joins a promotion to absorb the transaction fee (MDR) on behalf of the customer. This is considered a highly effective strategy to create purchasing incentives.
- With Interest Type: Subject to the conditions of each card.
To ensure merchants receive the maximum return from promotions and manage costs efficiently, they should check promotion and installment conditions, as well as calculate the Merchant Discount Rate (MDR) thoroughly before presenting offers to customers.
*Use as necessary and pay back in full on time to avoid interest of 9% - 16% per year.
Pros and Cons of Credit Card Installments
Accepting credit card installments is a financial option that has both pros and cons for business operations. Understanding both sides will help merchants plan their marketing and finances carefully.
Pros of Credit Card Installments
Credit card installments help increase customer purchasing power, allowing your business to break down price barriers for high-priced items more easily. This directly affects the stimulation of purchasing decisions and helps merchants close sales on high-margin products more effectively.
Cons and Precautions
Despite the advantages, merchants must be aware of long-term burdens, such as bearing the Merchant Discount Rate (MDR) for 0% installment transactions or managing account reconciliation if the Payment Gateway system does not have comprehensive management tools.
How to Start Offering Product Installments

Accepting payments via credit card installments is just the beginning, but generating sales requires precise planning and strategy.
Survey the Market and Competitors
Offering installment promotions requires comparison with competitors to make your offer attractive and competitive. Check competitors' 0% promotions and find the right time to launch your campaign, such as during annual sale festivals or bonus issuance periods.
Determine Appropriate Installment Periods
- Short Term (3-6 months): Suitable for products where you want to close sales quickly and manage cost risks regarding installment fees (MDR).
- Long Term (10 months or more): Suitable for High-value or premium-priced products. Use as a special promotion to attract customers who are hesitant about paying the full price.
*Use as necessary and pay back in full on time to avoid interest of 9% - 16% per year.
Benefits for Online Stores Accepting Credit Card Installments
