No interest installments

Interest-free months in Mexico are a very popular sales strategy that benefits both consumers and merchants. As someone interested in implementing this option, it is essential to understand how it works.

Interest-free months allow your customers to make purchases and pay for them in monthly installments, without additional interest. It is an effective strategy to increase sales.

The key points of MSI are:

• Attractive to Customers: Offering interest-free months makes your products or services more accessible to a broader audience. Many consumers prefer to pay in installments to spread the cost of a large purchase over time.
• Increased Sales: The ability to pay in installments can motivate your customers to make larger purchases than they would if they had to pay immediately. This means an increase in the average purchase value.
• Collaboration with Financial Institutions: To offer interest-free months, you collaborate with financial institutions that assume the financial cost of interest in some promotions incentivized by the same institutions. This involves an agreement between your business and the financial institution to offer this option to your customers.
• Requirements and Commissions: When implementing interest-free months, it is important to understand the requirements and possible associated commissions. Financial institutions charge a fee for the service that is offset by increased sales and customer loyalty.
• Promotion and Marketing: Interest-free months are a marketing tool. Advertise this option in your promotional materials and marketing channels to attract more customers.
• Customer Education: It is essential to educate your customers about the interest-free months system. Make sure they understand that they will not be charged additional interest as long as they comply with the payment plan terms.

How MSI Works

Here's how an MSI flow works:

1. The store configures the different monthly payment options by PSP in the DEUNA Admin.
2. The credit card franchise to which it applies and the respective minimum amount for each configured installment are taken into account.
3. The store checkout shows MSI availability when a customer enters the BIN of a card.
4. The customer selects the monthly payment from a dropdown list shown in the checkout.
5. The transaction is sent to the PSP to be processed.

Implement MSI

To implement MSI, send the installment object with a plan_option_id when creating or editing an order.

The API returns options for installments when they are available.

When making the purchase through Create Payment V2, send the plan_option_id associated with the option selected by the user.

Example V1

   {
     "token": "{{order_token}}",
     "card_id": "...",
     ...,
     "installment": {
        "plan_option_id": "{{plan_option_id}}" // here
     },
     ...
   }

Example V2

   {
       "transaction_id": "{{transaction_id}}",
       "amount": {{total_amount}},
       "device_id": "{{$randomUUID}}",
       "order_token": "{{order_token}}",
       "payer_info": {
           "email": "[email protected]" // email of the purchaser
       },
       ...,
       "payment_source": {
           "method_type": "credit_card",
           ...,
           "installment": {
               "plan_option_id": "{{plan_option_id}}" // here
           }
       },
       ...
   }
