The Dock platform enables you to process credit card products offered by issuers for their customers.

A credit card is considered a “postpaid” card. The cardholder has a line of credit that is preset by the card issuer, who set this limit by taking into account several factors, such as your monthly income/wage. As the cardholder makes purchases by using the card, the credit limit decreases. It is re-established after the statement is paid.

Registering cardholders

Persons, accounts and cards

The issuer can register their cardholders through Persons and Accounts endpoints and generate their cards through Cards endpoints.

On the Dock platform, these entities interact in the following way:

A person can hold one or more accounts in case the issuer defines in their business rules that each of their customers may have more than one account.

An account can have one or more cards associated. In practical terms: An account can have a physical and a virtual card (two active cards for the same account), an account can have a physical card used by the primary holder of the account and a physical card used by an additional holder of the account, an account can have a physical card that is unblocked and active and a physical card that is canceled for loss.



A card can only be associated with one account and one cardholder. A card is never associated with more than one person or more than one account.

Credit limits

A credit card limit is the amount set by the issuer so that the cardholder is able to spend it when purchasing products and services, including in installments.

Basically, it is the total credit amount that is available for a cardholder to spend in purchases, without the need for having the money in cash at hand.

As the cardholder customer makes purchases, the available limit decreases. In order to re-establish a limit for a card, they must pay the statement by the due date.

On the Dock platform, the credit limit is associated with Accounts.

Payment due date

The payment due date is when the cardholder needs to pay the statement. It is set by the issuer so that the spending is paid without any type of interest.

If the cardholder pays the statement after the payment due date, the issuer usually charges penalties foreseen in their relevant contracts with the cardholder in addition to the interest on the statement’s total amount.



On the Dock platform, the payment due date for the statement is associated with Accounts and you can set a single payment due date per account, among other options for dates that the issuer wants to offer. The most commonly used options for payment due dates are 1, 5, 10, 15, 20, 25.

End of a billing cycle

The end of a billing cycle is the date interval set by the issuer for the cardholder’s spending amount to be charged, thus creating a specific due date.

In other words: It is the day when the spending of the month is compiled, and the statement goes from “open” to “closed”. All purchases you make after that day will be carried for the following month.

The end of a billing cycle varies according to the institution issuing the card, but it is usually a few days before the due date.

On the Dock platform, the issuer can set parameters for the billing cycle by the due date. It can be reviewed as needed and changes can be requested from our Operations team by opening a ticket in the Conductor Self-Service Portal.


A statement is a document gathering detailed information on all purchases the cardholder made throughout the month, whether they’re paid upfront or in installments. Therefore, cardholders can keep track of their spending and understand how it is calculated.

The issuer chooses a form to make the statement available for their cardholders, whether in digital format or printed and sent to the address provided for receiving mail.
