Post-purchase credit offer and tender switch

A system, comprising:

• one or more processors;
• and
• memory storing thereon instructions that, as a result of being executed by the one or more processors, cause the system to:
• detect completion of a transaction at a retailer, wherein when the transaction is completed at the retailer, transaction information is submitted and the transaction is held as a pending transaction until authorization for fulfillment of the transaction is provided
• receive the transaction information associated with the transaction, wherein the transaction information specifies a selected payment instrument and contact information for a customer corresponding to the transaction;
• receive input corresponding to a selection of payment information associated with the selected payment instrument;
• generate a determination using the payment information and the contact information;
• train a machine learning algorithm using sample transaction data, wherein training includes identifying one or more recipients for offers to switch transactions to a preferred payment instrument while the transactions are held as pending transactions;
• use the machine learning algorithm to generate an offer to switch the transaction from the selected payment instrument to the preferred payment instrument while the transaction is held as the pending transaction, wherein the offer to switch is from the selected payment instrument to the preferred payment instrument;
• receive a request to switch the transaction from the selected payment instrument to the preferred payment instrument while the transaction is held as the pending transaction;
• switch the transaction to the preferred payment instrument from the selected payment instrument, wherein switching the transaction causes the authorization for fulfillment of the transaction to be provided;
• and
• complete the transaction using the preferred payment instrument, wherein the transaction is changed from the pending transaction to a completed transaction, and wherein the completed transaction is used to train the machine learning algorithm.

A non-transitory, computer-readable storage medium storing thereon executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to:

• detect completion of a transaction at a retailer, wherein when the transaction is completed at the retailer, transaction information is submitted and the transaction is held as a pending transaction until authorization for fulfillment of the transaction is provided;
• receive the transaction information associated with the transaction, wherein the transaction information specifies a selected payment instrument and contact information for a customer corresponding to the transaction;
• receive input corresponding to a selection of payment information associated with the selected payment instrument;
• generate a determination using the payment information and the contact information;
• train a machine learning algorithm using sample transaction data, wherein training includes identifying one or more recipients for offers to switch transactions to a preferred payment instrument while the transactions are held as pending transactions;
• use the machine learning algorithm to generate an offer to switch the transaction from the selected payment instrument to the preferred payment instrument while the transaction is held as the pending transaction, wherein the offer to switch is from the selected payment instrument to the preferred payment instrument;
• receive a request to switch the transaction from the selected payment instrument to the preferred payment instrument while the transaction is held as the pending transaction;
• switch the transaction to the preferred payment instrument from the selected payment instrument, wherein switching the transaction causes the authorization for fulfillment of the transaction to be provided;
• and
• complete the transaction using the preferred payment instrument, wherein the transaction is changed from the pending transaction to a completed transaction, and wherein the completed transaction is used to train the machine learning algorithm.
