Post-purchase credit offer and tender switch

1. A computer-implemented method, comprising:

determining a completion of a transaction at a point-of-sale system, wherein the completed transaction is held as a pending transaction until authorization for fulfillment of the transaction is provided, and wherein the completed transaction specifies a selected payment instrument associated with a customer;

receiving an application for a new line of credit associated with a preferred payment instrument, wherein the application indicates contact information associated with a user device of the customer, and wherein the application is offered independent of the transaction;

using a trained machine learning algorithm to generate an offer to switch the completed transaction from the selected payment instrument to the preferred payment instrument while the completed transaction is held as the pending transaction, wherein the machine learning algorithm is trained using a training dataset including historical transaction data associated with other customers;

transmitting the offer, wherein the offer is transmitted using the contact information, and wherein when the offer is received by the user device of the customer, the user device presents the offer and an indication that the application is approved;

detecting acceptance of the offer;

switching the completed transaction to the preferred payment instrument;

authorizing the fulfillment of the completed transaction; and

determining that the completed transaction is no longer being held as the pending transaction, wherein the trained machine learning algorithm is further trained based on the completed transaction and the acceptance of the offer.

2. The computer-implemented method of claim 1 , wherein the offer specifies one or more incentives for switching the completed transaction from the selected payment instrument to the preferred payment instrument.

3. The computer-implemented method of claim 1 , further comprising:

determining available credit associated with the preferred payment instrument, wherein the available credit is used to generate the offer.

4. The computer-implemented method of claim 1 , wherein the offer is generated subject to an expiration, and wherein the offer is rescinded as a result of the expiration.

5. The computer-implemented method of claim 1 , wherein the offer includes an option to split the completed transaction between the selected payment instrument and the preferred payment instrument.

6. The computer-implemented method of claim 1 , wherein the offer is transmitted to the user device through a Short Message Service (SMS) message, and wherein the SMS message is transmitted using the contact information.

7. The computer-implemented method of claim 1 , wherein the application is offered through a website, and wherein the website is independent of the point-of-sale system.

8. 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:

determine a completion of a transaction at a point-of-sale system, wherein the completed transaction is held as a pending transaction until authorization for fulfillment of the transaction is provided, and wherein the completed transaction specifies a selected payment instrument associated with a customer;

receive an application for a new line of credit associated with a preferred payment instrument, wherein the application indicates contact information associated with a user device of the customer, and wherein the application is offered independent of the transaction;

use a trained machine learning algorithm to generate an offer to switch the completed transaction from the selected payment instrument to the preferred payment instrument while the completed transaction is held as the pending transaction, wherein the machine learning algorithm is trained using a training dataset including historical transaction data associated with other customers;

transmit the offer, wherein the offer is transmitted using the contact information, and wherein when the offer is received by the user device of the customer, the user device presents the offer and an indication that the application is approved;

detect acceptance of the offer;

switch the completed transaction to the preferred payment instrument;

authorize the fulfillment of the completed transaction; and

determine that the completed transaction is no longer being held as the pending transaction, wherein the trained machine learning algorithm is further trained based on the completed transaction and the acceptance of the offer.

9. The system of claim 8 , wherein the offer specifies one or more incentives for switching the completed transaction from the selected payment instrument to the preferred payment instrument.

10. The system of claim 8 , wherein the instructions further cause the system to:

determine available credit associated with the preferred payment instrument, wherein the available credit is used to generate the offer.

11. The system of claim 8 , wherein the offer is generated subject to an expiration, and wherein the offer is rescinded as a result of the expiration.

12. The system of claim 8 , wherein the offer includes an option to split the completed transaction between the selected payment instrument and the preferred payment instrument.

13. The system of claim 8 , wherein the offer is transmitted to the user device through a Short Message Service (SMS) message, and wherein the SMS message is transmitted using the contact information.

14. The system of claim 8 , wherein the application is offered through a website, and wherein the website is independent of the point-of-sale system.

15. 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:

determine a completion of a transaction at a point-of-sale system, wherein the completed transaction is held as a pending transaction until authorization for fulfillment of the transaction is provided, and wherein the completed transaction specifies a selected payment instrument associated with a customer;

receive an application for a new line of credit associated with a preferred payment instrument, wherein the application indicates contact information associated with a user device of the customer, and wherein the application is offered independent of the transaction;

use a trained machine learning algorithm to generate an offer to switch the completed transaction from the selected payment instrument to the preferred payment instrument while the completed transaction is held as the pending transaction, wherein the machine learning algorithm is trained using a training dataset including historical transaction data associated with other customers;

transmit the offer, wherein the offer is transmitted using the contact information, and wherein when the offer is received by the user device of the customer, the user device presents the offer and an indication that the application is approved;

detect acceptance of the offer;

switch the completed transaction to the preferred payment instrument;

authorize the fulfillment of the completed transaction; and

determine that the completed transaction is no longer being held as the pending transaction, wherein the trained machine learning algorithm is further trained based on the completed transaction and the acceptance of the offer.

16. The non-transitory, computer-readable storage medium of claim 15 , wherein the offer specifies one or more incentives for switching the completed transaction from the selected payment instrument to the preferred payment instrument.

17. The non-transitory, computer-readable storage medium of claim 15 , wherein the executable instructions further cause the computer system to:

determine available credit associated with the preferred payment instrument, wherein the available credit is used to generate the offer.

18. The non-transitory, computer-readable storage medium of claim 15 , wherein the offer is generated subject to an expiration, and wherein the offer is rescinded as a result of the expiration.

19. The non-transitory, computer-readable storage medium of claim 15 , wherein the offer includes an option to split the completed transaction between the selected payment instrument and the preferred payment instrument.

20. The non-transitory, computer-readable storage medium of claim 15 , wherein the offer is transmitted to the user device through a Short Message Service (SMS) message, and wherein the SMS message is transmitted using the contact information.

21. The non-transitory, computer-readable storage medium of claim 15 , wherein the application is offered through a website, and wherein the website is independent of the point-of-sale system.
