The task is not easy.

Create a system that will display car listings from the two largest American auctions (Copart and IAAI), through which bids will be placed on cars. Purchases will be made through our personal Copart and IAAI auction accounts. The system must have:

1. the ability to create personal accounts with a form requiring personal data (phone, email, address, etc.);

2. the ability to accept payments (integration of a payment system), deposit in the form of a selected plan;

3. a built-in calculator on the page to help calculate all expenses;

4. the ability to make “Pre-Bid” and “Buy Now” bids:

The participant sets the maximum amount they are willing to pay for the selected car. Once the bid in our auction system is accepted, the system will start bidding during the live auction of the auction house (Copart or IAAI). 

The car auction in the USA is divided into two consecutive stages: 

preliminary bidding (Pre-Bid) – a bidding process lasting several days and starting from $0 

live auction – a fast auction starting from the highest bid from the preliminary bidding. If there are no interested parties, the highest bid from the preliminary bidding wins. 

In case the user's bid in our system exceeds the preliminary (Pre-Bid) maximum bid of the auction house, our automated system represents our user by gradually increasing bids at the live auction up to the maximum amount set by the user, thereby ensuring the highest auction efficiency and the possibility of purchasing the car at the lowest possible price. 

5. Automatically generate invoices;

6. Automatic notifications via SMS and email about status changes;

7. A page with data and status tracking for each car that will be exported through our company from the USA to other destination countries. An example can be: https://w8shipping.com/tracking/?lot=&vin=484411&searchAuto=Search+%C2%BB

The project is not simple and to better understand our initial desired results and all details,
here is an example: https://bid.cars/ru/ in the future, the functions may be expanded. 

I don't know if there are specialists here, but there are more complex systems with broader functionality, options to make all types of bids - “Pre Bid”, “Buy Now”, even “Bid Live”, etc. Examples: https://sca.auction/ru        https://www.autobidmaster.com/ru/    https://www.salvagebid.com/ru
