or sales account?
The way to propose your objects is to come physically to the company, or send photos and detailed data of the object, so as to have a first evaluation of the product. There are 3 ways you can propose your object:
This assessment if it is in line with its expectations can be followed by a purchase by the company, which after having carried out all the appropriate verifications of authenticity and lawful origin that the seller undertakes to sign on a special contract, will provide for the immediate payment of the goods.
Another possibility is the partial or total trade-in with any object that the customer wanted to buy, at the price of which you can deduct the value attributed to what you want to leave in trade-in, obviously after the necessary checks mentioned above.
The last possibility, but very much in use, is that of the Sales Account. That is, the customer leaves his object on display, without any commitment of time, and after having carried out the usual verifications of authenticity and lawful origin, the company decides to accept it in the state in which it is located, determining the net purchase price for the owner, at which point both parties sign a special contract specifying time (maximum 60 days) amount and method of payment.
