That's right. You can ask for an invoice for the advance payment. You only need to indicate the advance payment on the invoice, and then issue the remaining invoice when the balance arrives. As long as you bring it up, there is no problem.

2. Issue the receipt first, and affix the official seal to indicate that it is the advance payment, and then issue the invoice after paying the full amount.

Issue a full invoice to the payment company first, but there must be a contract stating how long and under what circumstances the balance will be paid. If there is a breach of contract, be sure to write it clearly. If there is any problem, it will be arbitrated by the court.

In fact, these things are all alive, just according to the regulations of different companies. Therefore, it can be handled flexibly according to the company's regulations, integrity and other specific circumstances.

Advance payment is a means of payment, and its purpose is to solve the shortage of liquidity of one party to the contract. Advance payment does not guarantee the performance of the debt, nor can it prove the establishment of the contract. If the party receiving the advance payment defaults, it only needs to return the money received, and it is not necessary to return it twice. In addition, the law has strict regulations on the use of advance payment, and the parties may not set any advance payment in the contract, but there is no such restriction on the advance payment.
