If it is really foreign trade and the buyer is abroad, the most commonly used payment methods are telegraphic transfer and letter of credit, and there is a less used collection (because it is not as safe as the first two). Generally speaking, European and American countries like to use letters of credit for bulk transactions. Letters of credit are troublesome to operate and costly. If the operation is improper, the safest payment method will also become very unsafe. Not suitable for small trading companies or amateurs. Regarding the specific operation mode of letter of credit, you can buy books on foreign trade or search online.

So now it's just t/t. If it's by sea, charge him 30% deposit before production, and tell him your account number, bank and specific address of the bank. Tell him to transfer the money to this account. Ask him to fax/scan the transaction receipt to you after printing. Then arrange production for him after the money really arrives.

After the big goods are produced, our company can usually deliver them to him first and ask him to transfer the balance to our account. When the money arrives, send him the ocean bill of lading, certificate of origin, etc. If there is no ocean bill of lading, even if the goods arrive in Hong Kong, he can't bring them out, and the shipping company won't release the goods until it sees his bill of lading.

If it is by air, the goods can only be delivered after the payment of 100% is recovered before delivery. Because the air waybill is not a proof of delivery.

Anyway, remember that you can say anything when the money arrives. It's no use signing a contract. Now many guests don't give a deposit. They don't want a lot of money after signing the contract and making the goods.
