What is the general process of finding a design company? Pay first or read the manuscript first

Pay the deposit first, then look at the draft, then design it in detail, confirm the receipt of the draft, and then pay the final payment.

Pay a deposit first to ensure that both parties can effectively export demand and works. After the deposit, the general designer will give you about two manuscripts for you to choose from, and then decide whether to continue or republish. In this process, the needs of customers should be clear, and designers should be able to understand the needs and give feedback and solutions in time. After this process is successfully completed, there will be a final draft. Then, after the finalization, the designer's work is basically completed. Then, the final payment is needed, and then the project is over.
