How can I make a "Token Counter" in Solana smart contract?

Question

I want to create a "token counter" which value increases after each token sale. I should make a struct, However I don't know how to store it to be able to keep for next contract calling and use that.

Can you help me?

This question can be a matter of opinion and design, but you can create a new on-chain program that handles your token sales. In your program, you'll have accounts to store any data that you need, including a "token counter".
