You're not supposed to reuse an address: https://en.bitcoin.it/wiki/Address_reuse

> Address reuse refers to the use of the same address for multiple transactions. It is an unintended practice, abusing the privacy and security of the participants of the transactions as well as future holders of their value. It also only functions by accident, not by design, so cannot be depended on to work reliably

You should use a deterministic wallet and generate a new address for every transaction.

You can use https://btcpayserver.org to generate such thing.
