Centralizing information

Good morning. We are starting to develop several small web solutions (We use Laravel) to meet the needs of our client, based on this I came up with a big question. I would like to centralize all information that will be used throughout the projects to stay in one place and each application with its peculiarity in another example: I have a fiscal document module and a request document, I would like to centralize the customer information in one place so that both the request module and the fiscal document module access the same information. Any suggestions on how I can do this?
