Firebase synchronize company data only

I have about 200 companies that will use the app (android). But I do not want firebase to synchronize all the data of all the companies.

In the example, I want all users in company 1 to only synchronize the sales of company 1.

{
  "ventas": [
    {
      "empresa": "empresa 1",
      "producto": "producto 1",
      "usuario": "usuario 1"
    },
    {
      "empresa": "empresa 2",
      "producto": "producto 2",
      "usuario": "usuario 2"
    },
    {
      "empresa": "empresa 1",
      "producto": "producto 3",
      "usuario": "usuario 3"
    }]
}
