recording of revenue

I hope you are doing well. I have a query regarding one of my clients who operates three different business units: 1. Sale of salon products (e.g., hair extensions), recorded in Square. 2. Provision of salon services, recorded in StyleSeat software. 3. Provision of cleaning services, recorded in a separate cleaning software. I have the revenue report extracts from each source, but I am struggling with how to properly record the inventory, sales, and receivables across these business lines. Could you kindly guide me on the correct double-entry treatment for these items?
