You show up and the tutor asks you to walk through a recent sale, one thing at a time: who bought it, what was sold, when it happened, how much it cost, how it was paid, whether it was delivered or picked up, and how the customer found you. From your answers, it spots the gap: if you say "I remember it in my head," it asks for the written record; if the customer link is missing, it goes back to why that link matters; if the origin is missing, it explains why that also needs to be noted.
It asks what would happen if, today, someone had to answer "how much did I sell to this customer last month" without opening WhatsApp and scrolling through the whole conversation. Every missing field is a question with no quick answer down the road. After rebuilding that logic with you, the tutor asks you to repeat it in your own words: "every sale, I log who bought it, what I sold, when it happened, how much it cost, how it was paid, whether it was delivered or picked up, and how the customer found me."
You leave the session with one request: log one real sale that happens from now on, with all seven details and linked to the customer whenever you can tell who they are. Next time you come back, it asks what you logged and what got left out, checks the record, and fixes only the field that was missing, without repeating everything.
