Chapter 8
How do I make my first sale?
You do not need your setup finished to sell something today — the till works before your day's accounting ceremony does.
Find what the customer is buying, add it to the sale, and take payment — that is the whole first sale. Nobody needs to have opened or closed anything for the day before this works; a shop that never formally opens its register can still sell all day, every day, because refusing a sale for a bookkeeping reason is the one failure this product will not allow at the counter.
What can wait until after the sale
If you step away mid-sale — a customer changes their mind, the phone rings — what you had already added stays exactly as you left it on your own device, so you never lose a half-built sale to an interruption.
Counting the drawer, reviewing the day, reconciling anything — none of that has to happen before or during a sale. It happens afterwards, when there is time, and the system tells you clearly if something from today still needs a look.
