Software for a hardware shop that you describe in plain words

Where it starts

Its stock was kept in a notebook and an old spreadsheet. The business in this demonstration: One store, six staff.

This is a product demonstration with a made-up business, not a customer story.

Popular items kept running out. Every sale lowers the count, and anything at its reorder point goes on one list: what to order, and from whom.
Other things sat on the shelf for months. Ask which items are not moving and get the list, with how much shelf value they hold.
Supplier orders, bills and delivery dates were lost track of. Each order carries its due date and what is owed; a late delivery or a bill coming due is flagged without anyone checking.
No way to see at a glance what sells and what does not. One page for the owner: best sellers, slow movers, what will run out and what is owed.

Suppliers and what we owe, for Owner only: Every unpaid bill by supplier, with what is overdue and what falls due this week. Marking a bill paid takes one step.
At a glance: deliveries and bills, for Owner: Part of the owner's opening page: which deliveries are late, and how much is owed, overdue and due within a week.
Orders and deliveries, for Staff and owner: Part of the orders page: open orders sorted by what is late, due today and due this week.

The crew planned the low-stock and delivery-due alerts for the inbox and email, and the automatic stock count, in this session.

Low stock. When an item reaches its reorder point: It joins the order list and the owner is told in the inbox and by email.
Delivery due. When a supplier delivery is due or late: The order is flagged and the owner is told, so nobody has to keep the dates in their head.
Stock count. With every sale recorded at the counter: The count on hand goes down by itself; no second entry in a notebook.

No more double entry. A sale is recorded in a few taps at the counter and stock drops with it. The notebook and the spreadsheet stop needing each other.
The shelf check does itself. The to-order list shows what is low, how long it will last and which supplier to call, so reordering stops being guesswork.
Supplier money in plain sight. Late deliveries and overdue bills sit on the owner's first page, so nothing owed slips past its date unnoticed.
