Grocery and kirana
Grocery selling is decided by two things: how fast a bill can be made, and whether the shelf actually has the item. StoreB is built around those — the counter bills by barcode, and the online store reads the same stock figure instead of a second list maintained by hand.
A kirana counter cannot wait for a form. Products are found by name or scanned by barcode, added to the bill, and paid in one flow.
The common failure in grocery is selling online what was already sold at the counter. StoreB writes every sale as an inventory movement, so the count a customer sees is the count the shop has.
Groceries are usually delivered close by, often the same day. The delivery settings reflect that rather than defaulting to a national courier.
