Should a grocery or food store in the GCC try live selling?
Worth trying, on one condition: that buying happens inside the stream. A live session that ends with a link to a product page loses most of the audience at the moment they were most willing.
What trying it actually requires
Start with one seller, one hour, and a small number of items you hold in stock. The failure mode of a first attempt is a catalogue too wide to demonstrate and stock that runs out mid-session.
Live selling works where the product has to be seen moving, worn or demonstrated, and does little where it does not. For a grocery or food store in the GCC, the answer turns on one thing in particular: Grocery margins are thin and baskets are large, so the whole model lives or dies on delivery cost per order.
What is different about the GCC
The GCC is not one market. Payment habits, delivery norms and language expectations differ enough that a single approach underperforms in at least one country.
Payment preference varies by country more than most planning assumes.
What is different about a grocery or food store
The work is not the video. It is buying inside the video, because a link to a product page loses most of the audience.
Where a mobile app comes into it
Weekly reordering is the behaviour, and an app that remembers the last basket removes most of the work.
