Whatever kind of shop you run
One system serves all of them, but a kitchen and an electronics shop are not the same problem. Here is where DERSA treats them differently.
Restaurants
Cooked to order, which means the kitchen needs time before anybody should be sent to collect.
What is different: DERSA waits for your preparation time before it sends a courier, and hot food goes to a courier with an insulated box rather than whoever happens to be nearest.
Grocery
Fruit, vegetables and staples, picked from shelves rather than cooked.
What is different: No preparation wait, a bigger basket, and a courier picked for what the order weighs rather than how fast it will cool.
Mini markets
The corner shop. Small baskets, picked in a minute, several an hour.
What is different: Built for volume rather than size of order: short hops, quick acceptance, and a list a shopkeeper can keep right from a phone.
Retail
Electronics, home goods, stationery: anything that is not food.
What is different: The courier is matched to what the item actually is. A television is not a motorbike job, and DERSA will not pretend otherwise by sending one.
Pharmacy
Over the counter only.
What is different: DERSA does not carry prescription-only medicine, and listing an item marked as such is refused rather than quietly allowed. That needs a pharmacy licence, a pharmacist's check and EFDA rules this platform does not implement. Orders are handed to the person receiving them, not left at a gate.
