Wanting to build a multivendor portal where sellers can list wheelchairs and mobility equipment. Most sellers are stores and have delivery radius so end customer (shoppers) will need to be able to search by location/post code.
For the australian disability and aged care market so payments will need to be in reference to a payment provider and wont be immediately checked out through stripe etc .(offline payment)
