The shelf rental model brings together two parties with complementary needs: a retailer with spare capacity and a maker who needs a physical point of sale. The maker pays either a fixed monthly rental for a defined space or a commission on every unit sold. The retailer handles operations, the till, and customer footfall. The maker manages stock, replenishment, and visual merchandising. The key to a working arrangement is a clear written contract that sets out the rights and obligations of both parties — including terms for unsold goods, changes to shelf position, and early termination.
