Australia’s retail technology landscape is shaped by a mix of POS platforms, payments infrastructure, logistics software and in-store media systems that support both ecommerce and physical retail operations. This ranking of top 5 retail technology companies in Australia is based on a hybrid model (structural relevance + scale) rather than pure revenue, reflecting how technology integrates into supermarket and FMCG supply chains. The companies included are Retail Express (Maropost), Shippit, Afterpay (Block), Airwallex and Mandoe Media. Together, they represent core layers of modern retail infrastructure across checkout, payments, delivery, omnichannel operations and in-store engagement.
