The cost of developing a virtual store can vary greatly depending on a number of factors. On average, a small company can expect to spend anywhere from $1000 to $10,000, while an enterprise company can expect to spend upwards of $50,000 to $100,000. The cost will depend on the specific needs of the company, such as the type of ecommerce platform used, the timeframe for launch, and the need for extra apps or developers. Additionally, other professionals such as product photographers may also need to be factored into the overall cost. It's also worth noting that the global virtual reality in retail market size is expected to reach $55 billion by 2028, indicating a growing trend in the use of virtual stores in the retail industry.
