You are absolutely right that developing a high-end competitive shopping app like Amazon with state-of-the-art-design and code can take seven or eight figures development cost, that is depending upon the list of features that you preferred to integrate. But it doesn’t mean that the app can’t be built with MVP or basic features with the starting price of $20k to $50k.
If you really noticed just about the statement “However the initial cost can be as low as $5000 to $10,000+ for the single platform, rest experts can reveal the price of the development as per your choices and preferences.”, I have clearly stated that the OVERALL COST can be starting from $20,000 to $50,000+.
The blog posts are here to provide a rough estimation of the app structure, features, tech stacks, and estimated cost and time. But I always recommend businesses, startups, or users to always consult with the experts for the accurate pricing and development time as per your project needs.
Thanks.
