Latest/Marketplace Development
Marketplace builds run $15,000 to $150,000+. Where yours lands depends on the marketplace model, whether the platform holds money before paying sellers, how much trust the transaction needs, and how many separate apps you build.

A custom WMS is worth building when daily floor tasks need workarounds. Store stock as a movement ledger, design scanning for speed and dropped Wi-Fi, scope each integration including COD returns, and go live on receiving and counts before picking.

A build-order guide to an event marketplace: model venues, vendors and talent separately, build supply and availability first, treat bookings as a state machine with database-level double-booking prevention, hold funds until delivery, and add ML personalization only once booking history exists.

An app like Porter is three products: shipper app, driver app and an operations panel where verification, disputes and payouts live. Decide fixed pricing or bidding first, ship a ranked-list dispatcher, hold funds until delivery, and budget from team-weeks.

Latest/MVP Development
Indian MVP quotes differ by rate, seniority mix, design, scoping and what 8 weeks contains. A paid two-week scoping step lowers the build price by removing uncertainty. Week-by-week build table, Denti360 worked example, and the post-launch reserve to hold back.
