Frequently Asked Questions
Clear answers to common questions about building your marketplace platform with CIS.
What is the typical cost for a marketplace MVP?
While it varies, a typical MVP for a marketplace app with core features (user profiles, listings, basic payments, reviews) generally ranges from $25,000 to $75,000. The final cost depends on platform complexity (web vs. mobile), UI/UX design intricacy, and specific third-party integrations. Our interactive calculator can give you a good starting estimate.
How long does it take to build a marketplace app?
An MVP can typically be designed, developed, and launched in 3 to 6 months. More complex platforms with advanced features like escrow, dispute resolution, and extensive integrations can take 6 to 9 months or longer. Our phased, blueprint-based approach helps accelerate this timeline by building on proven modules.
How do you handle complex payment splitting and escrow?
We specialize in this. We use powerful payment platforms like Stripe Connect and Adyen for Platforms, which are specifically designed for marketplaces. We configure them to automatically split payments between vendors and the platform, handle multi-vendor carts, manage delayed payouts, and hold funds in escrow until transaction conditions are met, ensuring security for all parties.
Do I own the source code and intellectual property?
Absolutely. Upon final payment, we transfer 100% of the intellectual property and source code to you. There are no licensing fees or hidden clauses. Our SOC 2 compliant processes ensure your IP is protected throughout the development lifecycle.
What happens after my marketplace is launched?
Launch is just the beginning. We offer flexible and comprehensive support and maintenance packages to ensure your platform remains secure, updated, and performs optimally. We can also work with you on a retainer or dedicated team basis to continuously add new features and scale your platform as your business grows.
