Core Scope & Deliverables
Architecting Two-Sided Digital Marketplaces in Europe
A marketplace application is fundamentally more complex than a standard e-commerce store because it handles distinct workflows for buyers and vendors while complying with European financial regulations (PSD2/SCA).
Estimated Investment by Component:
- Vendor Onboarding & KYC Identity Verification: €2,200 – €4,000
- Catalog Management & Multi-Vendor Inventory: €2,800 – €5,200
- Stripe Connect Split Payouts & Escrow: €2,500 – €4,800
- Cross-Platform Mobile App (iOS & Android): €4,500 – €8,500
Total engineering budgets for a market-ready two-sided MVP generally range between €9,000 and €28,000.
Frequently Asked Questions (FAQ)
Is the estimated project budget binding?
The price range represents an accurate estimate based on completed production implementations. Following an initial architecture consultation, I prepare a fixed-price milestone specification for your MVP.
Who retains ownership of the source code and intellectual property?
100% of the source code, Git repositories, and intellectual property belong exclusively to your company. I charge zero hidden recurring licensing fees or transaction commissions.
How long does it take to design and launch an MVP?
Using proven architectural patterns and Flutter / Next.js, I typically deliver the first fully functional production version within 6 to 10 weeks.
Do you offer ongoing SLA maintenance after deployment?
Yes, I provide dedicated SLA technical support covering proactive monitoring, dependency updates, and guaranteed response times.
