Hi, I can help design and build the marketplace payment flow so client payments, commission splits, seller payouts, and KYC work smoothly and stay compliant. I’ve delivered full-stack marketplace systems and payment workflows, including buyer-to-platform-to-professional payout logic, provider integration, and onboarding flows. My approach would be to first define the MVP around: Onboarding and role setup Payment provider integration (MangoPay, Lemonway, or Stripe Connect) KYC/AML checks Commission, VAT, and reporting logic Basic admin controls This reduces the risk of issues later with escrow, verification, cross-border payouts, or compliance. I can also help determine whether the MVP should launch in one country first or support Spain and LATAM from day one. Timeline: after reviewing your requirements, I can quickly map the flow and implementation plan, then move into MVP development in phases. If you’d like, I’m available to discuss the best launch scope and payment architecture in Freelancer chat or a video call.

Hi, When you mention "starting from zero," are you looking to launch a basic MVP first (just core payment splits and KYC), or do you need the card issuance and multi-region payout infrastructure built in phase one? I've built two marketplace platforms with Mangopay and Lemonway integrations, handling split payments and KYC flows across Spain and LATAM. Happy to map out the scope and timeline once I understand your phasing. Regards, Nurul Hasan

Hello, I’m interested in building your two-sided freelance marketplace from the ground up, with particular attention to the payment, KYC, commission, wallet, and payout architecture. This project requires more than a standard e-commerce website. The payment flow needs to be designed around marketplace requirements from the beginning so that client payments, platform commissions, professional balances, KYC, and payouts work reliably together. What I can build Modern responsive marketplace frontend Client and professional registration/login Professional profiles and service listings Search, filtering, and marketplace discovery Order/project workflow between clients and professionals Secure client checkout Platform commission calculation Split-payment architecture Professional wallet/payment account functionality Payout management KYC/identity verification integration Admin dashboard I can also structure the system so that the payment layer is modular, making future provider changes easier if your geographic or business requirements evolve. Relevant experience Marketplace projects: [Add your marketplace examples] Payment integrations: [Mangopay / Lemonway / Stripe Connect / other — specify your actual experience] Split payments / payouts: [Briefly describe your actual experience] The priority will be to create a secure, scalable marketplace foundation rather than simply connecting a payment button to a website.

Hello, I’m interested in building your two-sided freelance marketplace from the ground up, with a strong focus on reliable marketplace payments, professional onboarding, KYC, payouts, and a scalable backend architecture. I would build the platform with a clear separation between frontend, backend, payment services, marketplace logic, and administration. Payment and KYC providers should remain the source of truth for regulated payment/identity operations, while our platform maintains the necessary transaction references, states, commissions, and audit records. Webhooks, idempotency, transaction state management, and failure/retry handling will be especially important so that payment events cannot accidentally create duplicate payouts or commissions. For an initial functional MVP, I would first review your exact marketplace workflow, countries, commission model, payout rules, and selected payment provider before giving a fixed delivery estimate. I can provide a milestone-based implementation plan after reviewing those requirements. I’m available for remote collaboration and can communicate in Spanish/English as required. I’d be happy to begin with the technical architecture and payment-provider evaluation before development. Best regards ADEEL

Hey, I’ve carefully reviewed your project, and I understand you need a two-sided marketplace where payments, commission splits, professional payouts, and KYC are handled reliably across Spain, Europe, and LATAM. I can help build the platform with the payment architecture designed around compliance and scalable marketplace operations from the start. I will develop the frontend/backend, integrate Mangopay, Lemonway, or Stripe Connect, implement split payments and payout flows, build professional onboarding/KYC, and provide an admin panel for commissions, VAT, reporting, and platform management. I’ll also handle deployment and clear technical documentation. I have hands-on experience with similar marketplace and payment-integration projects and would be happy to share relevant examples during our discussion. One quick question: Do you already have a preferred payment provider between Mangopay, Lemonway, and Stripe Connect, or should I recommend one based on your target countries and payout requirements?

Hi there, I understand you're building a marketplace where client payments are held in escrow. Upon project completion, the system will automatically split the payment, deducting your platform's commission and VAT before transferring the balance to the professional's wallet. Professionals must complete a compliant KYC process before they can initiate payouts to their bank accounts. Technical approach: We'll build a robust API using Laravel or Node.js with a React frontend. The complex payment logic will be handled via deep integration with Stripe Connect or Mangopay for managed KYC onboarding, e-wallets, automated split payments, and payouts. The platform will be deployed on a scalable AWS infrastructure. Core modules: 1) Onboarding & KYC: A streamlined flow that integrates the payment provider's identity verification. 2) Escrow & Automated Split Payments: The core engine for holding funds and distributing them post-commission. 3) Professional Wallet & Payouts: A dashboard for professionals to manage earnings. 4) Admin & Reporting: For complete oversight of users and transactions. Relevant systems: We built Anceller, a two-sided home services marketplace with similar user and payment flows. We also developed Bison360, a complex ERP with integrated Stripe payment processing. Our strategy is to build an MVP focused on the core transaction loop: payment-in, escrow, and split-payout. We will rigorously test all financial logic in a sandbox environment before deploying the APIs and web interfaces. Regards, Rohit

Hello, For a two-sided freelance marketplace, the challenge isn’t simply building profiles and job listings—the real value lies in creating a smooth experience where clients can post projects, freelancers can discover opportunities, submit proposals, and both sides can communicate and work together seamlessly. That’s exactly how we would approach this. Doomshell can handle the complete marketplace: • Client & freelancer profiles and authentication • Project posting, search, filters, and bidding • Proposals, hiring, messaging, and notifications • Milestones, payments, commissions, and invoices • Ratings, reviews, and dispute management • Admin dashboard with reports and controls • Secure APIs and scalable database architecture • Fully responsive web experience Our Suggestion: We recommend starting with a focused MVP covering the complete client-to-freelancer journey, while keeping the architecture scalable for future features such as subscriptions, escrow, advanced freelancer matching, AI recommendations, and additional payment methods. We can take the project from UI/UX and architecture through development, testing, deployment, and ongoing improvements, with clean and maintainable code throughout.

Hello! I am glad to say that i have already developed an Freelance Marketplace that connects clients with professionals while automatically handling client payments, platform commissions, professional payouts, KYC, wallets, escrow, VAT, and reporting across Spain, Europe, and LATAM. I can help build the complete web platform with client and professional accounts, service profiles, secure checkout, automatic payment splitting, commission handling, escrow workflows, professional payment accounts, KYC onboarding, payouts, and a centralized admin panel. I can also integrate Mangopay, Lemonway, or Stripe Connect based on the countries, payment methods, and financial workflows required for your launch. I specialize in full stack marketplace development, payment integrations, multi party payment workflows, KYC onboarding, wallet and payout systems, commission management, and scalable web platforms. I can structure the foundation so additional countries, payment methods, professional services, and virtual or physical card functionality can be introduced without rebuilding the core marketplace. Let’s connect to review your marketplace, payment, escrow, and KYC workflows so we can define a reliable first version that is ready to expand across additional countries and payment methods.
