Marketplace Development
A marketplace platform connects multiple independent sellers with buyers on one platform, taking a commission on each transaction — the storefront and browsing experience is the visible part, but the genuinely hard engineering problem is seller onboarding, commission calculation, and split settlement, which must be correct to the transaction every time since it involves real money owed to real third parties. Beacon Coders builds these from a proven module set covering multi-vendor listings and payment splitting, with settlement logic treated as the highest-scrutiny part of the build. Projects start at ₹7,00,000 / $8,400 and typically run 18 to 32 weeks, the longest timeline among our solutions after ERP.
The standard module set
Every marketplace build includes seller onboarding with verification and profile management, product or service listing management per seller, a unified buyer-facing catalogue and checkout across all sellers, commission calculation and split payment settlement, and seller-facing dashboards for order and payout tracking. Rating and review systems for both buyers and sellers round out the standard set.
Why split settlement is the module that determines whether the platform works
When a buyer pays for an order from a specific seller, that payment needs to be split correctly between the seller's payout (minus commission), the platform's commission revenue, and any applicable taxes, then settled to the seller on a defined schedule — and this needs to reconcile exactly, every time, because errors here mean sellers are paid incorrectly, which is the fastest way to lose the supply side of a marketplace. We build this using payment gateway split-payment features (Razorpay Route or Stripe Connect, depending on your markets) rather than manual reconciliation, with automated matching between orders, commissions, and payouts, and clear audit trails for every settlement.
What typically needs customising
Commission structure varies significantly — flat percentage, tiered by seller volume, or category-specific rates — and is rarely a single fixed number across an entire marketplace. Seller verification depth (basic registration versus document verification versus in-person checks) depends on your risk tolerance and category, and dispute resolution workflows for buyer complaints against a specific seller need rules matched to how your platform wants to handle liability.
Integration points
Marketplaces typically integrate with a split-payment-capable gateway (Razorpay Route, Stripe Connect), SMS or email for order and payout notifications, shipping or logistics APIs where physical goods are involved, and in some cases a KYC verification service for seller onboarding compliance.
When to build a smaller platform instead of a full marketplace
If you have not yet validated that independent sellers actually want to list on your platform, starting with a simpler single-vendor store or a manually managed pilot with a handful of sellers is a lower-risk way to test demand before committing to full marketplace infrastructure. Marketplace development earns its cost once you have real two-sided demand validated and need to scale beyond what manual seller management and ad hoc payment splitting can handle reliably.
Frequently asked questions
Through automated split-payment processing using gateway features built for this — Razorpay Route or Stripe Connect — rather than manual calculation and transfer, with every order's commission and payout amount calculated and recorded at the point of transaction, and a reconciliation report that flags any mismatch for review before it becomes a seller-facing problem.
Whatever structure fits your business — flat percentage, tiered rates based on seller volume or tenure, category-specific commission rates, or a combination. This is scoped during discovery against your actual monetisation strategy rather than built as a single hardcoded rate.
Verification depth is scoped to your platform's risk profile — basic business registration and identity checks for lower-risk categories, more thorough document and sometimes in-person verification for higher-risk ones like financial services or regulated goods. We recommend a verification level rather than default to the lightest option, since under-verification is a common cause of marketplace trust problems later.
We build a dispute workflow into the platform — buyers can flag an order issue, sellers can respond, and admin staff can review and resolve, including reversing a settlement if warranted — with rules for who bears liability in different dispute types agreed with you during discovery rather than decided ad hoc after the first real dispute occurs.
Yes, though physical goods add shipping and logistics integration requirements that digital goods do not need — we scope this explicitly during discovery, since a marketplace mixing both often needs different fulfilment logic per listing type.
We test settlement logic extensively against edge cases — refunds, partial refunds, disputed orders, seller account suspension mid-transaction — before launch, and recommend a limited pilot with a small group of real sellers processing real but modest transaction volume before opening the platform broadly, so any remaining edge case surfaces at low stakes rather than at scale.
Yes, seller-level storefront customisation — a profile page, branding elements within platform limits, and their own product catalogue view — is a common part of the seller dashboard, scoped to whatever degree of seller brand identity fits your marketplace's positioning without compromising the unified buyer experience across the platform.
