Marketplaces built to handle real transaction volume
We build two-sided and multi-vendor marketplace platforms with the vendor management, payment splitting, and trust systems needed to scale.
Overview
A marketplace isn't a normal e-commerce site with extra steps, it's fundamentally a trust and coordination problem wearing an e-commerce interface. You're not just selling products or services, you're managing relationships between buyers and sellers who've never met, handling money that needs to be split correctly and paid out reliably, and building enough trust signals that a stranger feels comfortable transacting with another stranger through your platform.
This creates technical challenges that a standard online store never encounters: vendor onboarding and verification flows, commission logic that needs to handle disputes and refunds correctly across multiple parties, search and discovery systems that need to surface the right vendor to the right buyer among potentially thousands of listings, and review systems robust enough to build genuine trust without being easily gamed.
We've built this category of platform before, for physical goods, digital products, and bookable services alike, and we design around these specific failure points from day one rather than discovering them after launch when real vendors and real money are already flowing through the system. The goal is a marketplace that can scale from your first handful of vendors to thousands without hitting the architectural walls that undersized marketplace platforms inevitably run into.
What we build
The full technical foundation your marketplace needs to connect buyers and sellers reliably at scale.
Vendor Onboarding & Management
The vendor side of a marketplace is often more complex than the buyer side, since vendors need tools to manage listings, track orders, monitor payouts, and understand their own performance, essentially a mini business dashboard within your platform. We build self-serve vendor registration with appropriate verification steps to keep quality and trust high, along with management dashboards that give vendors genuine visibility into their orders, inventory, and earnings without requiring them to contact you for basic information. Getting vendor onboarding friction right matters enormously for marketplace growth: too much friction and quality vendors won't bother joining, too little and you risk quality or trust issues that damage the buyer experience. We calibrate this specifically to your marketplace's risk profile and target vendor type.
Split Payments & Payouts
Money in a marketplace flows through you before reaching vendors, which means commission calculation, payout timing, and handling refunds or disputes all need to work correctly and transparently or you'll face vendor trust issues fast. We build automated commission splitting and payout logic on proven payment infrastructure designed specifically for marketplace use cases, handling the genuinely tricky scenarios: partial refunds that need to be split proportionally, disputed transactions that need to be held pending resolution, and payout scheduling that balances vendor cash flow needs against your own risk management. This isn't standard e-commerce checkout logic adapted for multiple sellers, it's fundamentally different payment architecture built for multi-party transactions from the ground up.
Search, Discovery & Trust Systems
A marketplace with thousands of listings and no effective way to find the right one is just a directory nobody uses. We build fast, relevant search and filtering systems tuned to your specific marketplace category, along with review and rating systems designed to build genuine buyer trust without being easily manipulated through fake reviews or vendor gaming. This includes thinking carefully about ranking logic, since how listings get surfaced directly shapes which vendors succeed on your platform and how buyers perceive overall marketplace quality. We also build dispute resolution workflows for the inevitable situations where a transaction goes wrong, since how well your platform handles conflict directly determines whether both buyers and vendors trust it enough to keep coming back.
How we build marketplaces that earn trust from both sides
A process shaped around the two-sided trust problem every marketplace has to solve.
- 01
Marketplace Model & Category Definition
We start by clarifying exactly what kind of marketplace you're building: physical goods, digital products, or bookable services, since each has meaningfully different technical requirements around fulfillment, delivery confirmation, and scheduling. We also define your specific commission structure and vendor verification requirements based on your risk tolerance and target vendor quality bar.
- 02
Payment & Payout Architecture
Given how central money-splitting is to a marketplace, we design the payment and payout architecture early, including how commissions get calculated, how refunds and disputes get handled across multiple parties, and what payout schedule and method vendors will use. Getting this wrong is expensive to fix later once vendors are relying on predictable payouts.
- 03
Vendor-Side Platform Build
We build the vendor onboarding flow, verification steps, and vendor dashboard first in many cases, since you need vendors and inventory on the platform before there's anything for buyers to discover. This includes listing management, order tracking, and payout visibility tools vendors need to run their side of the business through your platform.
- 04
Buyer-Side Search & Discovery Build
With vendor-side infrastructure in place, we build the buyer-facing search, filtering, and discovery experience, tuned to help buyers find the right vendor or listing quickly. This includes the review and rating system that builds the trust signals buyers need to feel comfortable transacting with an unfamiliar vendor.
- 05
Trust, Safety & Dispute Workflow Testing
We test the dispute resolution and refund workflows thoroughly, since these edge cases are where marketplaces most often fail vendors or buyers in ways that damage platform trust. This includes testing scenarios like partial refunds, vendor non-fulfillment, and buyer complaints to ensure the system handles them gracefully rather than requiring manual intervention for every case.
- 06
Vendor Recruitment Launch & Scaling Support
We support your initial vendor recruitment phase technically, ensuring onboarding stays smooth as your first cohort of vendors joins, then continue monitoring platform performance as transaction volume grows. Marketplaces often reveal scaling considerations only under real usage, and we stay engaged through this early growth phase if you choose ongoing support.
Infrastructure built for marketplace scale
We use technologies proven to handle high-volume, multi-party transactions reliably.
Frequently Asked Questions
Yes, we build automated commission and payout logic using payment infrastructure specifically designed for marketplace and multi-party transactions, so vendors get paid accurately and on a predictable schedule. This includes handling the trickier scenarios correctly, like partial refunds that need to be split proportionally between your commission and the vendor's payout.
We implement structured review systems, seller verification steps appropriate to your risk tolerance, and clear dispute resolution workflows that give both buyers and vendors a fair, documented process when something goes wrong. How aggressive verification needs to be really depends on your specific marketplace category and transaction values involved.
Yes, we design the data architecture, search infrastructure, and database indexing specifically to handle high vendor and listing volume from the start, rather than architecture that works fine with fifty vendors but degrades badly at five thousand. This forward planning is significantly cheaper than retrofitting scalability after the fact.
Yes, this is actually the approach we usually recommend. We typically launch with core buying, selling, and payment flows first, validate that vendors and buyers are actually using the platform as expected, then layer in more advanced features like saved searches, subscriptions, or loyalty programs based on real usage patterns rather than guessing upfront.
Yes, we've built marketplaces across physical goods, digital products, and bookable services, each of which has genuinely different technical requirements. Physical goods need shipping and fulfillment tracking, digital products need secure delivery and licensing, and bookable services need scheduling and calendar management, so we tailor the architecture to your specific category.
Yes, we can build multi-vendor cart and checkout functionality where a buyer purchases from several vendors in a single transaction, then automatically splits the payment and shipping logistics behind the scenes. This is more complex than single-vendor checkout but significantly improves the buyer experience for marketplaces with smaller individual order values.
Yes, marketplace-specific platforms like Sharetribe can be a faster starting point for validating a marketplace concept, and we can build on top of these where appropriate. That said, highly custom commission structures, unique vendor workflows, or specific compliance requirements often push toward a fully custom build, and we'll give you an honest recommendation based on your specific needs.
Yes, we design vendor tiers and permission levels to differentiate between individual sellers and larger business accounts, including different commission rates, bulk listing tools, or dedicated account features for higher-volume vendors if that fits your marketplace strategy. This flexibility is built into the vendor management system rather than requiring separate platforms.
