Marketplaces we build

Services marketplaces

Customers book local pros, tutors or contractors. Built around availability, quotes, scheduling and job completion.

B2B marketplaces

Companies buy from verified suppliers with quotes, bulk orders, invoices and net payment terms.

Rental marketplaces

Equipment, space or vehicles rented by the hour or day, with calendars, deposits and damage claims.

Multi-vendor product stores

Many sellers in one catalog, each with their own inventory, shipping rules and payouts.

Core marketplace features

A marketplace lives or dies on trust and liquidity. These are the parts we spend the most time on.

Onboarding and verification

Seller and provider sign-up, identity and business checks, document upload and approval queues.

Search and matching

Filters, location search, availability and ranking that show buyers relevant results fast.

Payments and payouts

Split payments, platform fees, held funds released on completion, refunds and seller payouts through providers such as Stripe Connect.

Reviews and disputes

Two-way ratings, review moderation and a dispute flow your support team can actually manage.

Messaging and notifications

In-app chat, email, SMS and push updates that keep both sides moving toward a completed order.

Admin and analytics

Tools to manage users, listings, fees and payouts, plus reports on supply, demand and take rate.

Revenue models we build in

How the platform earns money shapes checkout, payouts and reporting, so we decide it early.

Commission per transaction

A percentage or flat fee taken from each order, calculated per category, seller or volume tier.

Seller subscriptions

Monthly plans for sellers or providers, with limits on listings, leads or features.

Lead and booking fees

Providers pay per qualified lead or confirmed booking, common in local services markets.

Promoted listings

Paid placement in search results and categories, clearly labeled for buyers.

From idea to a live marketplace

  1. Discovery

    We define both sides of the market, the transaction flow, how you earn and which side you will grow first.

  2. Design and prototype

    Clickable flows for buyers, sellers and admins, tested with real users before development.

  3. MVP

    The smallest version that can complete real transactions, often in one city or one category.

  4. Launch and grow

    Analytics, payment monitoring and a roadmap based on where users drop off.

Case study: a car rental marketplace launched in stages

Currux started with a website and a request flow, then grew into a mobile app. The same staged approach works for most marketplaces.

Currux: used-car rental, lease and subscription marketplace

Currux lets people rent, lease or subscribe to a used car without the usual forms, calls and paperwork. We started with a website and grew it into a mobile app for getting a car in minutes.

Why build your marketplace with Orcatec

We have built scheduling, dispatch and payment flows for our own SaaS product, so we know where service transactions break: no-shows, partial payments, refunds and disputes. We plan for those cases from the first sprint.

Many San Diego founders start with a local marketplace for one region before expanding. We can meet in person, help you scope a launch that fits one city and build the platform to scale to more markets later.
