Marketplace Platforms
Build a marketplace where many sellers can grow with you
We build online marketplaces where many sellers list their products, with simple seller sign-up, automatic commissions, and reliable payouts handled for you.
In plain English
What is it, in plain English
A multi-vendor marketplace is one website where many different sellers sell their products. Customers shop in one place, but the items come from many sellers.
Think of a farmers market. You run the market. Each vendor runs their own stall. Shoppers walk through, buy from different stalls, and pay at one checkout. You collect a small fee from each sale, and each vendor gets the rest. A marketplace platform is the software that runs that market online.
How it works
How it works
- 01
Sellers sign up
They create an account, share their business details, and agree to your terms.
- 02
You approve them
You review each seller before they can start selling.
- 03
Sellers list products
They add items, prices, photos, and stock from their own seller dashboard.
- 04
Customers shop and pay once
Shoppers can buy from several sellers in a single checkout.
- 05
The money is split automatically
Your commission is kept, and each seller's share is paid out on a schedule.
Use cases
What you can do with it
Seller onboarding
Guide new sellers through sign-up, identity checks, and setup step by step.
Seller dashboards
Give each seller their own space to manage products, orders, and earnings.
Flexible commissions
Set fees by seller, category, or product, such as a percentage or a flat fee.
Automatic payouts
Pay sellers on a regular schedule without manual bank transfers.
Reviews and ratings
Let customers rate sellers and products to build trust.
Rules and moderation
Approve products, handle disputes, and keep the marketplace safe.
Why it matters
Why it matters for your business
A marketplace lets you offer a much bigger range of products without buying or storing them yourself.
- More choice for customers. Many sellers means more products in one place.
- Less stock risk. Sellers own their inventory, so you don't tie up cash in stock.
- Steady income. You earn a commission on every sale.
- Less admin. Sign-up, commissions, and payouts run automatically.
- Built to grow. Adding a new seller doesn't mean adding a new spreadsheet.

How is a marketplace different from a regular online store?
A regular store sells your own products. A marketplace lets many sellers sell their products on your site, and you earn a fee from each sale.
How do sellers get paid?
Payments are split automatically at checkout. Each seller's share is sent to their bank account on the schedule you choose.
Can I charge different commissions for different sellers?
Yes. You can set fees by seller, product category, or individual product.
How do I make sure sellers are trustworthy?
You approve every seller before they can sell. We can add identity checks, product reviews, and customer ratings.
Should I use an existing platform or build from scratch?
It depends on your goals and budget. Existing platforms are often faster to launch. Custom builds offer more control. We'll help you choose.
Who handles taxes and refunds?
We set up your marketplace to follow the rules you choose, and payment services can help with tax reporting. We recommend checking tax questions with your accountant.
