A marketplace website builder that starts with listings and grows into checkout.
Yclas is a marketplace website builder for buy-and-sell sites, niche marketplaces and multi-seller shops. Open with listings, search and messages on your own domain, then add Buy now, one cart for several sellers and your commission on every sale when your market is ready for it. You pay a fixed monthly price, and Yclas takes no cut of what your sellers sell.

One marketplace website builder, four ways to trade.
Most marketplaces do not need checkout on day one. Buyers and sellers first need to find each other. Yclas lets you start where your market is and switch on more as it grows, without moving to other software.

Supply first: listings people can post in a minute.
A marketplace is only as good as what is on it. Sellers post from a phone with photos, a price and the fields your category needs. Buyers filter on those fields, search on a map and save searches that alert them when something new arrives.
- Your own fields per category: size, condition, year, brand, anything you sell by.
- AI listing from a photo on every plan: 50 to 500 a month, by plan.
- Import from a spreadsheet, another script or pasted group posts.

Buy now, stock and orders when you want payment on the site.
Switch on selling and each listing can carry a price, a quantity and shipping. The buyer pays, the seller gets an order to ship, and both follow it from their account. On the Marketplace plan the payment can wait in escrow until the buyer confirms delivery.
- Returns and disputes: the buyer asks, the seller answers, you decide when they disagree.
- Sale prices with start and end dates, and PDF invoices for buyers.
- Digital downloads that only paying buyers can fetch.

A cut of every sale, taken before the seller is paid.
Connect your own Stripe account with Stripe Connect and sellers set up their payouts with Stripe from their account on your site. On each sale your commission stays with you and the rest goes to the seller. Set a percentage, a fixed fee or both, and other rates for some categories or sellers.
- Rates by category or seller, or a rate inside each seller plan.
- A buyer service fee on top, if your market accepts one.
- Without Stripe Connect: buyers pay you, sellers build a balance and ask to withdraw it.

Buyers come back when strangers feel safe.
Reviews of sellers, and after a deal paid on the site, double-blind reviews so neither side can retaliate. ID verified and Verified business badges. A reports queue for your team, banned words, spam checks and, on paid plans, AI moderation that holds suspicious listings for you to look at.
- Safety tips appear in chat when a message looks like a known scam.
- Moderation modes: publish at once, after approval or after payment.

Your brand on every page, and pages Google can read.
Pick one of 109 looks, then change colours, fonts and sections in the visual editor, or describe the change and let the AI page builder make it. Every listing and storefront is a page with clean URLs, structured data and a place in your sitemap.
- Your own domain with SSL, and no Yclas branding on paid plans.
- 40+ languages, and several on one site from Professional.

Three ways to build a marketplace website.
A hosted builder, an open source script on your own server, or software written for you. All three can work; they cost different things and ask different things of you.
| What you need | Open source script | Custom development | Yclas, hosted |
|---|---|---|---|
| Time to launch | Days to weeks of setup | Months | The same day |
| Upfront cost | Free or a licence, plus theme and plugins | A developer's quote, usually the largest cost | None: 15 days free |
| Hosting, updates, backups | You run them | You or your developer run them | Included |
| Split payments to sellers | A plugin, if one fits your gateway | Built for you | Stripe Connect on Marketplace |
| Transaction fee to the software | None | None | None |
| Changing the code | Anything you can code | Anything you pay for | Design, fields, custom code sections; no server access |
| Who fixes it when it breaks | You | Your developer, if still available | Our team |
| Monthly running cost | Hosting and your time | Hosting and maintenance | From $19, all included |
If your marketplace needs a workflow no builder has, custom development is the honest answer. We also build custom designs and features on Yclas: see Custom design.

Four ways a marketplace earns.
Commission is the classic model, but most young marketplaces start with listing upgrades and seller plans, which earn before the first online sale.
Prices are examples: you set your own, in your currency. Yclas takes no commission on what you earn. All the ways to make money →

Marketplace website builder FAQ
What is a marketplace website builder?
Software that gives you a ready marketplace site without writing code: seller accounts, listings, search, messages, payments and an admin to run it all. You choose the categories, design and rules, and the builder hosts and updates the site.
Is Yclas the right marketplace website builder for me?
It fits when sellers list items or services and buyers search and contact them, with online checkout added when the market wants it: second-hand, vehicles, equipment, rentals, local and niche trade. If you sell only your own stock, a store builder fits better. If your marketplace depends on a workflow nobody has built, look at custom development.
Does Yclas take a transaction fee?
No. You pay the plan price, from $19 a month, and keep your commission and fees. Stripe, PayPal and other providers charge their own payment fees.
Which plan do I need for a multi-vendor marketplace?
The Marketplace plan ($149 a month) for the cart across sellers, storefronts, escrow and your commission, with the Nova theme. Buy now with stock and orders starts on Professional.
How are sellers paid?
With Stripe Connect, each seller opens a Stripe payout account from your site and receives their share of each sale, at once or after the buyer confirms delivery. Without Connect, buyers pay you and sellers withdraw their balance, which you pay out by PayPal or bank transfer.
Can I start without online payments?
Yes, and many marketplaces should. Buyers and sellers agree on payment between them, and you earn from featured listings and seller plans. Switch on checkout later; nothing has to move.
Can I move an existing marketplace to Yclas?
Yes. Import listings and users from a spreadsheet or from Osclass, Flynax and WordPress plugins, with a dry run first. Redirects keep your old links working.
Is there a mobile app?
The site works like an app on every phone and can be added to the home screen, with push notifications. The Marketplace plan includes a branded iPhone app published under your name.
