Swap marketplace software for trading, not selling.

Yclas is swap marketplace software for barter websites and trade communities: people list what they have and what they want in return, talk it through in private messages and swap. Clothes, books, plants, games, tools or skills, with or without money involved.

For communities that trade.

Swapping needs one thing a sale does not: both sides have to want what the other has. The site's job is to make that match easy to find.

Haves and wants Every plan

Every listing says what it would swap for.

Add a "Wants in return" field to the form and make it searchable, so someone with a bike can find everyone who wants one. Add an "Open to cash" checkbox if part-swaps are allowed. Or switch the price field off altogether and keep the site cash-free.

  • Your own fields: size, condition, brand, "swap only" or "swap or sell".
  • Wanted category for people who only post what they are looking for.

Agreeing a swap Messaging add-on · offers in Settings

Trades are agreed in the chat.

Members message each other in one thread per listing, with photos of what they would offer. Where cash is part of a deal, the built-in offer lets one side propose an amount and the other accept, decline or counter. Offers expire after seven days.

  • Push and email notifications for every reply.
  • Follow traders whose things you like.

Ratings after every swap.

Both sides rate each other, and ratings show on the trader's page, so a reliable swapper stands out. Reports, banned words and AI checks keep out sellers who use a swap site to advertise.

  • Verified badge for traders who send an ID.
  • Safety tips in the chat for common scams.

Questions

Swap marketplace software FAQ

Part of:

Local buy & sell
What is swap marketplace software?

Software for a website where people trade items or skills with each other instead of selling them: listings say what is offered and what is wanted, and the two sides agree a swap in private messages.

Can the swap marketplace software work without money?

Yes. Switch the price field off and the site never shows a price. Messages are free.

Can I build a barter website with trade credits?

No. There is no barter currency or credit balance between members. Swaps are agreed directly between the two people.

Does it match trades automatically?

No. Members find matches by searching the "Wants in return" field and by saved searches with alerts.

Can services be swapped too?

Yes. Add a Skills category with fields such as hours offered and what is wanted in exchange.

Can members rate each other?

Yes. Reviews after a swap show on each trader's page.

Can I run swap events?

Yes. Events carry a date, a venue and repeats, appear on a calendar page and go out in the weekly digest.
