Who we are

The Platforms

The Community Exchange System (CES) started as an experimental online LETS in Cape Town, South Africa, in 2002. In 2003 it was launched as the  first mutual credit platform on the internet. CES pioneered inter-trading between communities when exchange groups in other countries joined, creating the first global, alternative exchange network. These different systems link through ‘Clearing Central’, a bridging facility created by CES. In 2008 CES registered as a not-for-profit organisation.


Community Forge’ was a platform formed in 2009 to provide software tools for communities and soon partnered a cluster of Belgian LETS who helped with testing and specifying software. In 2010 they published their software distribution. In 2011 they built a custom sitefor Route des SEL, a hou se sharing network for SEListes. In 2012, there was enough need and interest to start a support team which manages all technical matters day-to-day. Community Forge now hosts well over 200 active groups, runs software training workshops, helps organise the LETS summer camp in France. The community is funded only by donations.

CES Australia hosts 20 active LETS in Australia. It is run by an unincorporated, volunteer-run organisation, using a clone of the original CES. CES Australia is focussed on building awareness of community exchange, promoting best practice, supporting group administrators, and redeveloping the online trading platform. CES Australia is supported by a 1% levy on transactions and donations from trading groups.
