Chambers of Commerce
The typical product Social TRade offers a Chamber of Commerce is the implementation of a C3 circuit (network). The Chamber can use that circuit not only as a tool to stimulate local mutual trade, but also as a source for cheaper credit for their members, and as a way to make a collective effort to capture more of the available purchasing power within the community or region.
For example the C3 Compras in Porto Alegre delivers immediate purchasing power for shops that have accepted pre-dated cheques from their trusted customers.
Gapgiroweb is a C3 model for the more advanced businesses, which allows businesses to improve their liquidity - provides credit against just a little more than the cost of a credit insurance.
The BarterC3 PuntoTRANSacciones established by the Salvadoranian organisation FUSAI demonstrates the options for mutual Barter between the members of a Chamber.
