Barter-based economies are one of the earliest, predating monetary systems and even recorded history. People can successfully use barter in many almost any field. Informally, people often participate in barter and other reciprocal systems without really ever thinking about it as such -- for example, providing web design or tech support for a farmer or baker and receiving vegetables or baked goods in return. Strictly Internet-based exchanges are common as well, for example exchanging content creation for research.
Search for bartering partners. After you know what you have to offer and exactly what you need/want in a barter situation, find a bartering partner. If you don't have a specific person or business in mind, try word of mouth. Let your friends, colleagues and social network know about your specific need and what you want in a barter situation. Use Facebook, LinkedIn and Twitter.
Corporate barter focuses on larger transactions, which is different from a traditional, retail oriented barter exchange. Corporate barter exchanges typically use media and advertising as leverage for their larger transactions. It entails the use of a currency unit called a "trade-credit". The trade-credit must not only be known and guaranteed, but also be valued in an amount the media and advertising could have been purchased for had the "client" bought it themselves (contract to eliminate ambiguity and risk).
The first 23 Barter Babes to join were friends and former PH&N co-workers who wanted to support Simmons. They mostly traded items and services to help out with the launch party: a lot of food, a press release, coat racks, silent auction items, courier services and social media consulting. Barter Babe No. 24, Grace Poon, was the first person to sign up for the project with whom Simmons had no prior connection. In exchange for Simmons’s financial advice, Poon provided graphic designs for an investment presentation (which Simmons still uses today). She remembers being excited, but also nervous: it was the first trade she’d made with someone who didn’t feel obligated to give her unconditional support. She needn’t have worried.
Debts in the wir currency, assigned the same value as the Swiss franc, could be paid with sales to any member of the bartering circle: if a baker needed to “purchase” eggs and flour from a farmer, the baker could pay off the debt by “selling” baked goods to another wir member. The farmer, in turn, could use his newly acquired credit to “buy” his own needed items or services. Despite a bank-led campaign to discredit the system, wir stuck. Today, it has more than 60,000 business participants and does the equivalent of about $4.4 billion in annual trade.
