The reason most businesses join bartercard is to increase their sales. Isn’t that what everyone wants? it’s why we go networking, why we advertise and its generally the reason we went into business in the first place – because we thought we could earn more (by selling more) than working for someone else.
When you barter using bartercard you swap your services at their full value, there are many discount schemes now being promoted, they generally get you to heavily discount your product/service and charge you a fee on top. The theory being that the new clients who use the discount scheme will want to come back and pay full price, it could work, but I suspect many people just take the special offers.
Bartercard now have 75,000 worldwide members, so there are plenty of businesses to swap with and Bartercard give a guarantee that they will get sales for your business. So if you want more sales, why not give it a go?
