BizX members should be selling their products and services at 100% BizX. After all, that's why you joined, right? There are a few exceptions to this rule and the most important thing to note is that BizX Senior Management must approve in advance any cash/BizX blended transactions. Some circumstances where this might be approved include a single, large transaction; if the seller has to out-source some of the services; if parts or equipment needs to be special ordered; or finally, if it is an extremely low-margin item. These are decisions made very thoughtfully between management and the BizX member. If you have a question about a bid or quote that includes cash, send an email to Our team will investigate it and let you know how we've handled it. Gratuity at restaurants should always be paid in cash at the standard gratuity rate of 15-18%.
