The big difference between MLM and a pyramid scheme is in the business' operations. The entire purpose of a pyramid scheme is to get your money and then use you to recruit other suckers (ahem - distributors). The entire purpose of MLM is to move product. The theory behind MLM is that the larger the network of distributors, the more product the business will be able to sell.

Use these questions as an acid test if you're in the least doubt as to whether the opportunity you're considering is MLM or a pyramid scheme:

1) Are you required to "invest" a large amount of money up front to become a distributor? This investment request may be disguised as an inventory charge. Legitimate MLM businesses do NOT require large start up costs.

2) If you do have to pay for inventory, will the company buy back unsold inventory? Legitimate MLM companies will offer and stick to inventory buy-backs for at least 80% of what you paid.

3) Is there any mention of or attention paid to a market for the product or service? MLM depends on establishing a market for the company's products. If the company doesn't seem to have any interest in the consumer demand for its products, don't sign up.

4) Is there more emphasis on recruitment than on selling the product or service? Remember, the difference between MLM and a pyramid scheme is in the focus. The pyramid scheme focuses on fast profits from signing people up and getting their money. If recruitment seems to be the focus of the plan, run. These next two questions will help you determine what the focus of the company is:

5) Is the plan designed so that you make more money by recruiting new members rather than through sales that you make yourself?

6) Are you offered commissions for recruiting new members?

As always, when you're investigating a potential business opportunity, you'll want to gather all the information you can about the MLM company's products and operations.

Get (and read) written copies of the company's sales literature, business plan and/or marketing plan. Talk to other people who have experience with the MLM company and the products, to determine whether the products are actually being sold and if they are of high quality. Check with the Better Business Bureau to see if there have been any complaints about the company. And listen carefully when you're at that MLM recruitment meeting. Inflated claims for the amazing amounts of money you're going to make should set your alarm bells ringing.

Being part of a successful MLM company can be both profitable and fun, but unfortunately, some purported MLM opportunities are actually pyramid schemes designed to flatten both your wallet and your dream of running a business.
