1. Know what you're selling Know exactly what you're selling before you start marketing it. You'll want to know if you're selling a product, service, or something else entirely. If you don't know what you're selling, then how do you expect someone to buy it? 2. Be clear about who's buying it If you're selling anything, make sure that people understand what they're getting. A lot of times, people think that they're buying a product, but they actually end up paying for a service. Make sure that you clearly explain what they're getting and what they need to do to get it. 3. Have a price point You should have a price point for everything that you sell. If you don't have a price point, then how do you know whether or not you're making any money? 4. Tell them where to find it People might think that they're going to buy something online, but they may end up having to go somewhere to get it. Make sure that you tell them where they can find it. 5. Don't oversell Don't try to sell something that you don't really believe in. People will sense it immediately and won't trust you. 6. Always ask for payment upfront Always ask for payment upfront. When you receive payment, you can give them their product or whatever else you sold them. 7. Never take payments via check Never take payments via check. There are many reasons why this isn't a good idea. First off, you could lose your money. Second, you could be charged fees. Third, you could even be held liable for fraud.
