There are many people in today's market that label themselves "e-commerce companies." Here are some pointers to help you determine whether they offer legitimate ecommerce website development services or just a one-man show posing as an e-commerce company.
The most crucial factor is look. Take a peek at their own website for more information. Make your own judgement; if the company's website appears to be a template, this is a NO, NO.
A phone number is provided. If they don't have a phone number on their own website, run. I've observed some people who don't seem to care whether or not the company has a phone number. This is without a doubt the most prevalent blunder.
Cart (shopping cart). This is a little more technical; you'll need to know whether the company uses an open source shopping cart or a custom-built one. It's a little difficult to figure out. However, here are a few pointers.
The company places restrictions on your purchasing basket.
You can only upload one or a few product photos at a time.
Request that they demonstrate their work to you. Take your time with this and pay attention to the salesperson because he or she will almost always make a mistake.
Inquire about the length of time they've been in business.
The most crucial. Go with your intuition; if you're even somewhat hesitant, DON'T DO IT!!! Look for someone else.
