We found numerous flaws in the multi-vendor software that made no sense from an ecommerce perspective such as:
1. All forms that contain an address use a drop down field for the city which must be pre-programmed to contain the city of your customer. There is no way you can know which cities, out of the hundreds of thousands of cities in the world, that your customer lives in or will wants to ship to. Just ridiculous. When we brought it to their attention they wanted to charge us an exorbitant fee for "development" to fix it. Later we found out that they had already done the fix for an Australian site and wanted to charge us again for fixing something they had already fixed for another customer.
2. There is no way to delete products or coupons that you don't want to display on any of the sites. And no way to search for transactions by date or period of time such as by the day, by the week a certain month or certain time segment. You can only search by the customer's name or order number, one-order-at-a-time. Again, extra charge to fix.
3. No coupon field in the checkout page to be able to use coupons.
There are many more problems which they will be glad to fix for extra cost making the final bill at least twice their advertised price. Not enough room here to list them all.
Company refuses to use any kind of legitimate 3rd party escrow service to guarantee, after repeated delays in delivering software on time, an acceptable end product. Also many of the Gallery of sites they display on their website I found out are not real companies or merchants. They made them up for show in their gallery. Spending some time drilling down into each of the sites show pages to don't contain anything real and don't go anywhere. Fake companies and products.
