Poor basic system, with poor customer service. Had its day.
I decided to use ekm to grow my off-marketplace business. Initially I thought it to be a reasonable system, easy to start using etc. However its when I really needed it to do certain e-commerce standard things that it fell down. At the time, the API was not opened up, so I could not control it with my inventory management software, thus meaning I had to manually adjust (definitely unacceptable).
They charge for the web stats (£5 a month ) from memory - and what a let down. To say its basic was an understatement.
Not that this affected me as I am vat registered, but price was advertised as £19.99 a month, but was + vat (annoying for companies who are under the vat threshold).
When I closed the account, I had pre-paid until the end of the month, but they just shut it down altogether, with no access to customer orders (this was not explained). When I asked for access, they said I would have to pay again. Their mood/attitude towards me once I cancelled was of utter contempt.
I asked for a code to transfer my URL, and I got this ok, but a few months after I noticed they had again charged me for hosting the URL. I had to call them and request this to be refunded.
I don't trust they are able to competently provided a positive customer experience (especially if you ask them to close it down). The system is ok for people playing at ecommerce, and if all their inventory is just located there....but at that price there are MUCH better systems out there - such as Big Commerce; epages.
