I love ecomdash, and have invested hundreds of hours getting it setup, but once our subscription is up if the speed issues have not been fixed I will be forced to go somewhere else as it just completely kills productivity.

First of all, Ecomdash is the absolute best value out there if you sell on the marketplaces they cover. And I have evaluated 6-7 platforms in depth. That being said, it has some real shortcomings.
The Pros: Great Customer support, easy to use, efficient and logical back-end, clean user interface and it works without glitches.
Documentation is thorough and well-written.
If you are good with spreadsheets, ECD offers excellent capabilities to upload and download information. Really superior to all others in its range.
If you sell on Amazon, ebay and a website, ECD will work great and the price can't be beat. Go for it!

Cons: Useless reporting: you will have to get your facts and figures somewhere else, or link many many spreadsheets together. It's like a black box for sales information. They have about 40 different very narrowly-focused reports which are not flexible enough to answer more than one small question at a time, so you will have to download a million of them. They do offer to create custom reports, and that could help. Does not track Amazon FBA returns, last I checked, so if you're return rate is above 2-3%, you're just not going to be able to accurately track your sales through ECD.

Listing doesn't really work. Can't create ASINS in Amazon, so if you have brand-registry, forget it. Does not list variants to BigCommerce, last time I checked, and did not list variants in general, so if you deal in different sizes and colors, the listing facility may as well not exist. NOTE: Limited/Phony Listing capabilities is the norm for ALL programs that cost less than about $/yr upwards. But you need to ask the questions and not go in believing the bullet points on the landing page, then you can fit Ecomdash realistically into your workflow. The devil is in the details.
I tuned out after a few broken promises about integrations and updates, so they may have fixed some of these issues, but you MUST ask specific questions.

We switched to Linnworks, which has some of the same issues, because we needed a more European focus and because of the utter inadequacy of the ECD reporting module. All in all, though, Ecomdash is an excellent program and company in a very muddled field. Recommended.

For the money, this is good value. We recommend you have a strong vision for how you want your system set up and have prior experience using such a system. We don't get much value out of the listings upload capability to our multi channels. However, we don't want to spend our time manually reconciling inventory each day. This takes the worry out of it once it's set up. Be patient and eventually you'll be on auto-pilot. Do difficult or new work during business hours so you can chat or call for help.
