How do you manage inventory across multiple channels?

How does everyone manage their inventory across multiple channels?

Most successful eretailers offer their products through multiple channels (eBay, Amazon, websites, etc. not to mention all the shopping/search engines).

For us, we use a simple excel file that contains the necessary values for each product according to each channel and then manually upload it to each respected channel. Ahhh! Not to mention, we need to add all the product information to our accouting software and other backend software.

Finding a simple typo can mean an hours worth of work. Go find it in eBay, revise it. Go find it in Amazon, revise it. Go find it on our websites, revise it. And the list goes on…

Is there a better way? The closest thing I’ve found is Channel Advisor but the thought of giving away 1-2% is scary.
