I almost quit eBay, then I found SIXBIT

I have been selling on eBay for over 22 years. All this time I have been reinventing my business to keep abreast of the constant changes eBay was introducing. Some of these changes were good for my business, but most just made it harder for me to sell. I just wanted to quit eBay. But some of my vast collection really only sold well on eBay, some items would only sell on eBay. I needed to find a solution that would bring me back to seller heaven, or figure out other ways to liquidate my special stuff, or just quit.

Your software is fantastic. Way better than Turbo Lister. You guys need to advertise more!! SixBit is much faster than Turbo Lister. It is not only faster in uploading your listings to eBay, but it is faster to use. It is like they took all of the little annoying problems of Turbo Lister and fixed them.

I have been using SixBit since it was released after eBay Blackthorne became unsupported and at first we were a bit iffy on switching but it seemed to be the best option…..SOOOOOOOOOOO glad we did. The program is great and if there are any issues, the staff, both through tickets and on the phone are great and supportive in figuring things out. We give a big shout out to the guys and gals at SixBit and we are looking forward to many more years of working with them!!! You won’t be sorry!!

Not sure where to start, but we’ll begin with a huge thank you to John Slocum and his staff. Moving to SixBit has improved our workflow infinitely. Lisa and I sell postage stamps and we list about 50,000 auctions on eBay each year, along with keeping about 6,000 Buy-It-Nows in our store. We had been having issues with our previous lister and decided to try SixBit. We gave SixBit a try and were not only impressed by its ease of use, but also by the customer/technical support that goes with it. Within a couple of days, after learning the ins-and-outs
