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 of the software, we switched to exclusively using SixBit for auctions and post sale processing. It’s the type of software that has been so skillfully designed, that when you wish it included an option to do “X” … you find out that it already has that option. It is a very intuitive program, and once you get the templates, and listings pages just right… you’re off to the races. It is very easy to bulk edit, reschedule, and modify everything. Finally, when we get stuck on something, their technical support is REAL technical support. You don’t get the run-around like “we’ll talk to our development team, and get back to you…” – you get REAL people like Steve or Dustin that assess the problem and fix it, in a cordial and courteous manner. I actually turn to my wife and ask … “Have I told you how much I love SixBit?” at least once a day.

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've used SixBit since Blackthorne was discontinued and I absolutely love it. Their system is very easy to use. They created this software from the seller's point of view. Their technical support is awesome and they are there right away when you need them. Excellent service for an excellent eBay and Amazon listing tool.

I'll recommend this software to any seller I know. Great job and keep up the good work!

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!!"
