    We checked in with a couple of third-party service providers to see if they were safe from changes coming as a result of the Seller Update policies around selling tools.

    John Slocum of SixBit Software said the announcement doesn't affect SixBit users, and said his tool is a viable option for Turbo Lister users since it's a desktop application.

    Slocum said SixBit 3.0 is the company's first version with Amazon support, "so it is a pretty big step for us," he said.

    Way back in 1997, John Slocum created the very first software tool for eBay sellers: AuctionAssistant.

    Over the past twenty years John has not wavered from his niche of creating desktop-based, feature-rich software for eBay sellers.

    After eBay bought his first company in 1999, John spent ten years writing software as an eBay employee. When eBay let John and his team go in 2009, John set up his own company again and carried on writing software for eBay sellers.

    SixBit, which helps online sellers list on eBay and auction site BidStart, will launch support for Amazon on Monday and is working on supporting the Etsy marketplace as well.

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!

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.

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!!"
