We’re SixBit Software


SixBit Software was founded with the idea to help sellers build their eCommerce business from the ground up.

Check out what our customers have to say about us!

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.
