[TheThinkTank] point of sale / inventory management

Hey friends,

The Silicon Valley Bicycle Exchange is considering a point of sale system for some used bike and part sales, and perhaps some new accessories. Inventory management would be helpful. I know Lightspeed https://www.lightspeedhq.com/ is a very popular solution, but I'm curious to learn what other solutions other community shops use and can recommend?

Thanks in advance.
