Yes, Positive Spin, the organization I am involved with, utilizes the Yellow Bike Database (YBDB) for all their shop openings. It is a fork of Austin Yellow Bike Project's original code that I have been continually developing since late 2014. Before that point I created several software demos of existing Community Bike Shop software to explore our options. I continue to maintain and add software demos so that other bike collectives can explore their options, and/or join in the process of developing Community Bike Shop and related software.

Our fork of YBDB has been especially successful for us because it is easy to use, configurable, versatile, tied into our policies, automates many tasks like keeping track of volunteer hours, which can be exchanged for our EAB/parts program via the same interface, exports transaction data from sales to our bookkeeping system (GnuCash), provides a simple CRM, and many other features as described at https://github.com/fspc/Yellow-Bike-Database/wiki/Features .

I was reading on the bikex website that you are the new General Manager (congratulations on your new role), and one goal being considered is opening up a Community Bike Shop. However, software-wise if you are looking at the current model that Silicon Valley Bicycle Exchange now utilizes, which involves repairing bikes and giving them to folks referenced by agencies and organizations, Recyclery Bikes and Clients Database would provide just such a software solution.

Inventory management: Along with the Recyclery Bikes and Clients Database, BikeShed provides this capability, Workstand recently added this functionality along with a serial number search at the Canadian Police database, BikeTree keeps track of rental bikes, YBDB keeps track of inventory with the Donation transaction type, and BikeBinder provides dedicated software specific to inventory management.

POS: YBDB, BikeTree, BikeShed and Broke Spoke's Shop Management System .. also the Bicycle Kitchen POS, but it is outdated.

Currently, the most active projects are the YBDB (fork), Workstand, and occasionally the Sign-in app.

Play with the demos, and feel free to submit feature requests to the respective projects.

I am happy to answer additional questions. The challenges of operating a smooth spinning and trued bike collective, have made me an expert in this area.
