One of our clients is using an abomination of e-commerce called Satchmo.
The client has described the solution as "cumbersome", "difficult", "slow" and a few other words not suitable for print.
We've been assigned the task of re-vamping their solution.
Despite the odd database schema and lack of documentation we're confident that this can be re-worked into our PHP/Radix based solution in short order.
Check back in three weeks for details.
