I am a senior software engineer responsible for implementing ERPNext for a company that operates several businesses. They currently run Quickbooks and ACT! which are not designed for the volume of business they have.
This will be a very complex implementation. To give you an idea of how complex, an official Odoo partner failed to deliver an workable implementation of Odoo here a few months back. An example requirement: two of the companies pull from a common inventory (same product sold as different UPCs).
I am going to need help because of time constraints. You would be assigned discrete tasks from the implementation timeline and expected to estimate time-to-complete and implement within your estimates. Pay would be hourly & negotiated with the company directly.
