I'm not a software guy. I built an ERP anyway.
Since 2022 my shop has run on four different ERPs. The first one we outgrew. The second was a full enterprise suite that took five months and a pile of money to not work. The third was an industry package that did most of what we needed and none of it the way we actually work.
The fourth one I built. Not from scratch, and not by writing code. I took Odoo, sat down with AI, and configured, customized, and connected it until it matched how a print and embroidery shop really moves an order from inbox to shipping dock.
I can't explain how most of the code works. I didn't write it. What I do know is my business, well enough to know exactly how the software should behave. That turned out to be the part that mattered.
I wrote the whole story up as a book, Stop Working for Your Software. And for the part of me that still has opinions about the first three systems, there's ERP Hell.
