The problem
Jewelry manufacturing and wholesale runs on inventory, vendors, artisans, purchase orders, work orders, QC, shipping, invoicing, sales, and accounting — and in most shops, on a dozen spreadsheets and a group chat.
Generic ERP doesn't model the parts that matter here: a work order that passes through an artisan, metal and stone costs that move, QC before a piece can ship.
What I built
One system covering the operation end to end — inventory, purchase orders, vendors, artisans, work orders, quality control, shipping, customers, sales, invoices, accounting, and reporting.
With agent concepts layered over the repetitive edges: a vendor agent, an order agent, and an invoicing agent for the work that is mechanical but still eats a day a week.
Selected details
- Grounding
Built against real jewelry and e-commerce operations — fine jewelry in 14k and 18k gold and 925 silver, with custom manufacturing workflows — rather than as a portfolio ERP with invented requirements.
What I took from it
- Vertical software lives or dies on whether it models the exceptions. The happy path is the easy half.
