Most small shop owners never get a proper ERP. The software costs too much, and setting it up usually means hiring a consultant who understands module lists and hundreds of switches.
We built Mosaic ERP to change that. It's free and open source (MIT). Instead of a settings maze, it asks the owner plain questions: do you keep stock, do you buy from suppliers on credit, how does a normal sale work, which currency. Then it sets up the working ERP from the answers, and the owner reviews every change before it's saved.
Mosaic Shop Intelligence v2.1.8 by Hearthplug (formerly Mosaic ERP) is a free, open-source, AI-first retail ERP configured by an owner interview - hosted in the browser or self-hosted. v2.1.8 adds printable receipts, stock history with recount, a first-sale guide, chat-built dashboards, and stock intake from supplier bills. Built-in chat assistant by default. Before Apply, the review lists what's on and left off, in plain language. Books exports PDF/XLSX
