Make products, sell them, and manage everything in between
Track raw materials, manage product assemblies and bundles, handle purchasing and inventory, and sell finished goods through your own storefront or wholesale channels.
Sound familiar?
Making great products is only half the battle
You know how to make things. But managing materials, inventory, orders, and sales across disconnected tools is slowing you down.
Materials and inventory don't connect
Raw materials are tracked in one system, finished goods in another. You don't know what you can actually sell until someone checks the warehouse.
Selling is an afterthought
You're great at production but your sales tools are basic. No proper webshop, no wholesale portal, and orders still come in by email.
No visibility across the operation
Purchasing, inventory, production, and sales all live in separate spreadsheets. Getting a clear picture of your business takes hours of manual work.
