How Fiddle is organized

Fiddle is built around a few core modules that share one source of truth for your stock. Knowing how they fit together makes the rest of the Help Center easier to follow.

The core modules

Module	What it handles
Inventory	Items, variants, lots/serials, locations, stock levels
Purchasing	Suppliers and purchase orders that bring stock in
Sales	Customers, quotes, and sales orders that send stock out
Production	BOMs and work orders that turn components into finished goods
Fulfillment	Pick, pack, and ship for outbound orders
Reports	Stock, sales, purchasing, and production insights

How the pieces connect

Everything centers on the item. A purchase order raises an item’s incoming stock; receiving turns it into on hand. A sales order reserves on-hand stock, then fulfillment ships it. A work order consumes components and produces finished goods — all updating the same item records in real time.

Because all modules read and write the same stock figures, an action in one place (like issuing a PO) immediately affects numbers everywhere else.

Settings tie it together

Settings is where you configure locations, units, users, and integrations that the other modules rely on. Set these up early so your data lands in the right place.
