Inventory

The Inventory module tracks the physical equipment your ISP buys, stores, and hands out to customers — routers, ONUs, set-top boxes, cables, and anything else you keep in stock. It records what you have, where it is, what condition it's in, and who is holding it, and it ties equipment that you sell or rent to a customer straight into billing.

The two building blocks: Products and Items

Almost everything in this module comes back to two ideas. Getting them straight makes the rest simple.

Term	What it is	Example
Product	A type of equipment — one catalogue entry (like an SKU). It has a name, a sell price, a rent price, an optional vendor, and a photo. There is one Product record per type.	"RB 950 Router"
Item	A single physical unit of a Product — one actual box on your shelf. Each Item has its own barcode, serial number, cost, condition, location, and a status saying where it is right now.	The specific RB 950 with serial A1B2C3

A Product can have many Items. When the Products list shows "In Stock: 12" against a product, that simply means 12 of its Items are currently sitting in stock.

Item statuses

Every Item is always in exactly one of these six states. You'll see these same colour-coded badges on the Items list, the dashboard chart, the reports, and each item's history:

Status	Meaning
In Stock	Available on the shelf, not yet given out.
Internal Usage	Being used by a staff member (not a customer).
Rented	Rented to a subscriber — links to the subscriber and a rental invoice.
Sold	Sold to a subscriber — links to the subscriber and a sale invoice.
Assigned	Handed to a subscriber at no charge (no invoice).
Returned	Returned — either back into stock or back to the supplier.

Each Item also carries a condition mark — New, Used, or Broken.

What's in this module

The Inventory menu follows this order:

Section	What it's for
Dashboard	A summary of your stock — totals, in-stock value, and a status breakdown chart.
Items	Every physical unit, and all the actions you take on them — sell, rent, assign, return, and more.
Products	The catalogue of product types, their prices, and their units.
Suppliers	The businesses you buy stock from.
Vendors	The brands/manufacturers you tag products with.
Supplier Invoices	Record stock received from a supplier — this is how new stock enters the system.
Adjust Stock	Correct a product's in-stock quantity downward (write-offs, losses).
Requisitions	Internal requests for stock, with an approval workflow.
Reports	Sold & rented items, and a full item history trail.

How stock flows

Supplier Invoice (goods in)  ──▶  Items created as "In Stock"
                                        │

• New stock enters by recording a supplier invoice (or by adding items directly).
• Stock leaves by being sold, rented, assigned, or moved to internal usage.
• Return brings a unit back into stock or sends it back to the supplier.

Who can use this module

Inventory / warehouse staff and their managers. Every screen and action is permission-controlled — depending on your role you may not see certain buttons (Add, Delete, Approve, or specific item actions like Sell or Rent).
