How to manage vendors and materials, raise purchase orders, walk them from open to received and paid, and how each step posts journal entries to your books automatically.
The Supply Chain page (coach/branch admin only) is where you manage everything you buy: the vendors you order from, the materials you stock, and the purchase orders that bring gear and services into your gym.
It sits alongside Inventory and Accounting and ties them together. When you receive a purchase order, the stock lands in Inventory; when each step is completed, the matching entries are posted to your Accounting ledger automatically. You never touch a spreadsheet.
The page has three building blocks:

In the right-hand column, fill in the Create vendor form:
Click Create vendor. The vendor appears in the list below; click any vendor to see its full contact card. Vendors are reused across every purchase order, so you only enter each supplier once.
A purchase order's goods lines reference a material. Gear items you already sell are available automatically; for anything else, add it under Manual materials:
Click Create material. Manually-created "other" materials can be deleted later (gear-backed materials cannot). Materials are what you pick from when adding goods lines to an order.
Use the Create purchase order form:
The new order shows up at the top of the Purchase orders table with status Open, priced in your branch's billing currency.
Select a purchase order to open its detail panel. Depending on the current status, the action buttons walk it through the workflow:
Each transition is one click, and you can follow the inventory and accounting links on each line to see exactly what was created.
This is what makes Supply Chain more than a shopping list: CompTeam keeps your books in sync without any manual bookkeeping.
As an order moves through its lifecycle, the right double-entry journal entries are posted for you:
In the order detail, once an order is received and paid, each goods line shows Inventory and Receipt journal links, and the order footer shows the Payment journal reference. Click any of them to jump straight to the exact entry in Accounting → Entries. Nothing is posted twice, and the order's status always matches what's in your ledger.
