Additionally a Seller can mark an item as Shipped, and similarly a Buyer can mark an item as Received.
The DApp User Interface when running should look like...

A step by step series of examples that tell you have to get a development env running
Clone this repository:
git clone https://github.com/rafarodra/SupplyChainProject-Udacity/tree/SupplyChainProject-Udacity
Change directory to myCoffeeSupplyChain folder and install all requisite npm packages (as listed in package.json):
cd myCoffeeSupplyChain
npm install
Launch Ganache:
You can use the cli or the graphic client
Your terminal should look something like this:
In a separate terminal window, Compile smart contracts:
truffle compile
Your terminal should look something like this:
This will create the smart contract artifacts in folder build\contracts.
Migrate smart contracts to the locally running blockchain, ganache:
truffle migrate
Your terminal should look something like this:
Test smart contracts:
truffle test
All 10 tests should pass.
In a separate terminal window, launch the DApp:
npm run dev
