For most small business that deal in physical goods, a large part of their net worth is invested in the stock in hand.
|
|||
|
|
|
|||
|
|
### Best Practice
|
|||
|
|
|
|||
|
|
There are two aspects to good material management:
|
|||
|
|
|
|||
|
|
- **Good housekeeping / visual control:** Keep all your items in separate bins and each neatly stacked and labelled.
“A place for everything and everything in its place”
|
|||
|
|
- **Accurate Data:** Accurate data comes from good processes and recording each and every transaction. If you are only partially recording your inventory then your reports will be incorrect
“Garbage In Garbage Out”
|
|||
|
|
|
|||
|
|
If you have good processes to control movement of goods within your organization, implementation in ERPNext will be a breeze.
|
|||
|
|
|
|||
|
|
### Material Flow
|
|||
|
|
|
|||
|
|
There are three main types of entries:
|
|||
|
|
|
|||
|
|
- Purchase Receipt: Items received from Suppliers against Purchase Orders.
|
|||
|
|
- Stock Entry: Items transferred from one Warehouse to another.
|
|||
|
|
- Delivery Note: Items shipped to Customers.
|
|||
|
|
|
|||
|
|
#### How does ERPNext track stock movement / levels?
|
|||
|
|
|
|||
|
|
Tracking stock is not just about adding and subtracting quantities. Some complications arise when:
|
|||
|
|
|
|||
|
|
- Back-dated (past) entries are made / edited: This affects future stock levels and may lead to negative stock.
|
|||
|
|
- Stock has to be valued based on First-in-First-out: ERPNext needs to maintain a sequence of all transactions to know the exact value of your Items.
|
|||
|
|
- Stock reports are required at any point in time in the past: You have to lookup what was the quantity / value your stock of Item X on date Y.
|
|||
|
|
|
|||
|
|
To manage this, ERPNext collects all inventory transactions in a table called the Stock Ledger Entry. All Purchase Receipts, Stock Entries and Delivery Notes update this table.
