RedAnt records all stock movements using Goods In Records (GRNs) and Goods Out Records (GONs). Stock balances are calculated from these transactions, and stock adjustments create additional Goods In or Goods Out records rather than replacing existing quantities.
Important: Stock adjustments are incremental. Always enter the quantity to be added or removed, not the final stock quantity you want to see.
New Balance = Existing Balance + Adjustment
Example
If you entered 110 as the adjustment, the balance would become 210.
Use an opening balance when recording stock that already exists physically and has not yet been entered into RedAnt.
RedAnt creates a Goods In Record (GRN) for the quantity entered.
Example
| Starting Balance | Adjustment Entered | Result |
|---|---|---|
| 0 | 100 | Goods In of 100 created; balance becomes 100 |
If stock already exists, the quantity entered is added to the current balance. It does not reset the balance.
Use a stock adjustment when the recorded quantity differs from the physical stock count.
Adjustment = Correct Quantity − Existing Quantity
This preserves a complete stock transaction history and audit trail.
| Existing Quantity | Correct Quantity | Adjustment to Enter | Result |
|---|---|---|---|
| 0 | 100 | 100 | Opening Goods In of 100; balance becomes 100 |
| 100 | 110 | 10 | Goods In of 10; balance becomes 110 |
| 100 | 92 | -8 | Goods Out of 8; balance becomes 92 |
| 25 | 0 | -25 | Goods Out of 25; balance becomes 0 |
The Free Stock value displayed on the Stock screen shows the quantity available for allocation or issue after considering stock already allocated to job orders.
Because of this, Free Stock may be lower than the overall stock balance even when no stock is missing.
| Measure | Quantity |
|---|---|
| Stock Balance | 100 |
| Allocated to Job Orders | 30 |
| Free Stock | 70 |
In this example:
| Situation | Free Stock |
|---|---|
| 100 units held, 30 allocated to job orders | 70 |
| A further 10 units added, allocations unchanged | 80 |
| A further 5 units allocated to a job order | 75 |
Use the Allocations button on the Stock screen to review stock issued to jobs that are not yet complete.
A green Allocations button indicates that active allocations exist for the selected item.
Stock allocated to a job order may still be physically present in the warehouse while no longer being available for other work.
