Use this screen to record a supplier's credit note when received. By doing this you will be able to return to the costings screen and compare estimated costs with actual costs. You can also run costings reports. The procedure is very similar to recording purchase invoices.
1. Open the Customer List and go to the Purchase Orders tab or open Projects > Purchase Orders.
2. Right-click on the P/O Ref and select Purchase Invoice:
2. Enter the supplier's credit note number in the box at the top right:
3. Enter the Nett amount and select the VAT rate and click Calculate. The full total will appear in the Total and the Unallocated boxes.
4. Tick the Allocate tick box next to a product and the estimated column is completed with the same estimated price. Change this price if needed to the value on the credit note. Then add a Qty in the column to the left, to confirm that this product is being credited:
In the above example product 1 has had a supplier invoice recorded for the same as the estimated price (£493.86) which is completed in the 2 green columns. The user is recording a £100 credit note against that product so has adjusted the 2 columns circled in red.
As you repeat and allocate amounts to different products you will see the Unallocated Total decreasing.
If the credit note applies to multiple products you should repeat until all of the credit value has been allocated.
Allocate the credit value proportionally across all products
4. If the credit note is for the complete order you can use the Auto Allocate button to evenly distribute the value across all products. This is a quicker way to record an invoice but it does not accurately record costs to a particular product, just the whole order.
5. Tick the Update Actual Costs box if you want to record the actual cost price (this is the actual price that appears in the costings screen and in reports). If you have only recorded an invoice for a quantity of 2 out of 4, you may wish to untick this, so that the costs do not look disproportionate against the total value. When you have recorded all 4 you could then tick the box.
Once you have seen the totals appear on each product line then you must also enter the Qty into the green column.
6. Click 
Update to save and close the window.
