Stock Receipt & Cost Tracking
When you approve or pay a purchase invoice, EVRST automatically:
-
Adds the received quantity to your stock
-
Updates the item cost based on what you actually paid (moving weighted-average costing)
-
Locks the purchase lines so you cannot change quantities (received goods are immutable)
This ensures your inventory and profit calculations are always accurate.
Fixing a Purchase Mistake
If you posted a purchase invoice by mistake:
-
Open the invoice
-
Click Void at the top
-
Choose whether to reverse the stock (return goods to vendor)
-
Add a reason for the audit trail
-
Confirm
The invoice is marked void, excluded from reports, but kept for record.
Frequently asked questions
Does recording a purchase invoice update my stock and costs?
Yes. When you approve or pay a purchase invoice, EVRST adds the received quantity to stock and updates the item cost based on what you actually paid, using moving weighted-average costing.
Can I change a purchase invoice after posting it?
No. EVRST locks the purchase lines once goods are received, so quantities cannot be changed. If you posted one by mistake, void it instead, choose whether to reverse the stock, and add a reason for the audit trail.
