Delivery from Sales Invoice
If you have items delivery and invoicing happening at the same time, you can create delivery with Sales Invoice itself. Sales Invoice has a field called Update Stock, just before the Item table. If this field is checked, on submission of Sales Invoice, stock of Item will be deducted from selected Warehouse.
On checking Update Stock, Sales Invoice Item will show relevant fields like Warehouse, Serial No., Batch No., Item valuation etc.
On submission of Sales Invoice, with general ledger posting, stock ledger posting will happen as well.
