This is for Xero only.
Zigaflow enables you to increase your stock value upon receiving supplier invoices (SIs) and then transfer this value to COGS when the items are dispatched.
Set these in the Cog -> Financial Settings -> Defaults:
If these codes are not available in the dropdowns, use the 'Account Codes' panel just below to import them from your account software.
Once they are set up, the user has a choice when a supplier invoice is entered into the system - either set it to COGS immediately, or to your Stock Nominal Account (SNA). If this is for stock items, the purchase account code should be set to your SNA. Note that the value in Xero is only updated when the supplier invoice is exported to it.
If you have set up your nominal codes similar to the screenshot above, when the items are delivered/booked out of inventory/stock, the SNA is credited and the COGS is debited.
