Question: Where do i enter my opening stock to deduct against this years sales?

Answer:For Company Tax Return (CTR), please record via "Financial Information"

Question: Also are b/fwd losses automatically utilized or do i need to decide how much to use?

Answer: If this is an accounting import, make sure to create a journal entry to record Opening Balance plus Purchases minus Closing Balance as Cost of Goods Sold in your books. Once done, you have to import in LodgeiT and check on the mapping and should automatically show here

If you want to do CTR manually, you have to fill these up.

Cost of sales will show up as an Direct expense and should be injected if Financials where imported or manually filled in on A-Cost of sales
