Costing method, when cost of goods sold is recognised, and how adjustments post.
The costing method is set per workspace and applies to valuation and to cost of goods sold. Changing it after transactions exist changes the value of stock on hand, so it is treated as a controlled change rather than a setting.
Stock adjustments post a document like any other movement. A count difference is not a silent correction — it is an entry with a reason, which is what an auditor will ask for.
Create a workspace, import a chart of accounts and post a document. The ledger underneath is the same one that will carry you at ten times the size.
