Key Features

account.move.line: Computes purchase cost from product standard price with unit and currency conversion and derives margin amounts/percentages, skipping purchase documents and handling refunds with signed margins.
security: Provides a “Show Invoice Margin” group to gate visibility of margin fields, enabled for the administrator by default.
technical: Pre-init hook creates missing margin-related database columns and backfills margins for existing invoices during installation or migration.
