The document discusses a transfer pricing (TP) documentation application that was designed based on Polish tax regulations, which are substantially aligned with OECD Guidelines. The application consists of three functional layers: a document management module for indexing, storing, structuring and versioning of TP documentation; an analytical module for financial data import and TP analysis through internal/external benchmarking and own/commercial databases; and a workflow collaboration module for task delegation and permission levels. The document management module also automates the creation of recurring and periodic TP documentation through documentation patterns and synchronization of changes.
