Receipt Vault Organizer turns a messy NAS folder of scanned receipts and invoices into a searchable, per-company expense register with the originals filed by year and month. Built for owners of one to three micro-businesses who photograph every receipt but file almost none. The Skill watches one authorized inbox folder on a UGREEN AI NAS, reads each document locally (ug-document extract, ug-photo vision-ocr), extracts vendor, date, total and tax, proposes a company and category, and — only after the user confirms the list — files the original (ug-filesystem, file-workflow batch-move, ug-filemgr tags), appends a register row (ug-knowledge save-text), and reconciles the totals (ug-document reconcile). Unreadable documents go to a Needs Review folder, never guessed or discarded. Documents never leave the NAS: no subscription, no third-party cloud. The Round 1 package was validated with the official UGREEN checker (static pass) against the Skill Developer Package capability catalog 2.2.0.
