Part-time clothing resellers on Vinted, Depop, and Etsy generate a steady stream of shipping labels and invoices across multiple platforms. These documents arrive as PDFs scattered across email inboxes, platform download folders, and printer queues, named with cryptic strings like label_8372.pdf. At tax time or during returns disputes, a reseller handling dozens of sales per week has no clean record and wastes hours hunting for the right document. DropPop for Vinted Resellers solves this by automatically renaming and filing shipping labels and invoices from Vinted, Depop, and Etsy sales into structured, predictable folders. The solution connects to the reseller's source of documents, detects the platform and order details, applies a consistent naming convention, and sorts everything into a logical folder hierarchy. The MVP is deliberately narrow: ingest PDF labels and invoices, extract order identifiers, rename to a clean template, and file into dated or platform-based folders synced to a cloud drive. Revenue comes from a low-friction monthly subscription aimed at the part-time reseller who values time savings but will not pay enterprise prices. Go-to-market starts inside reseller YouTube and community channels where organizing inventory and paperwork is already a recurring topic, as seen in the reseller filing and packaging storage content. Growth loops form as resellers share their tidy folder systems and recommend the tool in Depop and Vinted seller groups, where process tips spread quickly. The named competitor DropPop proves a paying audience exists for exactly this document organization workflow.
