StickerCalc is a premium mobile software-as-a-service (SaaS) application designed to streamline retail transactions in fast-paced environments like markets and fairs. Available on both iOS and Android, it functions as a lightweight point-of-sale (POS) tool that simplifies checkout processes, tax calculations, and accounting, offering significant advantages by being an offline-first utility. This design means it incurs a permanent $0 per month infrastructure cost, with all transaction calculations handled locally on users' devices. The application is currently sold pre-revenue by its founder, who seeks a growth marketer for wider distribution. Key features include a zero-cost scale architecture, advanced local engine functionalities like real-time price adjustments, and a comprehensive multi-vendor tracking system that caters to different user needs. Additionally, the app supports dynamic updates through a catalog file fetched from a public repository, negating the need for app store approval for each update. Potential buyers are offered an exclusive first right of refusal for a companion app called BeamMe, which could further enhance a retail ecosystem by offering a secure peer-to-peer payment solution. The sale process is conducted through an asynchronous, text-based due diligence protocol to accommodate development schedules, with comprehensive resources like video walkthroughs, codebase access, and detailed documentation available to serious buyers. All inquiries and negotiations are handled via a designated platform chat to ensure a smooth transaction.
