About

JobProof TG is a transferable white-label field-service evidence product for small service businesses and agencies. A manager assigns a job; the technician accepts it in Telegram, checks in, optionally shares device-reported location, captures before-and-after photos, completes a required checklist, records notes, materials and issues, and requests customer acknowledgment. The system then creates a branded, immutable PDF report with a SHA-256 integrity value and an expiring, revocable share link.WHO IT IS FORCleaning companies, repair crews, installers, plumbers, electricians, appliance technicians, mobile detailers, property managers, maintenance teams, and agencies that want a reusable white-label solution.CORE FEATURES• Owner, Manager and Technician roles with assignment-level isolation• Strict, resumable job state machine and stale-write protection• Required checklist items saved as a per-job snapshot• Safe JPEG, PNG and WebP validation, re-encoding, thumbnails and SHA-256 provenance• Optional consent-based location with device-reported accuracy• Typed customer acknowledgment with an explicit legal disclaimer• Immutable PDF report revisions• Expiring and revocable report links with hashed tokens• Audit log, synthetic seed data and resettable browser demo• English default interface with a Russian localization foundation• Centralized white-label configurationTECH STACKPython 3.12, FastAPI, SQLAlchemy 2, Alembic, aiogram 3, PostgreSQL/SQLite, React 19, TypeScript, Vite and Docker Compose. No paid AI API is required.WHAT IS INCLUDEDApplication source code, database migration, automated tests, Docker configuration, browser demo, synthetic sample data, sample PDF, eight sale images, a short demo video, deployment/security/privacy/backup documentation, buyer handoff guides and white-label listing materials.HONEST STATUSThis is a new pre-revenue software asset. It has no real customers, users, revenue, MRR or verified traffic. Every visible customer, address, job, image and statistic is demo/sample data. Hosting, domain, Telegram account, cloud credentials and customer data are not included. Customer confirmation is an acknowledgment, not a qualified electronic signature, and legal enforceability is not guaranteed. The buyer must adapt Privacy Policy and Terms for the relevant jurisdiction. Exclusive-rights terms must be agreed separately.VERIFICATIONThe critical backend workflow passed 18/18 release checks, including Telegram HMAC validation, RBAC, IDOR isolation, state transitions, PDF generation and hash verification, idempotent completion, temporary sharing and invalid upload rejection. TypeScript, lint and SQLite migration checks passed. Docker/PostgreSQL runtime verification remains the buyer's deployment step because Docker was unavailable in the build environment.
