Product Requirements Document

Original Business Idea

I run a small auto repair shop and track jobs on whiteboards. I want 'RepairTracker' - an app to manage which cars are being worked on and parts needed.

RepairTracker is a simple, mobile-friendly app for auto repair shops to track cars in progress, parts needed, and job status without relying on whiteboards or memory. It helps shop owners and technicians stay organized, reduce delays from missing parts, and give customers clearer updates while creating a more professional, data-driven workflow.

Business Goals

Reduce job coordination errors by 40% within 6 months of adoption.

Increase monthly active usage among shop staff to 80% of active repair jobs tracked in-app.

Improve customer update responsiveness by 50% through better visibility into job status and parts requirements.

Create a scalable SaaS product for small repair shops with strong retention driven by operational dependence.

Position the company as an innovation leader for independent auto repair workflows by replacing manual whiteboard processes with modern digital tracking.

User Goals

Help shop owners see every active vehicle, its status, and required parts at a glance.

Enable technicians to quickly record progress and parts needs from the shop floor.

Reduce missed parts orders and prevent vehicles from sitting idle while waiting for components.

Make it easier to communicate accurate status updates to customers and internal staff.

Improve team coordination so the whole shop can work from the same live source of truth.

Non-Goals

Not a full accounting, payroll, or invoicing system.

Not a consumer-facing appointment booking marketplace.

Not a deep diagnostic or repair manual platform for technical troubleshooting.

Not designed to manage multi-location enterprise dealer networks in version one.

Personas & Stories

Shop Owner Maria, 46, process-focused and busy managing day-to-day operations

Maria runs a small independent repair shop with 4 technicians and multiple cars in progress every day. She currently uses a whiteboard and paper notes, and she needs better visibility without adding overhead.

As a shop owner, I want to see all active jobs and their status in one dashboard, so that I can quickly identify bottlenecks and keep work moving.

Status changes update the board instantly for everyone.

If a technician is unavailable, the app warns but still allows assignment.

A timestamp records when the job entered each stage.

3
Add Parts Needed

Technicians or advisors can add parts directly to the job, turning vague notes into trackable blockers.

Users can enter multiple parts in one session.

The app highlights jobs that cannot progress until parts are received.

Clear color system for status, blockers, and urgency, with text labels to avoid color-only meaning.

Accessibility support including keyboard navigation, readable typography, and screen-reader labels.

Performance target of under 2 seconds for main board load on typical broadband connections.

Maria used to run her auto repair shop with a whiteboard full of car names, status scribbles, and sticky notes for parts. At first, that system worked because everyone knew the routine. But as the shop grew busier, a vehicle waiting on a simple sensor would get lost behind other jobs, customers would call for updates that nobody could confidently answer, and Maria spent too much time walking the floor to find out what was blocked. With RepairTracker, Maria now checks a live dashboard that shows every car, its status, and exactly what parts are needed. James updates a job from his phone the moment he discovers a missing component, and Elena can tell a customer whether their car is still being diagnosed or is waiting on an alternator. The shop feels calmer, customers trust the updates more, and Maria finally has a system that turns daily chaos into visible progress while giving the business the structure it needs to scale.

Use caching for frequently viewed dashboard data and status summaries.

Implement monitoring for latency, sync failures, and file upload errors to catch workflow disruptions early.

Potential Challenges

User adoption risk: shop staff may resist replacing the whiteboard, so onboarding must be fast and the interface extremely simple.

Data-entry friction: too many required fields could slow technicians, so the MVP should keep check-in lightweight.

Real-time sync complexity: multiple staff editing the same job needs conflict handling and clear timestamps.

Parts workflow ambiguity: shops vary in how they order and receive parts, so statuses must be configurable without becoming overly complex.

Monetization risk: small shops are price-sensitive, so the product must prove clear time savings and operational value quickly.
