# Vihkin — The service history stays with the owner

Digital service history for cars, motorcycles, trucks, trailers and machines. The workshop files its report through a secure link, without creating an account.

- Year: 2025
- Stack: React, Vite, TypeScript, Supabase, PostgreSQL
- Our role: Product design, frontend, data model, SEO
- URL: https://vihkin.com

## The problem

Service history lives in paper booklets, invoices and conversations. At resale none of it can be proven, and changing workshop means the history stays with the old one.

## The solution

Every vehicle gets a digital profile with a service timeline. The owner sends the workshop a temporary link, the workshop files the report with photos and invoices, and the record stays with the owner for good.

## Key capabilities

- Secure workshop links, no registration
- Costs, documents and reminders
- Mileage and engine hours for machines
- Shareable history at resale

## The outcome

Live in three languages, covering everything from a motorcycle to a construction machine, with a free plan to start.
