ValueDocStill under construction: let me know when it starts
Enter your email. When ValueDoc starts, you'll get one mail with the link to the app. That's all we send.
Almost done: please confirm the link in the mail we're sending you now. Check your spam folder too.
Why a complete record pays off
Nobody likes buying second-hand blind. If you can show what was done, you hold the better cards.
When you sell
Every service with date and invoice, as a link with QR code and no personal data. The buyer sees what they're buying. That builds trust and can support the price.
With warranty claims
The proof of purchase is right there when the battery weakens or the heating breaks down. You see the end of the statutory warranty as a guide value (no guarantee, not legal advice).
With theft and damage
Frame number, photos and invoice are ready for the police and your insurer. Once reported stolen, anyone can check the number.
Without receipts
- “It was always serviced,” says the seller.
- The invoices are somewhere in a folder.
- The buyer expects the worst and haggles.
With ValueDoc
- Every service with date, workshop and receipt.
- One link shows the whole history, without your address.
- On sale, the file moves to the buyer's account.
One file for everything you own
Everything in one place
House, two cars, e-bikes and scooters: with one email address you have all books neatly sorted by type. Every battery gets its own file.
Add your old service book
Photograph the pages of your old service book. Every line with a date becomes an entry, you just check it. Anything added later stays marked as such.
Home file
Heating, roof, windows, solar panels and battery storage: invoices, plans and reports with service life in view. You don't need to enter an address.
The right book for every category
Bicycle
Service, tyres, chain and brakes with date and receipt. Frame number and proof of purchase are right there if the bike is stolen.
E‑bike and pedelec
Plus a separate file for the battery with capacity, charge cycles and health. Ideal when returning a leased company bike. See an example
E‑scooter and e‑moped
Insurance plate, tyres, brakes and battery in one place. Add March as a due date and we'll remind you about the new plate.
Motorbike and e‑motorbike
Oil change, chain kit, tyres and season start by kilometres. A complete service history holds its value when you sell. See an example
Car, electric car and hybrid
Servicing, roadworthiness test, tyre changes and repairs as a digital service book. In an electric car or hybrid, the battery gets its own file. See an example
Motorhome and boat
Gas check, damp test, engine and winter storage. All invoices together, for the next buyer too.
House and home battery
The home file: heating, roof, windows, solar panels and storage with service life, energy-related and other work kept apart. See an example
Everything else
Ride-on mower, trailer, pram or wheelchair: under “Other” you say what it is. The book works just the same.
This is how simple it is
-

Take a photo
Photograph the invoice, type plate or registration document. A PDF works too.

Saved in the book
With date and receipt, and always at hand. Every change is logged.
Got a battery? It gets its own file
Batteries move between bikes, get replaced or are sold separately. In ValueDoc their history stays with the battery: purchase, charge cycles, health and all receipts.
When selling: a link or the whole file
Interested buyers get a link with a QR code that expires on its own and shows no personal data. On sale, the whole file moves to the buyer's account with a code.
Free and tied to nothing
Any brand, any drive, any workshop. Do the service yourself or have it done wherever you like. The invoice is proof enough.
Guide
Frequently asked questions
Why is it called ValueDoc?
Value as in worth, doc as in document. If you can prove how something was looked after, you are in a better position when selling, with warranty claims and with your insurer. Until November 2026 ValueDoc was called Voltdoc. Your account and your files stay as they are.
What does ValueDoc cost?
ValueDoc is free. All you need is an email address.
What is ValueDoc for?
For everything with or without a battery: bicycle, e-bike, pedelec, e-scooter, e-moped, motorbike, car, electric car, motorhome, boat and your house. Everything sits in one account with one email address. Every battery and every home storage battery also gets its own file.
Can I bring over my old service book?
Yes. Take photos of the pages of your old service book. Every line with a date becomes an entry. You just check it. Entries added later are marked as added later.
What is the home file?
The service book for your house: invoices, plans and reports on heating, roof, windows, solar panels and battery storage in one place, with the service life of each component. You don't need to enter an address.
I drive a car. Does ValueDoc replace the manufacturer's service book?
ValueDoc is your own, brand-independent service book. Many manufacturers now keep their service record only digitally at the dealer. In ValueDoc you also hold all invoices yourself, including those from independent garages, and get reminders for servicing and the roadworthiness test.
What do I record for a motorbike or scooter?
Oil changes, chain kit, tyres, brakes and the start of the season, and for a scooter also the insurance plate. Wear parts get a guide value in kilometres, so we can remind you in time.
Does ValueDoc help with a leased company bike?
Yes. When you return or buy out the bike, what counts is whether it was serviced. With ValueDoc you have all receipts with dates in one place and can show them as a link.
What goes into the home file, energy-related and other?
Energy-related means everything that saves energy: heating, insulation, windows, solar panels, battery storage. Other work includes the bathroom, wiring, water pipes or painting. Both go into the file with invoice and date. That helps with subsidies, tax, energy advice and selling.
Motorhome, boat or something else entirely?
That works too. Motorhome and boat have their own categories, and under “Other” you simply say what it is, for example a ride-on mower or a trailer.
Do I have to use a particular workshop?
No. You enter any workshop, or “self” if you did the service yourself. The invoice is the proof.
Is ValueDoc the EU battery passport?
No. From 18 February 2027 the manufacturer provides the official battery passport for new batteries. ValueDoc is your personal record of how the battery was used, looked after and checked.
How does my data get into the book?
You take a photo of the type plate, registration document or invoice. The app reads the values, you check and save. Digital PDF invoices are read right on your device.
What happens when I sell?
You share the book with a link or QR code that expires on its own and shows no personal data. Or you hand the whole file over to the buyer's account with a code.
Where is my data stored?
On our own server in the EU (Helsinki). There are no trackers and no ads. You can download or delete everything at any time.
Do I need an app from the app store?
No. ValueDoc runs in the browser and can be added to your home screen like an app.
Does ValueDoc remind me about the chain, brakes or oil change?
Yes. You enter wear parts with a guide value in kilometres and now and then the reading from the odometer. Shortly before it's due, you get an email.
What doesn't ValueDoc do?
ValueDoc documents and reminds. It doesn't assess brakes, calculate tyre pressure or replace a workshop. All the details are under What ValueDoc deliberately doesn't do.
Who is behind it?
ValueDoc is a service of Energieagentur Berger GmbH from Herbrechtingen, Germany. The company is certified to ISO 9001:2015 (TÜV SÜD, scope: consulting, training and preparation of energy advice reports, valid until 28 January 2029). ValueDoc itself is not part of this certification. Visit the energy agency (German)
