  • Collect Receipts

  • Save Money

    With wunderbon it is so easy to save money! We analyse your receipts - no matter from which source - for cashback offers from manufacturers (food, cosmetics, electronics, etc.) and then automatically activate them for you - WITHOUT you having to activate or even print out a coupon. This is automatic saving!

    wunderbon aggregates your issues and displays them clearly. By analyzing your receipts you get a complete overview divided into different areas and this helps you to keep an eye on your expenses. Our Budget Butler informs you according to your wishes and rules. So you always have your expenses in view.

  • How much is wunderbon?

    wunderbon is free and always will be. Both our app on Android and Apple iOS and your account are 100% free.

  • Does wunderbon work on any device?

    We support the two major mobile platforms Google Android (from version 8.0) and Apple iOS (from version 12.0). Currently no further adaptations are planned. This may change depending on demand.

  • Is my data safe?

    We do everything we can to protect your data! Nobody but you can see your data. Companies (merchants & cashback/coupon providers) you actively share your data with will see exactly the information you selected in your share. Nothing more. All data is transmitted exclusively in encrypted form and stored securely within the EU in compliance with the DSGVO. You can delete your account completely at any time. Important: Use a secure password and keep your password secret. This is the most important condition for the protection of your data!

  • Are digital receipts legally valid?

    A receipt generated digitally by wunderbon's trading partners is legally valid for the guarantee and warranty and serves as proof of the tax return. When digitizing paper receipts, care must be taken to photograph the complete receipt. This is the only way for the retailer to find all the relevant information on it in the event of an exchange. In individual cases, the acceptance of digitized paper documents depends on the goodwill of the retailer. Should there be any difficulties, please call us or send us an e-mail.

  • Can I export my receipts?

    wunderbon stands in its basic principles for high data protection, self-determination over the use of the data as well as a customer-friendly regulation concerning the export of the own data. You can export your data free of charge at any time. You can access this via your account management on the web. The adapted export for the most common tax programs, however, is only available as part of a premium subscription.


wunderbon will soon be available for your Android smartphone (Google Play Store) or iPhone (Apple iOS App Store). Use our Early-Bird-Program to make sure you don't miss the launch and be among the first to benefit.
