user registration.<h2>How the Sign-Up Fee Works</h2><ul class="accent-bullets"><li>Charged once during initial registration</li><li>Can include credits, promotions, or vouchers</li><li>Required only for private trips</li></ul>Important<ul class="accent-bullets"><li>The sign-up fee must be paid for private trips</li><li>Business trips can be taken without paying the sign-up fee</li></ul><img

data-original-src="https://uploads.productlane.com/37faa76bfda3bf2071ca847c420c58ee.png"><h2>Reducing Friction While Keeping the Sign-Up Fee</h2>Even when a sign-up fee is active, operators can return value to the user to reduce friction while still improving signup quality.Common approaches include:<h3>Promotion-based value return</h3><ul class="accent-bullets"><li>The user pays a sign-up fee (for example, €10).</li><li>A promotion is automatically applied or assigned that grants equivalent or higher value (for example, €10 driving credit for the first trip).</li><li>This creates a commitment signal while keeping the perceived cost neutral for the user.</li></ul>This approach is commonly used to:<ul class="accent-bullets"><li>Reduce fraud</li><li>Increase signup quality</li><li>Maintain high conversion rates</li></ul><h3>Voucher-based free sign-up testing</h3><ul class="accent-bullets"><li>Operators can distribute vouchers that effectively cover the sign-up fee.</li><li>Selected users can complete registration and test the service without upfront payment.</li><li>Typical use cases:<ul class="accent-bullets"><li>Pilot phases</li><li>Partnerships</li><li>Marketing campaigns</li><li>Customer support exceptions</li></ul></li></ul>This allows operators to keep the sign-up fee active while selectively lowering friction.<hr><h2>Advantages of a Sign-Up Fee</h2><ul class="accent-bullets"><li>Reduces fraudulent or low-quality signups</li><li>Covers costs for verification or operations</li><li>Creates early commitment from users</li><li>Can be combined with promotions or vouchers to return value</li></ul><h2>Disadvantages of a Sign-Up Fee</h2><ul class="accent-bullets"><li>Adds friction to the onboarding flow</li><li>Can reduce conversion if the value is not clearly communicated</li><li>Requires careful positioning in the app and onboarding messaging</li></ul><h2>Introducing a Sign-Up Fee After Go-Live</h2>If you introduce a sign-up fee after your service has already gone live, special handling is required for users who signed up before the fee was active.By default, these existing users have not paid a sign-up fee. Before enabling the fee, operators must define how these users should be treated.This must be planned and communicated in advance with Wunder Mobility Customer Success.<hr><h3>Required Pre-Configuration Decisions</h3>Before going live with a sign-up fee, operators must decide which existing users are considered as having already paid the sign-up fee.The most common options are:Option 1: Users with at Least One Completed Rental<ul class="accent-bullets"><li>All users who have completed at least one rental are treated as if they already paid the sign-up fee.</li><li>No retroactive charge is applied.</li></ul>Typical use case:<ul class="accent-bullets"><li>Operators want to avoid friction for already active users.</li><li>Sign-up fee applies only to new users.</li></ul><hr>Option 2: Users with Driving License Verification Completed<ul class="accent-bullets"><li>All users who have completed KYC verification are treated as having paid the sign-up fee.</li><li>Users without verification may still be required to pay.</li></ul>Typical use case:<ul class="accent-bullets"><li>Operators associate the sign-up fee with identity or eligibility checks.</li><li>Common for car sharing operations.</li></ul><hr>Option 3: All Existing Users Must Pay Retrospectively<ul class="accent-bullets"><li>All existing users are required to pay the sign-up fee before starting their next private trip.</li><li>No users are grandfathered.</li></ul>Typical use case:<ul class="accent-bullets"><li>Operators want a consistent rule set for all users.</li><li>Requires clear communication to avoid support load.</li></ul><hr><h3>Coordination with Customer Success</h3>Once a decision is made, the operator must:<ul class="accent-bullets"><li>Inform Customer Success of the chosen approach</li><li>Define the exact cut-off logic</li><li>Align on the go-live date</li></ul>Customer Success will then:<ul class="accent-bullets"><li>Prepare the required configuration</li><li>Apply the sign-up fee logic to existing users</li><li>Ensure the sign-up flow and rental logic behave as expected</li></ul>This preparation is treated like any other configuration change and should be planned accordingly.<hr><h3>Important Notes</h3><ul class="accent-bullets"><li>Retroactive handling is not automatic</li><li>Decisions cannot be changed easily after go-live</li><li>Clear communication to users is strongly recommended</li><li>Testing in a non-production environment is advised</li></ul>Introducing a sign-up fee post–go-live should always be handled as a planned rollout, not a toggle change.<hr><h1>Configuration and Support</h1>All sign-up and login options are configured with support from Wunder Mobility Customer Success.Customer Success can help with:<ul class="accent-bullets"><li>Selecting the right sign-up method</li><li>Enabling or disabling phone, email, or social logins</li><li>Configuring phone number rules</li><li>Setting up or adjusting the sign-up fee</li><li>Coordinating app updates if required</li></ul>Operators should always test configuration changes in a non-production environment before going live.<hr><h1>Tips and Best Practices</h1><ul class="accent-bullets"><li>Use one clear primary login method to keep onboarding simple.</li><li>Add social logins if fast conversion is a priority.</li><li>Clearly explain the value of the sign-up fee if enabled.</li><li>Align sign-up options with your target market and fraud risk.</li><li>Involve Customer Success early when planning changes.</li></ul><hr><h1>Troubleshooting</h1><h2>Users cannot sign up</h2><h3 class="p4">Possible causes</h3><ul class="accent-bullets"><li>Conflicting login methods enabled</li><li>SMS or email delivery issues</li></ul><h3 class="p4">What you can do</h3><ul class="accent-bullets"><li>Confirm the active login method with Customer Success</li><li>Test the sign-up flow with a new test user</li></ul><hr><h2>Users are blocked by the sign-up fee</h2><h3 class="p4">Possible causes</h3><ul class="accent-bullets"><li>User is attempting a private trip without paying the fee</li><li>Business account not correctly assigned</li></ul><h3>What you can do</h3><ul class="accent-bullets"><li>Confirm whether the trip is private or business</li><li>Ask Customer Success to verify user account setup</li></ul>
