The cost of neobank app development can include several hidden charges that are easy to miss in the beginning. These might be fees for using third-party APIs, charges for cloud services, legal approvals, app store listing costs, and tools used for testing the app with real users. After the app is live, you will also need money for marketing and customer support. If you don’t plan for these early, your budget can grow quickly. It’s a good idea to keep some extra money aside when estimating your overall neobank app development cost.
