What is yo banking app development process? How is the workflow organized?
We follow a comprehensive yet flexible banking software development process. First, we discuss your goals and high-level requirements, define the project scope, decide on third-party providers, and create a preliminary delivery schedule. Then, our business analysts determine the detailed requirements while UI /UX specialists design an intuitive and visually appealing user interface. After you approval the requirements and UI, Itexus’ experienced banking app developers, guided by a solutions architect, deliver increments using an iterative approach (with 2–4 week iterations). Delivered increments are tested by our QAs to ensure quality. Concurrently, our backend team implements integrations with required third-party services(the selection of suitable third-party providers takes time, so we recommend choosing them at the very beginning of the project). Throughout all phases, our experienced project managers ensure that deliveries are on time and on budget, and keep you regularly updated on progress. Once complete, the project team releases the application and submits it to the app stores if required.

We’ve established partnerships with leading third-party providers and have extensive experience integrating financial software with payment gateways, KYC providers, BaaS platforms, credit scoring systems, electronic signature providers, and other services. If you’re unsure about which providers are right for you, our specialists will be happy to conduct research and offer you the best options that meet all your needs.
