Digital Banking Software We Build

Every engagement starts with how your customers, and your institution actually bank and ends with a production system. Here is the range of digital banking technology we deliver for banks, neobanks, and credit unions.

Mobile Banking App Development

The mobile app is now the primary branch for most customers, and its quality shapes how they judge the institution behind it. Hence, our mobile banking app development delivers secure, intuitive iOS and Android applications for accounts, payments, transfers, and card controls. Our mobile banking platforms are engineered to increase engagement and reduce workloads at branches and call centers.

Digital Banking Platform Development

Fragmented systems limit how fast an institution can launch and adapt. Our digital banking platform development consolidates accounts, payments, lending, and onboarding into a single core. Moreover, the platform is API-first and cloud-native, and it scales with the institution and integrates cleanly with existing infrastructure.  

Core Banking Modernization  

Legacy cores constrain every product launch and inflate operating cost. Our core banking modernization services transition the institution toward a flexible, cloud-native architecture in measured stages, reducing risk and improving performance while the bank stays operational throughout the migration.

Neobank Development

Launching a challenger bank demands a modern core and a fast route to market. Drawing on a delivered blockchain-based neo-bank that brought open financial infrastructure and programmable savings and payments to emerging markets, our neobank development covers account opening, payments, cards, and lending on an API-first foundation built to scale.

Digital Onboarding & eKYC Solutions  

Account opening is the point where most prospective customers are lost. Our digital onboarding and eKYC solutions verify identities, capture documents, and run automated checks in minutes, meeting compliance requirements while removing the friction that drives sign-up abandonment.

Lending & Loan Management Software  

A fully automated commercial real estate lending platform we delivered manages contracts, lifecycle, and analytics end-to-end. Our lending and loan management software applies the same discipline across origination, underwriting, servicing, and collections, with credit decisioning integrated throughout the loan lifecycle.

Open Banking & API Development

Open banking positions the institution as a platform that partners and third parties can build upon. Our open banking API development delivers secure, standards-based APIs, including Swiss bLink connectivity, that enable account access, payment initiation, and third-party integration across the financial ecosystem.

Banking-as-a-Service (BaaS) Development  

Embedded finance lets banking products generate revenue wherever partners operate. Our BaaS platform development exposes accounts, payments, and cards through clean APIs, enabling institutions to embed banking into third-party applications and open new distribution channels.

White-Label Digital Banking Platforms

Speed to market often decides which entrant captures a segment first. Our white-label digital banking platforms launch under the client's brand on a customizable foundation for mobile and web banking, giving institutions and fintechs a faster, controlled path to production.

How do Webmob experts build digital banking software?

We build digital banking systems on a clear ROI path: lower operating costs, speed up onboarding and product launches, strengthen compliance, and help institutions grow their customer base and revenue.  

The steps we follow:

Arrow LeftArrow RIght

Strategy & Integration

We define our banking model before the technological stack. We map out all your products, user experience journeys, integrations, regulations, and KPIs that matter, so the platform is designed around the experiences that matter most to make you more efficient and successful.

Discovery  

We evaluate the environment in which the system operates: the number of customers, core and payment integrations, onboarding processes, lending needs, and compliance requirements you need to meet, such as those set by FINMA and FADP. You get a roadmap of what will be delivered and when.

Design & Architecture 

Prior to development, Webmob develops the architecture for the riskiest parts of the system – integration, onboarding, API layers, and security. Our design is built on API-first and cloud-native principles to ensure scalability and auditability, as well as readiness for banking regulation.

Development & Rail Integration

Our development follows a process of secure and agile sprints that validates the platform in relation to performance, compliance, and business requirements. In this phase, the system is built and integrated with core banking and payment rails, open banking APIs (bLink), and eKYC providers.

Testing, Security & Certification  

Launching a Bank requires validation. Tests will be conducted to ensure compliance with the FADP and PCI DSS, including security and penetration testing, accessibility verification, and validation of every flow prior to launch, ensuring that you get a fully tested platform.

Support

Banking platforms must update with regulations, customer expectations, and volumes. After launching, Webmob monitors performance, tunes the platform, ships regulatory and feature updates, and provides a 24-hour response standard to keep your banking infrastructure stable, compliant, and ready to scale.

Frequently asked questions

Explore answers to frequently asked questions about our service. Have a question that's not covered? Reach out to our team for personalized assistance.

How much does it cost to develop a digital banking platform?

Cost depends on scope: the number of products, the depth of core integration, the onboarding and lending modules, and the compliance requirements. We scope digital banking software development against your roadmap and provide an itemized estimate before development begins.

How long does it take to build a mobile banking app?

Timelines depend on features and integrations. A focused mobile banking app ships in a few months; a full platform with core integration, onboarding, and lending runs longer. Discovery delivers a roadmap with milestones you can track.

Can you modernize our core banking system without downtime?

Yes. Our core banking modernization services migrate in measured stages, running new and legacy components in parallel to keep the bank live. This phased approach reduces risk and lets you retire legacy systems once each stage proves stable.

Do you build white-label digital banking platforms?

Yes. Our white-label digital banking platforms launch under your brand on a customizable foundation for mobile and web banking, giving banks and fintechs a faster path to market with full control over experience, products, and configuration.

How do you ensure compliance with FINMA and Swiss data-protection law (FADP)?

We engineer FINMA-aligned governance and FADP controls into the architecture from the first sprint, covering consent, data minimization, audit trails, and breach handling. The revised FADP, effective as of September 2023, aligns closely with the GDPR.

 How do you build a neobank from scratch?

We build neobanks on a modern, API-first core covering account opening, payments, cards, and lending, moving from strategy and compliance through design, build, integration, and launch. We have delivered a blockchain-based neo-bank with open financial infrastructure.

Do you support open banking and bLink API integration in Switzerland?

Yes. Our open banking API development builds secure, standards-based APIs, including Swiss bLink connectivity, enabling account access, payment initiation, and third-party integrations, designed to meet Swiss market standards and connect cleanly to your core systems.

How do you implement digital onboarding and eKYC compliantly?

Our digital onboarding and eKYC solutions verify identity, capture documents, and run automated checks in minutes, built to satisfy FADP and AML requirements. Compliance controls sit in the flow from the first sprint, keeping onboarding fast and compliant.

Can you build custom lending and loan management software?

Yes. We built a fully automated commercial real estate loan platform covering contract negotiation, lifecycle management, and analytics. Our lending and loan management software handles origination, underwriting, servicing, and collections, with credit decisioning across the loan lifecycle.

Should we choose a custom build or a platform like Temenos or Backbase?

Off-the-shelf platforms deploy faster and suit standard needs. A custom build provides tailored workflows, the integrations your stack requires, and freedom from recurring licensing costs, protecting the products or experiences that set your institution apart.
