Banking

Customers expect digital-first banking, but legacy infrastructure makes it nearly impossible to deliver.

Banks and credit institutions face a dual challenge: modernizing customer-facing digital experiences to compete with neobanks and fintechs, while maintaining the security, reliability, and regulatory compliance that their charter demands. Core banking systems are often decades old, making it expensive and risky to introduce new products or integrate modern APIs. Kiloctet builds the digital layers — mobile apps, customer portals, open banking integrations, and back-office automation tools — that let banks move faster without replacing the stable infrastructure they depend on.

What we build

Banking software solutions we provide

01

Digital Banking Web and Mobile Platform

A secure, feature-rich digital banking application covering account management, fund transfers, bill payments, transaction history, and document uploads for both retail and business customers. The platform is built with multi-factor authentication, end-to-end encryption, and session security best practices to meet the security expectations of regulators and customers. Configurable product templates make it straightforward to add new account types or loan products without a full redevelopment cycle.

02

Loan Origination and Processing System

Automates the full lifecycle of retail and business loan applications — from customer-facing application forms and document collection through credit assessment, underwriting decisioning, approval workflow, and disbursement. Integration with credit bureaus, identity verification services, and core banking systems eliminates manual data entry and accelerates processing times from days to hours. Built-in audit trails and configurable decisioning rules support regulatory compliance and fair lending requirements.

03

KYC and Onboarding Automation Platform

A digital onboarding journey that guides new customers through identity verification, document submission, risk assessment, and account opening without requiring a branch visit. Integration with government ID verification APIs, biometric checks, and sanctions screening lists ensures compliance with AML and KYC regulatory requirements. Automated risk scoring assigns customers to appropriate due diligence tiers, streamlining the compliance review process.

04

Open Banking API Gateway

A standards-compliant API layer (PSD2, Open Banking UK) that exposes account data and payment initiation capabilities to authorized third-party providers while enforcing strong customer authentication and consent management. The gateway logs all API calls for regulatory audit purposes and enforces rate limiting and security controls to protect core systems from exposure. Banks can use the same infrastructure to build their own BaaS (Banking as a Service) propositions.

05

Back-Office Operations Automation Suite

A set of workflow automation tools that replace manual paper-based processes in areas such as account maintenance, complaint handling, payment exceptions, and regulatory reporting. RPA-style automation handles repetitive data extraction and entry tasks between legacy systems, while case management tools give operations staff a structured interface for handling complex customer requests. Reduction in manual processing time typically reaches 40–60% for targeted workflows.

Why bespoke

Benefits of building bespoke solutions

01

Competitive Digital Experience Without Core Replacement

Banks can deliver modern mobile apps, instant account opening, and real-time payment notifications by building a digital layer on top of their existing core banking infrastructure rather than undertaking a high-risk core replacement program. Middleware and API integration patterns allow new digital features to be launched in months rather than years. This approach lets banks compete on customer experience with neobanks while maintaining the stability and compliance record of their proven core systems.

02

Faster Loan Processing and Higher Conversion

Automated loan origination systems dramatically reduce the time from application to decision, which directly improves conversion rates as fewer applicants abandon the process due to delays. Integrations with credit bureaus and income verification APIs enable near-instant decisioning for standardized loan products. Banks that have automated origination typically see a 50–70% reduction in processing time and a measurable improvement in customer satisfaction scores for lending journeys.

03

Reduced Compliance Risk and Audit Readiness

Digital onboarding with automated KYC, AML screening, and comprehensive audit trails significantly reduces the manual compliance burden while improving the quality and completeness of compliance documentation. Real-time monitoring rules flag suspicious transactions automatically, reducing the risk of regulatory findings. When auditors request evidence, reports are generated from system logs in minutes rather than assembled from paper files over days.

04

Lower Operational Cost Through Back-Office Automation

Banking operations are heavily labor-intensive, with large teams processing routine requests, handling exceptions, and preparing reports. Automating these workflows with intelligent routing and RPA-style tools typically reduces the labor cost of targeted processes by 40–60% while improving accuracy and turnaround times. Staff freed from routine processing can be redirected to relationship management and complex customer service tasks.

05

New Revenue Streams Through Open Banking and BaaS

Building a compliant open banking API gateway positions the bank to participate in the growing ecosystem of third-party financial services and Banking as a Service propositions. Embedded finance partnerships, where your accounts and payment rails are offered as infrastructure to non-bank businesses, create fee income streams that don't require growing the retail deposit base. This is particularly valuable for smaller banks and credit institutions looking for growth beyond their geographic or demographic footprint.

Common questions

FAQ

Security is embedded into every phase of our development process, not added as an afterthought. We follow OWASP security guidelines throughout development, conduct threat modeling during design, and perform static code analysis and penetration testing before any release. All sensitive data is encrypted at rest and in transit, and we implement robust authentication mechanisms including multi-factor authentication and session management best practices. We also support banks in preparing the security documentation required by regulators such as Bank Al-Maghrib, the ECB, or local central banking authorities.
Yes. We have experience building integration layers with a range of core banking systems including Temenos T24, Oracle FLEXCUBE, Mambu, and older proprietary platforms via SOAP, REST, or direct database integration where API access is not available. We approach core banking integration conservatively — always preferring read-oriented patterns and using message queuing to decouple new systems from the core so that a failure in a new service cannot destabilize the core. Detailed integration mapping and testing in a sandbox environment are standard parts of our engagement process.
Banking software handles highly sensitive personal and financial data, so data privacy is a foundational concern. We design data models with minimal retention, implement role-based access controls that limit who can see customer data, and build consent management and data subject request handling (right to access, right to erasure) into the platform from the start. All data processing activities are documented for Records of Processing Activities (ROPA) purposes. We work with your DPO during the design phase to ensure the architecture meets your GDPR and local data protection obligations.
Yes. We design banking applications with role-based product views so that a single app codebase can serve retail customers with personal account features and business customers with multi-user access, approval workflows, bulk payment uploads, and treasury management tools. The apps are built natively for iOS and Android or using React Native where a cross-platform approach is preferred for budget reasons. We handle the full submission process to Apple App Store and Google Play, including financial services category compliance requirements.
We have built PSD2-compliant API gateways covering both Account Information Services (AIS) and Payment Initiation Services (PIS) capabilities, with strong customer authentication (SCA) implemented via FIDO2/WebAuthn and one-time passcodes. The APIs conform to the Berlin Group NextGenPSD2 specification and include the consent management, authorization, and audit logging infrastructure required for regulatory compliance. We also advise on eIDAS certificate requirements and support banks through the registration and testing process with national competent authorities. Our open banking implementations are designed to be extensible so the same infrastructure can support future regulatory requirements.
