  • Expert guidance and consultation
  • Improved operational efficiency
  • A read on where the sector is going

Custom software development

Platform-based systems built from scratch for real-time data interaction, bespoke reporting and the customer engagement a bank actually needs, rather than the subset a product happens to offer.

Guide

Understanding Banking Software Development

Five questions that come up in every banking build, answered in the order they tend to arrive. Pick the one you came for.

The benefits and challenges of digital banking

Digital banking (neo-banking, branchless banking) delivers the whole product through web and mobile. Lower cost to run, a better interface and smarter features are what make it attractive. These are what make it hard.

  1. What a branchless bank has to solve

    • Cybersecurity measures that hold against a well-funded attacker
    • Building and running the platform itself, with no branch network to fall back on
    • Compliance with a regulator that was written for the branch model
    • Protecting financial data and customer information at every hop
    • Keeping service quality intact through a traffic spike

How banks keep data safe

Four controls do most of the work. None of them is optional, and the gap between having them and having them configured properly is where incidents happen.

  1. Encryption

    Data converted into a form that is useless to whoever intercepts it. This is what makes the difference between a data breach and an attempted one.

  2. Robust authentication

    Multi-factor authentication to verify who is actually asking. It is the control that stops a stolen password from being enough.

  3. Regulatory compliance

    Adherence to the regimes that apply, PCI DSS, GDPR and their regional equivalents. Compliance is the floor for how financial data has to be handled, not a certificate to hang up.

  4. Software updates

    Regular patching across the stack, so a known vulnerability does not stay open. Most successful attacks use one that was already published.

Navigating regulatory compliance in banking

Banks operate in one of the most heavily regulated environments there is, and the detail varies by region. The themes do not.

  1. What the regulation covers

    • Anti-money laundering (AML)
    • Know Your Customer (KYC) procedures
    • Data privacy and protection
    • Authentication of electronic transactions
    • Licensing and operation of digital payments
    • Cryptocurrency regulation
  2. How to stay on top of it

    • Update policy as the rules move, not annually
    • Implement the data protection the rules assume
    • Train the people the compliance actually depends on
    • Work with legal specialists in the jurisdictions you operate in

The technologies behind financial software

Six technologies currently doing the heavy lifting in financial software, and what each is genuinely good for.

  1. AI and machine learning

    Faster, more accurate analysis than a rules engine, which is what improves both the decision and the experience around it.

    • Customer service
    • Fraud detection
    • Risk assessment
    • Personalised recommendations
  2. Blockchain

    Transparency and immutability in transaction handling, useful specifically where several parties need to agree on one record.

    • Digital currencies
    • Cross-border payments
    • Smart contracts
    • Identity verification
  3. Robotic process automation

    Automating the repetitive work where human error is the main failure mode, and where the cost is the volume rather than the difficulty.

    • Data entry
    • Report generation
    • Compliance checks
    • Customer onboarding
  4. Internet of Things

    Sensors and wearables generating behavioural data that a financial system can act on.

    • Personalised financial products
    • Real-time monitoring for fraud
    • Risk assessment from behavioural patterns
  5. Cloud computing

    Scalability and cost control, and the reason a startup can stand up a banking application at all.

    • Secure storage and integration
    • On-demand compute
  6. APIs and open banking

    Controlled data sharing between institutions and the software around them, the foundation most fintech products are built on.

    • Banking system integration
    • Seamless transactions
    • Personalised experiences

Mobile payments: trends and what comes next

Mobile wallets keep payment credentials on the device and settle contactless. Convenience is why they won. These are the two sides of where they are now.

  1. Challenges

    • Security gaps, and updates that arrive late
    • A fragmented market of competing platforms
    • Phishing, and the absence of a common standard
  2. Opportunities

    • Cash flow that arrives faster and more predictably
    • Loyalty programmes that integrate rather than bolt on
    • Cardless transactions that settle quickly

Everything you need to know about building banking software. Can’t find your answer? Get in touch.

Software built to run banking and financial operations, used by banks, financial institutions and credit unions to manage accounts, handle transactions, meet regulatory obligations and keep the whole operation coherent. It usually covers:

  • Core banking systems
  • Mobile and online banking
  • Customer relationship management
  • Payment processing
  • Investment management

By working out what a customer needs before they have to ask for it. In practice that means:

  • Personalised product recommendations
  • Virtual assistants and chatbot support
  • Fraud and scam detection
  • Sentiment analysis on customer feedback
  • Automated wealth management

The ones currently doing most of the work on security, usability and function:

  • Artificial intelligence
  • Blockchain
  • Cloud computing
  • Biometric authentication
  • Internet of Things
  • Voice recognition

Through RESTful APIs, which is what makes cross-channel behaviour work: real-time transfers between accounts, access to statements, and a consistent view of a customer whichever channel they arrive through.

A basic system runs roughly $30,000 to $60,000 over three to six months; one with custom features $60,000 to $150,000 over six to nine months; and a genuinely complex system $150,000 to $250,000 over nine to twelve. Interface design, platform choice, feature set, team size and location all move the figure.
