Win with finance software development that grows with you
Innovate faster with custom banking technology solutions. Your vision, our code — powering next-gen banking solutions.
Need financial technology that actually does the job? We build custom fintech software solutions that handle fraud prevention, compliance headaches, and endless spreadsheets, so you don’t have to. Whether you’re streamlining transactions, hardening security, or personalizing digital banking experiences, our approach is simple: build what works, automate what slows you down, and scale where it brings long-term ROI.
Software development for financial services
COAX’s skilled finance software developers design finance software for budgeting trackers, automated savings tools, and debt management systems that sync with real-world spending. These systems automatically reconcile transactions across banks, enforce customized budget rules, and accelerate debt payoff through behavioral nudges.
We build mobile payment apps, e-commerce checkout systems, and peer-to-peer transfer platforms that handle transactions securely in real-time. These solutions let businesses accept payments anywhere, send money instantly between users, and avoid fraud with built-in verification, keeping money moving smoothly without delays or security risks.
Our developers create advisor platforms, client portfolio dashboards, and automated rebalancing tools as part of our financial software development services. With these tools, advisors manage more accounts efficiently while giving investors self-service access to their holdings with performance tracking and no spreadsheets or manual updates needed.
We develop cash flow predictors, spending pattern analyzers, and risk scoring models that process raw transaction data into actionable insights. These tools forecast short-term liquidity gaps and quantify financial health metrics, giving your business or individual finances a great data-driven clarity without manual analysis.
With our fintech product development expertise, you get efficient, tailored underwriting engines, dynamic credit scoring models, and loan management systems. These platforms assess borrower risk, adjust credit limits based on real-time behavior, and handle collections, reducing default rates and approving more qualified applicants faster.
Our experts craft automated KYC/AML screening systems, transaction monitoring algorithms, and compliance report generators that validate identities and flag suspicious activity in real-time. This allows you to reduce manual review workload, prevent fraudulent transactions before completion, and maintain audit-ready records to satisfy financial regulators.
Banking software development
/ 01
Core banking systems
Our software development in banking delivers centralized account hubs, batch payment processors, and customer balance APIs that replace legacy infrastructure. You get a single system that processes loans, manages customer accounts, and settles interbank transactions, cutting operational costs and reducing errors to near zero.
/ 02
Online banking platforms
We develop web-based account dashboards, bulk payment modules, and statement customization tools that replicate full branch functionality online. These platforms let customers approve wire transfers, analyze spending patterns, and download tax-ready transaction historiesб, eliminating branch visits for routine operations.
/ 03
Mobile banking app development
We create instant balance checkers, cardless ATM access, and voice-activated transfers for banks needing modern mobile payment app development. These features let users check balances without logging, withdraw cash via QR codes, and send money hands-free.
/ 04
Accounting & tax software
Our specialists build bank transaction categorizers, real-time tax liability trackers, and multi-currency reconciliation tools that automate manual bookkeeping. These systems auto-match invoices to payments, calculate obligations per transaction, and flag discrepancies before closing periods, cutting accounting errors and month-end close time.
/ 05
Banking CRM & customer analytics
Our financial software development company also specializes in building customer segmentation engines, product affinity predictors, and lifetime value calculators. With such tools at hand, you identify cross-sell opportunities, predict churn risks in advance, and prioritize high-value clients, increasing revenue per customer.
/ 06
ERP banking systems
We set intercompany settlement automations, liquidity forecasting modules, and branch performance dashboards that connect front/back-office banking operations. You gain real-time visibility into portfolio concentrations, automate compliance checks, predict cash positions, and flag underperforming products to allocate resources better.
What we offer for custom fintech solutions
Discovery Phase
We analyze your transaction flows, compliance requirements, and integration points to create a fintech software outsourcing roadmap that actually works. You’ll get a technical playbook detailing API specs, security protocols, and scalability thresholds, so your team knows exactly what’s being built and why.
UX audit
We methodically examine every tap, swipe and hesitation in your financial app using granular session analytics and accessibility compliance checks to reveal the hidden pain points. Our report delivers specific, actionable fixes, like streamlining ID verification flows or repositioning critical CTAs, based on empirical user behavior data.
Fintech web development
We engineer web platforms for financial workflows where fintech solution development meets real-world demands, with features like instant payment status updates, live fraud monitoring, and multi-institution account aggregation without page reloads. With us, you get performant web interfaces for complex financial operations without sacrificing speed or compliance.
Mobile design and development
Our engineers develop financial apps where biometric logins and animated transaction confirmations make security feel effortless. You get native iOS/Android apps that handle sensitive operations like loan approvals or stock trades while staying compliant, offline-capable, and unexpectedly quick — even on older devices.
Quality assurance
We simulate real-world financial chaos, like sudden rate fluctuations, simultaneous multi-device logins, and API throttling scenarios, to expose weaknesses before they impact customers. Our reports typically expose how failures could actually lose money, like decimal point errors in interest calculations or race conditions in high-frequency trading modules.
AI/ML integration
Our approach to AI in software development in banking and finance focuses on what matters: algorithms that explain their decisions for compliance, prediction models that improve weekly, and chatbot resolvers that handle the most common inquiries without human help. The result? You get measurable improvements, like cutting false positives and catching more actual fraud.
Payment gateways
Your gateway should work harder than you do, and we build systems that switch between processors when one goes down and instantly retry failed transactions without customers noticing. You get failure recovery that retries declined transactions across backup providers, plus real-time currency arbitration that picks the cheapest settlement path.
Regulatory compliance & risk mitigation
Software development for finance should be iron-safe. We build fintech software that meets strict regulations (GDPR, PSD2, AML, SOC 2) from the start. Get automated compliance checks, real-time fraud alerts, and systems that adapt to new rules effortlessly. Stay secure and avoid costly fines with ironclad protection for every transaction.
