Our software development services in detail
Custom Software Development
Custom software development means building an application specifically for your business process instead of bending your team around off-the-shelf tools. NNT Software designs, builds, tests and supports custom software for clients worldwide from its engineering centre in India, typically shipping a first working release in 6–12 weeks on fixed-price or monthly-team terms.
ERP Software Development
A custom ERP is one system connecting procurement, production, inventory, sales, dispatch and finance. NNT Software builds custom ERP software for manufacturers and distributors globally, deployed on cloud or on-premise and rolled out module by module, as a lower-cost and better-fitting alternative to heavily customised SAP, Oracle or Odoo installations.
Mobile App Development
NNT Software develops iOS and Android mobile apps for businesses worldwide using Flutter, React Native, Swift and Kotlin. We handle UX design, backend APIs, admin panels, Stripe or regional payment integrations, App Store and Google Play publishing, and post-launch analytics and support.
Web Application Development
Web application development is building browser-based software such as SaaS products, customer portals and dashboards. NNT Software builds secure, fast web applications for clients worldwide using React, Next.js, Astro, Laravel and Node.js — including multi-tenant SaaS, B2B ordering portals, marketplaces and internal tools.
AI & Automation Services
NNT Software builds practical AI and automation for businesses worldwide — AI agents and chatbots for WhatsApp and websites, document data extraction, retrieval-augmented knowledge assistants, demand forecasting and workflow automation using large language models. Projects start with one measurable process and typically go live in 3–8 weeks.
Cloud & DevOps Services
NNT Software provides cloud and DevOps services worldwide: migrating applications to AWS, Azure or Google Cloud, building CI/CD pipelines, containerising with Docker and Kubernetes, configuring backups and monitoring, and reducing cloud spend through right-sizing and reserved capacity — available as projects or a managed monthly service.
UI/UX Design
UI/UX design shapes how software looks and how easily people complete tasks in it. NNT Software offers user research, information architecture, wireframes, interactive Figma prototypes, design systems, WCAG 2.2 accessibility and usability testing for web, SaaS and mobile products used worldwide.
Software Testing & QA
NNT Software provides independent software testing and QA outsourcing, including manual functional testing, test automation with Playwright, Selenium and Appium, API testing, load and performance testing, and OWASP-based security testing for web, mobile and enterprise applications.
QA Testing Services
QA testing services are structured quality assurance activities that verify an application works correctly, reliably and according to business requirements. NNT Software tests functionality, usability, user roles, business workflows and data accuracy, then gives engineering leads a written release-readiness recommendation.
Automation Testing Services
Automation testing services use scripts and frameworks to run repeated checks automatically on every build. NNT Software builds maintainable Selenium, Playwright and Cypress suites, API automation and CI/CD integration so critical workflows are re-verified in minutes instead of days.
Manual Testing Services
Manual testing services use experienced testers to execute test cases and explore an application the way real users do. NNT Software provides functional, UI and UX, exploratory, smoke and manual regression testing, with every defect documented with steps to reproduce and evidence.
Mobile App Testing Services
Mobile app testing services validate the functionality, usability, performance, compatibility and security of Android, iOS and cross-platform apps. NNT Software tests on a real device matrix across OS versions and network conditions and delivers a release-readiness report before store submission.
Website Testing Services
Website testing services verify that a site works correctly across browsers, devices and screen sizes. NNT Software tests functionality, forms, checkout and payment paths, navigation, responsive layouts and accessibility basics so visitors can complete tasks without friction.
API Testing Services
API testing services verify that the interfaces between your systems return the right data, handle errors and stay secure and fast. NNT Software tests REST and GraphQL APIs with Postman and code-based suites, covering authentication, validation, payment flows, performance and API security.
Performance Testing Services
Performance testing services measure how fast and stable an application stays under expected and extreme load. NNT Software runs load, stress, spike and endurance tests with JMeter and k6, finds the bottlenecks and gives clear capacity numbers before launches, campaigns and peak seasons.
Security Testing Services
Security testing services find weaknesses in applications before attackers do. NNT Software performs OWASP-based testing of web applications, APIs and mobile apps, covering authentication, access control, injection and data exposure, and delivers a risk-ranked remediation list with retesting after fixes.
Database Management & Remote DBA
Remote DBA services mean an external team monitors and maintains your databases. NNT Software provides remote database administration for MySQL, PostgreSQL, Microsoft SQL Server, Oracle and MongoDB worldwide — covering performance tuning, backups and recovery, high availability, upgrades, migrations and 24/7 monitoring on monthly plans.
Blockchain Development
NNT Software develops blockchain solutions such as audited smart contracts, supply-chain traceability, tamper-proof certificate verification, tokenised loyalty and permissioned ledgers on Ethereum-compatible chains and Hyperledger Fabric — and advises honestly when a conventional database is the better fit.
Hire Dedicated Developers
NNT Software lets companies in the USA, UK, Europe, the Middle East and Australia hire dedicated offshore developers from India on monthly contracts. You interview and select React, Node.js, Flutter, Python, .NET, Java, DevOps or QA engineers who work full-time on your product with daily time-zone overlap and free replacement.
API & Systems Integration
API integration connects separate software so data moves automatically. NNT Software builds reliable integrations between business systems and platforms such as Stripe, PayPal, Salesforce, HubSpot, QuickBooks, Xero, Shopify, Amazon, WhatsApp Business, Twilio and shipping carriers, plus custom REST and GraphQL APIs for partners.
Payment Gateway & PSP Integration
Payment gateway integration connects your checkout, app or platform to payment service providers so customers can pay by card, wallet or bank transfer. NNT Software integrates Stripe, Adyen, Checkout.com, PayPal and regional rails such as Pix, UPI, SEPA Instant and FedNow, with multi-PSP routing, payouts, 3DS2 and automated reconciliation.
Crypto Exchange Development
Crypto exchange development is building the trading platform, matching engine, wallets and compliance tooling that let users buy, sell and hold digital assets. NNT Software develops custom and white-label spot and P2P exchanges with liquidity integrations, hot/cold wallet architecture, KYC/AML and licence-ready reporting for regulated markets.
Crypto Wallet & Custody Development
NNT Software develops cryptocurrency wallets and custody infrastructure: non-custodial mobile and browser wallets, custodial wallets for exchanges and fintechs, and MPC or multisig custody with policy-based approvals for institutions, supporting Bitcoin, Ethereum, EVM chains, Solana and stablecoins.
Smart Contract Development & Audit
Smart contract development is writing self-executing code that runs on a blockchain. NNT Software builds and reviews Solidity and Rust smart contracts for tokens, DeFi protocols, NFTs, escrow and governance, with full test coverage, gas optimisation, static analysis and preparation for third-party audits.
DeFi & Asset Tokenization
NNT Software develops decentralised finance and tokenization platforms, including decentralised exchanges, lending and staking protocols, and real-world asset tokenization for real estate, funds and commodities with whitelisted, KYC-verified investor onboarding and on-chain cap tables.
