What Custom Software Fixes in Your Business

Eliminate Workflow Chaos

Disconnected tools and manual workarounds slow teams down. We build systems that streamline tasks, cut delays, and help teams work in sync.

Cut Human Error to a Minimum

Automated logic and clear interfaces reduce mistakes in critical operations — from data handling to approvals and reporting.

Build in Compliance from Day One

Forget spreadsheets and after-the-fact audits. We embed rules, permissions, and logs right into your software so compliance runs in the background.

See the Full Picture, Instantly

No more digging through multiple platforms. We connect systems into unified dashboards that show what’s happening — across operations, in real time.

Services We Provide

Digital Acceleration & Transformation

Digital isn’t a buzzword — it’s the baseline. We help businesses move from legacy tools to modern, scalable platforms that reduce manual work and enable new digital channels. Whether you’re launching a SaaS product, integrating with cloud systems, or moving operations online — our custom software development services connect your roadmap to real business outcomes.

Custom Product Engineering & Extension

We design, customize, and reengineer software that actually fits your operations. From refining off-the-shelf tools to extending internal systems with new modules, TwinCore helps companies adapt faster with clean, scalable code. This approach works across industries — retail, logistics, healthcare — wherever flexibility is a must.

Enterprise Process Automation

Manual work slows down decisions and drains budgets. Our custom solutions leverage APIs, workflow engines, and modern backends to automate approvals, data handling, dispatching, and more. We also build in support for RPA and AI models where needed — helping you cut delays, not just costs.

Web & Mobile App Development

We build fast, reliable applications — from logistics control panels to customer-facing mobile apps — with full backend/frontend logic, API integration, and performance optimization. Need a React-based SPA? A .NET backend? Native Android app? We’ve done it. And we maintain what we ship.

Cloud-Based Software Development

Get the most from AWS, Azure, or hybrid environments. Whether you’re building SaaS from scratch, migrating legacy systems, or architecting for high availability — we create cloud-native applications that are scalable, cost-efficient, and secure. Containerized, serverless, or distributed — we speak fluent cloud.

Data Analytics & Custom Dashboards

We turn raw data into real-time visibility. From tracking delivery delays to analyzing customer behavior — our custom analytics pipelines process, visualize, and report what matters. We build dashboards that connect data from APIs, databases, and cloud sources — and make it actionable.

Infrastructure Engineering & Scalability

Behind every smooth product is a rock-solid tech foundation. We help businesses build scalable systems, streamline backend logic, and set up reliable infrastructure — including distributed databases, caching, queueing systems, and monitoring. TwinCore ensures your system stays fast, stable, and ready to grow.

Software Strategy & Engineering Consulting

Need a second opinion before you build? We audit architecture, review codebases, and help you plan smart — from MVP scope to system design. Our software development consulting blends senior engineering with business thinking, so you don’t just ship — you ship right.

Legacy Software Modernization

Old systems don’t scale. We migrate outdated platforms to new tech stacks — whether that’s moving from WebForms to ASP.NET Core, replacing monoliths with microservices, or lifting to cloud-native. You keep business logic and data — we upgrade the foundation for speed, security, and future-proofing.

    FAQ


    How long does it usually take to build custom software?

    The duration of a custom software project can vary significantly. A basic application with limited functionality and no integrations may be completed within 2–3 months. For mid-sized business platforms or SaaS products with third-party APIs, the timeline ranges from 4 to 6 months. More complex solutions—such as enterprise-grade systems, data-heavy platforms, or multi-role user apps—may require 9 to 12+ months. We always begin with a discovery and architecture phase to accurately estimate delivery and align expectations from the start.


    Can you connect the software with our current systems or third-party tools?

    Yes, integrating your software with existing systems is often essential for workflow automation and data consistency. We support integration with ERPs, CRMs (like Salesforce or HubSpot), payment providers, logistics APIs, cloud storage platforms, and many others. Depending on your stack, we implement RESTful or SOAP APIs, webhooks, or direct database connectors. Before development, we assess compatibility, data format, and security implications to ensure stable, secure, and scalable integrations across your ecosystem.


    What factors affect the cost of custom software development?

    The main cost drivers are project complexity, feature set, integrations, technology stack, required compliance, and delivery speed. For example, apps with real-time processing, multiple user roles, advanced analytics, or strict security policies (like HIPAA or GDPR) require more engineering effort. The number of screens, API endpoints, testing scenarios, and third-party services also contribute. We provide detailed proposals after evaluating your needs and offer options for phased delivery or MVP-first to control budget without sacrificing long-term scalability.


    Can we stay involved during the development process?

    Yes—your level of involvement can be as active or hands-off as you prefer. Most clients choose to participate in sprint reviews, backlog prioritization, and feedback loops. We provide access to tools like Jira or ClickUp for tracking tasks and communication platforms like Slack or Teams for day-to-day updates. Weekly or bi-weekly check-ins ensure alignment, transparency, and the ability to pivot if your priorities evolve. You’ll never be in the dark—we believe in full visibility from start to finish.


    What’s the best model for working with TwinCore on custom software?

    We offer flexible engagement models based on your business needs. For clearly defined scopes, a fixed-price model ensures predictability. For evolving projects or startups, time & materials provides flexibility and faster iteration. Our most popular option—dedicated team—gives you full control over the roadmap and access to developers, QA, and a project manager who work exclusively on your product. This model is ideal for long-term partnerships where continuity, knowledge retention, and speed of delivery matter.


    How do you protect our business logic and IP?

    All custom code and intellectual property are legally assigned to you through our standard contract and NDA. We follow best practices in access control, versioning, and internal security audits. Sensitive business logic and architecture documentation are shared securely. We do not reuse or relicense any part of your project. Your data and proprietary features remain yours, fully and unconditionally.
