Web application development
Responsive, high-performance business applications, customer and agent portals, and internal tools built with modern frameworks.
Custom Software Engineering
Custom application development for the enterprise
Secure, scalable web, cloud and mobile applications engineered around the way your business actually works — and integrated cleanly with the systems you already rely on.
Overview
Software that fits your business instead of forcing workarounds
Off-the-shelf products get you most of the way — but the processes that differentiate your organization often live in spreadsheets, email threads and aging in-house systems. Custom applications close that gap, automating complex workflows and giving customers, partners and employees the experience they expect.
EntiSolve designs and builds custom applications end-to-end: from product discovery and UX through architecture, development, testing, deployment and support. Our senior engineers favor proven, supportable technologies, modern DevOps practices and clean, documented code that your team can own with confidence.

FAQ
Custom Application Development FAQ
How much does custom application development cost?
Cost depends on scope, complexity, integrations and timeline. After a short discovery we provide a detailed estimate and can deliver as a fixed-price project for well-defined scopes or as time-and-materials for evolving products.
How long does it take to build a custom application?
A focused minimum viable product often takes 8 to 16 weeks, while larger enterprise platforms are delivered in phases. We prioritize getting a valuable first release into users' hands quickly.
Who owns the source code?
You do. Unless agreed otherwise, all source code, documentation and deliverables created for your project belong to your organization.
Can you modernize an existing legacy application?
Yes. We assess the current system and recommend the lowest-risk path — refactoring, re-platforming to the cloud or incremental replacement — while keeping the business running.
Can you integrate the application with our existing systems?
Yes. Integration is one of our strengths. We connect applications to CRM, ERP, policy administration, identity providers, communications platforms like Smart Communications and custom databases.
