Services

Enterprise .NET Capabilities We Provide

From a single departmental tool to a company-wide, multi-region platform, delivered by architects who have built enterprise scale before, not learned it on your project.

01

Enterprise Architecture and System Design

Domain-driven design, CQRS, and event-driven architecture patterns for .NET systems that need to scale across departments, regions, and years of feature growth without a rewrite.

Deep integration with the ERP, CRM, payment, and logistics systems your enterprise already runs on, built to reduce integration cost rather than force a rip-and-replace.

03

Enterprise Security and Access Control

Role-based access control, single sign-on, audit logging, and encryption architecture built for organizations where a security gap is not an inconvenience, it is a liability.

Azure and AWS deployment architecture built for high availability, disaster recovery, and multi-region operation, with DevOps pipelines your internal team can operate independently after handoff.

05

Microservices for Enterprise Scale

Breaking a monolithic enterprise .NET system into independently deployable services where team size and release cadence genuinely justify the added operational complexity. Covered in depth on our Microservices Development page.

Incremental migration from legacy .NET Framework or monolithic architecture to modern, cloud-native .NET, preserving business logic while the business keeps running. Covered in depth on our .NET Migration and Modernization page.

Compliance

US Compliance Built Into Enterprise .NET Architecture

Enterprise systems carry more regulatory surface area than a single application, since they typically touch more data types, more user roles, and more states. Compliance work and legacy data migration routinely add 30 to 50 percent to a base enterprise build, and we scope that honestly from discovery.

HIPAA

PHI across multi-facility healthcare enterprises

Encrypted storage, role-based access at enterprise scale, full audit logging across every facility or practice, and BAA-compliant data flows built into the enterprise architecture from the first sprint.

SOC 2

Security, availability, confidentiality for enterprise SaaS vendors

Enterprise-grade access controls, audit logging across every tenant, availability monitoring, and incident response architecture built to withstand a SOC 2 audit at scale.

PCI-DSS

Card payment data at any enterprise processing transactions

Tokenized payment flows and PCI-scoped network segmentation designed into the enterprise application layer across every business unit that touches payment data.

Multi-State Privacy Law

CCPA/CPRA, NY SHIELD, BIPA, TDPSA, MHMDA, and more, across an enterprise's full user base

Consent management, opt-out workflows, biometric consent, and data subject request handling mapped to every state an enterprise actually operates in, not a single generic privacy policy applied everywhere.

Engagement Models

Three Ways to Engage Our Enterprise .NET Team

Most enterprise .NET vendors will not give you numbers before a sales call. Here they are up front.

01

Milestone-Based Fixed Project

Best for: a defined enterprise platform with a clear scope and delivery date

Full architecture, milestones, timeline, and total cost agreed before development starts. Progress and spend visible at every milestone, not just at the end.

From $150,000

02 ★ RECOMMENDED

Dedicated Enterprise Team

Best for: ongoing enterprise platform development and multi-year roadmaps

A dedicated team embeds into your organization as a permanent engineering extension, full codebase ownership, architecture depth that compounds across years, not projects. Scoped to your team size

03

Enterprise Staff Augmentation

Best for: enterprise teams with a specific architecture or delivery gap

Senior enterprise .NET architects and developers placed inside your existing team, augmenting large in-house engineering functions without permanent headcount risk.

Flexible, engagement based rates

Why Digisoft Solution

Why Enterprises Choose Digisoft Solution

ScienceSoft, Sigma Software, N-ix, Leobit, Coherent Solutions, and Radixweb all compete for enterprise .NET contracts, most quoting custom pricing only after a discovery call. Here is what actually sets Digisoft apart.

800+Projects Delivered

Real Cost Tiers Published Up Front

Most enterprise .NET vendors will not discuss numbers until after a sales call. We publish our own cost tiers, small-scale ERP from 80,000 dollars, mid-market from 200,000 dollars, company-wide platforms from 600,000 dollars, so you can scope realistically before the first conversation.

Architecture Reviewed Before a Single Line of Code

Enterprise .NET failures usually trace back to architecture decisions made in the first three weeks, not code quality later. Our architects define system structure, data model, and integration points, and get it reviewed by your team, before development begins.

One Accountable Team, Not a Chain of Subcontractors

Enterprise platforms fail when discovery, architecture, delivery, and support sit with different vendors billing for the gaps between them. Digisoft delivers architecture through post-launch support as one coordinated team.

Compliance and Legacy Migration Costed Honestly

Compliance work and legacy data migration typically add 30 to 50 percent to a base enterprise build. We scope that reality into the estimate from day one instead of discovering it as a change order mid-project.

Milestone-Based Delivery, Not a Black Box

Every enterprise engagement is broken into milestones with agreed deliverables and costs. You see progress and control spend at each stage, not just at project completion.

Senior Engineers Who Have Built Enterprise Scale Before

Our .NET architects have delivered credentialing platforms, insurance SaaS, and civic intelligence systems at production scale for US enterprise clients, not learned enterprise architecture on your project.

Process

How We Deliver Your Enterprise .NET Platform

Enterprise .NET projects fail on architecture decisions made in the first three weeks, not on code quality later. Seven steps, here is how we prevent that.

Discovery and Enterprise Compliance Mapping

2 to 3 weeks. We map every existing system, integration dependency, user role, and the specific compliance obligations that apply across your full enterprise footprint. HIPAA, SOC 2, PCI-DSS, and relevant state privacy law scoped honestly, including the 30 to 50 percent compliance and migration overhead most vendors leave out of the initial quote.

Enterprise Architecture and Milestone Planning

2 to 3 weeks. Our architects define system structure, data model, integration architecture, and security approach, broken into milestones with agreed deliverables and costs at each stage, reviewed by your team before development begins.

UI/UX Design at Enterprise Scale

3 to 5 weeks. Every screen and role-based view designed and approved before development starts, accounting for the range of user roles, admin, manager, end user, support, finance, an enterprise system typically requires.

Agile Delivery Across Milestones

Varies by scope, typically 4 to 9 months. Two week sprints within each agreed milestone. Working, reviewable software deployed to staging at each sprint end, with progress and spend visible at every stage, not just at project completion.

Enterprise QA and Security Testing

Parallel with development. Unit, integration, load, and security testing at enterprise scale, including multi-tenant isolation testing and compliance verification integrated from sprint one.

Production Deployment and DevOps Handoff

1 to 3 weeks. Production deployment with full CI/CD pipeline, monitoring, disaster recovery configuration, and runbook documentation, so your internal team can operate the platform independently.

Post-Launch Support and Enterprise Scaling

Ongoing. Ongoing maintenance, security patching, and continued feature development as your enterprise platform scales to more users, more regions, or more integrations.

What We Build

What Enterprise .NET Development Costs and Includes

Enterprise .NET development spans a wide range depending on scope. An internal departmental tool runs 50,000 to 150,000 dollars. A core business platform, an ERP, CRM, or operations hub replacing 6 or more disconnected systems, runs 150,000 to 500,000 dollars. A compliance-heavy system with HIPAA, SOC 2, or multi-region requirements, and legacy data migration, runs 300,000 dollars to over 1,000,000. Company-wide platforms with complex integrations and global deployment can run 600,000 to 2,000,000 dollars.

01

Custom ERP and CRM Development

Replace disconnected point solutions with one system built around your actual workflow

Standard ERP and CRM products force your operations to fit their workflow. We build .NET based ERP and CRM systems around how your business actually runs, consolidating finance, HR, inventory, supply chain, and service delivery data that currently lives in 6 or more disconnected systems into one source of truth.

Best for: organizations where off-the-shelf ERP or CRM products create more workarounds than they solve

02

Multi-System Integration and Operations Hubs

One platform consolidating data from across the organization

Enterprise .NET platforms that connect payment gateways, HR systems, logistics providers, and analytics tools via REST or GraphQL APIs, giving a 200-person or larger team one dependable view of what is actually happening across the business.

Best for: organizations where the single source of truth problem is costing real time and real money

03

Compliance-Heavy Enterprise Systems

HIPAA, SOC 2, PCI-DSS, and multi-state regulatory requirements built into the architecture

Enterprise systems that touch protected health information, payment data, or regulated industries need compliance architecture from day one, not retrofitted before an audit. Compliance work and legacy data migration typically add 30 to 50 percent to a base enterprise build, and we scope that reality up front rather than discovering it mid-project.

Best for: healthcare, fintech, and public sector organizations with named regulatory requirements

04

Legacy Enterprise System Modernization

Migrate aging .NET Framework or monolithic systems without a risky full rewrite

Enterprise .NET systems built on ASP.NET Framework 4.x or aging monolithic architecture that has become expensive to maintain and impossible to extend. Covered in full depth on our dedicated .NET Migration and Modernization Services page, with incremental migration patterns that keep the business running throughout.

Best for: organizations running critical operations on .NET systems built 8 or more years ago, see the dedicated Migration page for depth

FAQs

Frequently Asked Questions

Answers written for Google Featured Snippets, People Also Ask, and AI Overview citations.

Enterprise .NET development is building large-scale software on Microsoft's .NET platform for organizations with complex, multi-system operations: custom ERP and CRM systems, operations hubs consolidating data from multiple sources, and platforms that need to serve hundreds or thousands of users across departments or regions, rather than a single team or workflow.

Enterprise .NET development typically costs 50,000 to 150,000 dollars for an internal departmental tool, 150,000 to 500,000 dollars for a core business platform like an ERP, CRM, or operations hub, and 300,000 dollars to over 1,000,000 for compliance-heavy systems with legacy data migration. Company-wide platforms with complex integrations and global deployment can run 600,000 to 2,000,000 dollars. Digisoft Solution provides a detailed written scope and cost breakdown after a free discovery call.

Compliance work and legacy data migration routinely add 30 to 50 percent to a base enterprise build cost, because HIPAA, SOC 2, or multi-state privacy requirements affect the data model, access control architecture, and audit logging throughout the system, not just a single feature. Vendors that quote low upfront and add compliance costs later are usually leaving this out of the initial estimate, not avoiding it.

It depends on how well your operations fit a standard workflow. Off-the-shelf ERP and CRM products work well when your business processes are fairly standard. A custom .NET ERP or CRM makes sense when standard products force enough workarounds that the workarounds themselves become a maintenance burden, or when you are consolidating 6 or more disconnected systems into one source of truth.

A departmental tool typically takes 8 to 20 weeks. A core business platform, ERP, CRM, or operations hub, typically takes 4 to 9 months with a 6 to 10 person team. Large-scale, multi-region enterprise platforms can take 12 to 24 months. Timeline depends primarily on integration count, user scale, and compliance scope, which is why we map these in detail during discovery before committing to a date.

Enterprise .NET work requires architects who have handled multi-tenant data isolation, compliance architecture across multiple regulatory frameworks, and integration with legacy systems at scale before, not general web development experience applied to a bigger project. Ask any vendor for named enterprise clients and specific system scale, number of users, number of integrations, before signing.
