.NET Development for Manufacturers

Our .NET teams reduced manual operational effort by 40% for clients managing data across disconnected systems. .NET development for manufacturers is custom software on Microsoft's .NET 8 platform that connects OEE historians, quality databases, and ERP systems into tools your plant team will actually use.

Why manufacturers need custom .NET development right now

Manufacturing is under more data pressure than at any point in the past decade. Across the industries we serve, the pattern repeats: regulatory requirements are tightening while operational data fragments across disconnected systems. OSHA's 29 CFR 1904 electronic recordkeeping mandate means paper-based injury and illness logs are now a compliance liability, not just an inefficiency. EPA Title V air permit requirements increasingly expect digital, reportable data in near real-time. ISO 9001:2015 audits expect traceability from raw material intake to finished goods shipment.

The operational pressure is more immediate. Skilled labor shortages are pushing automation investments, but automation generates data your existing systems were not built to handle. OEE sits in a PLC historian. Quality events live in a shared Excel file. Work orders are on clipboards. Your Dynamics 365 or SAP instance holds part of the picture, not all of it.

ERP vendors will sell you modules for this. Those modules take 18 months to configure and often cost more than a purpose-built .NET application targeting your actual gaps. A focused .NET project integrates with your existing ERP rather than replacing it, and ships in 8-24 weeks.

What we build for manufacturing clients

The problems manufacturers bring to us fall into a few consistent patterns:

• OEE consolidation dashboards. We connect to PLC historians, SCADA systems, or existing MES via API or direct database integration. Plant managers see live downtime reason codes, shift performance, and trend data without manual compilation, typically eliminating 4-6 hours of Excel work per shift. Human-in-the-Loop (HITL) governance means a supervisor reviews automated downtime classifications before they feed into compliance reports.
• Digital quality management systems. We replace paper NCR (Non-Conformance Report) and inspection workflows with a .NET web application integrated with your ERP. FDA 21 CFR Part 11 and ISO 9001 audit trails are built into the data model from day one. HITL checkpoints require a named quality approver to sign off before any hold releases to the production floor.
• Supply chain visibility tools. Connected to SAP, Oracle EBS, or Microsoft Dynamics 365, these applications surface supplier lead times, open POs, and inventory positions in one view. Your purchasing team gets alerts before a shortage shuts down a line.
• EPA and OSHA reporting automation. We build scheduled jobs and report templates for EPA air emissions submissions, OSHA 300 log exports, and ISO documentation packages. Your EHS team stops spending Fridays in spreadsheets.

Every application ships with an API-first architecture, documented contracts, and a maintainable .NET 8 codebase your plant IT team can own.

How a .NET development engagement actually works (step by step)

Our standard manufacturing engagement runs 8-24 weeks. Here is the actual sequence:

1. Discovery (weeks 1-2). We interview your VP of Operations, Plant Manager, and at least two shift supervisors. We map the current data flow: what system owns what, where the manual steps are, what workarounds your team has built in Excel. We leave with a system map and a prioritized backlog.
2. Architecture and database design (weeks 2-3). We define the data model before writing application code. For manufacturing, this means designing the integration schema for SAP or Dynamics 365, defining a purpose-built SQL Server application database, and mapping every HITL checkpoint. We identify every decision point where a human must approve before data flows downstream.
3. Sprint development (weeks 3-16). Two-week sprints with a working demo at the end of each. Your plant team tests against real production data from sprint 3 onward. We use ASP.NET Core for APIs, Entity Framework for data access, and Azure App Service for cloud deployment, or on-prem Windows Server if your network policy requires it.
4. Integration and testing (weeks 14-20). We connect to your ERP, historian, or LIMS. Every integration is load-tested with realistic shift volumes. Compliance-sensitive fields get audit logging enabled from the first commit.
5. Go-live and handoff (weeks 20-24). Production deployment with a two-week parallel run. We train your plant IT team on the codebase and CI/CD pipeline. You own the code and the deployment pipeline; there is no vendor lock-in.

Smaller scopes (a single OEE module or a quality inspection form) compress this to 8-12 weeks. We do not pad timelines to hit a billing target.

What this costs

A .NET development project for a manufacturer typically runs between $40,000 and $250,000. The range reflects scope, not arbitrary pricing. See our full .NET development cost guide for a detailed breakdown by project type.

Drives cost up:

• Multiple ERP or MES integrations: add $3,000-$12,000 per non-trivial system
• Regulatory scope requiring FDA validation, EPA submission formats, or ISO documentation packages: add 15-25%
• Real-time data requirements (PLCs, SCADA, WebSocket streaming) versus batch reporting
• Multi-site deployments with site-specific configuration

Keeps cost down:

• Starting with one focused module (OEE or quality) instead of building a platform
• Clean existing data in SQL Server or a modern ERP
• API-first ERP configuration already in place

Our hourly rates run from $35 for standard .NET development to $65 for senior architects. Most manufacturing projects land in the 600-2,000 hour range ($30,000-$120,000), with ERP integration and regulatory overhead pushing larger engagements toward $150,000-$250,000.

Three things manufacturing buyers usually get wrong

1. Trying to build an ERP replacement instead of filling specific gaps.

The manufacturers who get the most value from custom .NET software stay focused. They identify two or three workflows where their ERP falls short and build exactly that. The manufacturers who struggle expand scope in discovery until a $60,000 project becomes a $400,000 one. We will tell you when the scope math stops making sense.

2. Skipping database design discipline because "we'll just use what SAP has."

Your SAP or Plex instance has been customized for years. Tables have columns nobody remembers the purpose of. Connecting directly to ERP tables without a clean integration schema creates brittle applications that break on every ERP upgrade. We always build a purpose-built application database with explicit ERP sync logic, documented before we write any application code.

3. Treating CI/CD as an IT luxury rather than a day-one requirement.

We have been called in to fix .NET manufacturing applications where deployment required a manual file copy to a server by whoever knew the password. When that person left, the application stopped getting updates. Automated deployment pipelines are not optional; they are how the application stays maintainable five years from now. We set up CI/CD in sprint 1, not as a post-launch project.

Recent work with similar clients

Our current .NET case studies are primarily in financial services and fintech, where we have delivered integration complexity similar to what manufacturing projects require. The common thread: consolidating fragmented operational data into a single .NET application that a non-technical team can actually use.

Our .NET fund manager desktop application reduced manual portfolio management effort by 40% by replacing disconnected spreadsheets with a unified real-time dashboard. The problem structure (multiple data sources, manual compilation, compliance reporting) maps directly to OEE consolidation and quality management in manufacturing.

We are actively building our manufacturing reference base. If you are a VP of Operations or Plant Manager open to being referenced (with NDA protection), contact us.

How long does .NET development take for a manufacturer?

A focused .NET module for manufacturing (one OEE dashboard or one digital quality form) takes 8-12 weeks from kickoff to go-live. A full operations platform integrating with SAP, Dynamics 365, or Plex and covering quality, OEE, and regulatory reporting runs 16-24 weeks. Timeline is driven by integration complexity and how clean your existing ERP data is, not by project size alone.
