Frequently Asked Questions About Custom Software at Netgen

Common questions about our custom software development services, technology stack, pricing, and process in South Africa.

Does Netgen build .NET enterprise systems?

Yes. Netgen is a .NET specialist with 25 years of experience building bespoke enterprise systems in C# .NET MVC and .NET Core with Microsoft SQL Server. We have delivered .NET applications for clients in manufacturing, healthcare, financial services, agriculture, and logistics, hosted on Microsoft Azure.

How much does custom software development cost in South Africa?

A typical engagement starts with a fixed-price scoping phase of around R38,000, after which the build cost is determined by scope. Most projects fall between R80,000 and R1,000,000+. You will know the price before the build begins, with no open-ended billing.

Who owns the source code after Netgen builds it?

You do. Netgen builds the software as your intellectual property. There are no software licence fees payable to Netgen, and you retain full ownership of source code, data, and the right to host or migrate the system anywhere.

Where are Netgen's offices in South Africa?

Netgen has offices in Johannesburg (Randburg, Gauteng) and Cape Town (Westlake, Western Cape). The company was founded in 2000 and works with clients across South Africa and internationally.

What technology stack does Netgen use for custom software?

Backend: C# .NET MVC, .NET Core, ASP.NET, SQL Server. Frontend: React, JavaScript, HTML5, CSS3. Mobile: React Native and .NET MAUI for iOS and Android. Cloud: Microsoft Azure. CMS: WordPress with custom themes and plugins.

Is Netgen B-BBEE compliant?

Yes. Netgen is a B-BBEE Level 2 contributor, which makes our services eligible for enhanced procurement recognition for South African clients with B-BBEE compliance requirements.

How long does a typical custom software project take?

Scoping takes 2 to 6 weeks. Build duration depends on scope, with most projects running 3 to 12 months in iterative agile sprints with regular client demos. Ongoing support and enhancements continue post-launch under a maintenance arrangement if required.
