Your NetSuite can't do everything out of the box. I build what's missing.

Custom apps, portals, integrations, and AI solutions for companies running on NetSuite.

I'm Tim Dietrich. I've spent 25+ years building business software — the last 8 focused exclusively on NetSuite. If you need a customer portal, a custom checkout flow, a field service app, an API integration, or a practical AI-powered workflow, I can help.

How I help

Three ways to work with me — depending on what you need and where you are.

Custom Development

Need NetSuite to do something it wasn't designed to do?

I build the external applications that extend your NetSuite — customer portals, custom checkout flows, field service apps, Web APIs, webhook listeners, mobile tools, and third-party integrations. If NetSuite doesn't do it out of the box, I can probably build it.

AI Solutions

Want to put AI to work with your NetSuite data?

I help NetSuite teams move past the AI hype and find the practical applications — custom AI prompts, intelligent workflows, and tools tied to your actual data and processes. Not generic chatbots. Real solutions that save your team time and surface insights they'd otherwise miss.

Consulting

Need expert guidance on a specific NetSuite challenge?

60-minute sessions where you bring the questions and I bring the answers. SuiteQL optimization, integration architecture, identifying AI opportunities, or scoping a custom project. You get the recording, the clarity, and a concrete next step.

Open tools for the NetSuite community

I build tools that NetSuite developers and admins use daily.

SuiteQL Query Tool

A utility that lets you run SQL queries directly inside NetSuite. Used by NetSuite developers and administrators worldwide to explore data, debug issues, and build queries without leaving the platform.

SuiteAPI

A tool for working with NetSuite's REST APIs. Designed for developers who need to build integrations, test endpoints, and interact with NetSuite data programmatically.

How it works

I keep the process straightforward. No surprise scopes, no mystery timelines.

Tell me what you need

Describe the problem or the gap. A portal, an integration, an AI workflow — whatever NetSuite isn't handling for you.

I scope it and give you a straight answer

I'll tell you honestly whether I can help, what the approach would look like, and what it would take. No commitments until we're both clear.

I build it

I handle the design, development, and delivery. You stay informed throughout, but you don't need to manage the technical work.

You go live

You get a production-ready solution, documentation, and support through launch. No handoff into a void.

A bit of background

I've been building software professionally since 1998. For the last 8+ years, I've focused exclusively on NetSuite — building the custom external applications, integrations, and tools that companies need when out-of-the-box doesn't cut it.

Before that, I spent nearly two decades developing business software for organizations ranging from startups to Fortune 50 companies. I've built systems for the Library of Congress, Siemens, CarMax, the University of Virginia, Dominion Energy, and dozens of others across wholesale distribution, healthcare, manufacturing, financial services, and more.

I also built the SuiteQL Query Tool and SuiteAPI — open tools used by NetSuite developers and admins globally. And I've authored several books, including LinkedIn: Signal, Not Noise and FileMaker Pro 13 Absolute Beginner's Guide.

I work from Richmond, VA through my company, SuiteStep.
