Hey y’all. I’ve been working in Acumatica for 2 years now and have really gotten a handle on GIs, Import/Exports, Reports, Business Events, etc. 

Now I’m working through the T200 pdf training and my lack of web dev experience is making me have to dig far too deep into every code snippet to fully get it. My background is in Panorama Classic (a dead language) and Python, so I understand the basic structures of a language. However, I find myself constantly going, ‘but why?’ in the training in a way that I know means I’m NEARLY there. 

Do you know any videos or other tutorials that might help me get up to speed on doing my first solo customizations? 

Do you have advice for getting through these trainings from nearly zero?

Hi ​@lunarchickadee 
The Acumatica training materials-Acumatica Application Developer (PDFs) T200 etc.. are very well structured and provide a clear, step-by-step learning process. Even with basic C# knowledge, you should be able to complete the training successfully if your fundamentals are strong.

Before starting Acumatica customization, make sure you are comfortable with the following:

Minimum Skill Level Required

  • Writing C# classes without needing to look up basic syntax

  • Writing SQL queries confidently (SELECT, JOIN, GROUP BY)

  • Understanding how web applications work

C# Knowledge

  • Classes, inheritance, and interfaces

  • Delegates and events

  • LINQ

  • Generics

  • Basic understanding of ASP.NET (Web Forms concepts are helpful)

  • Basic understanding of DLLs

Database Knowledge

  • Microsoft SQL Server

  • Writing SELECT, JOIN, GROUP BY queries

  • Understanding database relationships (Primary Key / Foreign Key)

Tools You Should Be Familiar With

  • Visual Studio

  • SQL Server Management Studio (SSMS)

  • Acumatica Customization Project Editor

  • Basic IIS concepts

If you are comfortable with the above topics, you can confidently begin Acumatica customization training. Focus first on strengthening C# and SQL fundamentals if needed — that will make learning much smoother.

Hi ​@lunarchickadee,I believe Acumatica previously provided video tutorials for each course, but I’m currently unable to find them. However,  This will help you understand the customization process and how to work with customizations.

@lunarchickadee I had no development experience prior to working with Acumatica, and I went through an extensive C# course prior to working through the Acumatica developer training courses. 
That was really helpful for me since Acumatica backend development is essentially C# with a lot of custom platform APIs and conventions on top of it. Getting a good handle on C# really helped me understand what was just C#, and what was Acumatica specific. 

Beyond that, There is an Acumatica Developer GPT on ChatGPT that can be really helpful to answer questions about “Why this?”. 
It’s also super helpful if you can dig into the Acumatica source code and see how things are done there.

HI ​@lunarchickadee ,

You can view and follow the learning path provided by Acumatica. Since you are looking for T200, you can follow the ISV Partner Curriculum from the link below.

 Learning Paths

and for customization i also initially started learning with Acumatica Cloud ERP - Customizing Acumatica Part 1 

Hope above helps

That link goes nowhere for me. Do you have another one?

That’s pretty much where I landed in that I need to get my C# skills to a good place. And SQL is something I know the basics of, but could definitely use more training. Thanks for a really thorough answer.

Thank you so much for sharing. I didn’t want to feel like a C# course was going to be a bit too much to put myself through.
