Hi!

I am completely new to D365, I have been working in Power Platform(canvas apps) and I want to learn about Dynamic 365.

In PowerApps, we develop apps from scratch, and integrate different tools like power automate etc

I am not able to understand why we have a variety of Apps in D365, I see Dynamics 365 Sales, Dynamics 365 Customer Service and many other Apps.

Could you please give me a brief on this? Why do we use these, when and if its already built what are we supposed to do as developers? Can we built anything from scratch?

Is there any documentation or video that you would suggest for me.

Your response to this would really help me learn. Thank you

Thats great you have already an understanding on Microsoft Power App which is part of Microsoft Power platform, and it will give you a great foundation

Unlike Power Apps, where you build solutions from scratch, Dynamics 365 is a suite of pre-built business applications designed for specific departments or roles. Each app solves a particular business need:

Dynamics 365 Sales use to Manage leads, opportunities, and pipelines
Dynamics 365 Customer Service use to Handle support cases, service requests
Dynamics 365 Marketing use to Run campaigns, manage customer journeys
Dynamics 365 Field Service use to Schedule and manage on-site service
Dynamics 365 Finance use to financial operations and reporting

These apps are built on the Dataverse platform, just like Power Apps — so they’re customizable and extensible.

What Do Developers Do in D365?
Even though the apps are pre-built, developers play a huge role:

Customize forms, views, and business logic
Extend functionality using plugins, Power Automate, and JavaScript
Integrate with other systems (e.g., ERP, external APIs)
Build custom apps using Power Apps and embed them into D365
Create custom tables/entities and model-driven apps
Yes, you can build from scratch especially using Power Apps (model-driven)

Dear Shravyashree_Shetty

Since you are new to D365, it’s important to align your learning path with your area of expertise.

If you have strong Business Analyst skills, you may consider D365 CRM or Sales.

If your background is in Accounting or Finance, then D365 Finance & Operations or D365 Business Central would be a good fit.

If you are inclined towards Data Science, you could focus on Microsoft Fabric, working with Power BI reports, data sources, and then advancing with Copilot and AI capabilities.

Hey,

I would suggest not overthinking this too much. First, decide which Dynamics 365 application you want to focus on—such as D365 Finance & Operations, CRM/CE, or Business Central. All of them have a strong market presence, so there’s no need to worry about demand.

If you already have skills in the Power Platform, I would recommend checking which ERP system has the largest market share in your region and start working with that.

If your organization is already using CRM/CE or Finance & Operations, talk to your lead or manager about your interest in learning and growing within the ERP space. This way, you can start gaining practical, hands-on experience, which is far more valuable than just learning from online sources alone.

As per your question. I don’t understand why Dynamics 365 has so many different apps. So the answer is below

Think of Dynamics 365 as a family of business applications rather than one single product. Microsoft designed it this way because different businesses have different needs—a retail store, a bank, and a manufacturing plant all run very different operations.

Here’s the breakdown:

D365 Finance & Operations (FinOps) – for managing finance, supply chain, manufacturing, and large-scale enterprise operations.

D365 Sales, Customer Service, Marketing, Field Service (CRM/CE) – for managing customer relationships, sales pipelines, support tickets, and service delivery.

D365 Business Central – a lighter, all-in-one ERP for small to mid-sized businesses, covering finance, sales, and inventory in one app.

D365 Human Resources – for HR processes, like hiring, employee records, and benefits.

D365 Project Operations – for managing project-based businesses (consulting, engineering, etc.).

D365 Commerce – for retail, e-commerce, and point-of-sale.

Microsoft built them separately so that companies can pick only what they need and integrate them as their business grows.

Hi @Shravyashree_Shetty

We build to extend, customise, and integrate these applications (and others) with other enterprise applications, depending on the requirements and business process of the customer.

The D365 fundamentals learning paths and exams are a good high level overview, you should start with those to give you some context about the eco system and how it relates.

Good luck and welcome!

Anthony
