Introduction to Microsoft Dynamics 365

Microsoft Dynamics 365 comes up a lot when a business starts to outgrow spreadsheets and a basic CRM. Sales wants one system, finance wants another, and someone suggests “just get Dynamics” because it does everything.

It does do a lot. That is both the appeal and the problem. This introduction covers what Dynamics 365 is, what is inside it, roughly what it costs, and whether a UK business of your size needs it.

What is Microsoft Dynamics 365?

Microsoft Dynamics 365 is a family of cloud business applications sold by Microsoft on subscription. It combines what used to be two separate products, Dynamics CRM (customer relationship management) and Dynamics AX (enterprise resource planning), into one set of apps that share the same data.

The important word is family. Dynamics 365 is not one piece of software you install. It is a collection of apps, each licensed separately, that you pick and mix. You might run just Sales. A larger business might run Sales, Customer Service, Finance and Supply Chain together.

Everything runs on Microsoft’s Azure cloud and plugs into Outlook, Teams, Excel and SharePoint. Power BI handles reporting, and Power Automate handles workflows between apps.

In practice that means your sales pipeline, customer records, invoices and stock levels can sit in one place instead of four. Less re-keying, fewer versions of the truth, and reports that do not need a Friday afternoon to build.

What is inside Dynamics 365?

Microsoft groups the apps into rough areas. Here are the ones most relevant to a small or mid-sized business.

Sales and marketing

Dynamics 365 Sales is the CRM. Leads, opportunities, pipeline, forecasts and quotes, with Outlook and Teams built in.
Dynamics 365 Customer Insights covers marketing automation: email journeys, segmentation and a single view of each customer.

Customer service

Dynamics 365 Customer Service handles support cases, knowledge bases and conversations across email, chat and phone.
Dynamics 365 Field Service schedules engineers, tracks parts and manages jobs on site.

Finance and operations

Dynamics 365 Business Central is the all-in-one ERP aimed at small and mid-sized companies. Accounting, invoicing, purchasing, stock and basic project management in one app. For most UK SMEs, this is the product you are actually choosing.
Dynamics 365 Finance and Supply Chain Management are the larger versions for multi-entity accounting or serious warehousing.
Dynamics 365 Commerce covers retail: point of sale, e-commerce and back office in one.

If you sell online through Shopify or WooCommerce, Business Central is the app you would most likely connect to your store. It syncs orders, customers and stock so your product pages show accurate availability. That matters for search as much as for customers, because product pages that sit out of stock for weeks lose rankings.

How much does Dynamics 365 cost?

Microsoft prices per user, per month, and the numbers change often. Check Microsoft’s current UK pricing before you budget. As a rough guide at the time of writing:

Business Central: roughly £55 to £60 per user per month for the standard tier, around £80 for Premium.
Sales: roughly £50 per user per month for Professional, £80 to £90 for Enterprise.
Customer Service: roughly £40 per user per month for Professional, £80 to £90 for Enterprise.
Field Service: roughly £80 to £90 per user per month.

Two things catch people out:

Implementation costs more than licences. Setting up Business Central for a 20-person business typically runs to several thousand pounds through a Microsoft partner, often far more.
Attach pricing. The first app is full price. Additional apps for the same user are discounted, so stacking apps is cheaper than the headline figures suggest.

For a 10-person business on Business Central, expect around £600 a month in licences plus a one-off setup bill. Compare that with what manual admin, missed follow-ups and stock errors cost you now. If the gap is not obvious, you are probably not ready.

Benefits for a UK small or mid-sized business

One system, one login. Sales, finance and operations share data. Fewer spreadsheets, fewer mistakes.
Familiar tools. If your team lives in Outlook, Excel and Teams, Dynamics feels like an extension of them.
Grows with you. Start with one app and add more later. You only pay for what you use.
Reporting you can trust. Power BI dashboards pull live data, so the numbers in the Monday meeting are actually from Monday.
UK compliance built in. Making Tax Digital VAT submissions and UK localisation are standard in Business Central.

The drawbacks

Be honest with yourself about these before you sign anything.

It is not plug and play. Every rollout needs configuration, data migration and training. Expect weeks, not days.
You will need a partner. Most SMEs do not have the in-house skills. Partner fees are a real, ongoing cost.
Overkill for micro businesses. With five staff and a simple product line, Xero plus a lightweight CRM will do the job for a fraction of the price.
Customisation has limits. Heavy customisation is expensive and complicates every future update.

Do you actually need it?

You probably need Dynamics 365 (usually Business Central) if:

You have outgrown Xero, Sage or QuickBooks and stock or projects are now painful to track.
Sales, finance and fulfilment are re-keying the same data into different systems.
You have 15 or more users who need the same customer and order records.
You sell through several channels and need one accurate stock figure across all of them.

You probably do not need it yet if:

A CRM like HubSpot or Pipedrive plus your accounting package already covers you.
Your main problem is getting more customers, not managing the ones you have.

That last point matters. Plenty of businesses look at ERP when the real bottleneck is that too few people can find them. If your website is not bringing in enquiries or orders, a new back-office system will not fix that. Sorting out the site and its search visibility usually comes first, and it costs a lot less than an ERP project.

Where LoudCrowd fits

We do not implement Dynamics 365. We build and market e-commerce sites on Shopify and WooCommerce, and we often work alongside businesses running Business Central behind the scenes.

If you are choosing a back-office system and want the website side to connect cleanly (stock levels, product feeds, order data), get in touch and we will tell you what to look for. No pitch.
