Where to start with Dynamics 365 Business Central

This station opens with a separation rather than an ordering, because the commonest error on this path is made before the first screen is opened, and its price is months of study in the wrong direction.

The two products whose names resemble each other

	Business Central	Dynamics 365 Finance & Operations
Target size	Small and mid-sized	Large and enterprise
Code base	Navision, in AL	Axapta, in X++
The certification	MB-800	MB-310, MB-330 and others
Licensing logic	Per user, at a published price	A minimum commitment and different terms

Two different code bases, two different product teams, two different job markets.

Confusing them costs twice: once when a company is sold the wrong tier, and once when a jobseeker studies for the wrong exam — and the second is the one that concerns you now.

So verify the exam code before you buy a book or book a slot. The code that concerns you is MB-800 and nothing else.

Where it came from — an explanation, not a history

The system is Danish in origin and American in ownership. It began in Denmark as Navision, Microsoft bought it in July 2002 for $1.45 billion — the first billion-dollar foreign acquisition in the company’s history — where it became Dynamics NAV, and it was then rebuilt for the cloud and released as Business Central in April 2018.

Three things are explained by that paragraph alone:

One: its accounting depth is European in origin. Its European localisations run deeper than anybody reading the Microsoft name on it would expect, and its localisations in our region are far weaker — for that same reason and no other.

Two: its concepts are not Microsoft inventions. The posting matrix, the number series and the dimensions all come from the Navision inheritance. Anyone reading old material about the predecessor system is reading concepts that are still correct and screens that are not.

Three: its rhythm is mandatory cloud. Two waves a year on a date the developer sets. There is no customer base stranded on an eight-year-old release as happens with other products — a real gain, with a price explained at station eight.

The first decision: functional or technical

	The functional track	The technical track
What you do	Analyse the client’s process and configure it in the system	Build extensions, integrations and reports
What you master	Accounting, the posting matrix, configuration	The AL language, the development environment, the APIs
Who you sit with	Accountants, buyers and managers	Programmers and systems administrators
How your success is measured	A project delivered and used	An extension that survives both update waves
The certification	MB-800	MB-800, then the developer exams

The last row carries this product’s peculiarity: even the technical track starts at MB-800. The extension you write posts to the ledgers, and anyone who does not understand the posting matrix builds an extension producing entries they cannot defend.

The rule everybody who has worked on this product repeats: functional comes before technical, always.

The second decision: read your market by counting

Counting here differs from every other product on this site, because one extra question is asked.

Do this in one hour:

1. Count the job adverts naming the product explicitly in your country over one month, and separate those saying Business Central from those saying Finance & Operations. The two numbers are different, and confusing them is exactly the error this station opened on.
2. Open three partners’ pages in your country, and look on each for two words: Arabic, and tax. Whoever names them and names the publisher of the app knows what they are selling; whoever mentions them as a promise does not.
3. Count the companies you know that already run Microsoft 365, because that is this product’s natural base, and most of its clients come from it.

Never repeat a number you did not count. The number you end up with may tell you the demand in your country is for the other product, which is a useful result rather than a negative one — one hour saves two months.

Who the product suits — because it tells you where you will work

The practical range is from five users to about three hundred, at a company that already lives inside Microsoft 365.

That last condition is the strongest argument for choosing it at all: a finance team working in spreadsheets and email all day has bought half the training in advance, because exporting, editing and publishing back is native to the product rather than a bridge bolted onto it.

Read that paragraph as a map of your future clients. Whoever knows where the product fits knows where to look for work — and where not to.

The cases it does not suit, the first of them a requirement for an Arabic interface, are set out in the Dynamics 365 Business Central guide.

The honest time estimate

• 15 hours to run a full purchase and sales cycle and read their entries.
• 40 hours to configure the posting matrix and use it to diagnose an entry that went to an unexpected account.
• 70 to 110 hours to reach certification standard.

Those are shorter than their equivalents elsewhere on this site, and the reason is not that the product is simpler; the reason is that the environment and the material are free.

The order I recommend inside the path

1. Accounting basics first. The posting matrix is not understood without understanding the entry.
2. The document cycle and each step’s effect on the ledgers.
3. The posting matrix and dimensions — what distinguishes this product conceptually.
4. Financial reports with account schedules — the fastest skill that makes you useful here.
5. The AL language and the development environment — for the technical track alone, and after the four above rather than before them.

The mistake that stops half of all beginners

Rushing to open the development environment.

The ease of reaching the tools here tempts people to start from code, and then the first interview question arrives — always about the accounting effect rather than a line of code — and it becomes clear the candidate writes into a system whose ledgers they do not understand.

The alternative: start from the entry. Ask of every document: what does it do to the ledgers, and where did the account come from? The second question is the whole door into station three.

The acceptance test for this station

1. Write in three lines the difference between the two similarly named products, and the exam code that concerns you.
2. Choose your track — functional or technical — with a single sentence of reason, and write why both start at the same exam.
3. Count your country’s job adverts over one month, separated between the two products, and record both figures with their date.
4. Open three partner pages and record who named Arabic and tax by name rather than by promise.
5. Write a credit purchase entry and a credit sale entry from memory. If you stumble, that is your real station before station two.

What comes next

You have decided your track and read your market. The next station is the easiest on this entire site: a real training environment — free, with complete company data working from the first moment — and we will use it the same day rather than a month later.
