What Microsoft Dynamics 365 Business Central developers typically cost in the US, and where that budget goes
If your ERP system feels like it's fighting you instead of helping you, you're not alone. Most business owners we talk to didn't set out to become ERP experts. They just wanted their finance, sales, and inventory data to live in one place instead of six spreadsheets and a prayer.
That's where Microsoft Dynamics 365 Business Central developers come in. They're the people who take a platform built for general use and shape it into something that fits your business specifically, not the other way around. If your company already feels like it's outgrown spreadsheets entirely, our piece on scaling past spreadsheets walks through exactly when that transition tends to happen.
This article covers what Microsoft Dynamics 365 Business Central developers do, what separates a strong one from a mediocre one, what tools they work in day to day, and how to think about cost and hiring before you sign anything.
Signs Your Business Needs Microsoft Dynamics 365 Business Central Developers Right Now
A few warning signs tend to show up before a business realizes it needs outside help.
Your team is exporting reports out of Business Central into Excel just to make them readable.
Someone is manually re-entering data between two systems that should already talk to each other.
A process that used to take an afternoon now eats up two full days every month end.
Approvals still route through email instead of a workflow the system could handle on its own.
None of these problems are dramatic on their own. That's exactly why they pile up. Each one is a small tax on your team's time, and each one is the kind of thing Microsoft Dynamics 365 Business Central developers are built to fix. If any of this sounds familiar, our breakdown of implementation best practices for small and mid-sized businesses is a useful gut check before you decide how deep the fix needs to go.

What Microsoft Dynamics 365 Business Central Developers Do Day to Day
The job title sounds narrow. The work is not.
Microsoft Dynamics 365 Business Central developers spend a good chunk of their time writing AL code, the language Microsoft built specifically for extending Business Central. That means creating custom tables, pages, reports, and codeunits that let the platform do things it can't do out of the box.
But writing code is only part of it. Microsoft Dynamics 365 Business Central developers also:
Build and maintain integrations between Business Central and your other systems. It's the same connective work we break down in connecting the dots your EHR can't, just applied to whatever platforms your business runs on
Debug issues that pop up after an update or a new customization
Migrate data from legacy systems, including older NAV or GP environments, a move that's become urgent for a lot of businesses since the clock is ticking on Dynamics GP end of life
Optimize performance when reports run slow or pages start lagging
Keep the system secure and compliant as your business grows
Document what they build so the next person, whether that's another developer or your own IT lead, isn't left guessing
A lot of that work happens quietly, in the background, long after the initial implementation is done. Business Central isn't a set-it-and-forget-it platform, and Microsoft Dynamics 365 Business Central developers know that better than anyone. Businesses that treat this as ongoing maintenance, rather than a one-time project, tend to get far more mileage out of their ERP investment over time.
6 Skills That Separate Strong Microsoft Dynamics 365 Business Central Developers From the Rest
Not every developer with "Business Central" on their resume can do this job well. Here's what to look for.
#1. Technical Depth in AL and C/AL
Anyone can follow a tutorial. A strong developer understands event-driven patterns, knows how to build extensions that survive future updates, and doesn't break your system every time Microsoft ships a new release.
#2. Business Process Fluency
The best Microsoft Dynamics 365 Business Central developers ask about your workflow before they touch a keyboard. On a manufacturing floor, that means understanding your bill of materials before writing a line of code, the kind of process work we cover in how to evaluate your options for manufacturing ERP software.
#3. Integration Experience
If your business relies on more than one platform, and most do, your developer needs real experience with APIs, OData, and web services. Distributors run into this constantly when connecting Business Central to a distribution management system that already handles warehousing or fulfillment.
#4. Communication that Doesn't Require a Translator
You shouldn't need a technical dictionary to understand what your developer is telling you. If every conversation ends in confusion, that's a red flag, not a personality quirk.
#5. A Track Record with Upgrades, not just Builds
Anyone can build something once. Fewer people can maintain it through three or four platform upgrades without it falling apart.
#6. Discipline Around Documentation and Version Control
Custom code that nobody wrote down becomes someone else's problem the day the original developer moves on. Strong developers treat documentation as part of the job, not an afterthought squeezed in at the end.
The Tools and Environment Microsoft Dynamics 365 Business Central Developers Work In
It helps to know what a real Business Central development setup looks like, if only so you can tell a serious operation from someone winging it.
Most Microsoft Dynamics 365 Business Central developers work in Visual Studio Code with the AL Language extension, which is Microsoft's official development environment for the platform. Extensions are built and tested in a sandbox environment first, separate from your live production data, so nothing gets pushed to your real system untested.
Version control plays as big a role here as it does in any other software discipline. Developers should commit their work to a system like Azure DevOps or GitHub, so changes are tracked, reversible, and reviewable before they ever touch your live environment. If a developer tells you they don't use version control, treat that as a serious red flag rather than a minor detail.
Testing typically happens in stages too.
A change gets built and verified in a sandbox, moved to a staging environment that mirrors production, and only then deployed live.
Skipping any of these stages is how small customizations turn into expensive outages. Microsoft Dynamics 365 Business Central developers who follow this discipline consistently are the ones whose work still holds up two or three platform upgrades later.
In House vs Partner: How to Access Microsoft Dynamics 365 Business Central Developers
This is usually where businesses get stuck. Do you hire your own Microsoft Dynamics 365 Business Central developers, or work with a partner who already has a team in place?
In-house hiring gives you full-time attention and someone who lives inside your systems every day. It also means salary, benefits, ongoing training, and the real risk that your one BC expert leaves and takes years of institutional knowledge with them.
Partnering with a Microsoft Solutions Partner gives you access to a full bench of Microsoft Dynamics 365 Business Central developers, functional consultants, and support staff, without carrying all of that overhead yourself. We laid out exactly what to look for in 7 things to know before choosing a Business Central partner, and how to compare options in our partner checklist for growing companies.
For most small and mid-sized businesses, a partner model is the more practical route. You get senior-level expertise on demand instead of betting your ERP stability on a single hire. It also means the work doesn't stall if one person is on vacation, changes roles, or leaves the field entirely, since a partner brings coverage that a solo hire simply cannot.
Businesses that have gone through this decision often land in the same place. Here's how one operations leader described working through it:
"Shannon has superior knowledge of Dynamics 365 and Business Central, her team and the clients of whom she works for. She was always available to answer questions or address issues during our implementation process. She helped us find talent for our own team and got the job done. She was a pleasure to have as part of our team during our company's implementation."
Beth, VP of Operations
What It Costs to Hire Microsoft Dynamics 365 Business Central Developers in the US
Let's talk numbers, since this is usually the question nobody wants to ask directly.
In-house Microsoft Dynamics 365 Business Central developers in the US typically start between $50,000 and $70,000 for entry-level roles.
According to a salary breakdown from Readynez, with average pay climbing to $90,000 to $110,000 as experience grows. Live job postings back up the senior end too.
A remote developer role listed through Jobot in New York was posted at $100,000 to $150,000.
Asenior remote openings through Nigel Frank ranged from $110,000 to $140,000. Add benefits, recruiting costs, and ramp-up time, and the real cost of an in-house hire climbs well past the base salary.
Partner-based engagements work differently. You're usually paying for a project scope or a block of hours rather than a full-time salary, so the cost scales with what you actually need done. We broke down real numbers in how much a Business Central implementation really costs, and licensing adds its own layer on top, covered in Business Central licensing and pricing explained.
Cost also varies quite a bit depending on who you hire. Offshore freelance developers may quote the lowest hourly rate, but time zone gaps and inconsistent documentation practices often eat into whatever you saved upfront. Boutique Business Central shops tend to sit in the middle, with more accountability than a lone freelancer and more flexibility than a large national firm. Enterprise-scale partners bring deep bench strength, but sometimes at a premium that smaller businesses don't need to pay for straightforward customization work.
Anyone who quotes you a number before understanding your business processes is guessing.
How to Evaluate Microsoft Dynamics 365 Business Central Developers Before You Sign a Contract
Before you commit to anyone, ask a few pointed questions.
Ask to see examples of extensions they've built, not just described.
Ask how they handle upgrades, since this is where a lot of custom code quietly breaks.
Ask what happens if the person you're working with leaves the project halfway through.
We put together a broader version of this line of questioning in 7 questions to ask before choosing an ERP consulting firm, and if you want the numbers side of that evaluation, 10 facts that help your hiring process is a good place to start.
A good developer, or a good partner, won't flinch at any of this. They'll have answers ready, because they've been asked before.
Common Mistakes Businesses Make When Hiring Microsoft Dynamics 365 Business Central Developers
A few patterns show up again and again.
Businesses hire based on price alone, then pay twice when the cheap customization breaks during the next update. They skip the discovery phase, letting a developer start building before anyone has mapped the workflow, a mistake we've seen derail otherwise solid projects, as covered in who should lead your ERP implementation. Others hit the same walls twice, the exact ones outlined in ERP implementation challenges and how guided self-implementation avoids them.
Some businesses also treat the first developer relationship as permanent, even after it stops working. If communication has broken down or the work has stalled for months, that's a sign to reevaluate, not a reason to wait it out. And a surprising number of businesses skip reference checks entirely, taking a portfolio at face value instead of calling a past client to ask how the relationship held up over time.
None of these mistakes are fatal on their own. But they compound quickly, and they're almost always avoidable with a little more upfront diligence.
