Business Central Support vs. In-House Teams: Which One Actually Scales Your Business?

Here is a number worth sitting with: More than 70% of ERP initiatives fail to fully meet their original business goals, according to Gartner.

Business Central connects finance, operations, sales, and supply chain. But without the right support, even small issues escalate quickly. Orders get delayed, data falls out of sync, and visibility disappears.

Finance takes the biggest hit. Month-end close slips. Reports don’t reconcile. Leadership is left making decisions without reliable numbers. At that point, one question becomes critical. Who is responsible for keeping your system running?

 There are two answers. You either build an in-house ERP team, or you work with a certified Microsoft Dynamics 365 Business Central support partner. Both models can work. But for most SMBs and mid-market businesses in the ANZ region, one carries significantly more hidden cost and risk than people realise going in.

This post breaks down both models so you can decide before problems force it.

What Business Central Support Actually Involves

There is a common misconception worth clearing up. Microsoft does handle automatic updates for Microsoft Dynamics 365 Business Central.

What it does not handle is everything built on top of it: your customisations, your integrations, and your specific business workflows.

That’s where Business Central technical support comes in. In practice, it typically includes:

• Testing updates before they impact your system
• Resolving user and system issues
• Maintaining customisations and extensions
• Supporting integrations with other tools
• Monitoring performance and data accuracy

Business Central is not a set-it-and-forget-it system. It evolves continuously, and without ongoing support, small issues can turn into operational disruptions. The question is never really whether you need support. It is how you choose to deliver it.

The Case for an In-House ERP Team

Building an internal ERP team gives you direct control over your system and how it evolves. For some organizations, proximity can be a real advantage. But it also comes with trade-offs that are often underestimated.

Where it works in your favour

• Deep Process Understanding
  An internal team understands your workflows, reporting structures, and business nuances better than anyone external. This context helps in faster decision-making and more tailored solutions.
• Immediate Availability
  Teams can address day-to-day issues quickly without waiting for external response, especially for user queries or minor fixes.
• Institutional Knowledge
  Over time, internal teams build knowledge that stays within the organization, assuming strong retention and documentation practices.

Where the costs add up

• High and Ongoing Costs
  Hiring and maintaining ERP talent is expensive. Salaries, benefits, training, and recruitment costs can easily add $20K–$40K per employee annually on top of base compensation.
• Skill Gaps Across Areas
  Business Central requires expertise across finance, supply chain, integrations, and development. One or two hires rarely cover all areas effectively.
• Turnover Risk
  If a key team member leaves, critical knowledge goes with them. This can delay projects, upgrades, and issue resolution for months.
• Limited Scalability
  Internal teams are fixed in size. During upgrades, audits, or peak periods, they often struggle to keep up with increased demand.

The Case for a Microsoft Dynamics 365 Support Partner

Working with a Microsoft Dynamics 365 support partner provides specialised expertise without the overhead of building an internal team. For many businesses, this model offers flexibility, depth, and faster issue resolution.

What you get from day one

You are not waiting on a hire or a training cycle. You get immediate access to certified experts across finance, development, and integrations. Partners also bring cross-industry experience from multiple implementations, which means they have seen the problems you are likely to hit before you hit them.

Support scales with your needs. During upgrades or high-demand periods, coverage expands. When things stabilise, it scales back. You are not carrying fixed overhead through quiet periods.

The cost and accountability picture

 Compared to maintaining a full in-house team, Microsoft Dynamics 365 Business Central support through a partner typically reduces long-term total cost of ownership while improving coverage depth. SLA-backed response times mean issues are tracked, prioritised, and resolved within defined windows rather than sitting in someone's queue.

What to factor in

External partners need time to learn about your specific environment. A structured onboarding process and good documentation close that gap quickly, but it is worth factoring into your timeline. The model also works best when communication processes are clearly defined from the start. With the right structure in place, collaboration becomes reliable and efficient.

Side-by-Side: Business Central Support Partner vs. In-House Team

Factor	Business Central Support Partner	In-House Team
Time to respond	SLA-driven, structured, and consistent	Immediate, but limited by team availability
Cost structure	Flexible (retainer, project, or on-demand)	Fixed costs (salaries, benefits, training, overhead)
Expertise depth	Certified specialists across modules and use cases	Varies by hire; often limited coverage
Scalability	Easily scales up or down based on demand	Limited by team size and bandwidth
Knowledge Retention	Shared knowledge, documented processes	Knowledge tied to individuals
Access to updates	Built into Business Central technical support with ongoing optimization	Requires continuous internal training and effort

When an In-House Team Makes Sense

To be fair: there are scenarios where building internal capability is the right call. Specifically, it tends to make sense for:

• Large enterprises running highly customized Microsoft Dynamics 365 Business Central environments.
• Organizations with strong, existing expertise across Azure, Power Platform, and enterprise IT systems.
• Long-term, multi-module implementations where deep internal knowledge builds over time.
• Companies with the budget and structure to hire, train, and retain specialized Dynamics talent.

For most businesses, however, maintaining this level of capability internally can be resource-intensive and difficult to scale.

When a Microsoft D365 Support Partner is the Better Call

For most SMBs and mid-market organizations, a Microsoft Dynamics 365 support partner offers a more practical and scalable approach:

• You need Business Central support now, without delays for hiring or onboarding new staff.
• You are moving through an upgrade, migration, or expansion into new modules.
• Your support needs vary across the year, and a fixed internal team would be underutilised at times.
• You want certified expertise without the long-term overhead of employment.

 The right partner does not just keep the lights on. They help your system evolve as the business grows, improving performance, usability, and long-term value.

What to Look for in a Business Central Support Partner

Not all providers offer the same standard of support. When evaluating partners for Microsoft Dynamics 365 Business Central support, look for:

• Microsoft Solutions Partner designation (Business Applications) to ensure verified capabilities
• Proven experience with Business Central modules such as finance, supply chain, and manufacturing
• Clear SLAs with defined response and resolution times for reliable Business Central technical support
• Industry-specific experience so they understand your workflows and challenges
• Post-go-live services, including training, support, and continuous optimization
• Transparent pricing models, whether fixed, retainer-based, or on-demand

The strongest partner  bring both technical depth and a long-term perspective on how your ERP should grow with the business.

Final Thoughts

Both models have their place. An in-house team offers control and deep internal knowledge, while a Microsoft Dynamics 365 Business Central support partner brings flexibility, broader expertise, and faster response when it matters most.

For most SMBs, the maths favours the partner model. Better coverage, lower total cost, and no single point of failure when a key person walks out the door.

The businesses that scale Business Central well are the ones that treat support as a strategic decision, not an afterthought. They choose a model that fits their size, their growth trajectory, and their risk tolerance before a system issue forces the conversation.
