Business Central vs Great Plains

Table of Contents

Introduction

The debate over Microsoft Business Central vs Great Plains has intensified in 2026 because Microsoft itself has forced the issue. What was once a long-horizon planning conversation is now an active operational decision with hard deadlines attached.

Over decades, Microsoft Dynamics GP served as the backbone ERP for tens of thousands of small and mid-sized businesses across North America. Its Dexterity-based architecture, deep SQL Server integration, and native payroll module made it a trusted workhorse for finance, distribution, and operations teams.

The landscape has fundamentally shifted. The Dynamics 365 Business Central Vs Great Plains capability gap now widens with every release wave. The 2026 Release Wave 1 (version 28), which debuted in April 2026, delivered AI-driven agents, agentic ERP capabilities, and deep Power Platform integration none of which GP will ever receive.

Platform Snapshots: Dynamics 365 Business Central Vs Great Plains

Before going deep on the dynamics 365 business central vs great plains architecture debate, it helps to understand the foundational identity of each platform.

Microsoft Dynamics 365 Business Central:

Business Central is Microsoft’s strategic cloud ERP for small and mid-sized organizations. Built on the AL (Application Language) programming model and deployed natively on Microsoft Azure, it covers finance, supply chain, manufacturing, projects, and service operations from a single unified data model. It follows a biannual release cadence that ships features — not upgrades — directly into production environments.

As of the 2026 Release Wave 1 (v28), Business Central has moved decisively into what Microsoft calls ‘agentic ERP,’ meaning AI-powered agents that can autonomously execute multi-step business processes, not merely suggest actions. The platform is available in 180+ countries with built-in localization for local accounting standards, e-invoicing formats, and regulatory reporting in most major markets.

Microsoft Dynamics GP (Great Plains):

Dynamics GP is a client-server ERP built on Microsoft SQL Server and the Dexterity programming environment. Its architecture predates cloud computing, and while GP can be hosted in Azure using an IaaS model, it was never designed as a SaaS product. Updates are manual releases that require scheduling, downtime windows, and dedicated IT involvement.

The most recent substantive product update was released in 2022. GP version 18.7, released in October 2024, represents its final major code line. The platform is now in a maintenance posture with no planned feature innovation only regulatory compliance updates for existing customers through 2029.

Architecture Deep Dive: Cloud-Native vs. Client-Server Legacy

This is where technical teams must pay close attention. The architectural gap at the heart of the business central vs great plains comparison is not superficial — it fundamentally determines how each platform scales, integrates, and evolves.

Business Central Architecture:

  • Runtime and Extensibility: Business Central runs on the AL runtime with a web client, REST APIs, and OData feeds as first-class citizens. The platform exposes a rich set of APIs (both standard and custom) that integrate with any modern iPaaS solution, Azure Logic Apps, Power Automate, Zapier, or custom REST consumers. All customizations are packaged as extensions that run in isolation from the base application. Microsoft-managed updates deploy without breaking customer code. The 2026 Wave 1 introduced a unified management interface for PTEs and AppSource apps, reducing administrative overhead significantly.
  • Data Layer: Business Central stores data in Azure SQL, managed by Microsoft, with automatic backups, point-in-time restore, and geo-redundancy built into the SaaS contract. There is no customer responsibility for database patching, indexing maintenance, or SQL Server licensing.
  • MCP Server Access — New in v28: Version 28.0 introduces native MCP (Model Context Protocol) server access, enabling Business Central to participate directly in AI agent ecosystems. This positions BC as a data and process node within broader enterprise AI orchestration frameworks.

Dynamics GP Architecture

  • Runtime and Extensibility: GP runs on a three-tier client-server model: a Windows-based client, a middle-tier application server, and a Microsoft SQL Server backend. GP customizations are embedded directly into the application dictionary or deployed as Dexterity ‘chunks’ that are tightly coupled to the application version. Every GP upgrade requires re-testing and potentially re-developing all customizations. There is no REST API surface that matches BC’s native API coverage.
  • Data Layer: SQL Server databases are customer-managed, whether on-premises or hosted. Organizations bear responsibility for SQL Server licensing, backup strategies, index maintenance, and disaster recovery. The data model uses over 1,400 tables and relies heavily on stored procedures, making direct integration complex and fragile across version upgrades.

2026 Feature Currency: What's Shipping in BC vs. What's Static in GP

The innovation delta between these two platforms has never been wider. Here is a precise accounting of what Microsoft delivered in Business Central’s 2026 Release Wave 1 (v28), which went into production on April 1, 2026, compared to the feature state of Dynamics GP.

Business Central: 2026 Wave 1 Key Deliverables

  • Agentic AI and Copilot: Microsoft’s 2026 Wave 1 advances AI-powered agents that can autonomously handle sales and purchase scenarios from reading incoming customer inquiry emails to generating quotes and posting orders with minimal human input. Developers can now use AL to build custom agents, treating Microsoft’s default agents as extensible templates rather than fixed tools.
  • Invoice Matching Without Posted Receipts: Purchase invoice matching now supports matching invoice lines directly to purchase order lines without requiring a posted receipt — and the system can automatically post the receipt during invoicing. For high-volume procurement operations, this eliminates a persistent manual bottleneck.
  • Dimension Perspectives in Financial Reporting: With dimension perspectives, reports run once and produce the full dimensional breakout automatically, replacing workflows where finance teams ran the same report dozens of times per dimension. Lifecycle status (draft, approved, retired) adds governance to the report management process.

Additional Wave 1 Highlights

  • Supply Chain Flexibility: decoupled purchase order and inventory workflows for more adaptable fulfillment
  • Dataverse Field Mapping: map additional fields and custom tables from the UI without extensions or developer involvement
  • Scope 3 Emissions Tracking: full value chain tracking built into the financial and operational data model
  • Redesigned Outlook Integration: faster performance, Exchange-based email tracking, document attachment from Outlook
  • MCP Server Access: native AI agent orchestration participation (v28)
  • Extended Update Windows: administrators can schedule upgrade timing more flexibly

Dynamics GP: Feature State in 2026

There are no new features shipping for Dynamics GP in 2026. The product has been in a maintenance posture since 2022. Microsoft continues to issue regulatory compliance updates for existing modern-lifecycle customers, but no new business functionality, UI improvements, or integration investments are planned. All product innovation has been redirected to Business Central and Dynamics 365 Finance.

The Payroll Exception:

Dynamics GP retains a meaningful structural advantage with its full native payroll module W-2 processing, direct deposit, garnishments, tax filing built into the base application. Business Central does not include native payroll. Organizations must integrate with certified third-party providers via AppSource connectors. For most businesses, this is readily solvable. However, organizations with complex payroll requirements (multi-state, union, certified payroll for government contracting) must plan explicitly for this transition.

Dynamics GP vs Business Central Pricing, Licensing and Total Cost of Ownership

Understanding Dynamics GP vs Business Central pricing is one of the most common starting points for organizations evaluating the transition and one of the most frequently misunderstood. The published license cost for GP significantly understates the true TCO once infrastructure, talent, and compliance costs are factored in.

Business Central Licensing (April 2026):

Following Microsoft’s October 2025 price adjustment, current Business Central license tiers are:

License Type Monthly Cost (Per User) Included Functionality

Essentials

$80 / user / month

Finance, sales, purchasing, inventory, projects, basic warehousing

Premium

$110 / user / month

All Essentials plus manufacturing and service order management

Team Member

$8 / user / month

Read access, time and expense entry, limited write operations

Device License

$45 / device / month

Shared device scenarios such as warehouse terminals

Dynamics GP Licensing (Legacy Reference -- No New Sales After April 1, 2026):

License Type Cost Notes

Starter Pack (3 users)

$5,000 one-time perpetual + $900 annual enhancement

Existing customers only; no new instances available

Additional Full User

$3,000 one-time perpetual

Existing customers can add users to existing instances

SQL Server

Separate licensing required

Standard or Enterprise depending on user count

ISV Add-ons

Varies by module

HR, WMS, EDI, and other modules licensed separately

Total Cost of Ownership: The Full Dynamics GP vs Business Central Pricing Picture:

When organizations do a thorough Dynamics GP vs Business Central pricing analysis, the on-premises cost layers that do not appear on a GP license invoice consistently surprise finance teams:

TCO Component Business Central (SaaS) Dynamics GP (On-Prem / IaaS)

License Model

Predictable monthly subscription; includes all updates

Perpetual license + annual enhancement fee (20% yr 1, 18% after)

Infrastructure

None; included in SaaS subscription

Windows Server, SQL Server licensing, hardware or IaaS hosting

Database Administration

Microsoft-managed; no DBA cost

Customer DBA required for maintenance, indexing, backups

Security Patching

Included; Microsoft-managed

Customer-managed through 2031; then unsupported

Update / Upgrade Cost

No scheduled upgrade projects; updates auto-deploy

Manual upgrade projects required; cost rises with customization depth

Consulting / Talent Cost

Growing BC partner ecosystem; competitive rates

Shrinking GP talent pool; Dexterity expertise increasingly scarce and expensive

Compliance After 2029

Ongoing; Microsoft-managed regulatory updates

No regulatory updates; manual workarounds required for tax compliance

Innovation Value

Biannual feature releases included in subscription

No innovation; maintenance cost with declining value

Bridge to Cloud 3 (BTC3)

Microsoft migration incentive available for eligible GP customers

Not applicable

Bridge to the Cloud 3 (BTC3), launched January 1, 2026, provides financial benefits for eligible GP customers migrating to Business Central. Organizations that have not assessed their BTC3 eligibility are leaving meaningful migration credits on the table when making their business central vs great plains decision.

Security, Compliance and Governance

Security and Compliance Comparison Table:

Dimension Business Central Dynamics GP

Certifications

ISO 27001, SOC 2, GDPR, FedRAMP (US government)

Depends on customer-managed infrastructure configuration

Encryption

At rest and in transit; Microsoft-managed

Customer-managed; depends on SQL Server and OS configuration

Security Patching

Automatic; Microsoft-managed on release cadence

Manual; ends April 30, 2031

Access Control

Role-based access to field and table level; Azure AD integration

Role-based; SQL Server and Active Directory dependent; manual administration

Multi-Entity Compliance

Per-subsidiary security controls; v28 enhancements for subsidiary governance

Separate databases per entity; manual synchronization of permissions

Audit Trails

Built-in change log; Azure Monitor integration

Built-in audit trails; third-party tools often required for advanced logging

Data Residency

Azure region selection within SaaS; documented data residency

Azure region selection within SaaS; documented data residency

Penetration Testing

Microsoft-managed; part of Azure security posture

Customer-initiated; manual scheduling and cost

Extension Governance

Unified PTE/AppSource management with lifecycle controls (v28)

No centralized extension governance framework

For organizations in regulated industries healthcare, financial services, government contracting running an ERP platform that loses security patching by April 2031 creates a compliance exposure that audit committees and CISOs must address proactively. A late migration eliminates the option of a controlled, phased transition.

Migration Readiness: From GP to Business Central

This is not a data migration. It is an ERP transformation. That distinction matters for scoping, resourcing, and setting executive expectations accurately.

What Carries Over Well?

  • Chart of accounts (with dimensional remapping to BC’s dimensions model)
  • Open transactions: AP invoices, AR invoices, purchase orders, sales orders
  • Vendor and customer master data
  • Item and inventory master data
  • Historical transaction data (migrated to a read-only archive or reporting warehouse)

What Requires Re-Architecture?

  • GP customizations built in Dexterity must be rebuilt as BC extensions in AL — there is no automated migration path
  • Report layouts (Management Reporter, Crystal Reports, SSRS) must be rebuilt in BC’s Word/Excel/Power BI framework
  • Integrations built on eConnect or direct SQL must be rebuilt against BC’s REST API surface
  • Payroll processes must be mapped to a certified third-party payroll ISV integration
  • User roles and permission sets must be redesigned from scratch in BC’s security model

Recommended Migration Phases:

Phase Activities Typical Duration

Phase 1: Discovery and Assessment

Map GP usage, identify customizations and integrations, assess BTC3 eligibility, define go-live scope

4 to 8 weeks

Phase 2: Design and Configuration

Configure BC for finance and COA, design dimension structure, build extension requirements, design integration architecture

6 to 12 weeks

Phase 3: Data Migration and Testing

Migrate master data and open transactions, parallel ledger validation, user acceptance testing

4 to 8 weeks

Phase 4: Go-Live and Stabilization

Cutover, hypercare support, post-go-live optimization and training reinforcement

2 to 4 weeks

Total timeline for a mid-market organization (100-300 users, moderate customization): typically 6 to 12 months from kickoff to go-live.

Decision Matrix: Which Platform Fits Which Organization?

Scenario Recommended Path

Current GP customer, no migration plan

Begin BTC3 eligibility assessment immediately. Start Phase 1 discovery no later than Q3 2026.

Current GP customer, heavily customized

Prioritize customization audit in discovery. Plan for 12+ month migration timeline with parallel operations.

Evaluating a new ERP, SMB under 250 users

Business Central Essentials or Premium. GP is unavailable for new customers as of April 2026.

Need native payroll, no third-party integration

Evaluate existing GP (current customers only) or carefully assess certified payroll ISVs for BC.

Multi-entity or international operations

Business Central. GP’s multi-entity architecture creates significant reporting complexity at scale.

AI or Copilot is a strategic priority

Business Central exclusively. GP has no AI capability or roadmap.

Manufacturing-intensive operations

Business Central Premium. Full routing, machine center, and production order capabilities included.

Strong Microsoft 365 or Teams dependency

Business Central. Native Microsoft 365 ecosystem integration is a core differentiator.

GP on-premises, concerned about 2029 compliance

Migrate to Business Central SaaS. Begin scoping now to avoid compressed timelines and higher costs.

Regulated industry (healthcare, financial services, government)

Migrate proactively. Security patching ends April 2031; audit exposure grows every quarter of delay.

Frequently Asked Questions

We are on Dynamics GP and our support ends in 2029. Can we just stay on GP until the last possible date?

Technically, GP will continue to function after December 31, 2029. Software does not self-destruct. However, after that date, your organization will receive no tax table updates, no regulatory compliance fixes, no service packs, and no technical support from Microsoft. Running payroll or closing your fiscal year on unsupported tax logic creates real compliance risk. After April 30, 2031, security patches cease entirely, making GP a security liability for any organization in a regulated environment. As the GP talent pool continues to shrink, emergency consulting costs for break-fix scenarios will escalate sharply.

Staying on GP until the final date is viable only for organizations with a concrete plan to divest, wind down, or merge. For everyone else, the business central vs great plains decision is not a matter of if — only when.

Is Business Central a true replacement for Dynamics GP, or will we lose functionality?

For most GP customers, Business Central matches or exceeds GP’s functional coverage across finance, supply chain, and operations — with the significant exception of native payroll. BC’s dimensional accounting model is more flexible than GP’s fixed account segment architecture. Reporting capabilities, particularly with Power BI and the 2026 Wave 1 improvements, exceed what Management Reporter delivers. Where GP has depth — particularly its native payroll module and some niche manufacturing configurations — these gaps are addressed through certified AppSource ISV solutions.

When evaluating microsoft business central vs great plains functionally, BC comes out ahead in every dimension except native payroll. The transition is an ERP transformation, not a feature downgrade.

What does Dynamics GP vs Business Central pricing actually look like when total cost is factored in?

The Dynamics GP vs Business Central pricing comparison looks very different once infrastructure costs are included. GP’s published perpetual license cost does not account for SQL Server licensing, Windows Server infrastructure, dedicated DBA time, manual upgrade project costs, rising Dexterity consulting rates, and third-party payroll update subscriptions. When aggregated, many organizations find that Business Central’s SaaS subscription is cost-competitive with their current GP operational spend — before factoring in the innovation value Business Central delivers in every release wave. Organizations should also assess BTC3 eligibility, which can reduce Business Central licensing costs materially during the initial subscription period.

Can we run Business Central on-premises to maintain control over our data?

Yes, Business Central offers an on-premises deployment option. However, the on-premises version does not include Microsoft Copilot, AI agents, or automatic update capabilities. Organizations choosing on-premises BC trade the innovation and operational efficiency of the SaaS model for greater infrastructure control. For most SMB and mid-market organizations, the SaaS model delivers a superior risk/reward profile. Regulated industries with specific data residency requirements should evaluate Microsoft’s Azure region selection options within the SaaS model before defaulting to on-premises deployment.
