Moving from Dynamics GP to... Business Central vs Sage Intacct: Which Path is Right for Your GP Migration?

If you are a current Microsoft Dynamics GP user, you already know the headline: Microsoft is winding down support for GP. Your system will not stop working overnight, but the clock is running on updates, tax tables, and long term viability. This post breaks down the key differences between Microsoft Dynamics 365 Business Central and Sage Intacct for organizations shopping for their next platform after Dynamics GP.

Below we look at pricing, functional depth, ecosystem, and the drawbacks nobody puts on a slide. These two come up constantly on GP shortlists, and for very different reasons.

The GP Timeline You Need to Know

• April 1, 2025: New perpetual license sales to new customers ended
• April 1, 2026: New subscription license sales to new customers ended. Existing customers can still add users and modules
• December 31, 2029: End of product enhancements, regulatory and tax updates, service packs, and technical support
• April 30, 2031: End of security updates, and the end of subscription billing and SPLA use

There is still runway, but migration projects usually run 6 to 18 months. The conversations need to start now.

Microsoft Dynamics 365 Business Central

What It Is

Business Central is Microsoft's cloud ERP for small and mid sized businesses. It grew out of Dynamics NAV, a product that has been in the market since 1987, and it is where Microsoft is putting its mid market investment.

Why GP Users Like It

• Microsoft ecosystem integration: If your team lives in Microsoft 365, Teams, Outlook, and Power BI, Business Central sits inside that workflow rather than beside it
• Full ERP scope: Financials, purchasing, sales, inventory, warehousing, light manufacturing, and jobs all in one system, which matters if GP is running more than your GL
• Large partner network: Plenty of implementation partners, and a deep AppSource marketplace for the gaps
• AI capabilities: Copilot features are built in and expanding release over release
• Deployment flexibility: Cloud SaaS, on premises, or hybrid
• Familiar ISV relationships: Many of the add ons GP users already depend on, including AP automation, have Business Central versions, so tooling and vendor relationships can carry forward

Considerations

• Not an upgrade: Microsoft provides cloud migration tooling that moves master records and balances for organizations on GP 2015 or later, and the AIM program adds incentives and support. Even so, this is a new implementation with process redesign and testing, not a version update. Plan and budget accordingly
• Per user pricing: Costs scale with headcount. Essentials runs $80 per user per month, Premium $110, and Team Members $8
• Some GP functionality gaps: A handful of GP features still call for a third party solution in Business Central

Sage Intacct

What It Is

Sage Intacct is a cloud native financial management platform launched in 1999 as Intacct and acquired by Sage in 2017. It is deliberately not a full ERP. The product goes deep on accounting and reporting and leans on integrations for everything else. It is the only financial management application carrying an AICPA endorsement, which lands well with controllers and CPA firms.

Why GP Users Like It

• Dimensional accounting: Instead of stretching the account string to answer every question, transactions are tagged with dimensions like location, department, project, and customer. GP users who have spent years maintaining segment based charts of accounts tend to react strongly to this one
• Multi entity and consolidation: Real time consolidation across entities and currencies is core to the product rather than bolted on, which appeals to GP shops running a company database per entity and consolidating in Excel
• Reporting depth: Dashboards and financial report writing are built for accountants to own without developer help
• Vertical strength in services: Nonprofit fund accounting, SaaS revenue recognition, professional services project accounting, and healthcare are well established use cases
• True SaaS with automatic updates: Multi tenant, quarterly release cadence, no servers and no upgrade projects

Considerations

• Not a full ERP: Inventory is limited, and manufacturing and supply chain are not there. If GP is handling distribution, production, or serious warehouse activity, that work moves to a separate system connected by API
• No payroll in the core product: Payroll and HR come through add on modules or partner platforms, which is a real change for GP sites running US payroll in house
• Quote based, modular pricing: Sage does not publish a rate card. Quotes are built from a base subscription, named user licenses, and the modules you select. Partner and analyst reported ranges commonly land between $15,000 and $60,000 per year, with multi entity deployments and advanced modules pushing past $100,000. Individual add on modules frequently add several thousand dollars annually each
• Cloud only: No on premises or single tenant option, which rules it out for GP users with a hard requirement to keep the ledger in house
• Lighter Microsoft integration: Excel and Office connectivity exists, but the native Microsoft 365 and Power Platform tie in is not comparable to Business Central. The strongest native CRM pairing is Salesforce
• New ISV shortlist: GP add ons do not follow you. Every third party tool in your current stack has to be re sourced inside the Intacct marketplace

Quick Comparison

How to Decide

Business Central may be the better fit if:

• GP is doing more than accounting for you, and inventory, purchasing, or production need to stay in the same system
• Your organization runs on Microsoft 365 and Teams
• Predictable per user pricing suits how you budget
• You want the option of cloud, on premises, or hybrid
• Keeping current ISV relationships and AP automation tooling has real value
• Copilot and Power Platform are part of the plan

Sage Intacct may be the better fit if:

• Accounting sophistication is the whole point, and operations run in dedicated systems already
• You manage many legal entities and consolidation is currently a monthly spreadsheet exercise
• Your vertical is nonprofit, SaaS, professional services, or healthcare
• Dimensional reporting would replace a chart of accounts nobody wants to maintain
• Salesforce is your system of record for customers
• Your finance team wants to own reporting without IT in the loop

A Note on Accounts Payable

Whichever direction the evaluation goes, invoice processing deserves its own line in the plan. AP is usually the highest volume, most manual process in the building, and it is the first thing your team will notice on day one of the new system. Business Central keeps that path short, because AP automation built for Dynamics works on both sides of the migration. Fidesic supports Dynamics GP and Business Central today, so invoice capture, approval routing, and vendor payments do not have to be rebuilt from zero when the ERP changes underneath them. A move to Sage Intacct means selecting and implementing new AP tooling alongside the ERP project itself.

Conclusion

Business Central and Sage Intacct are both credible destinations for a GP organization, and the comparison is less about quality than about shape. Business Central is a full ERP with Microsoft gravity behind it. Sage Intacct is a specialist ledger with unusual depth in consolidation and reporting that expects the rest of your operation to live elsewhere. There is no universal answer. Team size, industry, entity count, existing technology, and what GP is actually doing for you today all move the needle.

The one thing that does not vary is the value of starting early. With support ending in 2029, the organizations that begin evaluating now will have better options, saner timelines, and calmer go lives than the ones that wait for the deadline to arrive.
