Dynamics GP replacement planned on Microsoft's real dates, not a sales deadline.
An independent assessment of where your GP should go - Business Central, Acumatica, Sage Intacct, or a custom build for the workflows no package covers - followed by a fixed-price data migration with every module reconciled before cut-over.

In short
Agenbord Migrate for Dynamics GP is a fixed-scope service for organizations planning their move off Microsoft Dynamics GP before product and tax updates end on December 31, 2029. We inventory your modules, customizations and integrations, compare Business Central, Acumatica, Sage Intacct and a custom option fairly, then migrate and reconcile your data. It is an independent service with published price bands; we are not a Microsoft partner.
What slows microsoft dynamics gp users down today.
Deadlines are close enough to plan, far enough to stall
Security updates run to April 30, 2031, so it feels like there's time. But tax updates and support end December 31, 2029, a good ERP selection and migration takes 9–18 months, and every year-end close spent waiting is another one to reconcile later.
Twenty years of customizations nobody fully understands
Dexterity mods, VBA on windows, third-party add-ons for project accounting or EFT, SQL jobs and SmartList favorites - GP grew around the business. Nobody has a list, and the person who built half of it retired.
Every advisor sells one destination
The Business Central partner recommends Business Central; the Acumatica reseller recommends Acumatica. Both may be right - but finance wants the trade-offs written down by someone who isn't paid by either.
How the work flows through the system.
Each workflow runs on one shared record, so nobody re-types numbers between steps.
GP assessment and options paper
CFO and controller → Agenbord → IT
- We inventory GP: version, modules in use, companies, user counts by role, table sizes, years of history, add-ons, Dexterity and VBA customizations, SQL jobs, integrations and the reports finance runs.
- We interview AP, AR, payroll, inventory and project teams on what they actually do in GP each week and month.
- We score Business Central, Acumatica, Sage Intacct and a custom option against your requirements, with integration and licensing considerations noted.
- You get a written options paper with our recommendation and a fixed quote for the data migration to your chosen destination.
Data migration with reconciliation
Agenbord → your implementer (if any) → controller
- Master data (chart of accounts with segments, customers, vendors, items, employees) is mapped and cleansed: inactive records, duplicate vendors and unused segments.
- We agree history depth: open transactions and summary GL history by period, with detailed history kept in a read-only GP archive or reporting database.
- Test migrations run into the destination sandbox; trial balance by period, subledger agings, inventory and open POs are reconciled.
- We work alongside the destination's implementation partner where there is one, supplying clean, reconciled data loads.
Custom workflows the package can't handle
Operations → Agenbord → finance
- Requirements no shortlisted package meets well (for example, a pricing engine, a rebate calculation or an industry-specific billing rule) are listed separately.
- Each is assessed: configure in the package, buy an add-on, or build a small custom app that posts to the new ERP via its API.
- Custom pieces are built and tested against the new ERP's sandbox before cut-over.
- Cut-over is planned at a period end, with parallel running for the first close.
What's included in Agenbord Migrate: Dynamics GP.
GP inventory
Modules, companies, users, table sizes, history, add-ons, customizations, SQL jobs and integrations, documented.
Requirements by team
What AP, AR, payroll, inventory and projects actually do in GP, in their words.
Options paper
Business Central, Acumatica, Sage Intacct and custom compared fairly, with a recommendation.
Master data cleanse
Duplicates, inactive records and unused account segments resolved before loading.
History strategy
What moves as detail, what as summary, and a read-only archive of GP for the rest.
Test migrations
Repeatable loads into the destination sandbox until every check passes.
Reconciliation pack
Trial balance by period, AR/AP agings, inventory, fixed assets and open POs compared and signed off.
Custom extensions
Small purpose-built apps for workflows the package can't handle, integrated by API.
GP archive
A read-only reporting copy of GP history so auditors can still drill to the original transactions.
AI that does specific jobs and shows its work.
Every AI feature is tested on your own records before it's switched on, and a person approves anything that moves money or goes to a customer.
Customization discovery
Reads exported Dexterity, VBA and SQL objects and drafts a plain-English description of each customization and the tables it touches. Limits: drafts are verified by our engineers and confirmed by your GP administrator; the inventory used for decisions is the confirmed one.
Who it's for and who it isn't.
A good fit if you are
- GP users with 10–150 users, several companies and years of history in GP
- Organizations with Dexterity customizations, ISV add-ons or SmartList reports that would be costly to recreate
- Finance teams who want an independent comparison before talking to resellers
- GP users whose partner is focused on one destination and who want a second, vendor-neutral opinion
Probably not the right fit if you are
- Organizations that have already chosen Business Central and have a Microsoft partner doing the migration - their tools are built for it
- Very small GP users who would fit QuickBooks Online or Xero with a simple opening-balance migration
- Anyone who needs Microsoft licensing, partner funding or support contracts - we can't provide those
Designed around the rules you work under.

Microsoft's Dynamics GP lifecycle dates
Microsoft stopped selling new GP perpetual licenses on April 1, 2025, and April 1, 2026 was the final day for new customers to license GP subscriptions. Product enhancements, regulatory (tax) updates and technical support end on December 31, 2029. Security updates continue until April 30, 2031. Existing customers can still add users. Microsoft Dynamics 365 blog · Forvis Mazars summary.
Payroll and year-end tax forms
Year-end tax form updates (W-2, 1099) for GP payroll and payables come through the regulatory updates that end with 2029. Organizations running payroll in GP should plan the payroll move for a year boundary no later than that; we time it with your CPA.
Records for audit
The IRS generally expects records supporting a return to be kept for at least three years, longer in some cases. The history strategy and GP archive are set against your retention needs with your auditors. IRS - How long should I keep records?.

How it compares - honestly.
Established products are often the right answer. Here's when each one is the better choice.
| Product | What it is | The better choice when |
|---|---|---|
| Microsoft Dynamics 365 Business Central | Microsoft's cloud ERP for small and mid-sized businesses and its recommended path for GP, with Microsoft-provided migration tooling and a large partner network. | You want to stay with Microsoft, your GP is close to standard, and you value the Microsoft 365 and Power Platform ecosystem. For many GP users this is the sensible default. |
| Acumatica | A cloud ERP licensed by resource consumption rather than per user, with distribution, manufacturing and construction editions. | You have many occasional users, or Acumatica's industry edition fits your operations better than Business Central's add-ons. |
| Sage Intacct | A cloud financial management system strong in multi-entity consolidation, dimensions and nonprofit and services accounting. | Your GP is mostly financials across several entities and you want strong consolidation and reporting rather than operations modules. |
Detailed comparisons: NetSuite alternatives
What it costs, up front.
Assessments and migrations are fixed-price. Price depends on the number of companies and modules, history depth, the number of customizations and integrations, and whether custom extensions are needed. Destination software licensing and any partner implementation are separate.

Phased
Microsoft Dynamics GP users: common questions.
When does Dynamics GP actually end?
Microsoft ended new perpetual license sales on April 1, 2025 and new subscriptions on April 1, 2026. Product enhancements, tax updates and technical support end December 31, 2029, and security updates end April 30, 2031. GP keeps running after those dates, but without updates or support.
Isn't Business Central the obvious answer?
For many GP users it is, and we'll say so when it fits: same vendor, Microsoft migration tooling and a big partner network. Acumatica, Sage Intacct or a custom extension win when licensing model, industry fit or a specific workflow matters more.
Are you a Microsoft partner?
No. We are an independent software company, which is why we can compare options without a commission. If you choose Business Central, a Microsoft partner handles licensing and implementation and we can supply the assessment and reconciled data loads.
How much GP history should we bring?
Usually open transactions plus summary GL balances by period for a few years, with detailed history kept in a read-only GP archive or reporting database. Bringing all detail is possible but costs more and slows every test migration.
What happens to our Dexterity customizations?
They don't move - no destination runs Dexterity. Each one is documented and then configured in the new ERP, replaced by an add-on, rebuilt as a small extension, or retired.
When should we start?
Selection and migration commonly take 9–18 months, and the cleanest cut-over is a fiscal year boundary. Working back from December 31, 2029, most organizations should be choosing a destination in 2027 at the latest.
