WHAT IT MEANS FOR YOU
What Dynamics GP end of support means for your business
COMPLIANCE · FROM 2030
No more tax or regulatory updates
As rules and regulations change, GP won't receive updates to reflect them. You'll need to consider how to keep your processes up to date, including payroll or year-end reporting.
SECURITY · FROM MAY 2031
No more security patches
Microsoft will no longer provide security fixes for GP, so you'll need to think about how best to keep your systems and data protected.
STANDING STILL · ALREADY
No new features, ever
GP will remain as it is, with no new features or enhancements. As your business grows, you may find it harder for your system to keep up with changing needs.
THE COST OF WAITING
Why leaving it until 2029 could cost you more
The deadline might feel a long way off, but moving to a new ERP system takes time, planning and investment. Starting early gives you more time to explore your options, plan your budget and get everything in place without rushing.
Leave it too late, and you could face tighter timescales, fewer options and additional pressure to get everything done.
Why waiting could cost you more
Less time to get it right
Rushing an ERP project can mean cutting corners on data cleansing and testing, increasing the risk of problems after go-live.
Fewer available experts
As the deadline gets closer, ERP partners and consultants are likely to become busier, making it harder to secure the support you need.
Less time to plan your budget
Getting approval for a new ERP system can take time, sometimes a full financial year. Starting early gives you more room to plan.
Limited cut-over windows
Many businesses prefer to switch ERP systems at the end of a financial year. Miss that window and you could be waiting another 12 months.
YOUR OPTIONS
Dynamics GP alternatives: what are your options?
Business Central is Microsoft's recommended route off GP, but it isn't the only one. Here are the three paths most GP users weigh up.
OPTION 1
Stay on GP
Lowest effort today, but no updates after 2029 and no security patches after April 2031. A short-term choice that only delays the decision.
OPTION 2
Move to another ERP
Business Central and other finance systems are all options. Compare each on scope, total cost, deployment choices and the partner who'll deliver it.
OPTION 3
Switch to Odoo
One modular platform for finance, inventory, purchasing, manufacturing, CRM, projects and HR. Run it in the cloud or on your own servers, delivered by a UK Odoo Gold Partner.
GP → ODOO
Dynamics GP vs Odoo: what changes
Leaving GP isn't a like-for-like swap. It's a chance to replace years of add-ons and spreadsheets with one connected system.
| Feature | Microsoft Dynamics GP | Odoo |
|---|---|---|
| Product future | Mainstream support ends 31 Dec 2029; security updates end 30 Apr 2031 | Actively developed, with a new major version released every year |
| Scope | Strong finance and distribution core, often extended with third-party add-ons | Integrated apps for finance, inventory, purchasing, manufacturing, CRM, projects, HR and more on one database |
| Deployment | Typically on-premise or partner-hosted | Odoo Online (SaaS), Odoo.sh or on-premise: your choice |
| User experience | Desktop-first, with a web client | Browser-based and mobile-friendly, with live dashboards |
| Licensing | Closed to new customers since April 2026 | Modular subscription: start with the apps you need and add more as you grow |
WHY ODOO
5 reasons GP users are choosing Odoo
1
One platform, not a patchwork

You don't have to introduce everything at once. Start with the apps your business needs today and add more as your requirements change.
3
Deploy your way
Odoo Online, Odoo.sh or your own servers. Keep the control you had with GP, or move fully to the cloud.
4
Built for UK businesses
UK accounting localisation with VAT and Making Tax Digital VAT returns, plus multi-company and multi-currency for GBP, EUR and USD trading.

FAQS
Dynamics GP end of life: frequently asked questions
Mainstream support for Microsoft Dynamics GP ends on 31 December 2029. After that there are no enhancements, tax or regulatory updates, or standard technical support. Security updates continue until 30 April 2031, when GP is fully out of support.
No. GP will still run, but without tax and regulatory updates from 2030 and without security patches after 30 April 2031. That makes it increasingly hard to stay compliant and secure.
No. Business Central is Microsoft's recommended route, but you can move to any ERP. Many GP users choose Odoo because it brings finance, inventory, purchasing, manufacturing, CRM and HR into one modular platform that can run in the cloud or on your own servers.
It depends on your modules, add-ons, integrations and how much history you bring across. We confirm a timeline after a discovery phase. Starting early lets you plan go-live around a fiscal year end and run GP and Odoo in parallel.
Typically your chart of accounts, customers, vendors, items, opening balances and open transactions, plus as much historical data as you need for reporting and audit.
Yes. Odoo's UK localisation includes a UK chart of accounts, VAT setup and Making Tax Digital VAT returns submitted to HMRC, which we configure for your business.
Yes. Odoo can run as Odoo Online (SaaS), on Odoo.sh, or on your own servers or private cloud.
Now. Budget approval, data preparation and testing all take time, and partner capacity tightens as the 2029 deadline approaches. Planning in 2027 gives most businesses a calm go-live well before support ends.
