Microsoft Dynamics AX or GP: Understanding the fundamental differences

According to recent Microsoft customer figures, Dynamics GP is leading the growth in the Microsoft Dynamics ERP space, adding new customers at the rate of 9.3%. Meanwhile, in the last year, AX has added new customers at the rate of 5.6%.

As somebody who has been working with Microsoft partners reselling both Dynamics GP, AX and NAV, these numbers are not very surprising. Each product has its target markets and areas of strengths. Microsoft has been pushing AX very strongly for large scale deployments, and GP for small to mid-sized organizations. The question about comparing GP against AX comes up so often that I have a few slide in my typical presentation that I run though as soon as somebody brings up the question.

Construction specific erp

Hello jivtesh,

Thanks for this wonderful blog site. I am looking for one of the dynamics product that will be suitable for a construction company . Is there such a product that is available or some add on modules that will support the construction specific requirement. There are approximately 100 users.


RE: Construction specific erp

Hi Samit -

Their is a great solution that works with the Microsoft Dynamics AX platform for the Architecture, Engineering, and Construction industries called Project Pro. The solution is built right into the Dynamics AX solution. Here is a link for additional information

IPM Construction Project Management

Hi Samit
Responses so far have assumed you're looking for a construction erp solution. However those solutions don't typically address the operations side of your projects, i.e. project management, very well. You don't state exactly what your needs are so if they include tools and capabilities for your teams in the field to manage documents (RFI's, meeting minutes, issues, etc.), change management, contract control and planning & forecasting you may want to explore an option like IPM. It is built on Microsoft's xRM platform so it is very scalable and allows it to run inside of Outlook (where project teams spend the vast majority of their time) and automatically file email for you. It also is an extremely flexible system allowing you to configure it around your company's way of doing business. Integration with most of the erp packages mentioned by others allows important cost information from accounting to be accessible by project managers in IPM for reporting and creating forecasts. Mobility options allow use of mobile devices to input data, create documents and send email.

Theses are just a few of the capabilities. Please feel free to contact me if you'd like more information.

demand forecasting on GP


We are current MSD GP users. we are in an industry with highly seasonal demand patterns. Out of the box, MSD GP does not have much capability to automatically calculate the ROP based on sales history and demand patterns.

Is there an add-on package which would allow a dynamic and automated calculation of re-order points?


Dynamics GP with Wennsoft

Hi Samit,

Dynamics GP with Wennsoft is a great fit for Construction. You can read more about Wennsoft and Dynamics GP

Let me know if you have any specific questions.

Two GP Options

Your decision will depend on your budget. A GP solution will likely be far less than an AX solution.

IMHO there are two products you should seriously look at from the GP ISV perspective. Olympic Systems Project Cost is the most widely used and least complicated produce. WennSoft is a great option if the complexities of your solution include options like assigning heavy equipment to a job. WennSoft has a Job Cost product and a Service Maintenance product and a Maintenance Contract module - each of which can be purchased separately based on your needs.

I would suggest that you avoid the built in Microsoft Dynamics GP Project Accounting module. There are a number of reasons for my caution here and I'd be happy to discuss one-on-one once you make the major GP vs. AX decision.
Best to you

Fantastic article

Fantastic article Jivtesh...I agree 100%... I always say that GP is a fully functional ERP system with tools to extend it e.g. Dexterity and .NET whilst AX is a Development platform with an ERP system
