Our approach
Built around your organisation
Based in Auckland, we specialise in Microsoft Dynamics 365 Customer Engagement and the Microsoft Power Platform, with decades of experience designing, developing, integrating and supporting business-critical CRM and line-of-business systems.
Dataverse is at the heart of Dynamics 365 Customer Engagement and many Power Platform solutions. Our experience goes beyond configuring tables and building low-code applications. We develop the complete solution — from data architecture and security through to C# plug-ins, custom APIs, integrations, Power Apps, Power Automate, Power Pages and Azure services.
Whether you are extending Dynamics 365, replacing a legacy application, integrating external systems or building a new application on the Power Platform, OA Systems can help design and implement a Dataverse solution that is maintainable, secure and appropriate for your organisation.
The foundation
What is Microsoft Dataverse?
Microsoft Dataverse is Microsoft's cloud data platform for business applications.
It provides structured business data storage together with relationships, security, business logic, APIs, auditing and integration capabilities.
Dataverse underpins applications including Microsoft Dynamics 365 Sales and Customer Service and can also be used to create custom business applications using Power Apps and the wider Microsoft Power Platform.
For organisations already invested in Microsoft 365, Azure or Dynamics 365, Dataverse provides a powerful foundation for applications that need more than a simple database.

C# plug-in and server-side development
Low-code tools are excellent for many business requirements, but they are not the answer to every problem.
OA Systems develops C# plug-ins and other server-side extensions when a solution requires complex business rules, transactional processing, validation, integration or functionality that is better implemented in code.
We design Dataverse plug-ins with careful consideration of execution stages, transaction boundaries, recursion, performance, security and Microsoft's execution constraints.
Where processing is unsuitable for synchronous Dataverse execution, we can design asynchronous or Azure-based architectures rather than attempting to force long-running processes into a Dataverse plug-in.
Dataverse integrations
Business systems rarely operate in isolation. OA Systems integrates Microsoft Dataverse and Dynamics 365 with external applications, APIs, databases and cloud services.
Depending on the requirement, an integration architecture may use:
- Dataverse Web API
- Microsoft Dataverse SDK
- Custom APIs
- Azure Functions
- Azure Service Bus
- Power Automate
- Webhooks
- REST APIs
- Scheduled processing
- Microsoft Entra ID authentication
We select the integration approach according to the business requirement rather than automatically choosing either custom code or low-code automation.
Power Apps and model-driven applications
Dataverse provides the foundation for powerful model-driven Power Apps. OA Systems can build complete line-of-business applications using Dataverse without requiring Dynamics 365 to be the primary application.
This can be particularly effective for replacing spreadsheets, Access databases, legacy applications and disconnected business processes.
Power Pages and external access
When customers, suppliers, contractors or other external users need controlled access to Dataverse information, OA Systems can develop solutions using Microsoft Power Pages.
Power Pages can provide secure web experiences backed by Dataverse while maintaining appropriate separation between internal and external access.
Dataverse security
Security should be designed into a Dataverse implementation rather than added at the end.
OA Systems can design security models using business units, security roles, teams, record ownership, hierarchical security, column-level security, application users and Microsoft Entra ID.
Data migration to Dataverse
Moving data into Dataverse is often more complex than importing records. A successful migration needs to consider data quality, relationships, ownership, option mappings, duplicate detection, historical information, audit requirements and how the target application will use the migrated data.
OA Systems can design and implement migrations from legacy CRM systems, databases, spreadsheets and other business applications into Microsoft Dataverse and Dynamics 365.
Connected solutions
Dynamics 365 and Dataverse
OA Systems has specialised in Microsoft CRM and Dynamics 365 Customer Engagement for decades. That experience is particularly valuable when developing on Dataverse because Dynamics 365 applications use the same underlying platform.
We understand how custom Dataverse development interacts with Dynamics 365 Sales, Customer Service and existing CRM customisations.
Where it fits
When should you use Dataverse?
- Structured relational business data
- Role and record-level security
- Microsoft 365 integration
- Dynamics 365 integration
- Workflow and automation
- Auditability
- External integrations
- Model-driven applications
- Customer or supplier portals
- A managed Microsoft cloud platform
It may not be the right platform for every workload. Part of our consulting approach is determining whether Dataverse is appropriate before recommending it.

Why OA Systems?
OA Systems is a New Zealand Microsoft business applications specialist based in Auckland.
Our work centres on Microsoft Dynamics 365 Customer Engagement, Dataverse and the Power Platform.
Unlike organisations approaching Dataverse solely as a low-code platform, our team combines Dynamics 365 and Power Platform expertise with professional software development and Microsoft Azure integration experience.
That means we can use configuration and low-code capabilities where they make sense while still being able to develop C#, JavaScript, TypeScript, APIs and Azure components when a requirement demands it.
