Development Capabilities
What our D365FO developers build
X++ extensions & customisations
Forms, tables, methods, business logic
Data entities & integrations
OData, custom services, batch jobs
ALM & deployment automation
Azure DevOps, LCS, build pipelines
All development follows Microsoft's extension-first model. No over-layering. Upgrade-safe code that survives every D365FO platform update.
Most D365FO customisations break with every platform update because they over-layer Microsoft code. Impacgo builds upgrade-safe extensions that survive every Wave release.
What We Build
Complete D365FO Development Services
X++ extensions, custom forms, integrations, data entities, reports, batch jobs, security — every type of D365FO customisation you need.
X++ Extensions & Customisation
Custom forms, tables, methods, business logic, validation rules, workflows, and reports. All built using Microsoft's extension-first model — no over-layering, no upgrade risk.
Data Entities & OData
Custom data entities for integration, import/export, and external system communication. OData endpoint development for real-time data exchange with web and mobile apps.
Custom Reports & Analytics
SSRS reports, paginated Excel exports, electronic reporting (ER), and custom queries. Embedded Power BI reports inside D365FO forms for live operational dashboards.
Integration Development
REST/SOAP services, Azure Service Bus connections, custom integration patterns, file-based imports, and middleware orchestration with Logic Apps or Azure Functions.
Security & Compliance Development
Custom security roles, duties, privileges, and segregation-of-duties rules. Row-level security policies for sensitive data. Audit trails and compliance frameworks for Indian regulations.
Batch Jobs & Background Processing
Custom batch jobs for nightly reconciliation, data archival, integration polling, scheduled reports, and bulk processing. Performance-tuned to run within batch windows.
Why Impacgo
Why Choose Impacgo for D365FO Development?
D365FO development specialists with proper engineering discipline — not freelance over-layering.
Microsoft D365FO Specialisation
We do D365FO development only — not generic .NET or Java. Deep platform knowledge, current with the latest Microsoft updates and Wave releases.
Extension-First, Upgrade-Safe Code
Every line of code we write follows Microsoft's extension model. Your customisations survive every D365FO platform update without breaking.
Azure DevOps & ALM Discipline
Git source control, build pipelines, automated tests, code reviews, release management — proper engineering discipline, not cowboy development.
Legacy AX Experience
Our team has worked on AX 2009, AX 2012, and D365FO. We understand legacy customisations and can re-architect them for the modern extension model during migration.
Dedicated Developer Model
Most clients prefer our dedicated D365FO developer engagement — your own X++ developer or pod working as an extension of your team. No scope negotiation overhead.
Cloud Deployment Expertise
Full LCS (Lifecycle Services) experience. Tier-2/Tier-3 environment management. Sandbox-to-production deployment via Azure DevOps. No more zip-and-pray deployments.
Our Process
D365FO Development Engagement Process
Requirements to production — agile sprints, code reviews, automated builds, hypercare.
Requirements & Technical Scoping
Detailed requirements workshop with your business and IT stakeholders. We translate business needs into D365FO technical specifications — extensions, data model changes, integrations, security implications. Deliverable: functional design and technical design documents.
Solution Architecture & ALM Setup
Solution architecture for the customisation — extension models, integration patterns, performance considerations, security design. Azure DevOps repository setup, build pipelines, branching strategy. Deliverable: architecture document and ALM infrastructure ready.
Development in Sprints
2-week development sprints with weekly demos. Developers work in feature branches with mandatory code reviews. Unit tests for critical business logic. Integration tests for data flows. Deliverable: working customisation incrementally delivered to UAT environment.
Testing & Quality Assurance
Functional testing, integration testing, performance testing, and user acceptance testing. Regression testing against existing D365FO functionality. Automated test cases added to CI pipeline for ongoing protection.
Deployment & Cutover
Promotion through Tier-2 → Tier-3 → Production via Azure DevOps and LCS. Deployment runbook with rollback plan. Cutover during agreed maintenance window. Smoke testing immediately post-deployment.
Hypercare & Ongoing AMS
4-8 week hypercare with daily monitoring and immediate issue response. Knowledge transfer to your team. Transition to ongoing managed services for continuous enhancements, platform update support, and performance tuning.
FAQ
D365FO Development — Frequently Asked Questions
What is X++ and why do D365FO customisations need it?
X++ is the proprietary programming language used by Dynamics 365 Finance and Operations (and its predecessor, Dynamics AX). All D365FO customisations — custom forms, business logic, batch jobs, integrations, security rules — are written in X++. While Microsoft offers many no-code/low-code options through Power Platform, deep ERP customisations still require X++ expertise. Impacgo's developers are X++ specialists with years of D365FO and legacy AX experience.
What's the difference between extensions and over-layering in D365FO?
Over-layering was the customisation model in legacy Dynamics AX where developers modified Microsoft's source code directly. This created upgrade nightmares — every Microsoft update could break custom code. In D365FO, Microsoft enforces an extension-first model: you extend or augment Microsoft's code via hooks and event handlers without modifying it. The result is upgrade-safe customisation. Impacgo builds all D365FO development using extensions, never over-layering — your code survives every D365FO platform update.
Do you support Azure DevOps and CI/CD for D365FO?
Yes. We set up full ALM (Application Lifecycle Management) for D365FO using Azure DevOps. This includes source control with Git, automated build pipelines, release pipelines for deployment to Tier-2/Tier-3 environments, automated testing, and LCS (Lifecycle Services) integration. Multi-developer teams can work in parallel safely. Code reviews and pull requests are mandatory. No more emailing XPP files between developers.
Can you integrate D365FO with our other business systems?
Yes. We build D365FO integrations using OData entities, custom services (SOAP/REST), data import/export framework (DIXF), Azure Service Bus, Azure Logic Apps, and direct database APIs where appropriate. Common integrations include CRM systems, e-commerce platforms (Shopify, Magento), banking and payment gateways, logistics partners, MES, IoT, and custom legacy applications. We follow integration patterns that are reliable, monitorable, and recoverable.
How do you charge for D365FO development work?
We offer two engagement models: (1) Fixed-price for well-defined scope projects (e.g., a specific custom report, a defined integration). (2) Time and materials with a dedicated D365FO developer or developer pod for ongoing development needs. Most clients with continuous customisation needs prefer the dedicated developer model — predictable monthly cost, full team integration, no scope negotiation overhead.
