Microsoft Dynamics 365 Business Central AL Extensions & Apps

Extend your cloud ERP with modern, upgrade-safe AL extension packages (.app). Winzi Technologies and Winzi Dynamics build custom Per-Tenant Extensions (PTE) and ISV AppSource products for organizations across the USA, Dubai & Abu Dhabi (UAE), the UK, Australia, and India.

Cloud-Compliant AL Extensions That Stand the Test of Time

Legacy Microsoft Dynamics NAV implementations relied on modifying core base code, which created massive friction during version upgrades. In Microsoft Dynamics 365 Business Central SaaS, all bespoke functionality must be delivered through standalone, decoupled AL extensions.

At Winzi Technologies, our senior AL architects specialize in building event-driven extensions using Visual Studio Code. We write clean table extensions, page extensions, and codeunits that subscribe to standard events without breaking core application code. Whether you need custom business logic built under our Business Central AL Development Services, bespoke UI Customizations, or integrations with Dynamics 365 CRM and Power Platform, our extension packages ensure smooth bi-annual Microsoft release wave updates.

1. Per-Tenant Extensions (PTE) (.app)

Bespoke AL extensions engineered specifically for your enterprise environment. We build custom fields, pages, reports, and posting logic, compiled into clean `.app` packages for direct deployment into your Business Central production tenant.

2. AppSource ISV Product Development

Transform your vertical IP into commercial AppSource products. We handle the full development lifecycle—from AL coding and automated testing to Microsoft technical validation and AppSource marketplace publishing.

3. Event-Driven Architecture & Subscribers

Say goodbye to core code modifications. We utilize Microsoft's native event subscriber pattern, hooking into standard database triggers to execute custom validation rules and workflow automations safely.

4. Legacy C/AL to Modern AL Refactoring

Upgrading from Dynamics NAV? We refactor legacy C/SIDE C/AL code modifications into clean, modular AL extensions, preserving your proprietary business logic during cloud migration under our Business Central Migration Services.

5. Custom API & OData Web Service Pages

Build high-performance, custom API pages in AL. We expose structured JSON/OData endpoints that allow external applications, mobile apps, and e-commerce platforms to query and post data directly to Business Central via BC Integrations.

6. Azure DevOps ALM & CI/CD Pipelines

Automate build, test, and release cycles for your AL extensions. We set up Azure DevOps CI/CD pipelines with automated compiler checks to test extension compatibility against future Business Central preview builds under our Maintenance Services.
