Extensions are how Business Central is meant to be extended today — Microsoft retired direct code modification years ago in favor of the AL extension model. Winzi Dynamics builds per-tenant and AppSource extensions that add exactly the functionality you need while staying fully compatible with every future Business Central update.
An extension is a self-contained package of code — new tables, pages, reports, and business logic — that sits alongside Business Central's base application instead of modifying it. That separation is what makes extensions upgrade-safe: when Microsoft ships a new version, your extension keeps working (or flags a clear compatibility issue) instead of silently breaking. We design, build, test, and maintain extensions end to end, whether you need a one-off internal extension or a polished app for Microsoft AppSource.
We develop extensions for businesses and ISVs across the USA, UK, Dubai and Abu Dhabi (UAE), and Australia, including extensions built to meet region-specific regulatory or localization requirements.
Custom extensions built and deployed specifically for your Business Central environment — internal tools, industry-specific functionality, or business logic that only your company needs, without going through app store certification.
If you're building a product to sell, not just a feature for internal use, we develop extensions to Microsoft's AppSource certification standards — multi-tenant ready, properly licensed, and built for a broader customer base.
Every extension starts with a design pass: which events to subscribe to, how to extend tables and pages without conflicting with other extensions, and how to structure the app for maintainability as requirements grow.
Still running old-style C/AL customizations from an on-premise NAV or early Business Central setup? We convert them into modern AL extensions, so your customizations survive on-premise-to-cloud moves and future upgrades.
Automated test codeunits, upgrade-path testing, and validation against Microsoft's AppSource technical requirements, so extensions ship with confidence and pass certification on the first submission.
We handle packaging, versioning, and the AppSource submission and validation process end to end, including responding to Microsoft's technical review feedback, so your app makes it to market without delays.
Ongoing maintenance to keep your extensions compatible as Microsoft ships quarterly Business Central updates — version bumps, dependency checks, and fixes before an update ever reaches your production environment.
If what you need is standard configuration, custom reports, or workflow changes rather than new packaged functionality, see our Customization services for the full range of ways we tailor Business Central to your business.
Businesses that need packaged, reusable functionality rather than one-off configuration — and ISVs or product teams building an app to publish and sell on Microsoft AppSource — across distribution, manufacturing, professional services, retail, and software sectors.
We build and support extensions for Business Central customers and ISVs across multiple time zones and regions, with the localization know-how to handle tax, currency, and reporting differences between the USA, UK, UAE, and Australian markets in a single codebase where possible.
