Business Central implementation
Functional analysis, parameterization, migration from NAV or other ERPs, training and go-live support.
Dynamics 365
Business Central consulting and custom development for your business.
I'm Alex Pertusa, a consultant and developer specialized in Microsoft Dynamics 365 Business Central. I design, deploy and maintain solutions that adapt to your business — not the other way around.
About
Dynamics 365 Business Central consultant and developer
I help companies implement, tailor and integrate Microsoft Dynamics 365 Business Central. Six years launching ERPs, building AL extensions and connecting them with the rest of the business systems.
I work autonomously but close to every client: functional analysis, development, deployment and follow-up. No middlemen, no surprises.
And as a software engineer, I go beyond Business Central: when a project calls for stepping outside the Microsoft ecosystem —a website, an automation, an integration or a product from scratch— I build it end-to-end too, without handing it off to third parties.

Services
What I can do for your business.
My main focus is the Microsoft stack around Business Central. But if your project needs custom software beyond that ecosystem — a web app, an integration, an internal tool — I build that too.
Custom AL extensions
AL Language extensions that adapt Business Central to your processes without touching the base code.
Connect with your systems
Integrations with e-commerce, EDI, Power Platform and external APIs. End-to-end automated flows.
Maintenance & evolution
Second-level support, evolutions, performance optimization and technical audits on existing installations.
Stack
A consolidated stack.
Main focus on the Microsoft ecosystem around Business Central — combined with a modern web stack (JavaScript, TypeScript, Node.js, React) when the project calls for custom development beyond the ERP.

Process
How I work with every client.
01 / Discovery
Understand the business
Sessions with the team to map processes, identify critical points and understand the real goals.
02 / Analysis
Proposed solution
Functional and technical document with scope, milestones, risks and a closed budget. No fine print.
03 / Implementation
Iterative development
Short sprints with verifiable deliverables. Frequent demos so the client sees real progress.
04 / Go-live & Support
Real follow-up
Training, post go-live support and evolutionary maintenance. I don't disappear after delivery.
