Microsoft development company
Picture your Microsoft software running as one connected system, with the vendor juggling and the chasing gone. Avaib has more than twenty years on the Microsoft stack, with deep in-house strength in .NET and C#, Azure and SQL Server, plus vetted specialist partners for SharePoint and Dynamics 365. Senior specialists, one point of contact, and code and accounts you own outright.
Delivered for teams in Australia, the United States, Canada and the Middle East.
Built on Microsoft, joined up properly
The Microsoft stack (.NET and C# for custom software, Azure for the cloud, SQL Server for data, and SharePoint, Dynamics 365 and the Power Platform for collaboration, CRM and low-code) powers a huge share of the business systems companies rely on, and it is one of the foundations we work in across the wider technology stack.
The trouble is how it usually gets built. One firm does the .NET app, another the SharePoint intranet, a third the Dynamics CRM, and the integrations between them, the part that actually delivers the value, become nobody's job. You end up the accidental systems integrator, spending your week chasing hand-offs you never signed up for.
Avaib fits the other way round. We build the core in-house (.NET, C#, Azure and SQL Server), coordinate vetted specialist partners for SharePoint and Dynamics, and own the joins between all of it. The result: your Microsoft estate runs as one system, you have a single person to call, and the code and accounts stay yours. Prefer to build up your own team instead? You can also hire Microsoft developers from us across .NET, C#, Azure and SQL Server.
Building on .NET, moving to Azure, or bringing SharePoint and Dynamics into the picture? One team can own all of it.

From custom .NET software and Azure cloud to SharePoint, Dynamics and the Power Platform, here is the range we cover. We are clear about which pieces are built in-house and which we deliver through specialist partners, so you always know who is doing what.
Secure, high-load business systems on the .NET platform, plus safe migration of ageing .NET Framework apps to modern .NET in slices. Our deepest Microsoft capability, built in-house since 2004.
Explore .NET development →Senior C# across every surface the language reaches: web, desktop, cloud, cross-platform with .NET MAUI, and AI features. One accountable team covers the whole estate, so you stop stitching together a separate vendor for each surface.
Explore C# development →Fast, secure ASP.NET Core web apps, APIs and real-time systems built for production, with old Classic ASP and Web Forms sites modernised to current ASP.NET Core in safe slices.
Explore ASP.NET development →Cloud-native applications on Azure App Service, Functions, containers and managed SQL, or moving an existing app onto Azure, so your software scales, stays secure and avoids runaway bills. Accounts and infrastructure you own.
Explore Azure development →Database design, performance tuning, reporting and integration on SQL Server and Azure SQL, so the data layer under your Microsoft software is fast, reliable and properly modelled for how your business actually works.
Document management, intranets and collaboration on SharePoint, delivered through vetted specialist resources we bring in and coordinate. You get the SharePoint capability with a single accountable point of contact at Avaib.
Explore SharePoint consulting →CRM and business-application work on Microsoft Dynamics 365, delivered through trusted specialist resources under Avaib coordination, so you can add Dynamics to a Microsoft project without sourcing a separate vendor yourself.
Explore Dynamics 365 consulting →Power Apps, Power Automate and Power BI to put low-code apps, workflow automation and reporting on top of your Microsoft data, wired cleanly into the .NET, Azure and SQL systems we build.

Get a free quoteThe multi-vendor Microsoft trap
This is the most common situation we are called in to fix. It is nobody's fault; it is just what happens when each Microsoft piece is sourced separately, and everything about how we work is built to avoid it.
One firm does the .NET app, another the SharePoint intranet, a third the Dynamics CRM. Each knows its own corner and none owns how they fit together, so the whole picture is nobody's job.
The value lives in the software talking to each other: .NET to SQL, Dynamics to your app, SharePoint to your data. That is exactly where separate vendors point fingers instead of fixing the join.
With no single accountable team, coordinating the vendors, chasing the hand-offs and owning the risk quietly lands on you, which is not the job you set out to do.
The value of a Microsoft estate is in the pieces working together. Spread across vendors, the seams between them become the one thing nobody owns, and that is exactly where the cost, the delay and the risk quietly pile up on you.
How we cover the whole stack
We would rather be straight than oversell. Here is exactly how Avaib delivers across the Microsoft stack, so you know what you are getting on each piece.
Our core Microsoft capability, staffed by senior engineers who have worked the stack since 2004, backed by our own QA department and a 30-day warranty.
For SharePoint and Dynamics we bring in vetted specialist resources and coordinate them for you, so you get the capability with a single accountable point of contact at Avaib rather than sourcing another vendor yourself.
The concerns, answered
These are the real concerns we hear before a Microsoft build starts. Here is exactly how Avaib takes each one off the table.
Why Avaib
Plenty of teams can write C#. Fewer pair two decades of in-house Microsoft depth with an honest, coordinated way of covering the whole stack, at a price that does not punish you for it.
Building C#, ASP.NET, Azure and SQL Server software since 2004 across more than 600 projects, from enterprise web systems and APIs to ERP, CRM and cloud platforms.
Instead of juggling separate vendors for .NET, Azure, SharePoint and Dynamics, you get a single point of contact at Avaib that owns how the pieces fit together.
.NET, C#, Azure and SQL are built by senior engineers here; SharePoint and Dynamics are delivered through vetted specialist partners we coordinate. We tell you which is which.
Picture the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, delivered by senior Microsoft engineers from around USD 25 per hour. One Canadian media and broadcasting client reduced its development investment by roughly 75% versus local vendor quotes, and received the same high-quality solution backed by a 30-day warranty.
Our senior engineers use advanced AI coding tools to move through the build faster, steering and reviewing every step, so you see working software sooner while the quality bar stays exactly where it should.
The code, the data, the documentation and the Azure accounts stay yours, on standard, well-supported Microsoft technology you can hire for, so there is no lock-in to us.

Get a free quoteHow we work
Understand your systems first, agree a clear scope across the stack, build and integrate in provable slices, then launch and support, so you always see progress and never face a single risky switch.
We start with what your Microsoft software has to do, who uses it and what it connects to, including any existing .NET app, SQL database, Azure tenancy or Microsoft tools, so the plan is grounded in your real situation.
You get a plain-language scope with defined outcomes, so you know exactly what will be built across the stack, which pieces are in-house and which use specialist partners, in what order, and what it will cost before any development begins.
Senior specialists build in slices, each tested by our QA department, and we own the integrations between your .NET app, SQL data, Azure services and Microsoft business tools so the stack works as one system.
We help you roll it out on Azure or the infrastructure you choose, support it under a 30-day warranty and beyond, and extend it as your needs change, on a foundation built to last.
Pricing
The same capability Australian, US, Canadian and Middle-East firms charge a fortune for, delivered by senior Microsoft engineers from around USD 25 per hour, at a fraction of the price. We scope the work clearly up front so you get a fixed, plain-language quote, and every engagement leaves you owning your code, data, documentation and Azure accounts outright.
For a clearly scoped Microsoft application or module, we agree the scope and the price up front, then deliver and test it against your real requirements.

Common questions
Microsoft development is the building of software on Microsoft's technologies — most commonly the .NET platform and C# language for custom applications and APIs, Azure for cloud hosting and services, SQL Server for data, and business platforms like SharePoint, Dynamics 365 and the Power Platform. Together these cover everything from bespoke enterprise systems to collaboration, CRM and low-code apps.
A Microsoft development company designs, builds, integrates and maintains this software for you. Avaib has worked on the Microsoft stack since 2004, across more than 600 projects, with deep in-house strength in .NET, C#, Azure and SQL Server, and specialist-partner delivery for SharePoint and Dynamics.
We do both, but we are honest about how. .NET, C#, Azure and SQL Server are our deep in-house strengths, built by senior engineers here since 2004. SharePoint and Dynamics 365 we deliver through vetted specialist resources we bring in and coordinate for you.
The advantage for you is a single accountable point of contact at Avaib across the whole Microsoft stack, so you can add SharePoint collaboration or a Dynamics CRM to a project without sourcing and managing a separate vendor yourself.
Yes, that is exactly the role we take. Rather than you juggling one vendor for the .NET app, another for SharePoint and a third for Dynamics, Avaib is the single accountable team that owns how the pieces fit together, including the integrations between your app, your SQL data, Azure services and Microsoft business tools.
We build the in-house pieces ourselves and coordinate the specialist SharePoint and Dynamics work, so the coordination, hand-offs and integration risk are our job, not yours.
No. You own the code, the data, the documentation and the Azure accounts throughout. We favour standard, portable .NET and keep Microsoft-specific pieces cleanly separated, so your software can move to another team, and where sensible another cloud, if you choose.
Our work is backed by a 30-day warranty and optional ongoing support, but the relationship continues because it keeps delivering value, not because you cannot leave.
It depends on the scope, since a focused .NET tool is very different from a system that runs your whole operation or a mixed estate spanning .NET, Azure, SharePoint and Dynamics. That is why we scope the work clearly up front and give you a fixed, plain-language quote before any development starts.
Our senior Microsoft engineers work at a cost-effective rate of around USD 25 per hour, the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, and AI-accelerated delivery helps get you there faster. After a short conversation we send you a free, no-obligation written estimate with a clear scope.
The Microsoft stack is one of the most trusted foundations for secure, high-load business software, which is why it is common in finance, healthcare, government and other regulated sectors. .NET, Azure and SQL Server have mature security tooling, strong performance and long-term support from Microsoft.
We have built exactly this kind of system since 2004, designing to the security and compliance bar your environment requires, working with your existing authentication, Azure tenancy and infrastructure, and testing every slice through our dedicated QA department.
