Application modernization services that clear technical debt, not a risky rewrite.

Application modernization is the work of bringing an existing software application up to date so it is faster, safer and cheaper to change, without throwing away the business logic that already works. It can mean cleaning up the code, moving it onto a supported framework or platform, reshaping its architecture, adding modern APIs, rebuilding a dated interface, or a careful mix of these.

The goal is to clear the technical debt that makes every change slow and risky, rather than change for its own sake. Good modernization keeps what is proven, replaces only what has to go, and moves in small, reversible steps instead of one nervous rewrite. Avaib has delivered software across more than 600 projects since 2004 and applies that same engineering discipline to every application it modernizes.

It depends on the state of the application and the route it needs. A fixed modernization assessment is a small, low-risk first step, while refactoring or re-architecting a whole application is larger. Avaib's model is senior expertise at a cost-effective rate, typically around USD 25 per hour, which is why businesses in Australia, the US, Canada and the Middle East work with us instead of paying big-firm prices.

Tell us about the application you want to modernize, and we will propose a right-sized engagement with a clear scope and a ballpark price, plus a free, no-obligation written estimate after a short scoping conversation.

For most applications, refactoring is the right call. When the core business logic still works but the code has become hard to maintain, cleaning it up fixes the real problem while keeping logic that years of real use have already proven.

A full rewrite only makes sense when the architecture itself is wrong for what the business now needs, and even then a selective rebuild of the worst parts is usually safer than starting over completely. We assess your application and recommend the honest answer, because the ground-up rewrite is often the most expensive and risky path.

It should not cause meaningful downtime. We modernize in small slices and keep the application running the whole time, adding automated tests around each part before we change it so behaviour stays the same.

When a change is ready, we release it carefully and keep a way back until you are happy. There is no big-bang switch-over and no long outage, just steady, checkable progress.

No. We modernize alongside your roadmap rather than in a separate freeze, so the application keeps improving for users while the technical debt comes down in the background.

In fact, once the worst debt is cleared, new features usually ship faster and more safely than before, because the code is finally easy and predictable to change.

We add a safety net first. Before we change a part of the application, we put automated tests around its current behaviour, so we can prove afterwards that it still does exactly what it did.

Our dedicated QA department checks every step, and we keep the old version available until you have signed off. That way modernization is based on proof, not hope.

It ranges from a few weeks for a focused cleanup to several months for a large application with deep debt. The honest timeline comes after the assessment, once we know how the application is built and where the risks sit.

Because we work in slices, you start seeing real progress early rather than waiting for one big delivery at the end, and the timeline stays something you can check as we go.

Yes. Everything we modernize or build for you is yours: the code, the data, the accounts and the documentation. There is no per-seat licence and no lock-in to Avaib to keep it running.

You are free to take it to another team at any time, though most clients stay because they would rather not re-explain a system to someone new.
