Software maintenance services that keep your application secure, current and healthy.

Software maintenance is the ongoing, planned work of keeping an application healthy, secure and useful after it has been built and launched. It covers applying security patches, updating the third-party libraries and frameworks the software depends on, fixing the bugs that surface as it is used, tuning performance as data and traffic grow, making small improvements, and keeping everything compatible as browsers, operating systems and connected services change around it. In short, it is the steady upkeep that stops working software from quietly decaying between big projects.

It is often described in four types: corrective (fixing faults), adaptive (keeping up with a changing environment), perfective (improving what already works) and preventive (heading off future problems, such as security patching). Avaib has delivered and maintained software across more than 600 projects since 2004, and a maintenance plan puts a senior team in charge of that upkeep so your software stays secure, fast and current for years rather than falling behind after launch.

The four recognised types are corrective, adaptive, perfective and preventive maintenance. Corrective maintenance fixes faults and errors that surface as the software is used — the bugs, crashes and wrong results. Adaptive maintenance keeps the software working as its environment changes, such as a new operating system, browser, device or a third-party service it connects to. Perfective maintenance improves a working system — refining features, tuning performance and tidying code so it keeps getting more useful. Preventive maintenance heads off future problems before they happen, through security patching, dependency updates and refactoring fragile code.

A good maintenance plan covers all four. Most businesses only think about the corrective kind — fixing things when they break — but it is the preventive and adaptive work that quietly saves the most money, by stopping small issues from ever becoming emergencies.

Because software that is not maintained does not stay still — it decays. Security holes go unpatched, dependencies fall out of support, small bugs pile up, and performance drifts. The cost of that neglect is well documented: the majority of successful cyberattacks exploit a vulnerability a patch already existed for, and fixing a problem after it hits can cost many times more than preventing it. Neglected systems tend to present their bill all at once — as a breach, an outage, or a forced rebuild — at the worst possible moment.

Regular maintenance keeps that from happening. It keeps your software secure, quick and reliable, protects the investment you made building it, and turns unpredictable emergencies into a steady, manageable schedule.

It depends on the size and complexity of the software, how current it is to begin with, and how much upkeep it needs each month. Maintenance is usually priced either as a predictable monthly plan for an agreed scope, or as blocks of senior hours you draw on as needed. 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 maintenance prices.

After a short conversation about your software and what it needs, we will send you a free, no-obligation written estimate with a clear scope and a ballpark figure, so you know exactly what is included and what it costs.

That is the main worry people have, and it is why we do maintenance the careful way. Every change is tested by a dedicated QA department before it goes live, and we update in small, safe steps rather than large risky jumps, so a fix in one place cannot quietly break another.

Done properly, maintenance lowers your risk of breakage rather than adding to it. The far bigger risk is leaving software un-updated until a forced, all-at-once upgrade becomes unavoidable and genuinely dangerous.

Yes — it is one of the most common things we do. Many businesses come to us because the developer or agency that built their software has moved on, often leaving little or no documentation behind.

We start by auditing and learning how the system actually works, document it as we go, bring security and dependencies up to date, and then keep it healthy on an agreed schedule. You do not need the original developer, and you do not need to start again.

They work together but are not the same. Maintenance is the planned, proactive upkeep that keeps the code healthy — security patches, dependency updates, bug fixes, performance tuning and small improvements — so that problems are prevented. Support is the reactive side: a team ready to respond when something breaks or a user needs help, within agreed response times.

Put simply, maintenance keeps the software current so there is less to go wrong, and support responds quickly when something does. Many businesses want both, which is why they are often combined, or wrapped together with monitoring and changes into a managed application plan.

Security patches should be applied as soon as they matter — a critical vulnerability cannot wait for a quarterly cycle. Dependency updates, bug fixes and small improvements are best handled on a regular, agreed cadence, often monthly, so nothing falls far behind.

The exact rhythm depends on how critical and how heavily used the software is. We agree a schedule with you up front that keeps security current and the system healthy, without disrupting your users, and we adjust it as your needs change.
