Maintaining existing software

Ongoing maintenance

Many businesses run on software that has been around for years. Replacing it is expensive and takes time, and the people who built it are often no longer around. We take over existing software, get to know the system, document how it works, and keep maintaining and building on it.

How is your software doing? The free quickscan takes 2 minutes and gives you an overview of your current system and where it can improve.

What we do

Maintaining and updating existing software

We've maintained and extended existing code for years, including systems that are past their prime. First we find out how your system works and where the risks are. Then we decide together what to fix, update or leave as it is.

PHP

Updating older PHP versions

We know our way around older PHP versions, including PHP 5.6. We keep your system running and, where needed, propose how to move it to a PHP version that still gets security updates.

JavaScript

Updating React, Angular

We work in older JavaScript codebases, including applications built with React or Angular. We update them, clean up where needed, and extend them when your business needs something new.

Ruby on Rails

Updating Ruby and Ruby on Rails

We take over older Rails applications, update Ruby and Rails, and keep building on them. Along the way, we make them faster and easier to maintain.

Tell us about your system

Did someone else build your system, or has the work on it stalled? In a first conversation, we look at what's there, what it needs and whether we're the right team for it.

Schedule introduction

How we take over your software

We look at the current state of the code. Are there urgent problems? Which technology was used, and how is the code holding up? What's the next step? In this step, we both find out whether we're a good fit.

Next, we audit the existing code. We check the technology and versions, look for security issues and assess the state of the code. That shows us where we can help most.

The introduction and audit usually bring the weak spots to light. Together we plan how to tackle them, in a roadmap with clear steps. We document how the system works and keep that documentation up to date, so everyone knows where things stand.

We walk through all the plans one more time, gather the last information we need and make sure everything is ready to start the work.

Once the details are settled, the work starts. Both teams have the information they need to run the project. We schedule regular check-ins to keep you informed, and adjust course where needed.

Our case studies

Training software, rebuilt and automated

How BITEG automated invoices, certificates and seminar dates, and saves 20+ hours a week

BITEG runs 800 training seminars a year. Invoices, certificates and website updates were done by hand, on old custom software that nobody supported anymore. We built a new system that does this work automatically and saves more than 20 hours a week. Read more >

Automation Software

Hello Host

Our own portal for clients, subscriptions, invoices and hosting

Hello Host is the management software we built for our own team. Development started in 2020. Today we use it every day, together with our clients, for client accounts, subscriptions, invoices, hosting and tickets. Read more >

Software Automation

Patient platform for prostate diagnostics

From ordering a test kit to reading the lab result

Since 2019 we have worked with ALTA Klinik on improvements and automation. One of the main projects is a patient platform for prostate cancer test kits: ordering, payment, shipping and lab results in one system. Read more >

Frequently asked questions

Software becomes a problem when security updates stop, your hosting no longer supports the PHP or database version, new integrations no longer work, or performance problems can't be solved. Age alone says little. What matters is the technical limits combined with what you'll need next.

PHP 8.2, 8.3, 8.4 and 8.5 currently still receive updates. PHP 8.5 has been the newest version since November 2025. PHP 8.4 gets active support until the end of 2026 and security updates until December 31, 2028. PHP 8.3 gets security updates until December 31, 2027, and PHP 8.2 only until December 31, 2026. PHP 8.1 and all earlier versions, including PHP 7.4, no longer receive security updates and are a security risk.

The longer you wait, the wider the gap with what is standard today. Security holes become a bigger risk, maintenance gets more expensive, and new features or integrations get harder. It also becomes harder to find developers who want to work with the old technology. A rule of thumb: if annual maintenance costs more than half of what a rebuild would cost, renewing is usually the better choice.
