Screens and reports getting slower
Month-end reports take minutes, searches time out and users keep a second tab open while they wait.
Application Maintenance Services Business applications that stay fast, current and secure.
Application management for the systems your business runs on — ERP, portals, customer apps and line-of-business software. We monitor them, tune them, upgrade them and modernise the legacy parts, drawing on 21 years of building and running business applications.

When applications need managing
Six signs your business applications need active management.
Applications age quietly. Data grows, users multiply, frameworks reach end of life and the people who built them move on — until one day the system that runs the business slows to a crawl.
Outages you hear about from customers
Nobody is watching uptime or error logs, so the first alert is an angry call or a lost order.
Running on end-of-life platforms
Old .NET Framework, PHP 5 or 7, AngularJS or Windows Server versions that no longer receive security updates.
A legacy system nobody dares touch
A desktop or VB-era application that works, just about, but blocks mobile access, integrations and growth.
Hosting that doesn't match the load
Over-sized servers wasting money, or under-sized ones that crash at peak hours and during sales.
Admin work eating your team's time
User accounts, masters, data corrections and licence renewals handled ad hoc by whoever is free.
Our application maintenance services
Application management services that keep systems healthy.
Application maintenance services are about running the application well, not just fixing it when it breaks. Pick the services you need or let us manage the application end to end.
Application Monitoring
Uptime, error, response-time and job monitoring with alerts, so problems are seen before users report them.

COTS & Packaged Application Support
Configuration, upgrades and add-ons for commercial off-the-shelf applications alongside your custom systems.
Proactive application monitoring
We see the problem before your users do.
We set up monitoring for uptime, error rates, response times, background jobs, disk space and certificate expiry, with alerts routed to our engineers. Most incidents are caught from an alert or a trend on a dashboard, not from a phone call — and every incident gets a short root-cause note.
- Round-the-clock uptime and error alerting
- Response-time and slow-query tracking
- Scheduled job, queue and integration checks
- Monthly availability and incident report
Application performance tuning
Faster screens, faster reports, lower hosting bills.
Most slow applications have a handful of causes: missing indexes, unbounded queries, heavy pages, chatty APIs or under-sized hosting. We profile the application under realistic load, fix the biggest bottlenecks first and measure every change, so the improvement is visible in numbers, not just felt.
- Profiling of slow pages, APIs and reports
- Query, index and stored-procedure optimisation
- Caching, compression and front-end weight reduction
- Load testing before peak seasons and sales
Upgrades & migrations
Off end-of-life platforms, without a big-bang rewrite.
Frameworks, databases and operating systems all have end-of-support dates. We keep a platform register for each application, plan upgrades well ahead of those dates and run them on a staging copy first, with a rollback plan. The same discipline applies to moving an application to new servers or the cloud.
- Platform register with end-of-support dates
- .NET Framework to modern .NET, PHP 7 to 8, AngularJS to Angular
- Database and server version upgrades
- Cloud or data-centre migration with tested cut-over
Legacy application modernisation
Modernise legacy applications one piece at a time.
Replacing a legacy system in one go is risky and expensive. We usually modernise in stages: wrap the old system with APIs, move the most-used screens to a modern web or mobile front end, migrate the data, and retire old modules only when the new ones are proven. The business keeps running throughout.
- Assessment: retain, re-platform, refactor or rebuild
- API layer around legacy desktop or VB-era systems
- New web and mobile front ends on the same data
- Staged data migration with reconciliation checks
Application administration
Day-to-day application administration, handled.
Somebody has to create users, reset roles, fix wrong data entries, run month-end jobs and keep licences current. We take on that routine application administration under a monthly plan, follow written runbooks, and log every change so you have a full audit trail.
- User, role and permission management
- Master data and data-correction requests
- Month-end, year-end and scheduled job runs
- Runbooks, change log and licence register

FAQ
Application Maintenance Services — frequently asked questions
What are application maintenance services?
Application maintenance services keep business applications running well after launch. They cover proactive monitoring, performance tuning, application administration, database upkeep, integration upkeep, framework and platform upgrades, cloud migration and legacy modernisation. The aim is a system that stays fast, secure and supported, rather than one that is only repaired when it breaks.
How is application maintenance different from software maintenance and support?
Our software maintenance and support service is built around a support contract: bug fixing, QA testing, security patches and a help desk under an SLA. Application maintenance is application management — monitoring, performance, administration, upgrades and modernisation of the systems you run. Many clients use both, and the same Sysfo team can deliver them together.
How much do application maintenance services cost?
It depends on how many applications you have, their size and technology, the hours of cover you need and any upgrade or modernisation work planned. After a free application health review we give you a fixed, itemised quote, usually a monthly retainer for ongoing management and fixed prices for upgrade projects.
Can you maintain an application built by another vendor?
Yes. We start with a transition period of two to four weeks to get access, review the code and hosting, write runbooks and switch on monitoring. If documentation is thin, we create it as we go, so the knowledge belongs to your business rather than one developer.
How do you modernise a legacy application?
We assess each part of the system and decide whether to retain, re-platform, refactor or rebuild it. Usually we add an API layer around the legacy application, build new web or mobile screens on top, migrate the data in stages and retire old modules once the new ones are proven in parallel running.
Do you monitor applications 24×7?
Yes. Uptime, error and job monitoring run round the clock and raise alerts automatically. How quickly an engineer responds outside business hours depends on the cover you choose, and that is written into your plan, along with escalation contacts for critical incidents.
Which technologies does your application maintenance cover?
Our application maintenance services cover .NET and .NET Framework, PHP and Laravel, Java, Node.js, Angular and React front ends, SQL Server, MySQL and PostgreSQL databases, and hosting on Windows Server, Linux, Azure, AWS and Indian data centres. We also support commercial off-the-shelf applications alongside custom software.
Will upgrades disrupt our users?
We plan to avoid that. Upgrades and migrations are rehearsed on a staging copy, scheduled for low-traffic hours, and come with a written rollback plan. For bigger moves we run old and new versions side by side and reconcile the data before switching users over.
Can you reduce our hosting costs?
Often, yes. Performance tuning usually lowers the server power an application needs, and our quarterly capacity review flags over-sized servers, idle resources and unused licences. Any change to hosting is tested first, so savings never come at the cost of stability.
