Application Support Challenges That Need Proactive Attention

Application bugs reported by users — nobody available to fix them quickly?

Security patches overdue — vulnerabilities accumulating?

Performance degrading over time but nobody’s optimising?

No monitoring — problems discovered when users complain?

What We Do

Reliable Support That Keeps Applications Running

SLA-backed response times

Every tier comes with defined response times: 4-hour for Standard, 1-hour for Premium critical issues. Not “we’ll get to it” — a commitment.

We already know your code

We support applications we built and applications others built. We learn your codebase, document it, and maintain institutional knowledge.

Monitoring that prevents outages

Monitor application health, errors, performance, and availability to identify risks before they become larger support issues.

Security kept current

Apply security patches, framework updates, and dependency updates on an agreed maintenance cadence.

Performance maintained

We monitor and optimise performance over time — database maintenance, caching, and query optimisation so applications don’t slow down.

Enhancements without a project

Minor features, UI improvements, and workflow changes delivered within your monthly retainer — no separate project scoping.

Our Services & Capabilities

Application Monitoring

Monitor application health, availability, errors, and performance with environment-appropriate tools and alerts.

Bug Fixes & Incident Support

Resolve production bugs and application issues through defined support processes and response times.

Security & Dependency Updates

Keep applications current with security patches, framework updates, and dependency maintenance.

Performance Optimisation

Identify and address performance issues through database maintenance, caching, and query optimisation.

Application Knowledge & Documentation

Review codebases, document dependencies, and build the technical knowledge needed for ongoing support.

Minor Enhancements

Deliver small features, UI improvements, and workflow changes within the agreed support arrangement

Application Support Plans & Service Tiers

Production-readiness foundation: Onboarding should cover codebase review, dependency and patch assessment, environment access review, monitoring setup, alert routing, backup and recovery checks, release process review, and a documented support runbook before SLAs begin.

How Support Onboarding Works

Free support assessment

We assess your applications: technology, criticality, current issues, and support needs — and recommend the right tier. No cost, no obligation.

Application onboarding (Week 1–2)

We review code, document the architecture, set up monitoring (Application Insights, Azure Monitor), configure alerting, and establish the support channel.

Knowledge transfer

We learn from your team or from the code itself — documenting undocumented logic, dependencies, and operational procedures.

Monitoring goes live

Application monitoring and alerting activated. SLAs in effect. Your team has a dedicated support channel (email, Teams, ticketing).

Monthly cadence

Monthly health report, issue summary, and (Standard/Premium) review meeting with recommendations. Continuous improvement, not just firefighting.

Testing and release management

For bug fixes and enhancements, use a clear release path: issue triage, fix estimate, development or configuration change, peer review, testing in a non-production environment where available, client approval when required, deployment, rollback planning for higher-risk changes, and post-release monitoring.

It starts with a free support assessment. No obligation.

Use Case Matrix: What Does Your Application Need?

Your situation	What you need	Recommended tier
“App works but nobody maintains it”	Monitoring, patches, bug fixes	Basic
“Bugs reported by users, slow response”	Faster SLA + monitoring	Standard
“Need small enhancements each month”	Maintenance + enhancement hours	Standard
“Customer-facing app, can’t go down”	Priority SLA + proactive monitoring	Premium
“Original dev team left, nobody knows the code”	Code audit + ongoing support	Standard or Premium + onboarding
“Multiple apps, no dedicated team”	Portfolio support	Premium
“Performance degrading over time”	Performance monitoring + DB tuning	Performance monitoring + DB tuning
“Security patches overdue”	Security catch-up + ongoing patching	Start with any tier

Freshness Signal: Application Support Priorities for 2026

In 2026, organisations spend tens or hundreds of thousands building custom applications — then neglect them. Security patches go unapplied. Performance degrades. Bugs accumulate. The application that was an asset at launch becomes a liability within a year. Application support isn’t overhead — it’s the protection of your development investment. AI-assisted monitoring now catches anomalies before they become outages, and automated dependency management keeps applications secure between human interventions.

Security patches are non-negotiable — unpatched applications are a common attack path, and a regular patching cadence should be part of every production support plan

Performance degrades without attention — databases grow, queries slow, dependencies age; proactive maintenance prevents the gradual decline

AI-assisted monitoring — can help detect unusual error rates, latency changes, resource spikes, and traffic patterns when the application has sufficient telemetry. For Azure workloads, this may use Application Insights and Azure Monitor capabilities alongside configured alerts and human review.

Support is usually cheaper than replacement — regular maintenance helps extend the useful life of an application and reduces the risk of a forced rebuild after years of neglect

Can't our development team handle support?

Your development team can handle support, but it often competes with roadmap work. A dedicated support retainer separates production maintenance from new feature delivery, helping your developers stay focused while support issues, patches, monitoring, and smaller enhancements are handled through a defined process.

Frequently Asked Questions

What does application support and maintenance include?

Monitoring and alerting, bug fixes and incident response, security patches and dependency updates, performance monitoring and optimisation, database maintenance, minor enhancements (Standard/Premium), and monthly reporting — all with defined SLA response times.

What are the three support tiers?

Basic: monitoring, bug fixes, patches, 8-hour SLA, up to 15 hours. Standard: + performance, enhancements, 4-hour SLA, up to 35 hours. Premium: + dedicated team, proactive monitoring, regular features, 1-hour SLA, up to 80 hours.

Can you support applications that someone else built?

Yes — we support applications we built and applications others built. Onboarding includes a code review, architecture documentation, and knowledge transfer so we understand the system before supporting it.

What SLA response times do you offer?

Basic: 8 business hours (critical). Standard: 4 business hours (critical). Premium: 1 hour (critical). Full SLA table in Section 4 covers all severity levels.

Can we include enhancements in the retainer?

Standard tier includes light enhancements within the monthly hours. Premium includes regular feature development. Basic is maintenance-only (bug fixes and patches). Larger enhancements can be scoped as add-on projects.

What technologies do you support?

ASP.NET Core/.NET Framework on Azure, Blazor, React Native, MERN Stack, .NET MAUI/React Native (mobile), WordPress/WooCommerce, Java, SharePoint/SPFx, Power Platform, APIs, and legacy .NET applications.

How does onboarding work?

Week 1–2: we review code, document architecture, set up monitoring, configure alerting, and establish the support channel. Knowledge transfer from your team or from the code itself. SLAs in effect once monitoring is live.

How is application support pricing calculated?

Pricing depends on the number of applications, technologies, criticality, SLA needs, monitoring scope, enhancement volume, and included support hours. For planning, use $400–$600 per support day as the calculator range. Additional hours, tier changes, and commitment terms should be confirmed during the support assessment.
