Maintenance that understands your stack

Every application type has different maintenance needs. We know the difference — and we cover all four.
mobile app solutions icon-1

Mobile App

iOS and Android apps need ongoing care as operating systems, devices and app store policies evolve. We keep your app current, compliant and crash-free.
Swift / SwiftUI · Kotlin · Flutter · React Native · iOS updates · Play Store compliance
icons8-recruiting-1

Web App

Web applications need framework updates, dependency management and security patching to stay fast and secure. We monitor and maintain across the full stack. Running WordPress? See our dedicated WordPress maintenance plans.
Node.js · React · PHP / Laravel · Python / Django · PostgreSQL · Vue / Angular
icons-module-1

Custom Software

Bespoke enterprise software needs the same care as consumer apps — often more. Server patches, database maintenance, security hardening and performance monitoring. Need the underlying cloud set up or managed too? That's our managed cloud DevOps service.
Server patches · DB optimisation · Security hardening · API maintenance · Performance

AI Project

AI features degrade silently — models drift, APIs deprecate, prompts stop performing. We monitor, update and maintain your AI integrations so they keep working as the platforms evolve.
LLM API versioning · Prompt engineering · RAG systems · Model monitoring · Drift detection · Cost optimisation

Sound familiar?

The three most common reasons Australian businesses call us about enterprise maintenance.
apple-logo

“Apple released iOS 18 and our app crashes on the latest iPhones. We’ve had 200 one-star reviews in a week.”

No developer monitoring compatibility. No one watching for OS update impacts before they hit production. 72 hours of negative reviews before anyone knew.
warning

“Our lead developer left six months ago. Our Node.js app is four major versions behind.”

Technical debt accumulates fast when nobody’s looking. Four major Node versions behind means dozens of known vulnerabilities and a growing attack surface.
icon-recruitment4

“OpenAI deprecated the model we built on. Our AI feature stopped working overnight.”

AI platforms evolve constantly. Without active monitoring of API versions and model deprecations, your AI feature fails silently. This is becoming the most common call we receive.

What happens after you sign up

Whether you’ve built with us before or you’re a brand new client, here’s how enterprise app maintenance works from day one.
Stage 01

Onboarding audit

We review your entire application — codebase, architecture, dependencies, security posture and performance baseline.

 

  • Full codebase & architecture review
  • Security vulnerability scan
  • Written audit report delivered
Stage 02

Priority sprint review

We address the highest-priority issues identified in the audit using your first month’s hours. Critical security patches applied, monitoring configured.

 

  • Critical vulnerabilities patched
  • Monitoring & alerting configured
  • Bug triage & prioritisation
Stage 03

Maintenance cycle

Your app runs on our schedule. Platform updates applied and tested. Bugs fixed as they emerge. AI integrations monitored for API changes and drift. 

 

  • Scheduled updates & testing
  • AI API version monitoring
  • Plan hours for changes & features
Stage 04

Report & review

End of each month: clear report on what was done, hours used, hours carried over, risks identified and recommendations for the next cycle. 

 

  • Monthly maintenance report

We maintain apps we didn’t build.

The majority of our enterprise maintenance clients come to us with existing applications built by another agency, freelancer or in-house team. Your previous developer doesn’t need to introduce us. We do the work of getting to know your codebase ourselves — thoroughly, before we touch anything.

01

Codebase & architecture audit

We review every layer of your application — frontend, backend, database, infrastructure and dependencies. We document what we find before making any changes.
02

Security & vulnerability assessment

We identify outstanding security vulnerabilities, outdated dependencies and unpatched components. You receive a written assessment with prioritised recommendations.
03

Handover & first-month plan

We agree on what gets fixed first, set up monitoring and communication, and begin maintenance from month one. No disruption, no big-bang changes.

In their own words

Straight from the clients whose infrastructure we run every day.
The company saved $200,000–$400,000 using EB Pearls. The team's QA services also helped the firm resolve issues by being responsive to requests and highly involved in project management. Their resources had the right technical skills; their leasing service model gave the client great flexibility.

A maintenance team that actually knows your stack.

Most maintenance providers are generalists who read your README and hope for the best. We have 360 engineers across every major platform — mobile, web, cloud and AI — who’ve shipped over 600 production applications.
01

360 engineers across every platform

iOS, Android, Flutter, Node, React, Python, PHP, AI/ML — all under one roof. When something breaks in your Swift codebase, a Swift engineer fixes it. Not a generalist. You get the right expertise for your specific stack.
02

We maintain apps we didn’t build

Every new maintenance client gets a thorough codebase audit — documented and baselined before we touch anything. We’ve onboarded complex legacy applications that other agencies refused. Difficult codebases are where we earn our keep.
03

AI maintenance is genuinely different here

We monitor LLM API versions, prompt performance and model drift as standard. Most agencies don’t. As the AI platforms your product uses evolve, your integration evolves with them — not silently breaks.
04

Hours that roll over, not disappear

On Standard and Premium plans, unused hours roll over every month. Quiet month followed by a big release? Your hours are there when you need them. No use-it-or-lose-it pressure, ever.
05

Real people on the phone

When something breaks, call 02 4005 0322 and a team member who knows your application picks up. No chatbot. No ticket queue. No re-explaining your setup every time.
06

ISO 27001 certified — independently audited

We hold ISO 27001 (information security) and ISO 9001 (quality management). Security maintenance done to a verified standard. Your application data and your users’ data handled properly.

Enterprise maintenance questions, answered

Everything you need to know before choosing a plan.

Yes — the majority of our enterprise maintenance clients come to us with existing applications built by another agency or developer. We run a thorough onboarding audit in the first week, document the codebase and architecture, identify outstanding vulnerabilities, and take over from there. No introduction from your previous developer required.

Yes. AI maintenance covers LLM API version monitoring and migration (OpenAI, Anthropic, Google, AWS Bedrock), prompt engineering updates and testing, RAG system and vector database maintenance, model performance and drift monitoring, AI feature regression testing, and AI infrastructure cost optimisation. As AI platforms evolve rapidly, ongoing maintenance is essential for any production AI feature — and most agencies simply don’t offer it.

Bug fixes correct existing functionality that is broken or behaving incorrectly — these are covered by your plan. New features add functionality that does not currently exist. New feature work uses your plan hours and we scope it before starting. If a feature request is significantly larger than your monthly hours can cover, we quote it as a separate development project.

Plans have a 3-month minimum commitment — enough time for us to properly onboard your application and show real results. After that it’s month-to-month. Cancel any time with 30 days’ notice, no questions asked. We don’t use lock-ins to retain clients. We use quality of service.

Week one: full codebase and architecture audit, security vulnerability identification, dependency review and performance baseline. We document everything before making any changes. Week two: we address the highest-priority issues using your plan hours and agree on what gets tackled first. By end of month one, monitoring is configured, communication is established and maintenance is running on our schedule.

We monitor App Store and Google Play policy changes and proactively flag anything that would affect your application before it becomes a rejection or removal. For new iOS and Android releases, we test compatibility in advance and apply required updates. If your app is rejected, we triage the reason, implement the required changes and resubmit — using your plan hours. We aim to have submissions back within 48 hours of a rejection notification.

On Standard (10 hrs/mo) and Premium (20 hrs/mo) plans, yes — unused hours roll over to future months. You build a buffer naturally and can use it when a bigger task arises. Basic (5 hrs/mo) hours do not roll over. We’ll notify you before you approach your monthly allocation so there are no surprises.

Basic ($200/mo, 5 hrs) for a stable application that needs security patch coverage and basic bug fixes. Standard ($400/mo, 10 hrs rollover) for a product that ships changes regularly and needs platform version updates (Swift, Kotlin, Flutter). Premium ($800/mo, 20 hrs rollover + QA audit) for a business-critical application where thorough QA and response time are essential. Not sure? Call 02 4005 0322 for an honest recommendation.
