Application managed services run by a team you know by name

Application managed services means someone else runs your software after launch. Monitoring, incident response, code fixes, patching, releases, reporting. We do it with a dedicated team assigned to your product, not a shared ticket queue. Same engineers every month, and you talk to them directly.

Common challenges

Building the software was the easy part

Six things we hear on the first call, from teams whose product is live and whose engineers are no longer free to build.

01

The team that built it moved on to the next thing. Nobody owns the running system.

02

You find out about incidents when a customer emails, not when a dashboard fires.

03

Senior engineers lose a third of the week to production noise instead of the roadmap.

04

Your provider watches the servers and will not touch the code, so every real fix comes back to you.

05

Dependency and security updates slip one quarter, then slip another.

06

Nobody can say what changed last month without rebuilding the story from Slack.

Service overview

What application managed services actually covers

Your software, kept running by engineers who can change it

We take responsibility for software that is already live. Monitoring, incident response, fixes in the application code, dependency and security patching, small enhancements, releases, and a written report every month. The scope is your application, not your office network.

Application management services usually means SAP, Oracle or Workday. Ours does not. We run custom and product software: the web app, the API, the mobile backend, the jobs behind them. If your system is something your own team built, you are on the right page. If you need an ERP practice, we will say so on the first call.

One team is assigned to your product and stays on it. Not a pool, not a rotating shift, not a level-one desk reading a script. You have their names, you meet them before the engagement starts, and you talk to them directly.

Scope

What a managed application service includes

Written into the agreement, so neither side argues about it during an incident.

In scope every month

The standing work. No per-ticket billing on any of it.

  • Uptime, error rate and performance monitoring, with alerts tuned to your thresholds
  • Incident response at the severity levels you set
  • Bug fixes in the application code, reviewed by your team before they ship
  • Dependency, framework and security patching
  • Small enhancements, config and content changes
  • Release management, including the rollback
  • A written monthly report on what changed, what broke and what we would do next

Not in scope, and we will say so early

Some of these we do elsewhere. Some we do not do at all.

  • A new product or a major rewrite. That is a build engagement, priced separately
  • Laptops, email, office network and helpdesk. That is an MSP, and we are not one
  • SAP, Oracle or Workday AMS. We do not run ERP
  • A one-off audit with nothing ongoing after it
  • Anything we cannot get repository and environment access to
Application support

Application support services, in four shapes

Application support and maintenance is one engagement here, not two line items on an invoice.

Monitoring and detection

Support starts before the ticket. Uptime, errors, latency and job failures, on dashboards you can read yourself. Alerts go to us first.

Incident response

Severity levels you define, not ones we impose. One engineer owns the incident until it closes, and anything that took production down gets a written cause.

Corrective maintenance

The fix goes into the code, not into a workaround document. Pull requests into your repositories, reviewed by your engineers, shipped on your release process.

Preventive maintenance

Patching, version bumps, certificate renewals and cleanup on a schedule. Reviewed, never auto-merged. This is the work that stops being urgent later.

Engagement models

Three ways teams buy it

Managed application support

The standard. A monthly retainer, a fixed team, and the whole running system in scope. For products with no dedicated maintenance engineer and no plan to hire one.

Co-managed

Your engineers keep ownership. We take the hours you do not want to cover, the patch backlog and the recurring noise. Useful when the team is good but stretched.

Full application ownership

For a system whose original team has gone. We start by reading it and writing down how it works, then take it over. Longer onboarding, and we will tell you that up front.

Need patches and updates but not a standing team? That is software maintenance and support. Want engineers inside your own sprints instead of a service around them? That is IT staff augmentation, and it is priced differently.

Our people

Who is actually on your account

Four roles, named before the engagement starts. Two to four engineers is the usual shape, sized to the system rather than to a package.

Role 1

Engagement lead

  • Your single point of contact, on the standing call
  • Owns the monthly report and the priority order
  • Says no to scope creep in writing, not quietly
Role 2

Application engineers

  • The fixes, the patches and the small enhancements
  • On your repositories, under your review rules
  • The same people month after month
Role 3

QA engineer

  • Regression before anything reaches production
  • Builds the test coverage the fixes keep needing
  • Verifies the rollback path, not just the release
Role 4

Reporting analyst

  • Turns the month into something you can forward
  • Tracks incident causes rather than incident counts
  • Flags the recurring problem worth fixing properly
How we work

Onboard, watch, fix, report

The first month is mostly reading. Nobody should be changing a system they cannot describe.

01
Weeks 1 to 4

Onboard and baseline

Read-only access first. We inventory the services, the environments and the owners, then write down what normal looks like so an alert means something.

NDA before any access Runbook for what exists, not what the diagram says
02
From week 4

Monitoring goes live

Dashboards and alerts on your accounts, tuned to thresholds you agree. Alerts route to us first. A noisy pager gets ignored, so we spend the first weeks quieting it.

Your cloud, your tooling, your data Severity levels set by you
03
Ongoing

Fix and ship

Everything arrives as a pull request your engineers review. Patches on a schedule, fixes on severity, enhancements in the order you rank them.

Your release process, not ours Rollback tested before it is needed
04
Every month

Report and review

One written report: what changed, what broke, what it cost, and what we would fix next. Then a call to agree the order. No dashboard tour instead of an answer.

Written cause on anything that took production down You keep every report

Tooling

We run it on your tools, not on a platform you rent from us

If you already pay for the licence, we use it. We resell nothing.

Monitoring and alerting

Datadog, Grafana with Prometheus, Sentry for application errors, PagerDuty for the rota. New Relic and Opsgenie where a team already has them.

Pipelines and releases

GitHub Actions, GitLab CI or Jenkins, whichever is already wired in. We inherit your pipeline before we propose changing it.

Runtime and cloud

Docker and Kubernetes, Terraform for anything we change underneath, on AWS, Azure or Google Cloud. Elastic for logs when that is where they already go.

Pricing

What moves the price

We scope before we price. Nobody can quote this off a web form.

The five factors that determine the monthly cost of an application managed services engagement
DriverWhy it moves the number
How many services are really in scopeOne web app and one database is a different job from eleven services, four of which nobody can name an owner for.
How much is already monitoredWorking dashboards we can extend are cheap. Starting from nothing means a month of instrumentation before an alert is worth acting on.
How deep into the code we goRestarting a service is not maintenance. Fixing the bug that caused it needs engineers who can read your codebase, and that is a different rate.
Which hours you need coveredBusiness hours in one time zone is the base. Extended cover means more engineers on the account, not the same ones working longer.
How much of it is written downAn undocumented system has to be read and described before it can be run safely. That work is real and we price it as onboarding, not hide it.
Testimonials

What clients say about working with us

Every quote below is from a verified review. None of them were written by us.

“They don’t just build what you ask for. They think about the end result, and then go beyond it.”

James Fitzgerald
CTO, computer software company

“They find the right developers fast, and actually listen when you push back. That combination is harder to find than it sounds.”

Arno Nederlof
Lead developer, healthtech company

“Clear expectations, rules that actually hold, delivered on time. And the people are genuinely easy to work with, not just professionally, but as humans.”

Honest scoping

When to call us, and when to call someone else

A good fit

  • Your product is live, has real users, and nobody owns it day to day
  • The engineers who built it have moved on, or are about to
  • You want fixes in the code, not a provider who restarts the server
  • Your roadmap keeps losing to production work
  • You need one team that knows the system, month after month
  • You want to be able to read a monthly report and forward it to your board

Not a fit

Common questions

Answered without the hedging

Not sure this is what you need?

Send the stack, roughly how many services are live, and what broke last month. We will tell you what we would take on first, including when the answer is nothing.

Book a call
What are application managed services?
Application managed services, often shortened to AMS, is an ongoing engagement where an external team runs software that is already live. The scope covers monitoring, incident response, bug fixes in the application code, security and dependency patching, small enhancements, release management and regular reporting. It is priced as a monthly fee rather than per project. The difference from general IT managed services is what gets touched: AMS works inside the application, not on the servers and office network around it.
How is this different from a managed service provider?
An MSP manages infrastructure: hosting, networks, endpoints, backups. Most will not open your repository, so anything that needs a code change comes back to your team. We are software engineers running your application, which means the fix goes into the code and ships through your normal release process. If you need both, keep your MSP and add us. We have no interest in your office network.
Do you do SAP, Oracle or Workday AMS?
No. Most application management services on the market are ERP practices, and we are not one. We run custom and product software: web applications, APIs, mobile backends and the jobs behind them, built in the stacks our engineers work in every day. If your system is something your own team built, we can run it. If it is a licensed ERP, you want a specialist and we will say so on the first call.
How fast do you respond to an incident?
We agree severity levels and response targets with you before the engagement starts, and we write them into the agreement rather than publish them here. The reason is honest: a response time is only meaningful against a defined severity and a defined coverage window, and those differ per system. What is fixed regardless is that one named engineer owns an incident until it closes, and anything that took production down gets a written cause.
Can you take over software your team did not build?
Yes, and it is a large part of what we do. Onboarding starts read-only. We inventory the services, the environments and the owners, then write down how the system actually behaves before we change anything. Expect four to six weeks before we take responsibility, longer if there is no documentation and no one left to ask. We will tell you which of those two you are in after the first look.
Who owns the code you write?
You do, all of it. Every commit, script, dashboard, runbook and report produced during the engagement is yours, assigned in the contract. Work lands in your repositories and your cloud accounts from day one, so there is nothing to hand back at the end. We keep no proprietary layer that you would need a licence to keep using.
What time zones do you cover?
The team works from Ho Chi Minh City. That gives a full working overlap with Australia and Asia, a solid afternoon overlap with Europe, and an early morning overlap with the US east coast. For teams further west we agree a staffed window rather than pretend the overlap is bigger than it is. Extended and out-of-hours cover is available and it changes the price, because it means more engineers on the account rather than the same ones working longer.
How is this different from software maintenance and support?
The line is who is accountable. Software maintenance and support is work you buy: patches, fixes and updates, scheduled or on request, with your team still owning the running system. Application managed services is ownership you delegate: we watch it, we decide what needs doing, we do it, and we report on it. If you already know what needs fixing and just need hands, start with maintenance. If nobody is watching, start here.
