Who is the maintenance contract for?

For everyone whose software runs, but no longer has anyone to care for it.

Your application earns money, and exactly for that reason it must not age uncared for. The maintenance contract is the path for everyone who wants to hand over the care. It is for you if you recognize at least one of these sentences:

“The application runs stably, but nobody dares to touch it anymore.”
“Our last .NET developer retires in two years.”
“We only do updates when something is on fire. And then it gets expensive.”
“I want predictable monthly costs instead of unpredictable firefighting.”

What you get

Four services you can rely on.

Annual mandatory update

Once a year we lift your application onto the current .NET version and secure compatibility with the current operating systems. Included in all tiers.

Security & dependency updates

We roll in security and library updates regularly: quarterly in Basic, monthly in Plus and Premium. This way the update backlog that makes modernizations expensive does not even arise.

Platform monitoring

We keep an eye on advisories, certificates and platform changes and act before an outage results from them. In Premium additionally Azure monitoring including a cost check.

Budget & guaranteed response times

Depending on the tier 2, 5 or 10 hours per month for support and small changes, with a guaranteed response time: from 3 business days by email to 4 hours on business days.

How you get to the contract

Four steps to ongoing care.

1 · Clarify the prerequisite

We do not maintain any application blindly: the prerequisite is a prior Modernization Report or a comparable analysis, or your application was built by us.

2 · Choose the tier

Basic, Plus or Premium: you choose the budget, response time and proactivity that fit your application. We advise you honestly which tier is enough.

3 · Ongoing care

Security and dependency updates in a fixed rhythm, platform monitoring in the background, your budget for support and small changes.

4 · Annual cadence

The annual mandatory .NET update keeps the base current. From Plus the health check is added, and in Premium additionally the annual roadmap session with an architect.

Price in three tiers

As much care as your application needs.

We keep it running: the price applies per application up to medium size, larger applications we calculate individually. All prices net plus VAT.

Prerequisite: a prior Modernization Report or a comparable analysis, or the application was built by us. This way both sides know what they are getting into.

Where does the maintenance contract stand on the journey?

The maintenance contract is one of the two ongoing paths at the end of the Legacy to Innovation journey: we keep it running. The other path is the Architecture Sparring, where your team modernizes itself and we accompany. And the prerequisite pays into the journey: the Modernization Report (3,499.00 €) delivers not only the basis for the maintenance, but is also credited with 1,499.00 € toward a later workshop.

Honestly said

We do not maintain anything we do not know.

A maintenance contract without knowledge of the application would be a promise into the blue, and that is exactly what we do not make. That is why the prior Modernization Report or a comparable analysis is a prerequisite, unless the application was built by us anyway. This protects you from commitments that do not hold when it counts.

And one more thing belongs to honesty: maintenance preserves the state, it does not modernize. If your application is stuck deep in the maintenance trap, the maintenance contract is good protection for a while, but no substitute for the directional decision. That is what the Future-Check clarifies.

Frequently asked questions

Answered clearly.

Why do you require a Modernization Report or an analysis first?

Because we do not maintain any application blindly whose state we do not know. The report or a comparable analysis shows us the architecture, risks and dependencies, and you get realistic commitments instead of nasty surprises. If Quality Bytes built your application, this prerequisite is of course waived.

What is the annual mandatory update?

Once a year we lift your application onto the current .NET version and ensure compatibility with the current operating systems. That is included in all three tiers, because it is exactly this update that gets postponed for years in many companies, until it gets expensive.

Does the price apply to all our applications together?

No, the price applies per application up to medium size. For larger applications or several applications we create an individual proposal. Get in touch, we will tell you honestly which category your application falls into.

How fast do you react when something goes wrong?

Depending on the tier: in Basic we answer within 3 business days by email, in Plus within one business day via Teams and phone, in Premium within 4 hours on business days. On top of that comes the fixed budget of 2, 5 or 10 hours per month for support and small changes.

What does the .NET Maintenance Contract cost?

Basic 498.00 €, Plus 899.00 € or Premium 1,499.00 € per month, each net plus VAT and per application up to medium size. The tiers differ in the update frequency, in the budget, in the response time and in the proactivity: health checks from Plus, Azure monitoring with a cost check and the annual roadmap session in Premium.
