Outcomes Led Engineering · Maintenance

Keep your apps fast, secure,
and current.

Ongoing care that keeps applications stable, patched, and ready for the next change.

Ask AI about this service

Applications decay when no one owns them: dependencies age, store rules change, and small defects pile up. We take on maintenance with defined response times, regular patch cycles, and monitoring, so reliability is a managed outcome.

What maintenance includes.

Fixes and enhancements

Defect resolution and small improvements handled from a prioritised queue you can see.

Security and upgrades

Dependency, framework, and OS or store-requirement updates applied on a regular cycle.

Monitoring

Uptime, error, and performance monitoring with alerts routed to the right responder.

SLA-backed response

Defined response and resolution targets by severity, with monthly reporting.

Who needs it.

For teams without a dedicated owner for production applications.

Apps after launch

Continuity once the build team has moved on.

Startup · SaaS

Inherited applications

Stabilise and take over apps built by earlier vendors.

Enterprise

Store and platform updates

Stay compliant with new OS releases and store policies.

  • Fixed scope

    Scope, price, and milestones are agreed before work starts.

  • No surprises

    Weekly demos and plain-language status. Changes are priced before they are built.

  • Compliance from day one

    Dependency vulnerabilities are tracked and patched on a defined cycle, with change records kept for audit.

  • You own the IP

    Code, models, and documentation transfer to you on successful handover.

Know the price, the date,
and the exit before we start.

SLA-governed retainer. Ongoing coverage at a fixed monthly fee. Each month closes with an SLA, incident, and improvement report. The same terms are written into every statement of work for app maintenance, so there is nothing to discover later.

  • Quote Within 5 working days Price per milestone, dates, and named architect
  • Priced One fixed fee per month Third-party costs listed separately, at cost. Invoiced in USD for international clients
  • Paid On accepted working software Not on calendar dates or hours logged
  • Changes Written and priced first Cost and date impact before work starts
01 · The payment ledger

You fund accepted work, never a promise.

Drag to move through the engagement. Money is released only as each gate is accepted, so what you have paid never runs ahead of what you can use.

02 · The stress test

When something goes wrong, who pays?

Every project meets surprises. What matters is who carries them. Pick one and compare how three commercial models respond.

Time & materials

The hours keep running while the team investigates. You pay for the surprise.

Conventional fixed price

A change request is raised, usually priced at a premium and argued over.

Our contract

We verified it before quoting, and the risk register held an allowance. Any overrun beyond it is ours.

03 · The anatomy of the price

One price, built in the open.

The proposal itemises every feature or milestone, names its assumptions, and keeps a risk register with allowances. Allowances you never use are not billed.

What moves the price
  • How measurable the outcome is
  • Baseline data availability
  • Number of milestones and gates
  • Systems touched on the way
Assumptions written into the SOW (open one to see what happens if it is false)
The outcome metric and its baseline are written down in week one.

If falseWe re-baseline together before the first milestone is built.

The person who signs acceptance is named in the SOW.

If falseAcceptance delays move dates, never the fixed price.

Dependencies on your teams are listed with dates.

If falseA missed dependency is flagged the same day, with the date impact.

Billed at cost, never marked up

Technology

Built on a production-grade stack.

What buyers ask before they commit.

Straight answers on timelines, price, risk, and ownership, the same terms that appear in every proposal.

01What is App Maintenance?

App maintenance services: ongoing bug fixing, security patching, dependency upgrades, performance tuning, and monitoring for web and mobile applications.

02How quickly does App Maintenance deliver a first result?

A risk assessment and patch plan in 1 week. Typical milestones are Day 3: applications inventoried and access set up; Day 7: risk assessment and prioritised patch plan delivered; Day 30: first patch cycle complete with monitoring and SLA reporting live. Exact dates are written into the statement of work before you commit.

03How is App Maintenance priced?

SLA-governed retainer: one fixed fee per month, agreed up front. Ongoing coverage at a fixed monthly fee. Each month closes with an SLA, incident, and improvement report. Cloud hosting, licences, and usage costs are passed through at cost. International clients are invoiced in USD. The main price drivers are how measurable the outcome is, baseline data availability, number of milestones and gates, systems touched on the way.

04What happens if the scope changes or the work overruns?

The monthly fee stays fixed. Priorities can change between cycles, and any change that affects cost or the agreed service levels is quoted in writing before it is made. Extra effort needed to meet the agreed outcome is ours to carry.

05Who owns the code, models, and documentation?

You do. Code, models, and documentation transfer to you on successful handover. Code, architecture documents, deployment scripts, and credentials transfer on payment, with no licence back.

06How are security and compliance handled?

Dependency vulnerabilities are tracked and patched on a defined cycle, with change records kept for audit.

07Do you work with clients outside India?

Yes. We are based in Noida and work with clients around the world, delivering remotely. Calls and demos are scheduled in your time zone, proposals and contracts are in English, international clients are invoiced in USD, and every engagement follows the same fixed-scope terms regardless of where you are.

08When would you decline to fix a price?

If the scope is not yet defined, we do not guess a number. We propose a short, time-boxed discovery with its own fixed price, then quote the build.
