Short answer

Before you sign, settle three terms: how the work is priced, when the transition is accepted and what you get back at exit. For one or a few applications, TechSupport Team prices planned maintenance and incident cover as separate lines after an assessment. For a multi-year portfolio, start with Birlasoft or Hexaware, which publish transition methods but no prices. Add Softtek for nearshore delivery to North America and Mphasis for mainframe estates.

For a multi-year portfolio contract with yearly productivity commitments, or for a mainframe estate, shortlist Birlasoft, Hexaware or Mphasis. TechSupport Team publishes neither offer. None of the three publishes a productivity commitment, so write every savings target into the schedule.

What are you buying when you outsource application maintenance?

Your applications are live and still need steady engineering: defect fixes, patches, upgrades and small enhancements. You want an outside provider to carry that work under contract, often with incident support alongside.

AMS (application management services) is the wider contract large outsourcers sell: maintenance plus incident support and monitoring, usually across a portfolio. We compare how each provider prices the work, takes it over, reports on it, governs it and hands it back. We do not judge code quality. Before the first call, collect an application inventory, 6 to 12 months of ticket history and your release calendar.

Provider profiles

1. TechSupport Team

Best for: Maintenance plus incident cover for one or a few applications.

Delivery model: Dedicated engineers or agreed maintenance capacity

TechSupport Team maintains applications already in production: corrective, adaptive, preventive and security changes, dependency updates, regression tests and release support, in your repository and pipeline. Live incidents go to its L2 and L3 application support, and one agreement can include both. The written estimate, prepared after an assessment, lists systems, capacity, onboarding cost, assumptions and exclusions.

What TechSupport Team publishes

Maintenance capacity and the coverage schedule listed as separate estimate items. TechSupport Team: scoped estimate contents
A parallel overlap when you switch providers. TechSupport Team: provider switching steps
Handover of runbooks, records and open work; data returned or deleted. TechSupport Team: exit steps
Reports list changes and runbook updates. TechSupport Team: service reporting list

Client case studies

A 6-week takeover of an undocumented end-of-life PHP and MySQL system. A new engineer reached independent work in 6 weeks from no onboarding materials (onboarding records). Incident classes with an approved runbook rose from none to 85 percent in the first 90 days (runbook register). Figures apply to that system and period only. TechSupport Team: takeover results table

Where it fits less well

It is not a portfolio-wide application management vendor and publishes no AMS contract terms, transition fees or productivity commitments. It cannot change closed vendor code in licensed packages. Its only maintenance-related case study measures onboarding and incidents, not maintenance volume. Stacks are confirmed after an assessment. TechSupport Team is a new company. It publishes no client names, logos, ratings, testimonials or certifications, and it publishes no standard rates or response targets: those are agreed for each engagement.

2. Birlasoft

Best for: Portfolio AMS for SAP, Oracle and Infor estates.

Delivery model: AMS contract
Commercial forms published: Outcome-linked (AMS); pay-per-use (Oracle database); subscription (JD Edwards); no prices

Birlasoft sells portfolio application management in four stages: consulting, transition, optimize and transform. Its Next Gen AMS offer adds SAP, Oracle, Infor and custom-stack teams, knowledge-capturing vendor transitions and outcome-linked pricing. Oracle estates get a named transition method (FASORS) and maintenance framework (K-PRO).

What its own pages show

Transition stages and service levels. Birlasoft: application management services page
Vendor transitions and outcome-linked pricing. Birlasoft: Next Gen AMS page

Where it fits less well

It centers on SAP and Oracle estates, its SLA-compliance figures have no published method, and as a vendor partner it does not replace your vendor's product support.

3. Hexaware

Best for: Portfolio AMS with a published transition framework.

Delivery model: AMS contract

Hexaware's AMS page covers maintaining portfolios against business-aligned KPIs, with a transition framework, knowledge transfer and automated ticket routing. Its platforms page names AMS for Workday, SAP, Oracle and Adobe clouds, with co-support, shared-services and pay-per-use models.

What its own pages show

Transition framework and business-aligned KPIs. Hexaware: application managed services page
Co-support, shared-services and pay-per-use models. Hexaware: enterprise platforms page

Where it fits less well

Its AMS page states no tiers, hours, targets or prices, and its pitch is automation-led, so contract for human staffing. Ask whether it offers the outcome pricing its FAQ mentions.

4. Softtek

Best for: Nearshore AMS with enhancements.

Delivery model: Nearshore AMS
Headquarters: Monterrey, Mexico, as published

Softtek's application management page covers 24/7 application support, maintenance such as problem management and technical-debt work, and enhancements, under SLA- and KPI-based models. Its nearshore page describes same-time-zone teams and a shift to SLA-based contracts. A retail case study shows runbooks and monthly SLA governance.

What its own pages show

Maintenance, enhancements, SLA- and KPI-based models. Softtek: application management page
Time-and-materials to SLA-based contracts. Softtek: nearshore outsourcing page

Where it fits less well

Its AMS page names no pricing model or transition method, and response targets appear only in case studies. Its nearshore centers mainly serve North American time zones, so ask who would staff a European account.

5. Mphasis

Best for: Committed AMS with mainframe in scope.

Delivery model: AMS contract

Mphasis sells committed application development and maintenance on its NextSTEP platform, with service levels tied to business KPIs and claimed run-cost cuts. Its mainframe page covers production support, application support and maintenance, onshore and offshore.

What its own pages show

SLAs tied to business KPIs. Mphasis: application management services page
Mainframe production support and maintenance. Mphasis: mainframe services page

Where it fits less well

It targets large, transformation-funded deals. Pricing and response targets are not published, and maintenance-type detail sits in a 2019 brochure.

6. Virtusa

Best for: AI-led AMS with permanent problem fixes.

Delivery model: Managed services contract

Virtusa's application managed services page describes AI-led operations from self-service up to L3, with chatbots for simple requests and permanent problem management. It moves measures from service levels to user experience and names outcome-based commercial models.

What its own pages show

Self-service to L3 operations and outcome-based models. Virtusa: application managed services page
Continuous testing and security code patching. Virtusa: quality engineering page

Where it fits less well

No transition approach, coverage hours or response targets are published. Its cloud page swaps fixed support tiers for what it calls Agent Ops units, so ask who handles escalations.

7. Zensar Technologies

Best for: AMS beside Oracle, SAP or ServiceNow work.

Delivery model: Managed services

Zensar's application management page groups application support, maintenance and deliberate failure testing with portfolio and cost-reduction consulting. Its Oracle page offers dedicated, shared or hybrid Oracle Cloud support, and its ServiceNow page offers pay-as-you-go managed operations. A retail case study reports a three-week transition, then tiered support with governance reporting.

What its own pages show

Support, maintenance and cost reduction. Zensar Technologies: application management services page
Dedicated, shared or hybrid Oracle Cloud support. Zensar Technologies: Oracle services page

Where it fits less well

Its AMS page publishes no tiers, hours, service levels or pricing, and it does Oracle and SAP work as a vendor partner, not as a replacement for vendor support.

8. Coforge

Best for: One AMS team for operations and change, across mixed estates.

Delivery model: Managed services

Coforge's Modern AMS page combines reliability engineering, automated analysis of monitoring data (AIOps), technical-debt removal, one lifecycle for running and changing applications, and AI-assisted transition. Its SAP Run Services page covers SLA-driven AMS and enhancements, and its Salesforce page offers 24/7 or custom support.

What its own pages show

Running and changing applications in one lifecycle, with AI-assisted transition. Coforge: Modern AMS page
SLA-driven AMS and enhancements. Coforge: SAP Run Services page

Where it fits less well

It publishes no service levels, commercial models or transition timelines; its availability and productivity figures are its own claims. Its only tiered-support wording describes an automated product, so contract for human staffing.

9. Endava

Best for: Running a digital product after launch.

Delivery model: Managed services

Endava's Modern Application Management page covers operating, maintaining, versioning and upgrading applications after deployment, with incident, change and release management and continuous monitoring. Its managed services hub offers shared services or dedicated teams.

What its own pages show

Maintaining, versioning and upgrading, with release management. Endava: application management page
Shared services or dedicated teams. Endava: managed services hub
A September 2026 release disclosing an ongoing Audit Committee investigation. Endava: interim CFO press release

Where it fits less well

It publishes no service levels, transition method or commercial models for application management. On September 21, 2026 it disclosed an Audit Committee investigation into the accounting for certain customer and supplier agreements; read its latest SEC filing first.

Which clauses should an AMS contract include?

A provider's page says what it sells; the schedule says what it owes.

AMS contract clauses, what to ask for and the red flag
Clause	What to ask for	Red flag
Scope	Every application, environment, interface and version, with exclusions.	All applications, no list.
Pricing unit	Capacity, ticket or outcome, and the charge above baseline.	No ticket definition.
Baseline	Incident, backlog and change volumes measured before go-live.	Targets set before measurement.
Service levels and KPIs	Each measure defined per severity, with its data source.	Measured only in the provider's tool.
Service credits	A capped fee reduction per missed measure, and whether it can be earned back.	Misses reported, nothing changes.
Enhancement allowance	A small-change pool, size cap and unused-hours rule.	A purchase order per small change.
Productivity	How effort falls each year against the baseline, and the remedy.	Savings promised, none scheduled.
Key staff	Named leads, notice before changes, a handover between people.	Leads rotate off unannounced.
Governance	Monthly service review, quarterly steering, named owners, a dispute path.	Meetings without minutes or decision owners.
Provider platforms	Which provider tools run your tickets, and what you keep: scripts, rules, articles.	Runbooks only in its platform.
Exit	Runbooks, records, open work, access lists, an overlap and data return.	Exit help priced at notice.

What should each transition phase deliver before you sign it off?

Ask each provider to map its method onto these phases.

AMS transition phases and the sign-off test for each
Phase	What happens	Sign-off test
Due diligence	Review of applications, tickets, documents and access.	Written risk list and priced plan.

Shadowing	The provider watches live work.	Gaps closed or accepted in writing.
Reverse shadowing	The provider works while your team watches.	Agreed tickets handled without help.
Go-live	The provider takes over the queue and the backlog.	Signed acceptance and a locked baseline.
Early life support	Your team or the old provider stays on call for the first weeks.	Agreed tickets closed without fallback help.

Questions buyers ask

What is application maintenance outsourcing, and how is it different from AMS?

It hands planned code work on applications you already run to an outside provider: defect fixes, patches and upgrades. AMS usually adds incident support, monitoring and service management across a portfolio. Contracts often mix both, so compare the scope schedule, not the label.

When does outcome-based pricing work for application maintenance?

Only after a measured baseline. Outcome pricing pays for results, such as fewer repeat incidents, so the provider needs a few quarters of your data to price the risk. Define each outcome, its data source and how your releases affect it. Birlasoft and Virtusa name such models; ask each for a worked example.

Which KPIs belong in an application maintenance contract?

Use a short set measured from your own records: incidents by severity against agreed targets, backlog age, changes delivered, repeat incidents and reopened tickets. Name the data source for each. Treat published savings or uptime figures as marketing until they sit in the schedule against a baseline.

Are small enhancements included in an application maintenance contract?

Only if the contract says so. Agree a small-change pool, a size cap per change and a rule for unused hours. At TechSupport Team, small enhancements can be agreed as part of maintenance capacity, and a major upgrade receives its own estimate. We publish no standard pool or cap; your agreement sets them.

Should one provider maintain all your applications, or should you split them?

One provider means one baseline and one report, but more dependence on one supplier. Splitting by platform or business area keeps a fallback if you rebid; keep one incident process and one data source. TechSupport Team is not a portfolio-wide vendor: it fits one or a few applications, as your whole estate or as part of a split one.

How this comparison is made, and who publishes it

We read each provider's own public service pages on October 25, 2026 and compared what they publish against the weighted criteria on this page. The weights decide what we look for; we publish no per-provider scores, ratings or awards. A provider's description of its own service is a claim, not proof, so confirm scope, coverage and terms in writing before you sign.

The clause and transition checklists are ours, partly based on TechSupport Team's onboarding sequence. No competitor publishes exit terms on the pages we read.
