The Real Cost of No Support Plan

An app's life doesn't stop at the moment it's released. What happens next determines whether it grows or decays.

01

60 to 70% of Total Cost

Industry research puts the total cost of software ownership at approximately 60 to 70% in post-launch maintenance, compared to the initial development investment. A product that launches without a support plan in place will spend that budget reactively, on emergency fixes, unplanned downtime, and user churn, instead of on planned improvements that grow the product.

02

Reactive vs. Proactive

Most support vendors only offer reactive maintenance: they fix what breaks. TMS handles both reactive and proactive support from the same team. That means incidents get resolved quickly, and patterns in those incidents feed preventive work that stops the next incident before it reaches your users.

02

What's Included

Six types of maintenance and enhancement, all from one engineering team. Most vendors cover two or three. TMS covers all six.

Corrective Maintenance

Bug identification, root cause analysis, hotfixes, and regression testing. Covers production incidents, reported errors, and crash investigation.

Adaptive Maintenance

Keeping the application compatible with a changing environment: new OS versions, API deprecations, browser updates, third-party service changes, and platform policy updates.

Perfective Maintenance

Improvements that make the application better without fixing a bug: performance optimization, database query tuning, UX refinements, code refactoring, and technical debt reduction.

Preventive Maintenance

Security patches, dependency version updates, infrastructure hardening, SSL renewals, and proactive monitoring, all before issues reach your users.

User Support

End-user helpdesk assistance, onboarding documentation, how-to guides, and support ticket triage for your users and internal team.

Feature Enhancement

New functionality scoped and developed post-launch based on user feedback and product roadmap priorities. This is the "enhancement" half of the service, and it is what separates TMS from pure support vendors.

03

SLAs & Response Times

Every support engagement starts with agreed response targets. Here are the defaults. Your agreement is customized during onboarding.

Critical

Within 2 Hours

Production environment down, all users affected.

High

Within 8 Hours

Core feature broken, significant users affected.

Medium

2 Business Days

Non-critical bug, workaround exists.

Low

5 Business Days

Minor UI issue, cosmetic bug.

Enhancement

5 Business Days

New feature request scoped and estimated.

Response targets are confirmed in your support agreement during onboarding. Out-of-hours coverage is available for critical incidents by arrangement.

04

How We Get Started

A buyer with an existing application built by another team will wonder: how does TMS learn my codebase? Here is the answer.

01 · Week 1

Codebase Review

Audit existing code, infrastructure, integrations, and issue backlog.

TMS engineers audit the existing codebase, infrastructure setup, third-party integrations, and known issue backlog. You receive a technical health report with risk areas flagged before support begins.

02 · Week 1-2

Knowledge Transfer

Documentation gaps filled, architecture diagrams created.

Gaps in existing documentation are identified and filled. Architecture diagrams, deployment processes, and critical system flows are documented before support formally begins.

03 · Week 2

Monitoring Setup

Error tracking, uptime monitoring, performance alerting.

Error tracking, uptime monitoring, and performance alerting are configured to match agreed SLA thresholds. You get visibility into system health before the first ticket is filed.

04 · Week 2

Channel Setup

Ticketing workflow, escalation paths, communication tools.

Communication channels, ticketing workflow, and escalation paths are established in Jira, Linear, Slack, or your existing tools. No new tooling forced on your team.

05 · Month 1

Stabilization

Known issues resolved, tech debt assessed, roadmap drafted.

The first 30 days operate as a stabilization sprint. Known issues are resolved, technical debt is assessed, and a maintenance roadmap is drafted for the months ahead.

If TMS built the application: steps 1 and 2 take hours, not weeks. The team already knows the system, and support starts on day one.

05

06

Why Outsourced Support Helps

Nine reasons companies choose outsourced support over building an in-house team for their post-launch application.

01

Manage Costs Without Sacrificing Quality

Building an in-house support team for a post-launch application typically costs 2 to 3x the price of an equivalent outsourced engagement when you factor in salaries, benefits, onboarding time, and tooling. TMS support retainers give you a predictable monthly cost and access to a full engineering bench, not a single engineer who becomes a single point of failure when they take a vacation.

02

Maintain User Trust and Satisfaction

Users who hit a bug and get a fix within hours stay loyal. Users who hit a bug and hear nothing for a week leave. A dedicated support team ensures your users always get a response from someone who can actually resolve the issue, not a frontline agent who escalates into a void.

03

Develop What Users Actually Need

Support tickets are the most honest product research you will ever get. Every ticket tells you what your users are trying to do and where the product is stopping them. TMS captures those patterns and feeds them back as feature recommendations, turning reactive support into proactive product evolution.

04

Free Your Internal Team for New Initiatives

If your developers are fixing production bugs, they are not building your next release. Outsourced support takes the maintenance burden off your internal team so they can focus on new product development, while TMS handles the operational stability of what is already live.

05

Access a Full Engineering Bench

A single in-house support engineer handles what they know. TMS gives you access to 40+ engineers across frontend, backend, DevOps, and QA. When an issue requires a specialist, the specialist is already on the team, not a hiring req you need to open.

06

Scale Up or Down Without Hiring Pain

Hiring takes months. Firing takes longer and costs more. With a TMS support retainer, you scale hours up when a major release lands and scale down when the product stabilizes. No recruitment fees, no severance, no notice periods.

07

Get Predictable Monthly Costs

Retainer-based support means you know exactly what maintenance costs each month. No surprise invoices, no billable-hour creep, no budget approval needed for every minor fix. The number on the proposal is the number on the invoice.

08

Keep Your Codebase Healthy

Technical debt compounds silently. Without dedicated maintenance, small shortcuts become structural problems that eventually block new features entirely. TMS allocates time in every retainer for refactoring and dependency updates, keeping the codebase in a state where new development stays fast.

09

Stay Compatible With a Changing World

Browsers update, APIs deprecate, OS versions drop support for legacy code. An application that worked perfectly at launch will break without adaptive maintenance. TMS tracks these changes and updates your application before they reach your users, not after the support tickets start rolling in.

07

Why TMS for Support

What separates TMS from generic support vendors and freelance developers.

01

No Knowledge Transfer Cost If TMS Built It

Support starts on day one with full codebase familiarity, not after a 4 to 6 week ramp-up. The engineers who wrote the code are the ones maintaining it. Every architectural decision, every edge case, every workaround is already in their heads.

02

Full-Stack Team, Not a Single Developer

Frontend, backend, DevOps, and QA all available within the same engagement, without you managing multiple vendors. When a production issue spans the database, the API, and the frontend, one team handles the whole chain.

03

Enhancement Is a First-Class Service

Most support vendors fix bugs. TMS can also spec, design, and ship new features from the same team, without a separate contract. Your support engagement can scale into a product development engagement without changing vendors or re-onboarding a team.

04

Support Insights Feed Your Product Roadmap

Patterns in user issues are documented and surfaced as product improvement recommendations, turning support data into strategic input. Your monthly report does not just list what was fixed. It tells you what to build next.

05

Senior Engineers by Default

40+ engineers with 7+ years average experience. You are not assigned to a junior developer. Escalations reach senior engineers by default, and complex issues are resolved by people who have seen them before in production, not on a tutorial.

08
