TechSupport Team provides software maintenance for applications already in production. We repair defects, update dependencies, apply security patches and make preventive changes. We test every change, and emergency fixes receive full regression tests after release.
Summary
TechSupport Team's software maintenance fits teams whose production software needs regular engineering work but not a full development team. Our engineers handle defect fixes, framework and dependency updates, patches and regression tests through your review and release process. Add dedicated engineers to your team, or agree on maintenance capacity in your estimate. Planned maintenance is separate from incident response.
Software support services cover more than bug fixes. TechSupport Team groups maintenance work into five types.
| Type | What it means | Examples |
|---|---|---|
| Corrective | Fix defects found in production. | A rounding error in invoices; a crash on empty input. |
| Adaptive | Keep the software working when its environment changes. | A third-party API version is retired; a browser changes its cookie rules. |
| Preventive | Remove risks before they cause incidents. | Add a missing index; replace code that fails under load; add alerts. |
| Security | Close known vulnerabilities. | Patch a library with a published CVE (Common Vulnerabilities and Exposures) entry. |
| Upgrades | Move to supported versions. | Upgrade an end-of-life runtime or framework version. |
Dedicated engineers can join your development or support team for maintenance work. They pick items from your backlog, follow your coding standards and submit changes for your review. See how to hire support engineers.
| Planned maintenance | Incident response | |
|---|---|---|
| Starts with | A backlog item that you prioritize. | An alert or an escalated ticket. |
| Timing | Scheduled into your release cycle. | Starts within the agreed response target. |
| Goal | A tested change that lowers future risk. | Restore service, then find the cause. |
| Testing | Full regression tests before release. | Focused checks; full tests follow in the maintenance backlog. |
| Measured by | Delivered changes and fewer repeat incidents. | Response and restoration against the service levels. |
Urgent defects can skip the queue as emergency fixes. They follow your emergency change process and receive full regression tests afterward. Live incidents are handled by application support. Use the incident severity levels template to document business impact before requesting an emergency fix.
Review the backlog with your product owner and agree on the priority of each item.
Reproduce the defect, or confirm the requirement, in a test environment.
Change the code on a branch with a test that fails before the fix and passes after it.
Run the regression suite and any manual checks agreed for the affected area.
Submit the change for review under your merge rules.
Release through your pipeline in the agreed window, then verify the result in production.
Close the item with release notes and any runbook updates.

Maintenance is planned as engineering capacity, separate from incident coverage. The pricing page explains how capacity and coverage combine. Incident terms are on the service levels page. New engagements start with the onboarding phases.
Software support usually means responding to problems. Software maintenance means changing the code to fix defects and reduce future risk. TechSupport Team handles incidents through application support and L2 (second-level) and L3 (third-level) support. This service covers planned maintenance.
Yes. We add tests around the code we change first, so each fix also adds test coverage. We report the areas without tests as risks in the regular review.
Yes, as planned maintenance. We assess the upgrade path, list the breaking changes and upgrade in stages with regression tests. A major upgrade receives its own estimate.
Your agreement sets ownership. Our changes go into your repository through your review process, like any other change.
