Keep Your Application Working as Your Business Changes
Your application needs attention after launch. Dependencies change, users find problems, integrations need updating and your business develops new requirements.
DOT IT Services provides application maintenance and development support for existing web applications, mobile apps and business software.
Get help with defined fixes, planned improvements or an agreed allocation of ongoing development time. We start by understanding your application and the responsibilities you need covered.
Maintenance Around Your Application’s Needs
A customer-facing SaaS product needs different support from an internal reporting tool. The right arrangement depends on who uses the application, how important it is to daily operations and what your team already handles.
We discuss:
If the application’s condition is uncertain, an assessment can help establish a suitable starting scope.
Application technical assessmentWhat Our Application Maintenance Services Can Cover
Bug Investigation and Fixes
Investigate problems affecting existing functionality, from failed forms and incorrect calculations to errors in account workflows.
Useful reports include reproduction steps, affected users, expected behaviour and relevant logs. Where the cause is unclear, investigation comes before a dependable repair estimate.
Framework and Dependency Updates
Review updates to frameworks, libraries and supporting components.
Compatibility checks and testing help identify how a change could affect the application. An update should account for the existing codebase rather than assuming every version change is straightforward.
Performance Improvements
Investigate slow pages, delayed API responses, inefficient queries and other reported performance problems.
Work starts with measurements and the conditions under which the problem occurs. Improvements are assessed against that evidence.
Integration Maintenance
Maintain connections with payment providers, CRMs, messaging services and other platforms.
Changes in credentials, API behaviour, request limits or third-party availability can affect an otherwise working application. For a new connection or substantial integration change, explore our API development and integration service.
Small Improvements and Feature Changes
Make agreed changes to interfaces, reports, permissions and business workflows.
We distinguish maintenance tasks from larger feature development so priorities, estimates and budget remain clear.
Documentation and Release Support
Update setup instructions, record important dependencies and support the agreed release process.
Keeping this information current helps your team maintain continuity when responsibilities change.
Web Application Maintenance
Support an existing website application, customer portal, dashboard or SaaS product.
The scope can cover frontend behaviour, backend services and the connections between them.
React and Next.js Applications
Maintain interfaces, application state, API connections and relevant rendering behaviour.
For dedicated capacity, explore our:
Node.js Backends
Investigate API errors, integration problems and application logic within your existing backend.
If you need someone regularly working through your backend backlog, discuss our Node.js developer hiring options.
Python Applications
Maintain Python services, web applications and connected workflows.
Depending on your stack, relevant support may involve:
Looking after a CMS or content-driven site? We also provide WordPress development support for theme fixes, Elementor updates and WooCommerce maintenance.
Mobile Application Maintenance
Mobile apps need attention as operating systems, dependencies and external services change.
An agreed maintenance scope may include:
App store submission assistance, account responsibilities and release materials must be defined separately. Review timing and approval remain with the distribution platforms.
Taking Over Maintenance From Another Developer
You can discuss support for an application built by another supplier.
Before accepting ongoing responsibility, we need enough information to understand the software, its dependencies and how it is operated.
The onboarding review may cover:
Missing information becomes a visible onboarding requirement. Learn how to Transfer application knowledge and access systematically to prevent operational downtime.
If a broader transition is needed, our software project takeover service explains how we approach access, handover and the first development stage.

“Support included” can leave important questions unanswered.
Your maintenance agreement should define the application areas covered, the working hours and how requests move from reporting to resolution.
| Area | What to confirm |
|---|---|
| Coverage | Applications, environments and components included |
| Availability | Support hours, working days and exclusions |
| Reporting | Where requests are submitted and what information is needed |
| Priority | How business impact and urgency are assessed |
| Response | When a reported issue will be reviewed or acknowledged |
| Investigation | Whether diagnostic work uses the allocated hours |
| Resolution | How fixes are estimated, approved and tested |
| Releases | Who authorises production changes |
| Third parties | Which services depend on another provider |
| Additional work | How requests outside the scope are handled |
A response commitment is different from a guaranteed resolution time. The time needed to repair a problem depends on its cause, access and dependencies.
Round-the-clock monitoring or emergency cover is included only where expressly agreed.
Prioritise Work by Business Impact
A useful maintenance process distinguishes urgent disruption from planned improvements.
Critical Workflow Problems
An essential function may be unavailable or producing incorrect results.
The response follows the agreed support arrangement and available access. Immediate changes still need an appropriate review and recovery approach.
Significant Functional Issues
A feature may fail for some users or under particular conditions.
Document the affected workflow, available workaround and impact so the task can be prioritised.
Routine Fixes and Improvements
Minor defects, usability changes and non-urgent updates can be planned into the development backlog.
Scheduled during standard sprint and maintenance cycles.
Larger Development Requests
A new module, substantial integration or major redesign may need a separate scope.
Where ongoing feature development is the main requirement, a dedicated developer or full-stack developer may be a more suitable arrangement.
A Reviewable Maintenance Process
1. Record the Request
Capture what happened, the expected behaviour and any reproduction details.
2. Review the Impact
Assess the affected workflow, urgency and dependencies against the agreed priorities.
3. Investigate and Estimate
Identify the likely cause and explain the work needed. Unresolved questions remain visible.
4. Approve the Change
Confirm the scope, expected effort and acceptance criteria before implementation where required.
5. Develop and Test
Check the change against the reported issue and relevant regression risks.
6. Release and Document
Follow the agreed deployment process and record important changes or remaining limitations.
Visibility Into Maintenance Work
Agree on reporting that helps your team understand where time is going.
Depending on the engagement, updates can include:
Your team should be able to distinguish completed work from an issue that remains under investigation.
Application Maintenance Pricing
Maintenance is quoted according to the application, workload and support responsibilities.
Task-Based Support
For a defined problem, update or improvement.
Investigation may need its own scope before a repair can be estimated.
Allocated Development Hours
For a planned maintenance backlog and recurring improvements.
Agree on the hours, prioritisation process, reporting and treatment of unused or additional time.
Ongoing Developer Capacity
For applications needing regular maintenance and feature development.
The agreement defines responsibilities, availability and the development allocation.
Development starts from $25/hour. Final rates and any separate onboarding, monitoring or support fees are confirmed in your proposal.
Hosting, paid services and third-party usage charges are included only where stated.
Maintenance Support for Agency Client Applications
Agencies can discuss ongoing support for applications delivered to their clients.
Before starting, agree on:
