What Should App and Website Maintenance Include?

Software does not end at launch. Apps and websites need ongoing maintenance to stay secure, compatible and useful. A clear maintenance plan protects the investment — and knowing what to expect prevents surprises in the first year.

Shared maintenance tasks

• Bug triage — prioritising and fixing defects that surface in real use
• Dependency updates — keeping libraries and frameworks current and secure
• Availability monitoring — knowing when the product is down or slow
• Backups and restoration checks — confirming data can be recovered
• Content updates — editing text, media and information as needed
• Compatibility testing — verifying behaviour on new devices and browsers
• Analytics review — understanding how the product is used

Mobile-specific maintenance

• Operating system updates and their effect on the app
• App store compliance and review changes
• Push-notification and background-behaviour changes
• Device and screen-size coverage as new hardware appears

Website-specific maintenance

• Browser updates and responsive behaviour
• Content management and SEO health
• Hosting, caching and performance
• Forms and enquiry delivery — making sure enquiries actually arrive

A responsibility table

The table below is a planning example, not a promise of a particular service agreement. Use it to decide who owns each task — your team, a partner, or a platform provider.

1. 01Availability monitoring: provider or partner — 24/7 or business hours depending on agreement
2. 02Backups: whoever controls the infrastructure
3. 03Dependency updates: the development team
4. 04Content updates: usually the client's team via the CMS
5. 05Compatibility testing: the development team
6. 06Security patches: the development team, coordinated with providers
7. 07Feature requests: project-by-project, outside routine maintenance

Support boundaries

Be clear about what maintenance covers and what it does not. Routine maintenance covers keeping the existing product healthy; new features and significant changes are separate work. Agree the boundaries in writing so expectations stay realistic.

Conclusion

A sensible maintenance plan covers bugs, updates, monitoring, backups and compatibility — and defines who owns each. Plan it at the start of a project, not after launch.
