Software Maintenance Costs: What to Expect After Launch

Software doesn't stop costing money after launch. Here's what ongoing maintenance really looks like.

Types of Maintenance

Corrective (Bug Fixes)

Fixing issues discovered after launch. Expect higher costs in the first few months.

Adaptive (Environment Changes)

Updates for new OS versions, browser updates, third-party API changes, security patches.

Perfective (Improvements)

Performance optimisations, UX improvements, new features based on user feedback.

Preventive (Future-Proofing)

Code refactoring, documentation, addressing technical debt before it becomes critical.

Typical Costs

Industry standard: 15-20% of initial development cost annually for maintenance.

Example: £50,000 project = £7,500-10,000/year maintenance
