Maintenance · Definition
The four types of software maintenance, what maintaining a Bubble.io app involves and how to budget for it.
Last updated: October 2026. Written by Athar Ahmad, Certified Bubble.io Developer and Tech Architect, Simple Automation Solutions.
Quick answer
Application maintenance is the work of keeping software reliable, secure and useful after launch. It is commonly classified as corrective (fixing faults), adaptive (adjusting to environment changes), perfective (improving and extending) and preventive (avoiding future problems). Costs depend on change, integrations and usage, with a commonly cited rough rule of 15 to 20 percent of the build per year, plus platform and service fees. Support at Simple Automation Solutions is from $35 per hour with no retainers or minimums.
Key takeaways
- Four types: corrective, adaptive, perfective, preventive.
- No-code apps need maintenance: integrations, platform updates, privacy rules, performance.
- Budget hours monthly, plus platform, usage and third-party fees.
- Rough rules of thumb vary widely; use your own numbers after three months.
- SA Solutions support: from $35/hour, no retainers or minimums.

What is application maintenance?
Application maintenance is the work of keeping software useful, reliable and secure after it has launched. It covers fixing faults, adjusting to changes in the environment, improving features and preventing future problems. Most software spends far more of its life being maintained than being built, and no-code apps are no exception.
The four types of maintenance
| Type | Purpose | Examples |
|---|---|---|
| Corrective | Fix faults | A broken workflow, a wrong calculation, an email that does not send |
| Adaptive | Keep working as the environment changes | A plugin update, a payment provider change, a new browser behaviour, a platform update |
| Perfective | Improve and extend | New features, interface improvements, better reports, performance tuning |
| Preventive | Avoid future problems | Refactoring messy logic, reviewing privacy rules, updating documentation, removing unused items |
This four-way classification is widely used in software engineering. Most real maintenance mixes them.
What does maintenance involve for a Bubble.io app?
- Fixing issues reported by users.
- Adjusting integrations when connected services change.
- Reviewing privacy rules when roles or data change. See our security guide.
- Watching workload units and tuning slow searches. See workload units.
- Checking scheduled workflows and email delivery.
- Updating plugins and removing unused ones.
- Making small improvements requested by users.
- Keeping documentation current.
- Reviewing backups and recovery.

What does maintenance cost?
Costs depend on how much the app changes, how many integrations it has and how heavily it is used. A commonly cited rule of thumb in software is to expect maintenance to cost a meaningful fraction of the original build each year, often quoted as somewhere around 15 to 20 percent, though it varies widely and should be treated only as a rough starting point. For a no-code app, add the platform plan and usage fees, and third-party service costs.
| Cost line | Notes |
|---|---|
| Support and improvements | Billed hourly or by agreement. At Simple Automation Solutions: from $35 per hour, for hours spent, with no retainers and no minimums |
| Platform plan and usage | Paid to the platform provider |
| Third-party services | Payments, email, e-signature and AI services |
| Domain and email | Small annual costs |
| Occasional larger updates | When platforms or regulations change |
How do you plan a maintenance budget?
- List what the app depends on: platform, plugins, integrations.
- Estimate how often users will need help or changes.
- Set aside hours each month for fixes and small improvements.
- Add a buffer for unexpected issues.
- Review the budget after three months of real use.
What are the signs maintenance is being neglected?
- Small bugs pile up and are worked around.
- Nobody is sure who is responsible for the app.
- Costs rise without clear reason.
- Plugins or integrations stop working after an update.
- The app feels slower every month.
- Security reviews never happen.
- No one has looked at the documentation in a year.
Who should maintain your app?
| Option | Suits |
|---|---|
| The original developer or studio | Continuity and knowledge of the build |
| A different studio | If the first is unavailable, after a review. See our comparison of Bubble.io and custom code for platform questions |
| An in-house person | Ongoing, frequent change |
| You, for small content changes | If the app is designed to allow it |
