When it makes sense to change the app agency

Changing the app agency is not an easy step, but sometimes necessary to get projects back on track. Typical reasons are:

• Delayed or unclear communication between customer and agency
• Incomplete documentation or lack of code transparency
• Technical debt due to poor architecture or missing tests
• Lack of scalability for new features or user numbers
• Excessive running costs or lack of transparency in billing

If you recognize your current project in one or more of these points, it's time to consider one Change of agency to think about. A project can often be quickly stabilized and optimized with clear analysis and an experienced development team.

Risks when changing agencies and how to avoid them

The most common mistake when switching is an uncoordinated transition. Without sufficient documentation, code handover and rights clearance, data, functions or integrations can be lost. That's why it's important to make the change structured and legally secure to plan.

• Ensure access to code repositories (e.g. GitLab, GitHub).
• Check server access and API keys
• Clarify contractual rights to source code and assets
• Document existing bugs and technical debt

An experienced one App agency can help to evaluate the status quo and set up a clean handover process.

Practical example: Successful agency change in 30 days

A Berlin SaaS company turned to us after the previous agency was no longer able to deliver. The project was technically unstable, build processes were flawed and deadlines were at risk. After an initial code audit, CodeGuides took over the project, set up a new GitLab setup and stabilized the application within 30 days.
