Your business depends on a custom software system. It may manage inventory, customer orders, accounting, deliveries, staff operations, or other daily processes. Employees rely on it, and over time it becomes an integral part of how the business operates.
Then problems begin to appear. Orders fail to save. Reports produce incorrect figures. Pages become slow, or the application starts crashing unexpectedly. The obvious response is to contact the developer who built the system.
Unfortunately, they no longer answer your calls or messages.
This situation is more common than many business owners realise.
A wholesale distributor in Douala experienced this after the developer who built their inventory system became unreachable. The software itself was still running, but the business did not have access to the source code, hosting account or server credentials. Before anyone could repair the application, they first had to recover ownership of the infrastructure supporting it.
Situations like this demonstrate that maintaining software is only part of the challenge. Ownership and access are equally important.
Before hiring another developer, it is worth understanding exactly what your business controls and whether the existing system can realistically be maintained.
Paying for Software Does Not Always Mean You Own It
Many business owners assume that once they have paid for a custom application, they own everything associated with it.
That is not always the case.
A business should have control over the assets required to maintain and operate its software. Without them, replacing a developer becomes significantly more difficult.
The first asset to verify is the source code.
The source code is the complete set of instructions that defines how the application works. If the only copy exists on a former developer's computer or personal GitHub account, your business owns the software only in a practical sense. You may have a working application, but you cannot modify, repair or extend it without recovering the original code.
Access to technical accounts is equally important.
Your organisation should control the hosting environment, database credentials, domain name, source code repository, email services and payment integrations. If your business accepts mobile payments, this also includes MTN MoMo and Orange Money accounts together with their API credentials.
Without access to these services, even experienced developers may be unable to diagnose or resolve technical problems.
Understand the Technology Before Making Decisions
The technology used to build your application has a direct impact on its long-term maintenance.
Applications built with widely adopted frameworks and technologies are generally easier to support because more developers understand them. Modern frameworks such as Laravel, for example, provide clear conventions, strong documentation and an active developer community.
Older or unsupported technologies present a different challenge. Finding engineers who still work with them becomes more difficult over time, increasing both maintenance costs and business risk.
Understanding the technology stack helps determine whether maintaining the existing application remains practical.
Repairing the System Is Often the Better Investment
Many businesses assume that replacing the original developer automatically means replacing the software as well.
That is rarely the first option an experienced engineer considers.
A well-designed system can often continue serving the business for many years with targeted improvements. If the core business processes still function, repairing the existing application is usually faster, less disruptive and more cost-effective than starting from scratch.
This is particularly true when employees already understand how the software works and the application supports day-to-day operations successfully apart from a few recurring issues.
Rebuilding an entire system should usually be considered only when the existing software has reached the limits of what it can reasonably support.
When Rebuilding Makes Sense
Some applications eventually become too expensive or risky to maintain.
This often happens when the software is built on obsolete technology, lacks a clear structure or has accumulated years of changes without proper engineering practices. In these situations, even small modifications begin affecting unrelated parts of the application.
Business growth can also expose architectural limitations.
A stock management system originally built for a single warehouse may struggle once the business expands to multiple branches, introduces online ordering or integrates with external partners. The software may continue working, but the underlying design no longer reflects how the organisation operates.
In these cases, rebuilding the application may reduce long-term costs and create a more reliable foundation for future growth.
Protect the Business Before Any Changes Are Made
Once a new developer is involved, the priority should be protecting the existing system rather than making immediate changes.
A complete backup should be created before any work begins. This includes the database, uploaded files, configuration settings and supporting documents. Development should take place on a copy of the application, allowing problems to be investigated without interrupting normal business operations.
Rushing directly into development increases the risk of introducing additional problems before the existing ones are fully understood.
Start With an Independent Technical Assessment
Rather than asking a new developer to fix every issue immediately, begin with an assessment of the system.
A proper review should answer several important questions.
-
How is the application structured?
-
What is causing the reported problems?
-
Which parts can be repaired safely?
-
Which components may require replacement?
-
What are the expected costs, risks and implementation timeline?
This assessment provides a technical basis for future decisions instead of relying on assumptions.
It also protects the business from paying for unnecessary work. In many cases, organisations discover that a relatively small number of targeted improvements can resolve problems that initially appeared to require a complete rebuild.
Evaluate the Developer Before Handing Over the Entire System
Every engineer approaches an unfamiliar codebase differently.
Experienced developers usually spend time understanding the existing architecture before proposing major changes. They identify how the software operates, review dependencies and evaluate the risks involved before recommending a course of action.
One practical way to assess a new developer is to begin with a limited piece of work.
Repairing a report, correcting a calculation or improving a search function provides an opportunity to evaluate both technical ability and communication before larger responsibilities are assigned.
If the first recommendation is to discard the entire application without a detailed review, it is reasonable to ask how that conclusion was reached.
Avoid Depending on One Individual
Many businesses only discover weaknesses in their software management after the original developer becomes unavailable.
Reducing that risk does not require technical expertise. It requires good operational practices.
Maintain copies of your source code. Keep ownership of your hosting, domain and business service accounts. Store credentials securely, create regular backups and document important systems. Work with developers who are comfortable giving your business visibility into how the software is managed rather than making themselves the only person who understands it.
These practices make future maintenance easier regardless of who provides technical support.
Make Decisions Based on Facts, Not Urgency
When business software begins failing, there is understandable pressure to restore normal operations as quickly as possible.
However, making decisions without understanding what you own, how the application is built and whether it can realistically be repaired often leads to unnecessary costs.
Many existing systems can continue serving a business for years with the right architectural improvements and ongoing maintenance. Others have reached the point where rebuilding is the responsible long-term decision.
The important step is determining which situation applies before investing significant time and money.
A structured technical assessment provides that clarity. It allows business owners to understand the condition of their software, identify ownership risks and make informed decisions based on evidence rather than assumptions.
