Choosing a software development company is one of the most consequential decisions a business can make. Whether you are commissioning a management platform, an e-commerce solution or a fully tailored custom software development project, the agreement you sign on day one will define your rights, your risks and your relationship for years to come. Before putting pen to paper, make sure you have asked the right questions.
Why the Contract Is More Than a Formality
Many SMEs focus heavily on the technical proposal and overlook the legal framework that surrounds it. A robust contract should clearly define the project scope, delivery milestones, payment schedule and the procedure for requesting changes. Scope creep — the gradual expansion of requirements without a corresponding adjustment in time or budget — is one of the most common sources of conflict between clients and developers. A well-structured contract anticipates this by including a formal change-request process. You should also verify that the contract specifies who is responsible for third-party licences, hosting infrastructure and ongoing maintenance once the project is delivered. If any of these responsibilities are ambiguous, ask for clarification in writing before signing.
Never assume that anything discussed verbally is binding. If it matters to your project, it must appear in the contract.
At Grupo Unifema, our custom software development service is built on transparent contracts that clearly define scope, ownership and support terms from day one — so there are no surprises once development begins.

Code Ownership
Confirm that full intellectual property rights to the source code transfer to you upon final payment. Some providers retain ownership and licence the software back to you, which limits your freedom to modify or migrate it in the future.
Source Code Access
Request that the contract guarantees delivery of the complete, commented source code in a repository you control. You should never depend solely on the vendor's infrastructure to access your own software.
Warranty and Bug-Fix Period
A reputable software development company will include a defined post-launch warranty period covering defects discovered after delivery. Understand what is included, what is excluded and how support requests are submitted and prioritised.
Maintenance and Continuity
Ask what happens if the vendor is acquired, ceases trading or ends the relationship. An escrow arrangement or a documented handover procedure protects your investment regardless of what happens to the supplier.
Questions to Ask About Guarantees and Long-Term Support
Beyond the initial delivery, you need to understand the long-term support model. Will the same team that built your system maintain it? Is there a service-level agreement that commits the provider to response times? Does the company follow documented quality-assurance and testing procedures that reduce the risk of critical bugs reaching production? These questions separate a trustworthy software development company from one that disappears once the final invoice is paid. Data protection compliance is another area to address explicitly: confirm that the development process adheres to GDPR requirements and that any data handled during the project is processed lawfully and securely.
