Commissioning a custom software development project is one of the most consequential technology decisions your business can make. Yet many SMEs sign contracts without fully understanding who will own the resulting code, what happens if bugs appear after launch, or what their legal position is if the relationship breaks down. This guide walks you through the critical questions you must ask any software development company before you put pen to paper — covering contracts, intellectual property, and post-delivery guarantees.
Why the Contract Is the Foundation of Your Project
A well-drafted contract is not a formality — it is the legal blueprint that defines responsibilities, timelines, deliverables, and recourse if things go wrong. When evaluating a software development company, start by scrutinising the contract structure before discussing features or technology stacks. Look for a clear scope of work that describes exactly what will be built, with measurable acceptance criteria for each milestone. Ambiguous language such as 'the application will be user-friendly' is meaningless in a dispute; specific, testable criteria are not. Check whether the contract uses fixed-price, time-and-materials, or milestone-based billing, and understand the implications of each model for your budget and risk exposure. Fixed-price models give cost certainty but can lead to reduced scope if requirements grow; time-and-materials arrangements offer flexibility but require rigorous oversight. Also confirm the process for change requests: every modification to the original scope should follow a documented change-order procedure, including impact on cost and schedule. Without this, scope creep can erode your project budget silently. Finally, verify that the contract specifies a realistic dispute-resolution mechanism — whether mediation, arbitration, or jurisdiction clauses — so that disagreements can be resolved without immediate litigation.
A contract that protects only the developer is not a partnership — it is a liability. Insist on balanced terms that give your business the rights and recourse it deserves.
At Grupo Unifema, our custom software development engagements are always backed by transparent contracts with clear IP assignment, defined acceptance criteria, and structured warranty periods — so your business is protected from day one.

Intellectual Property Assignment
Confirm in writing that full IP rights transfer to your company upon final payment. Some contracts default to licensing rather than ownership, meaning the developer retains the right to reuse your code. Demand an explicit assignment clause covering source code, documentation, and any proprietary frameworks created for your project.
Source Code Access and Escrow
You should always receive the complete, documented source code — not just a compiled application. Ask whether the company uses a code escrow service if you want additional protection against business closure. Also confirm your right to audit the repository throughout development, not just at handover.
Warranty and Bug-Fix Periods
A reputable software development company will offer a post-launch warranty period during which defects discovered in the delivered scope are fixed at no additional charge. Understand the exact duration, what qualifies as a warrantable defect versus a new feature request, and the response-time SLAs for critical versus minor issues.
Maintenance, Support and Exit Clauses
Clarify what happens after the warranty expires. Is ongoing support included or separately priced? Check that the contract includes a smooth-exit clause: if you decide to switch providers, you are entitled to all documentation, environment credentials, and deployment instructions without additional fees or delays.
Additional Questions That Separate Strong Partners from Risky Vendors
Beyond the core contract terms, there are several other areas that reveal the maturity and trustworthiness of any software development company you are considering. Ask about their data protection obligations: any project involving personal data must comply with GDPR, and the contract should include a Data Processing Agreement (DPA) if the developer will handle such data on your behalf. Enquire about their use of third-party libraries and open-source components. Open-source is not inherently risky, but certain licences — such as GPL — can impose conditions on your own software distribution. A transparent developer will provide a software bill of materials (SBOM) detailing every dependency and its licence. Request a clear definition of the testing and quality-assurance process. Automated testing, user-acceptance testing protocols, and performance benchmarks should all be contractually defined, not left to informal agreement. Ask who is responsible for hosting, infrastructure provisioning, and deployment pipelines — and whether those responsibilities transfer to you at project end. Finally, check references. A credible software development consultancy will readily provide case studies or client contacts who can speak to how disputes, delays, and post-launch issues were handled in practice. How a company behaves when things go wrong tells you far more than any sales presentation.
