Hiring a software development company means choosing who will participate in product decisions, have access to important processes, and transform business rules into code. Portfolio and price help, but they do not alone demonstrate diagnostic capability, communication, security, and continuity.

Direct Answer: How to Choose the Company

Describe the problem and the expected outcome, select companies with compatible experience, have a technical conversation, request a comparable proposal, and check scope, team, code ownership, testing, security, infrastructure, support, and deliverables. Start with a diagnosis or a small milestone when there are still many uncertainties.

1. Prepare a Briefing That Allows for Good Responses

It is not necessary to write all the functionalities. Record:

  • who uses it and what problem they face;
  • how the process works today;
  • the outcome that will justify the investment;
  • integrations and data involved;
  • constraints on deadlines, budget, or regulation;
  • who decides and who will approve;
  • what already exists: prototype, spreadsheet, system, or code.

A responsible company will question assumptions before promising a definitive deadline. If the problem is still open, the proposal may start with discovery and prototyping.

2. Check Relevant Experience

Relevant experience does not mean having made a visually identical product. Look for similar decisions: multi-company, payments, data migration, integrations, high volume, or critical operation. Ask them to explain a project without exposing confidentiality: what was the risk, how was it reduced, what changed during the work, and how did the launch occur.

Check authorship and actual participation in the cases. An interface image does not prove that the company designed the architecture, developed, or maintained the product.

3. Evaluate the Process

QuestionWhat a clear answer should show
How is the scope defined?hypothesis, journey, priority, and acceptance criteria
How will I follow the project?demonstrations, environment, and decision logs
Who approves?responsible parties and feedback timeline from both sides
How are changes handled?impact recorded in cost, timeline, and risk
How is the system tested?strategy proportional to critical journeys
What happens next?warranty, support, evolution, or transfer

The Agile Manifesto values collaboration and working software, but it does not eliminate contracts, documentation, or planning. The process needs to make progress and risk visible.

4. Compare Proposals by the Same Scope

Separate diagnosis, design, development, infrastructure, third-party services, publishing, and support. Confirm taxes, currency, payment method, and assumptions. A proposal may seem cheap because it does not include migration, administrative panel, testing, or monitoring.

Request an explicit list of inclusions, exclusions, and client responsibilities. A deadline without availability for approval is just an incomplete estimate.

5. Ensure Ownership and Access

The contract should specify rights over code, design, documentation, and pre-existing components. Repositories, domain, cloud, database, analytics, and store accounts must be under defined control. The company needs to deliver access and avoid dependency based on operational secrecy.

Third-party libraries remain subject to their own licenses. "Code belongs to the client" does not change the license of an open framework nor authorize the redistribution of a commercial component.

6. Analyze Security and Privacy

Ask about separate environments, secrets, access review, backup, logs, dependencies, vulnerabilities, and incidents. If there are personal data, define roles and treatment instructions. The LGPD differentiates between controller and operator based on the decisions made, not just according to the name written in the contract.

7. Conduct Practical Due Diligence

  • talk to those responsible for delivery;
  • request verifiable references when available;
  • check CNPJ or contractual identity and official channels;
  • review the contract with legal support when the risk justifies it;
  • validate access to the repository from the start;
  • start with a milestone that produces something verifiable;
  • do not provide production credentials before necessary.

Warning Signs

  • fixed deadline and price before any questions;
  • promise of "any system" with unidentified team;
  • refusal to give access to the code;
  • full payment in advance without milestones;
  • use of cases that do not explain participation;
  • absence of acceptance criteria;
  • security reduced to "we use HTTPS";
  • dependence on a single account controlled by the supplier.

Visit the software development company page, compare it with the format of a freelance developer, and see how much it costs to develop a custom system.

Frequently Asked Questions

Do I need to send a ready specification?

No. A briefing with the problem, users, operation, and constraints is enough to start the diagnosis.

Is the lowest proposal the best choice?

Only if the deliverables, assumptions, responsibilities, and risks are equivalent. Compare the total cost to implement and maintain the solution in use.
