10 Questions to Ask Before Hiring a Software Development Company

This is the most important question and the one most agencies dodge. The senior developers you met in the pitch may have nothing to do with your project day to day. Junior developers, offshore subcontractors, or rotating team members you have never met might do the actual work.

Ask for the names and experience levels of the specific people who will work on your project. Ask whether any work will be subcontracted. Ask what happens to your project if a key developer leaves during the engagement. The answers will tell you a lot.

Every agency will give you references from happy clients. Ask for a client whose project hit serious problems. How those problems were handled tells you far more about the agency than a smooth success story.

Agencies that have nothing to hide will have an answer. Those that have never handled problems honestly — or who deny that problems ever occur — are warning you.

The correct answer is: you do. Full ownership, from day one, of all source code, designs, documentation, and intellectual property. No licensing arrangements, no "you can use it but we own the IP," no dependency on the agency's proprietary tools to run what they built.

If an agency hedges on this question, do not proceed.

Scope changes are inevitable on any meaningful software project. The question is not whether they will happen — it is how they are managed when they do.

A good agency has a clear process: scope changes are documented, estimated, approved by the client, and tracked. Bad agencies either absorb changes without documentation (building resentment) or use them as an opportunity to dramatically increase the bill without transparency.

Ask for an example of how they handled a scope change on a recent project.

Software needs to be tested. Ask specifically about their QA process. Do they write automated tests? Do they have a dedicated QA team or do developers test their own work? What does the bug reporting and resolution process look like during the project?

If the answer is vague or implies that testing mostly happens at the end, that is a red flag. Testing that happens throughout a project finds problems when they are cheap to fix. Testing that only happens at the end finds problems when they are expensive to fix.

You should know what is happening on your project at all times. Ask how frequently they communicate, what format updates take, how you will track progress against the plan, and what access you have to the work in progress.

The best agencies give clients direct access to project management tools, share work continuously, and communicate proactively when something changes. The worst agencies go quiet for weeks and only surface when they need something from you or when there is a problem they can no longer hide.

Software is not done when it goes live. Bugs appear in production that were not caught in testing. Users behave in ways nobody anticipated. Infrastructure needs monitoring and maintenance.

Ask what post-launch support looks like, how long it is included, and what happens when you need a bug fixed after the warranty period. An agency that treats launch as the end of their responsibility is an agency that will be hard to reach when something breaks at 2am on a Sunday.

At INVASSO, every project includes a 12-month bug-fix warranty. We are still responsible for what we built long after it goes live.

You will not always agree with your development partner on technical decisions. What matters is how those disagreements are resolved.

The right answer is: they explain their reasoning clearly, they listen to your concerns, and decisions are made transparently with the business goals in mind. The wrong answer is: "we are the experts, trust us" with no further explanation, or alternately, "whatever you want" with no pushback regardless of whether your preference is technically sound.

Not a screenshot of a finished product — actual code, architecture diagrams, or technical documentation from a real project. You do not need to be a developer to evaluate the answer. What you are looking for is whether they can explain their technical decisions clearly, whether they value documentation, and whether they are proud of the work they do.

An agency that cannot or will not show you any technical artifacts from past projects is not a partnership — it is a black box.

Every project has risks. A development partner who tells you otherwise is either inexperienced or not being honest with you.

Ask them to name the three biggest risks in your specific project and how they plan to manage each one. The quality of this answer is one of the best predictors of project success. An agency that can articulate risks specifically — and has a concrete plan for each — is an agency that has thought carefully about your project. An agency that says the project is "straightforward" or "no problem at all" has either not thought about it carefully or is telling you what you want to hear.
