Hiring a software development company is one of the higher-stakes vendor decisions a business makes. The switching costs are high — if you pick the wrong shop, you’ve spent money, you’ve lost time, and you may end up with code that’s difficult or impossible for the next team to work with.
I’ve seen this from both sides. I’ve cleaned up after bad development shops. I’ve also seen businesses set up their own engagements for failure by not knowing what they were buying. Here’s what I’d tell a business owner who’s never done this before.
What You’re Actually Buying
Software development is an expertise purchase. You’re not buying a tangible product you can inspect before you pay for it — you’re buying someone’s ability to solve a problem and build something that doesn’t yet exist.
That makes vetting hard. The demo of a past project looks impressive in a sales call. Whether that team can solve your specific problem, communicate through ambiguity, and hand off something maintainable at the end — that’s harder to evaluate.
This is why most of the vetting advice you’ll find online focuses on portfolio and pricing, and most of it isn’t the useful part.
What Actually Predicts a Good Outcome
The fit between your problem and their experience. A team that’s built 10 e-commerce platforms might not be the best choice for a manufacturing operations tool. Not because they’re bad, but because domain familiarity matters. They’ll ask better questions, anticipate problems you haven’t thought of, and spend less of your budget getting up to speed.
Look at what they’ve actually built, not just what they say they can build. “We do everything” is a yellow flag. Every good development shop has areas where they’re genuinely strong and areas where they’re adequate at best.
Their discovery process. Before any good team writes a line of code, they should be asking a lot of questions. How do you currently do this? Who are the users? What does success look like in six months? What’s the biggest risk to this project?
If a firm is eager to get to the proposal before they understand your business, they’re not going to build the right thing. Discovery is the work. Rushing it means they’re selling you a product, not solving your problem.
Their communication norms. More than almost anything else, communication determines whether a software project goes well or badly. You need to understand: How often will you see progress? How are decisions documented? What happens when scope changes? How do you flag concerns?
Ask directly: “Walk me through how a typical project works with you from kickoff to launch.” Listen for specifics. Vague answers here predict vague communication when things get complicated.
References from similar projects. Not just “can we talk to some of your clients” — specifically, “can we talk to clients who had a similar project to ours.” A reference for a marketing site doesn’t tell you much about how they’d handle a complex data integration. Ask the references targeted questions: Did the project come in on budget? How did they handle scope changes? Would you hire them again and for what kind of work?
Red Flags That Actually Matter
Scope creep without a clear change order process. Every project has scope changes. What distinguishes a professional shop is that they handle it explicitly: here’s the change, here’s the impact on timeline and budget, here’s your decision. If a firm doesn’t have a clear process for this, your initial estimate means nothing.
No testing discipline. Software without tests is a liability. Bugs get reintroduced, refactoring becomes dangerous, and you end up dependent on the original developer because nobody else understands the codebase. Ask directly: do you write automated tests? What’s your coverage standard? If the answer is vague, that’s a problem.
“We own the code” clauses. Some contracts, particularly from offshore shops, include provisions that give the development firm ownership or license rights to the code they write for you. Read the IP clauses before you sign anything. You should own the code your money pays to build.
No deployment or handoff plan. Where is the software going to run? Who’s responsible for keeping it running? What documentation will you receive? A team that doesn’t think about this until the end of the project is going to hand you something you can’t maintain.
Lowest price. Not because price doesn’t matter, but because software development is expertise and time. If the bid is significantly below the others, something is different — either the scope interpretation is different, the quality bar is different, or the team is different (often offshore junior developers sold as a senior team). Get clarity on exactly what’s being included, not just the total number.
How to Structure the Engagement
Don’t sign a fixed-price contract for a big project you haven’t fully specified. Fixed price sounds safe. It isn’t, unless the scope is airtight — and scope is rarely airtight for complex software. What usually happens is either: the firm pads the price to protect themselves, or the scope shrinks as the budget runs out, or you end up in contract disputes.
Time-and-materials with a budget ceiling is often fairer to both parties. You pay for actual work, the team has incentive to be efficient, and you have a ceiling to manage against.
Phase the work. Start with a discovery phase or a small initial scope to validate that the working relationship is functional before you commit to a large build. If the first phase goes well, you have confidence. If it goes badly, you’ve learned something at a lower cost.
Own the repository from day one. The code should live in your GitHub/GitLab organization, not theirs. You should have full access at all times. This protects you if the relationship ends for any reason.
Define “done” explicitly. What is the acceptance criteria? What tests need to pass? What performance benchmarks? What browsers? Document it before development starts so you have a shared definition of completion.
One More Thing
The best software shops will tell you when they’re not the right fit for your project. Not because they don’t want the work, but because they know their strengths and care about the outcome. If a firm seems willing to take any project regardless of fit, that’s a signal.
Good work comes from teams who give a damn about what they’re building. Interview for that.
