Hiring a software development company is one of the higher-stakes vendor decisions you’ll make. The switching costs are brutal — pick wrong and you’ve burned money, lost time, and maybe ended up with code the next team can’t even work with.
I’ve seen this from both sides. I’ve cleaned up after bad shops. I’ve also watched businesses torpedo their own projects by not understanding what they were actually buying. Here’s what I’d tell a business owner doing this for the first time.
What You’re Actually Buying
Software development is an expertise purchase. You’re not buying a thing you can inspect before you pay — you’re buying someone’s ability to solve a problem and build something that doesn’t exist yet.
That makes vetting hard. The demo looks great in the sales call. Whether that team can solve your problem, communicate through ambiguity, and hand off something maintainable at the end — that’s harder to see coming.
This is why most vetting advice focuses on portfolio and pricing. And most of it misses the point.
What Actually Predicts a Good Outcome
The fit between your problem and their experience. A team that’s built 10 e-commerce platforms might be the wrong choice for a manufacturing operations tool. Not because they’re bad — because domain familiarity matters. They’ll ask better questions, see problems you haven’t, and waste less of your budget getting up to speed.
Look at what they’ve actually built, not what they say they can build. “We do everything” is a yellow flag. Every good shop has areas where they’re genuinely strong and areas where they’re just adequate.
Their discovery process. Before any good team writes code, they should ask a lot of questions. How do you do this now? Who are the users? What does success look like in six months? What’s the biggest risk?
If they’re rushing to a proposal before they understand your business, they’re not going to build the right thing. Discovery is the work. Skip it and they’re selling you a product, not solving your problem.
Their communication norms. More than almost anything, communication determines whether a software project goes well or badly. You need to know: 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 from kickoff to launch.” Listen for specifics. Vague answers predict vague communication when things get complicated.
References from similar projects. Not just “can we talk to some clients” — specifically, “can we talk to clients who had a project like ours.” A reference for a marketing site tells you nothing about how they’d handle a complex data integration. Ask the references real questions: Did it come in on budget? How did they handle scope changes? Would you hire them again, and for what?
Red Flags That Actually Matter
Scope creep without a clear change order process. Every project has scope changes. What separates a professional shop is they handle it explicitly: here’s the change, here’s the impact on timeline and budget, here’s your decision. No 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? Vague answer? Problem.
“We own the code” clauses. Some contracts — particularly from offshore shops — include provisions that give the firm ownership or license rights to the code they write for you. Read the IP clauses before you sign. You should own the code your money built.
No deployment or handoff plan. Where is this going to run? Who keeps it running? What documentation will you get? A team that doesn’t think about this until the end is going to hand you something you can’t maintain.
Lowest price. Not because price doesn’t matter — because software development is expertise and time. If the bid is way below the others, something’s different. Either the scope interpretation is different, the quality bar is different, or the team is different (often offshore juniors sold as seniors). Get clarity on what’s actually included, not just the 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: 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 sides. You pay for actual work, the team has incentive to be efficient, and you have a cap to manage against.
Phase the work. Start with discovery or a small initial scope to validate the working relationship before you commit to a large build. First phase goes well? You have confidence. Goes badly? You learned something cheap.
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’s 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. Not because they don’t want the work — 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.
