How to Choose a Software Development Partner (Without Getting Burned)

"They seemed so good in the sales call. Now it's month 4, we're 3x over budget, and the product barely works."

We hear this story weekly from companies who hired the wrong development partner.

Here's your guide to avoiding that nightmare.

Red Flags (Run Away)

1. "We Can Build Anything"

What they mean: "We don't understand your specific needs well enough to say no."

Good developers know their limits. If an agency claims expertise in blockchain AND AI AND IoT AND gaming AND fintech AND healthcare, they're probably mediocre at all of them.

Green flag: "We specialize in X and Y, but we partner with specialists for Z."

2. "We Need 50% Upfront, Rest on Completion"

The problem: Zero incentive to finish or deliver quality.

We've seen agencies take the deposit, deliver garbage, then disappear.

Green flag: Milestone-based payments tied to deliverables (25% kickoff, 25% design approval, 25% feature completion, 25% launch).

3. "We'll Estimate After You Pay Us"

Translation: "We have no idea how long this takes."

Legitimate agencies can estimate based on requirements. Vague estimates mean inexperience or intentional underpricing to win the contract.

Green flag: Detailed breakdown of features, hours, and costs before you commit.

4. "Our Developers Are in [Country] But We're Based Here"

Why it matters: Nothing wrong with offshore development IF management is competent. But "we're just the sales team" means communication nightmares.

Questions to ask:

"Who's my day-to-day contact?"
"What timezone are they in?"
"Can I meet the actual developers?"

Green flag: Direct access to development team, regardless of location.

5. "We Don't Show Work in Progress"

What they're hiding: Either nothing is being built, or what's being built is wrong.

Green flag: Weekly demos, daily access to staging environment, transparent progress.

6. "Trust Us, We're Experts"

When they deflect questions with "technical jargon" or "you wouldn't understand," run.

Green flag: They explain technical decisions in plain English and welcome your questions.

7. "We Use Our Proprietary Framework"

Translation: Vendor lock-in. You can never leave them.

Green flag: Open-source, industry-standard technologies that any developer can maintain.

Green Flags (Good Signs)

1. They Ask About Your Business, Not Just Features

Good partners understand:

Who your customers are
What problem you're solving
How you'll make money
What success looks like

Red flag: They just ask "what features do you want?"

2. They Push Back on Bad Ideas

"I don't think you need that feature" is a green flag, not a red one.

Yes-men agencies build whatever you ask for, even if it's wrong. Good partners challenge assumptions.

3. They Show Real Work

Actual code samples
Live products they've built
Client references you can call
Case studies with metrics

Red flag: Only show pretty mockups and generic "we built an app for healthcare/fintech/etc."

4. They're Transparent About Risks

"This might take longer than expected because..." "The main risk here is..." "We haven't built this exact thing before, but..."

Honesty about risks beats over-confidence.

5. They Have a Clear Process

How requirements are gathered
How progress is tracked
How changes are handled
How issues are resolved

Red flag: "We're agile so we figure it out as we go" (that's not how agile works).

Questions to Ask (And What to Listen For)

About Their Team

Q: "Who will actually work on my project?" Good answer: Names, experience levels, their expertise. Bonus: You can meet them. Bad answer: "Our team of senior developers" (generic, vague).

Q: "What's your developer turnover rate?" Good answer: <15% annually. Bad answer: They don't know, or it's >30%.

Q: "Can I review developers' resumes?" Good answer: Yes, here they are. Bad answer: "We can't share that" or send generic/fake profiles.

About Their Process

Q: "How do you handle scope changes?" Good answer: Clear change request process, documented, priced before work begins. Bad answer: "We're flexible, we figure it out."

Q: "What if I'm unhappy with the work?" Good answer: Specific revision process, quality guarantees, money-back scenarios. Bad answer: "That never happens" or vague promises.

Q: "How do you handle delays?" Good answer: Transparent communication, revised timeline, possibly adjusted pricing. Bad answer: "We're always on time" (lie) or "that's your responsibility."

About Technology

Q: "Why are you recommending this tech stack?" Good answer: Detailed reasoning tied to your specific needs, timeline, budget, team. Bad answer: "It's what we know" or "it's the best."

Q: "Can my team maintain this code?" Good answer: Yes, it uses standard technologies. Here's our documentation process. Bad answer: "You'll need us for maintenance."

Q: "What happens to the code ownership?" Good answer: You own everything, full rights, code repository access from day one. Bad answer: "We maintain ownership" or "we'll transfer it at the end."

About Past Projects

Q: "Can I talk to 3 references?" Good answer: Yes, here are their contacts. (And they actually answer and say good things.) Bad answer: "We can't share client information" or give you fake/unhelpful references.

Q: "What was your biggest project failure and what did you learn?" Good answer: Specific example, honest about mistakes, clear lessons learned. Bad answer: "We don't fail" or deflect the question.

Q: "Can I see code from a similar project?" Good answer: Yes (sanitized/anonymized if needed), or at least architecture diagrams. Bad answer: "Everything is NDA'd."

Cost and Timeline Questions

Q: "What's your hourly rate?" Common rates (US):

Offshore ($25-$50/hour)
Nearshore ($50-$100/hour)
Onshore ($100-$200/hour)

Too cheap = likely inexperienced or bait-and-switch. Too expensive = you're paying for overhead, not talent.

Q: "What's included in your estimate?" Should include:

Development
Testing
Deployment
Bug fixes (first 30 days)
Documentation

Not usually included:

Design (if you don't have it)
Third-party service costs (AWS, APIs)
Major scope changes

Q: "What happens if you go over budget?" Good answer: Fixed price or not-to-exceed cap with documented exceptions. Bad answer: "We bill hourly, whatever it takes."

The Portfolio Test

Ask to see 3 recent projects. Evaluate:

Code Quality

If they share code:

Is it readable?
Are there tests?
Is it documented?
Does it follow best practices?

If they won't share code: Red flag.

Live Products

Visit the live applications:

Do they work well?
Are they fast?
Good UX?
Still being maintained?

If they only show screenshots: Red flag.

Client Outcomes

Ask about results:

Did it launch on time?
Within budget?
Is it still in use?
Did it achieve business goals?

If they only talk about features: Red flag.

The Contract Test

Before signing, review for:

Must-Haves

Detailed scope of work
Timeline with milestones
Payment schedule tied to deliverables
IP ownership (you should own everything)
Termination clause
Bug fix guarantee (30-90 days typical)

Red Flags

Vague deliverables
Large upfront payment
They retain code ownership
No termination clause
Open-ended timeline
"Time and materials" with no cap

Size Matters

Freelancer ($10K-$40K)

Pros: Cheap, direct communication, flexible Cons: Limited capacity, single point of failure, slower Good for: Simple projects, MVPs, budget-conscious startups

Small Agency 5-15 people ($25K-$100K)

Pros: Affordable, still nimble, can handle complexity Cons: Limited simultaneous projects, may lack specializations Good for: Most projects, ideal sweet spot for startups

Large Agency 50+ people ($100K-$500K+)

Pros: Resources, specialists, enterprise processes Cons: Expensive, slower, bureaucratic Good for: Enterprise projects, complex systems, post-Series B

Our sweet spot: 10-person teams. Big enough for expertise, small enough for speed.

The Gut Check

After all the analysis, trust your gut:

Good Feelings

They listen more than they talk
They ask smart questions
You feel understood
Communication is clear
They're enthusiastic about your project

Bad Feelings

Pushy sales tactics
Over-promise results
Dismissive of your concerns
Communication is confusing
They seem bored or disinterested

Your instinct matters.

The Trial Project

Before committing to a $100K+ project, consider:

Option 1: Paid Discovery ($5K-$15K, 1-2 weeks)

Detailed requirements
Architecture design
Accurate estimate
No obligation to proceed

Option 2: Proof of Concept ($15K-$30K, 2-4 weeks)

Build one core feature
Test their competence
Validate communication
Decide whether to continue

Why it's smart:

$15K lesson vs $100K mistake
See their actual work quality
Test the relationship
Get valuable deliverables even if you switch
