Hiring a software development company is one of the highest-stakes decisions a non-technical founder makes. Get it right and you have a technical partner who ships your product, tells you when you're wrong, and grows with your business. Get it wrong and you lose months, spend money on software that doesn't work, and end up back at the start — except now with less runway and lower confidence.
I run a software development agency. I have an obvious conflict of interest in writing this. I'm writing it anyway because the founders who approach us having done proper due diligence make significantly better clients, and because the industry has enough agencies who would rather you not know how to evaluate them properly.
This is the guide I'd want a founder to read before they contacted us.
Before you start looking: what you actually need to know first
Most founders start searching for agencies before they've answered the questions that determine which agency is the right fit. This leads to generic conversations that produce generic proposals that aren't useful for making a decision.
Answer these four questions before you talk to anyone:
What are you actually building? Not the vision — the specific software. What does it do? Who uses it? What are the three most important things a user can do with it? If you can't answer this in two paragraphs, you're not ready to hire a development agency. You're ready to hire a product consultant.
What do you have? Designs, wireframes, a technical spec, an existing codebase, or just an idea? The answer changes which agency is the right fit and significantly changes the cost and timeline of any engagement.
What is your actual budget? Not "as little as possible" — a number. Agencies scope to budgets. If you tell an agency your budget is $50,000, they'll scope a project that fits $50,000. If you hide your budget, they'll scope a project that fits what they think you can afford, which is usually more expensive than you expected and less than you needed.
What does success look like in 6 months? Not "a great product" — specific outcomes. "500 users signed up," "the logistics team uses it daily and we've eliminated two manual processes," "we've raised a seed round using the product as a demo." Specific success criteria help you and the agency know whether the project delivered.
Where to find software development agencies
There are five reliable channels. Each has different signal-to-noise ratios.
Clutch and similar directories
Clutch (clutch.co) is the most reliable directory for software development agencies. Their review system requires clients to be interviewed directly by Clutch — not just leave a star rating. This makes their reviews harder to game than most.
GoodFirms and TechBehemoths use similar verified review models. All three are worth checking.
How to use them: Filter by service (custom software, mobile app, etc.), minimum project size (use this to filter out agencies that primarily do small projects), and reviews. Read the reviews — not the star rating, but the actual text. Look for reviews that describe projects similar to yours.
What to watch out for: Agencies with many reviews from the same time period (a one-time review drive, not consistent satisfaction). Agencies with only five-star reviews and no specifics in the review text.
Referrals from founders in your network
The highest-signal channel. A founder who used an agency for a similar project and can tell you specifically what went well and what didn't is more valuable than any directory listing.
How to get referrals: Ask in founder communities (YC alumni networks, startup Slack groups, LinkedIn founder groups). Ask investors if they have recommendations from portfolio companies. Ask at events.
What to watch out for: Referrals are biased toward the relationship, not the result. A founder who likes their agency might recommend them even if the output was mediocre. Dig into the specifics: "What specifically did they do well? What would you do differently? Did they deliver on time and on budget?"
LinkedIn outreach
For agencies you discover through content, speaking, or that appear in your searches. LinkedIn gives you access to the founders and principals directly rather than going through a sales process.
How to use it: Message the agency founder or technical lead directly. Reference something specific about their work that's relevant to your project. Short messages with specific context get responses; generic "looking for a development partner" messages don't.
Google search
Less reliable than it used to be, but still useful for finding agencies with genuine organic rankings. An agency that ranks for "logistics software development company" has invested in content that demonstrates expertise in that area.
What to watch out for: Ranking on Google says nothing about delivery quality. Use it to find candidates, then verify through reviews and references.
Upwork and freelance platforms
For smaller, well-defined projects. Individual contractors on Upwork can be excellent, but you're managing individual contributors rather than working with a team that owns a project. For anything requiring multiple disciplines (design, backend, mobile) or ongoing coordination, a proper agency is usually a better fit.
How to evaluate agencies: the process that actually works
Step 1: Initial filter (before any calls)
Review every agency's website, portfolio, and Clutch profile before spending time on calls.
Eliminate agencies that:
- Have no verified third-party reviews
- Have a portfolio with nothing similar to what you're building
- Don't disclose who they are (no team page, no founder names, no location)
- Have been operating for less than 2 years
Keep agencies that:
- Have 5+ verified reviews with specific, relevant detail
- Show portfolio work in your industry or at similar complexity
- Have been operating for 3+ years (survived real challenges)
- Have transparent pricing signals (minimum project size, rate range)
You should be able to eliminate 70% of agencies in this step without a single call.
Step 2: The brief (before the first call)
Send a written brief to every agency that passes the initial filter. The brief should include:
- What you're building (2–3 paragraphs)
- What you have (designs, wireframes, spec, or nothing)
- Platform requirements (web, iOS, Android)
- Key integrations needed
- Timeline (when you need to launch and why)
- Budget range (be honest)
- What you need from them in the first meeting
What to look for in responses: How long did they take to respond? Did they read your brief (do their questions reflect what you wrote) or send a generic response? Do they ask clarifying questions, or do they immediately jump to a proposal?
A response that comes within 4 hours and contains no questions about your specific project tells you about their sales process — they're optimising for speed, not understanding.
Step 3: The first call
The first call is not a sales call. It's a mutual assessment. You're deciding whether they understand your problem. They're deciding whether your project is a good fit.
Questions to ask:
"Can you tell me about a similar project you've delivered? Specifically what the client needed, what you built, and what happened after launch?"
Listen for: specific detail (real projects have specific details), honesty about challenges, and whether the outcome was positive or they carefully avoid mentioning it.
"What's the most common reason your projects go over budget or timeline?"
Every experienced agency has an honest answer to this. If they say "that rarely happens with us," they're either very new or not being honest.
"Based on what I've told you, what's your biggest concern about this project?"
Inexperienced agencies have no concerns. Experienced agencies identify risks early.
"Who would actually work on my project? Can I meet them before signing?"
Some agencies sell you senior team members and deliver junior ones. The answer to this question tells you how transparent they are about team composition.
"What does your client communication process look like?"
Look for: specific cadence (weekly calls, daily standups, sprint reviews), specific tools (Jira, Linear, Slack, Loom), and a clear escalation path when problems arise. "We communicate openly" is not an answer.
Red flags in first calls:
- They haven't read your brief
- They pitch their capabilities rather than understanding your problem
- They have no concerns or risks to raise
- They can't introduce you to the people who would work on your project
- They give timeline and budget estimates without asking enough questions
Step 4: The proposal review
A good proposal is specific enough that both parties can be held accountable to it.
Proposals should contain:
A detailed scope — specific features, not categories. "User authentication with email/password login, Google OAuth, email verification, password reset, and 2FA" is a scope item. "Authentication system" is not.
Explicit exclusions — what's not included matters as much as what is. If the proposal doesn't list exclusions, change orders will define them later at your expense.
A milestone-based timeline — not just a final delivery date. What will be delivered at each milestone? When will you see working software?
A milestone-based payment schedule — tied to deliverables, not calendar dates. Paying significant amounts before seeing working software is a risk.
A clear change order process — how are scope changes handled? What's the process for requesting changes and what's the pricing basis for them?
Post-launch support terms — how long after launch will they fix bugs at no additional charge? What's the process for reporting issues?
Proposals that should concern you:
- Delivered within 24 hours of the first call (not enough thinking happened)
- Fixed price with vague scope (the ambiguity is where change orders come from)
- No exclusions listed
- Payment upfront or front-loaded without corresponding deliverables
- No post-launch support period
Step 5: Reference checks
Ask for two or three references from projects similar to yours. Then actually call them.
Questions to ask references:
"Did the project deliver what was originally scoped?" "Did it deliver on time and on budget? If not, why not?" "How did the agency communicate when problems came up?" "Would you hire them again? Are you still working with them?" "What would you do differently?"
A reference call that goes quickly and produces only positive answers is a reference the agency coached. A reference call that takes 20 minutes and includes some honest criticism is a real one.
If an agency can't provide references, that's a significant red flag. Agencies with satisfied clients are happy to connect you with them.
Fixed price vs time and materials vs dedicated team
The engagement model shapes the entire relationship. Choose based on your situation, not on what the agency prefers.
Fixed price: You agree on scope and price upfront. Good when requirements are well-defined and you need cost certainty. Bad when requirements will evolve or the scope isn't clear enough to actually fix.
Watch for: agencies that use vague scope in fixed-price contracts. The vaguer the scope, the more room for "that's out of scope" conversations later.
Time and materials: You pay for hours worked at agreed rates. Good for evolving products where requirements will change. Requires active client involvement to manage scope and pace.
Watch for: no budget ceiling. Set a maximum spend and require the agency to flag when you're approaching it.
Dedicated team: You retain a team of developers who work on your product consistently. Good for sustained development over 6+ months. Requires you to manage the team's workload and prioritisation.
Watch for: team rotation. A "dedicated team" that assigns different developers each month isn't dedicated.
Offshore vs nearshore vs domestic: the real trade-offs
Domestic (US, UK, AU):
- Advantages: same time zone, cultural alignment, easiest communication
- Disadvantages: highest cost, often booked out, limited talent pool in specific technologies
- Right for: regulated industries with compliance requirements around where development happens, or when budget is not a constraint
Nearshore (Eastern Europe for US/UK, Southeast Asia for AU):
- Advantages: significant time zone overlap, strong technical talent, lower cost than domestic
- Disadvantages: higher cost than South Asia, some communication overhead
- Right for: projects where time zone overlap is essential and South Asian rates aren't necessary
Offshore (South Asia — Pakistan, India):
- Advantages: significant cost reduction (40–60% vs domestic), strong technical talent in modern stacks, improving time zone management tools
- Disadvantages: real time zone gap (5–12 hours to US/UK), communication requires more discipline from both sides
- Right for: founders with enough time and project definition to manage async communication, or when budget is a real constraint
The time zone gap is real but manageable. The agencies that manage it well invest in: thorough written communication, detailed sprint planning so work is clear before execution, regular video updates, and responsive communication during overlap hours.
The agencies that manage it badly disappear for days at a time and resurface with surprises.
Contract essentials: what must be in writing
Don't start work without a written contract covering:
IP ownership: Every line of code written for your project should belong to you on final payment. The contract should say this explicitly. "Work for hire" language or explicit IP assignment clauses are what to look for.
Confidentiality: NDA or confidentiality clause covering your business information, product details, and any data you share during the engagement.
Scope definition: Reference to the agreed scope document. Changes to scope should require written agreement from both parties.
Payment terms: Milestone-based payments tied to specific deliverables. Avoid paying more than 30% upfront.
Termination rights: Your right to terminate the engagement with reasonable notice. What happens to work in progress? What deliverables are you entitled to on termination?
Warranty period: How long after delivery will the agency fix bugs at no charge? 30–60 days is standard.
Governing law: Which country's law governs the contract. This matters if something goes wrong.
If an agency resists any of these, understand why before proceeding. Some points are negotiable. IP ownership is not.
The green flags that actually matter
Most "green flag" lists focus on surface signals — nice website, quick responses, good reviews. Those are useful but not sufficient.
The signals that actually predict a good engagement:
They tell you things you don't want to hear. If an agency tells you your timeline is unrealistic, your scope is too large for your budget, or that your idea has a technical problem you hadn't considered — that's a green flag. Agencies that only tell you what you want to hear are optimising for closing the deal, not for delivering your product.
They've delivered in your specific domain. Generic software agencies can build almost anything. But an agency that has built logistics software before understands that carrier API integration is harder than it looks. An agency that has built healthcare software understands compliance requirements. Domain experience saves money on every project.
Their previous clients still work with them. Repeat clients are the strongest signal in the industry. A client who comes back for a second and third project isn't paying for hope — they're paying because the first project worked.
They push back on your requirements. A good agency asks why you need specific features, challenges scope that doesn't serve your users, and suggests alternatives to your stated approach when they know a better one. An agency that just builds what you describe, without question, is an order-taker. An order-taker won't tell you when you're about to make an expensive mistake.
One honest thing about Teamseven
We fail some of the standards in this post sometimes. We've had projects run over timeline. We've had communication gaps. We've made technical decisions we'd make differently with hindsight.
What I can say honestly: when things have gone wrong, we've acknowledged it and fixed it. We tell prospects when we're not the right fit. We've turned down projects that weren't suitable rather than take the money and deliver something mediocre.
If you put us through this evaluation process, you should. Ask us the hard questions. Call our references. Read our Clutch reviews — including the ones that mention challenges. That's how you'll know whether we're the right fit for your project.
