How to Choose a Software Development Company: A 10-Step Checklist
To choose a software development company, define your project goals and constraints, shortlist firms with relevant case studies, evaluate them with a weighted scorecard covering technical expertise, delivery process, communication, security and cost, interview the actual team, check references, compare proposals on scope and assumptions as well as price, and start with a small paid pilot before committing to a large contract.

The Vendor Evaluation Scorecard
Score each vendor 1–5 per criterion, then multiply by the weight. Adjust the weights to your priorities.Example: Vendor A scores 4, 4, 5, 3, 4, 4, 3 and 4, for a weighted total of 3.95 / 5.
| Criterion | Weight | What to look for |
|---|---|---|
| Relevant experience | 20% | Similar projects, industry, scale; live products you can try |
| Technical expertise | 15% | Stack depth, architecture thinking, code quality samples |
| Delivery process | 15% | Agile practices, sprint demos, QA, DevOps, documented process |
| Communication | 15% | Responsiveness, English proficiency, time-zone overlap, clarity |
| Team quality & stability | 10% | Seniority mix, low turnover, named key people |
| Security & compliance | 10% | Secure SDLC, NDA/IP terms, relevant compliance (HIPAA, GDPR, SOC 2) |
| Cost & commercial terms | 10% | Transparent pricing, realistic estimate, fair contract |
| Post-launch support | 5% | Maintenance plans, SLAs, warranty |
| Total | 100% | - |
25 Questions to Ask a Software Development Company
Experience
Which projects have you delivered that are most similar to ours? · Can we see or use a live product you built? · What went wrong on a past project, and how did you handle it?
Team
Who exactly will work on our project, and how senior are they? · Can we interview them? · What's your developer turnover rate? · What happens if a key team member leaves?
Process
What's your development methodology? · How often will we see working software? · How do you estimate, and what assumptions sit behind this estimate? · How do you handle scope changes? · What does your QA process include?
Technical
Why do you recommend this tech stack for us? · How will the architecture scale and stay maintainable? · Do you write automated tests? What coverage do you aim for? · How do you handle CI/CD and deployments?
Security & ownership
Who owns the code and IP? · Where will the code be stored, and who controls access? · How do you protect our data and credentials? · Which compliance standards have you worked with?
Communication & commercial
What hours will overlap with ours, and who's our main contact? · What's included in the price, and what's extra? · What are the payment terms and milestones? · What support do you provide after launch? · How do we exit the relationship if needed?

How to Compare Software Development Proposals
Tip: if one proposal is 50% cheaper, find out what's missing from it.
| Check | Why it matters |
|---|---|
| Scope covered | Are the same features included? Is anything listed as an "assumption" or out of scope? |
| Team composition | Same roles and seniority? Is QA, design or project management missing? |
| Timeline | Realistic for the scope? Does it include discovery, testing and release? |
| Pricing model | Fixed price, time & materials or monthly? What triggers extra cost? |
| Assumptions & dependencies | What do they expect from you (content, access, approvals)? |
| Post-launch | Warranty period, support and maintenance costs |
| Total cost of ownership | Build + hosting + licences + maintenance over 2–3 years |

| Your situation | Best-fit model | Notes |
|---|---|---|
| Defined MVP, no in-house tech team | Project-based (fixed or milestone) | Vendor provides PM, design, QA |
| Ongoing product with your own product owner | Dedicated team | Flexible scope, monthly cost |
| In-house team needs specific skills | Staff augmentation | You manage the work |
| Tight budget, need overlap with US/EU hours | Offshore with partial overlap | Agree 3–4 overlapping hours |
