Choosing a software development partner is one of the most consequential decisions a growing business makes. The right team becomes an extension of your company; the wrong one costs you months, money and momentum. Portfolios and price lists only tell part of the story. This checklist gives you a practical way to compare companies on the things that actually predict a good outcome — and to spot the warning signs early.

Start with your own clarity
Before you speak to any company, spend an hour writing down the basics: the problem you are solving, who will use the software, the three to five features that matter most, any systems it must connect to, and your timeline and budget range. Teams respond to clarity with better questions and better estimates — and a company that cannot engage with your brief deserves a second look. If you are unsure whether to build at all, our guide to custom software vs. off-the-shelf will help you decide first.
The 10-point checklist
- 1
1. Relevant experience
Have they built something similar, at similar scale?
- 2
2. Process
Discovery, design, build, test, launch — is it clear?
- 3
3. Communication
Who do you talk to, how often, and in what channels?
- 4
4. Team
Who actually does the work, and how senior are they?
- 5
5. Technology fit
Do they choose tools for your needs, or just their favourites?
- 1
6. Pricing model
Fixed, time-and-materials or phased — and what is excluded?
- 2
7. Quality & testing
How do they test, review code and handle bugs?
- 3
8. Security & data
How do they protect data and manage access?
- 4
9. Ownership & handover
Do you own the code, designs and data? Is it documented?
- 5
10. Support after launch
Who maintains it, and on what terms?
1. Relevant experience
Ask for specific examples of projects like yours — in industry, in type (mobile, web, integration, AI) and in complexity. A portfolio shows what they have made; a conversation shows how they think. Ask what went wrong on a past project and what they changed afterwards. Honest answers are a good sign.
2. A clear process
Good teams can explain how a project runs: discovery to confirm goals, design you can react to early, development in small increments with regular demos, then testing and launch. Be cautious of anyone who goes straight from a brief to a price with no discovery.
3. Communication
Poor communication causes more failed projects than weak coding. Agree up front who your day-to-day contact is, how often you will meet, how progress is shown (working demos beat status reports) and how quickly questions are answered. Time zones and language matter less than reliability and clarity.
4. The team you actually get
Ask who will do the work, not who attends the sales call. Find out the seniority mix, whether people are employees or subcontractors, and what happens if a key person leaves. A small, stable, senior-led team is often better than a large, rotating one.
5. Technology fit
A trustworthy partner recommends technology based on your requirements and explains the trade-offs — for example, React Native vs. Flutter vs. native for mobile — rather than pushing whatever they happen to sell. Ask what they have shipped to production, and how they plan for maintenance.
6. Pricing model
Fixed price
- Predictable budget for a well-defined scope
- Works best when requirements are clear and stable
- Changes usually mean change requests
- Check what is excluded — a low fixed price can hide gaps
Time and materials / phased
- Flexible when scope will evolve
- You pay for work actually done
- Needs good reporting and a shared priority list
- Often combined with capped phases or milestones
Whatever the model, ask for the estimate broken down by phase, with assumptions and exclusions written down. Our mobile app cost guide shows what a sensible breakdown looks like.
7. Quality and testing
Ask how they test (automated and manual), how they review code, how they handle bugs found after launch, and what “done” means for a feature. A mature team can describe its quality process without hesitation.
8. Security and data handling
Ask how they manage access to your systems and data, how credentials are stored, how they approach privacy and compliance, and what they do if something goes wrong. For projects that connect systems, include API integration reliability and security in the discussion.
9. Ownership and handover
Get in writing that you own the source code, designs and data, and that you will receive documentation and access to repositories and hosting accounts. You should never be locked in to a single provider by something as basic as not holding your own code.
10. Support after launch
Software needs ongoing care: updates, fixes, security patches and improvements. Ask what is included, what a support agreement costs, how quickly issues are handled, and whether the people who built it will maintain it.
Onshore, nearshore or offshore: what changes?
Where a team is based affects cost, time-zone overlap and communication style, but it rarely determines quality on its own. A strong offshore team with excellent process often beats a weak local one — and the reverse is just as true. What matters is how well the team communicates and how mature its delivery process is.
| Model | Typical advantages | Things to manage |
|---|---|---|
| Onshore (same country) | Easy time-zone overlap, shared business culture, simpler legal arrangements | Usually the highest rates |
| Nearshore (nearby time zones) | Good overlap with lower rates; relatively easy collaboration | Some cultural and legal differences |
| Offshore (distant time zones) | Often the most cost-effective; access to a large talent pool | Limited overlap hours; needs strong communication discipline and clear documentation |
General patterns. Individual companies vary widely.
How to compare proposals side by side
Once two or three companies send proposals, resist the urge to compare only the total price. Lay the proposals next to each other and score them on the same criteria. A simple weighted score keeps the decision grounded in what matters to your project.
| Criterion | What to look for | Suggested weight |
|---|---|---|
| Understanding of your problem | Does the proposal reflect your goals, not a generic template? | High |
| Relevant experience | Similar projects, references and honest lessons learned | High |
| Clarity of scope | Deliverables, assumptions and exclusions written down | High |
| Team and communication | Named people, cadence, demos and escalation path | Medium |
| Price and value | Breakdown by phase; what is and is not included | Medium |
| Ownership and support | Code ownership, handover, post-launch support terms | Medium |
- A summary of your goals in your own words
- Scope broken into phases with deliverables
- Assumptions, dependencies and exclusions
- Timeline with milestones and review points
- The team, roles and time commitments
- Clear pricing and a process for handling changes
- Ownership, confidentiality and support terms
- A realistic list of risks and how they will be managed
Red flags to watch for
Good signs
- Asks detailed questions before quoting
- Explains trade-offs and recommends leaving things out
- Shows relevant work and offers references
- Written assumptions, exclusions and ownership terms
- Regular demos and a named point of contact
Warning signs
- A firm price after a five-minute conversation
- Promises that sound too good: “everything, fast and cheap”
- Vague answers about who does the work
- No testing or documentation plan
- Reluctance to put ownership or exit terms in writing
Questions to ask on the first call
- Which projects have you delivered that are most like ours?
- Who will work on our project, and what is their experience?
- How do you run discovery and what do we receive from it?
- How often will we see working software?
- What is in and out of this estimate?
- How are changes in scope handled?
- Who owns the code, designs and data?
- How do you test and secure what you build?
- What does support look like after launch?
- Can we speak to a past client?
Run a small paid trial
If you are still torn, reduce the risk with a small paid first phase: a discovery workshop, a prototype or a single module. You learn how the team communicates, estimates and delivers — at a fraction of the cost of a full project — and you keep what they produce either way.

Frequently asked questions
Look for relevant shipped work, a clear process with discovery and regular demos, transparent communication, a stable and experienced team, a fair and clearly scoped pricing model, solid testing and security practices, written ownership terms and post-launch support.
