How to Choose a Software Development Company: 15 Questions and 8 Red Flags (2026 Guide)

In brief: Choosing a software company is not about comparing price lists; it is about choosing a team that will walk toward the same goal as you. The lowest quote often turns out to be the most expensive one once the scope becomes clear. To spot a reliable partner, look at whether they put the scope in writing, whether source code and account ownership belong to you, whether they can show live references, whether they have a maintenance and support plan after launch, and, most importantly, whether they answer your questions clearly. Take the 15 questions in this article to your proposal meetings; the answers will usually be enough to decide.

Why does this decision matter so much?

A software project is like the foundation of a building: it can be changed later, but it is expensive. The wrong vendor affects not only your budget but also your time, your competitive edge and your team's morale. Problems rarely start during coding; they start much earlier:

• The scope is not written down, and “we thought that was included” arguments follow.
• Communication depends on one person, and the project stalls when that person leaves.
• Source code, the domain name or server accounts belong to the vendor, so you are held hostage if you want to leave.
• Testing and security are postponed with “we'll look at it later.”
• After launch, nobody takes responsibility.

The good news: almost all of these risks become visible during the proposal stage if you ask the right questions.

Prepare on your side before asking questions

A vendor can only understand your need as well as you can explain it. Before the meeting, put these four things on paper (one page is enough):

1. Goal: What problem will this software solve? (A measurable sentence such as “We track orders in Excel and lose 10 hours a week.”)
2. Users: Who will use it? Customers, employees, dealers? How many?
3. Must-haves: The 5–8 features that must be in the first version. Everything else goes on a “later” list.
4. Budget and timeline range: You do not need an exact figure; a range and a “live by this date” goal are enough.

If you struggle to structure the need, our free Software Scope Planner and SaaS Idea Review tools offer a starting point for turning an idea into a feature list and a first outline.

15 questions to ask the vendor

The questions are grouped under five headings. Next to each you will find a note on what a good answer looks like.

A) Scope and way of working

1. How do you split the project into phases? A good answer: clear phases such as discovery/analysis → design → development → testing → launch → maintenance, with the output of each phase and your approval points. “We'll handle it, don't worry” is not enough.

2. How do you document the scope in writing? A good answer: a document with a feature list, screen flows or a prototype, and an explicit “out of scope” list. Writing down what is out of scope prevents half of the disputes that would otherwise come later.

3. What happens if the scope changes? A good answer: a process in which change requests are received in writing, their impact (time and cost) is stated up front, and work continues with your approval. Requirements change in software projects; the problem is not change but uncontrolled change.

B) Technology and ownership

4. Which technologies do you use, and why? A good answer: not a list of technology names but a justification for your needs: “We chose X for this project because of Y.” Widely used technologies that are easy to maintain and easy to hire for protect your future. A vendor that ties you to a closed stack that only they know is a risk.

5. Who will own the source code? A good answer: one written into the contract, stating that once payment is complete, the source code, design files and documents are delivered to you. Read restrictive wording such as “we grant a licence” carefully.

6. In whose name will the domain, servers and third-party accounts be opened? A good answer: all in your name. The vendor is added as an administrator, and you can remove access if you leave. Accounts opened in the vendor's name make a later move difficult.

7. Do you use ready-made components and open source? How do you manage licences? A good answer: yes, we do, and we check licences. Using trusted open source is normal and lowers cost; what matters is that the licences allow your commercial use.

C) Team and communication

8. Who will work on the project, and who is my contact? A good answer: a team with clear roles (project manager, developer, designer) and a single primary contact. Ask whether the people you meet in the sales meeting will also be on the project.

9. How often will I get updates? A good answer: weekly or biweekly demos or progress meetings, and the chance to see a working build. Stay away from vendors who say “we're working on it” for months without showing anything.

10. Through which channel and during which hours can I reach you? A good answer: a clear written channel, a response-time commitment and a way to reach someone in an emergency. The answer is also a preview of the quality of support after delivery.

D) Quality and security

11. How do you test? A good answer: automated tests during development, manual acceptance testing before launch, and trials on different devices and browsers. “We write the code carefully” is not enough if it does not describe a concrete process.

12. How do you handle security and data protection? A good answer: authentication and authorization design, password protection, data backups, and checks against well-known lists such as the OWASP Top 10. If personal data is processed, ask what they do to comply with KVKK (Turkey's personal data protection law) obligations.

13. What is your plan for performance and scaling? A good answer: a capacity assumption based on your expected number of users, speed targets, and a short description of how the system will scale as you grow. Recommending expensive architectures like microservices without need is as much of a warning sign as not having thought about it at all.

E) After delivery

14. How do maintenance and support work after launch? A good answer: fix times, update policy, backups, monitoring and a support channel are all in a written plan. See our software maintenance and support guide for details.

15. What happens if I want to leave? A good answer: documented code, delivered accounts and help with the handover. Do not hesitate to ask this question; good vendors take it as a sign of trust.

8 red flags

Any one of these may not be a reason to eliminate a vendor on its own, but when two or three come together, stop and think:

1. Quoting a price without asking questions. A fixed price given without listening to you or understanding the need means either the scope will grow later or a ready-made template will be sold to you.
2. A very low price. If the price is far below competitors, consider scope gaps, an inexperienced team or “extra fees” added later.
3. No references or live examples. “We can't show them because of NDAs” is sometimes true, but if no live project or demo can be shown at all, be careful.
4. Evasive answers about source code and account ownership.
5. Saying yes to everything. A good team will sometimes say “that feature is unnecessary for the first version” or “that will lengthen the timeline.” A team that never objects may not be telling you about the risks.
6. A project that depends on one person. If progress stops when one person leaves or falls ill, there is a continuity risk.
7. No written contract or payment plan. A demand for full payment up front, or payments not tied to milestones, costs you your negotiating power.
8. Reluctance to talk about post-launch. A vendor that dodges the maintenance and support question may also be unreachable after delivery.

A table for comparing quotes fairly

Comparing quotes only by total price is misleading. Fill in this table:

To judge a quote amount more accurately, you also need to understand pricing models: our software project pricing models guide compares the pros and cons of fixed-price, time-and-materials and monthly dedicated-team models.

How should you check references?

• Use the live project. Look not at screenshots but at a real, working product: does it open quickly, does it work on mobile, does it throw errors?
• Ask for a project of similar size. A vendor that built a small corporate site may struggle with a multi-user SaaS, and vice versa.
• If possible, talk to a former client. Three questions to ask: Were the schedule and budget respected? How did they behave when problems arose? Would you work with them again?
• Ask about the period after delivery. Finding out whether they still work with that team a year later is a good signal.

What the contract must include

Have your lawyer review the legal text, but check that these headings are present:

• Scope, deliverables and acceptance criteria
• Timeline, phases and consequences of delay
• Payment plan (tied to milestones)
• Transfer of source code and intellectual property
• Confidentiality (NDA) and protection of personal data
• Warranty period and responsibility for fixing defects
• Maintenance and support terms
• Termination and handover terms

Frequently Asked Questions

How many vendors should I request quotes from?

Three vendors are enough for most projects. More makes comparison harder; fewer prevents you from seeing differences in price and approach. Giving every vendor the same brief keeps the quotes comparable.

Is a local company or a remote vendor better?

Location alone is not decisive. What matters is regular communication, a time zone that suits working together, and a strong written process. If face-to-face meetings matter to you, say so from the start.

Should I choose a freelancer or an agency?

A freelancer can suit small, clearly scoped jobs; but when continuity, a backup team and several specialties (design, development, testing, security) are needed together, a team structure is safer. Whichever you choose, ownership and handover clauses matter equally.

Why do quotes differ so much from vendor to vendor?

Because vendors may have assumed different scopes, planned different levels of quality and testing, or included maintenance and support items differently. Realigning the quotes to the same scope, or asking vendors to write down their scope assumptions, shows where the difference comes from.

Does it make sense to start with a small pilot project?

In most cases, yes. A discovery exercise or a small first version lets you test how well you work with the vendor at low risk. That is exactly why we recommend the MVP approach.

Can I change vendors after delivery?

Yes, if the source code, account ownership and documentation are with you. That is why questions 5 and 6 are the most critical items on the whole list.

Conclusion

The right software partner is not the cheapest or the flashiest, but the one that clarifies the scope, tells you the risks openly, leaves ownership with you and stays by your side after delivery. The first thing you can do today: write a one-page summary of your need and ask the 15 questions in this article to three vendors in the same way. The answers will often show you on their own who you want to work with.
