How to choose a web development agency: 7 criteria
Most companies make the same mistakes when they hire a developer. Here’s what to look at first so you don’t lose money and time.
Why choosing an agency is a risk
According to research, about 60% of website development projects end up over budget or past their deadline. Often the reason isn’t technical complexity but the fact that the client and the agency were never aligned on expectations, processes and ways of working. Here are 7 criteria that will help you choose well.
1. A portfolio in your niche
General development experience is good; experience in your industry is much better. An agency that has already built projects for real estate developers understands the specifics: CRM integrations, property catalogs, mortgage calculators, dynamic stacking plans. That saves time during the briefing and lowers the risk of mistakes in the requirements.
- Ask to see 2–3 case studies close to your project
- Ask what challenges came up and how they were solved
- Check that the sites in those case studies are actually live
2. A transparent process
A good agency explains from the first meeting how the work will go: stages, timelines, approval points, who your contact person will be. If the answer to “How do you work?” is vague, that’s a warning sign.
- There should be a written specification before work begins
- Regular status updates (at least once a week)
- Access to tasks in a project tracker (Jira, Notion, Linear)
- Sign-off stage by stage, not one final handover
3. The tech stack and how current it is
Ask what the site will be built on and why. The right answer explains why that choice fits your project specifically, not “that’s how we always do it.” A few markers:
- An outdated stack (an old, uncustomized WordPress, jQuery-heavy builds) means a risk of performance and security problems
- Modern frameworks (Next.js, Nuxt) are a strong fit for SEO-driven websites
- Find out who will own the code and the hosting: all of it should belong to you
4. Reviews and references
Don’t rely on the testimonials on the agency’s own website; they’re easy to fake. Ask for contacts of 2–3 clients you can talk to directly. A decent agency will share them without hesitation. If they refuse, ask yourself why.
5. A clear estimate, not a vague range
The estimate should be detailed: specific work items, specific prices. Phrasing like “starting at such-and-such, depending on scope” with no definition of what the scope includes is a red flag. Ask:
- What will cost extra if changes are needed after sign-off?
- Is post-launch support included, and for how long?
- How is work outside the original specification billed?
6. How fast they communicate
Notice how quickly and thoroughly they reply while you’re still negotiating. It’s a direct preview of what communication will look like during the project. If you have to wait days for an answer before the contract is signed, it will only get worse after.
7. Guarantees in the contract
The contract should spell out specific deadlines, acceptance criteria, liability for missed deadlines, and how money is refunded if the work isn’t finished. An agency that’s confident in its work won’t be afraid of these clauses.
The bottom line
Choosing an agency is an investment, not an expense. Spend the time to choose well at the start, and it will save you far more time and money along the way. If you’d like to discuss your project, we’re ready to look at the task and tell you honestly whether we can help.
