6 Discovery Questions to Ask Web Development Agencies to Find the One for You

Shortlist at least 3 web development outsourcing companies from the above list and book discovery calls with them. During the discovery call, ask these 6 questions to figure out if an agency is the right match for you.

1. What's your experience working with brands like ours? What kind of results did you help them achieve?

Asking these questions helps you gauge their expertise in handling your specific requirements. Agencies with prior experience working for brands from the same industry are well aware of your industry's trends and best practices.

However, ensure the solutions they offer are unique and not cookie-cutter ones. One way to do this is to ask them to share at least 3 examples.

2. What does your tech stack look like?

A web development agency's tech stack is a mirror of the kind of websites they build. An updated tech signals their ability to build scalable, futureproof designs in competitive timelines.

3. Who will be the main point of contact for this project?

Dedicated project managers are a must-have for web development projects to avoid unwanted back-and-forths and reduce completion time. While having direct access to the designers may feel like a perk, it can sometimes become an extra bottleneck especially when they lack the full picture. A project manager ensures smoother coordination, faster decisions, and better use of everyone's time.

4. Are you competent enough to handle scope expansion or tighter deadlines?

The agency you choose should be agile enough to handle scope expansion like additional webpages, marketing collaterals or features (in case of apps) or tighter deadlines without compromising quality. However, consider it a red flag if they are okay with unrealistic demands like cutting turnaround time to a third.

5. Who owns the assets after the website handoff?

​​Ideally, you should be the sole owner of all assets after the website handoff to ensure you can scale without being dependent on a particular agency in the future. At ThunderClap, we provide clients full ownership and intellectual property rights after the handoff.

6. How do you charge for tweaks and iterations after launch?

This gives you an idea of their post-launch support and maintenance plans. Agencies like ThunderClap offer a 30-day free post-launch support to ensure the websites deliver the desired results.

Final Thoughts

Now that you are armed with the right questions, what are you waiting for? Start booking discovery calls with the best web development agencies from the lot. And if ThunderClap is one of them, book a discovery call right away! Our discovery calls are super detailed and we walk you through all these questions and much more even before you ask.

FAQs

1. How much does it cost to pay someone to build a website?

There's no one-size-fits-all pricing for web development. The pricing depends on a lot of factors, like the extra services you need, the website builder tool you use, and the number of web pages involved. However, if you are looking to build a no-code website on WebFlow, it usually starts from $5000.

2. Can you outsource web development?

Yes, you can outsource web development to web development agencies. These agencies let you hire a team of developers to work for you or handle the project end-to-end. Outsourcing helps teams cut hiring costs and bank on the expertise and skillset of web developers with experience working for brands like yours.

3. How to find the best web development agency for your brand?

To find the best web development agency that best suits your needs, follow these steps:

1. Go to Clutch or DesignRush to find the best-ranking web development agencies in your desired location.

2. Compare them against parameters like core services, portfolio, reviews, industries they cater to and standout gestures.

3. Shortlist the best ones and book discovery calls. During the discovery call, ask them detailed questions about their expertise, working style, development philosophy, handoff and maintenance policies.
