(FAQ) You might be wondering:

Software‑as‑a‑Service (SaaS) delivers applications over the internet—no downloads, just a login. Because revenue depends on activation, retention, and expansion, UX is crucial. As a SaaS design agency, we focus on onboarding, clarity, and in‑product UX that reduce friction and keep users engaged over the long term. The product is typically accessed via a web browser and hosted on servers owned by the vendor who provides the solution product page. A common example of this type of SaaS software would be Hotjar. Hotjar is accessed through an internet browser page and runs on Hotjar's own servers in their data center. Users are not required to download and install any software to access and use Hotjar software, just like other SaaS products such as Typeform or Salesforce. SaaS websites and products rely heavily on good UX design to retain customers and maintain product profitability. The SaaS market is growing fast, and it is an important part of the future of software. The majority of the applications businesses are using today are SaaS-based. So building a SaaS product now and jumping on product design trends would be the right choice for your business. Our agency can help you get started with your Saas designs and website landing pages.

We’re a SaaS design company with a deep track record across Fintech, Healthtech, Edtech, data security, and more—backed by real case studies like Edgeport, LOX, and TelQ. Our team covers research, UI/UX, and development to ship SaaS products and websites that convert and scale. We call SaaS product design one of our content and design specializations. And we have the experience needed to design and develop SaaS products that will be user-centered and aesthetically pleasing. We also always keep in mind our client's business objectives and goals when designing a product, so we design SaaS products that will be engaging (what is essential in the SaaS field) and ones your users will really enjoy using. You should check our SaaS case studies if you haven't already done so. There, you'll see a selection of the products we've designed over the years for SaaS companies. We design everything from a common Saas product to a product landing page that will add value for your users.

Many factors go into designing a SaaS product. A well-designed user interface (UI) and user experience (UX) can often be the key difference between success and failure for a design product. At Merge, due to our broad experience and expertise in SaaS design best practices, we know what makes a successful SaaS product and how to design SaaS applications to maximize success. Our designers bring together years of experience to ensure a smooth software UX that encourages customers to keep using your product. We'll work with you to create a top-notch SaaS product that will meet all of your and your future customers' needs. An onboarding experience engages users with your product and is an important part of your marketing strategy. Our design management team can also help you create a custom onboarding process that engages your users.

Yes. We offer MVP development and POC design to validate your idea quickly with the smallest set of features that delivers value. Once the MVP proves traction, we iterate into a full product with refined UX, performance, and security.

The answer to this question may sound banal, one you have probably heard many times before, but it is really so - the time frames and the cost of the design projects vary, and they depend on numerous factors, so it can't be answered universally for all SaaS products. SaaS prices and development times vary based on factors such as the complexity of a product's UI, the external resources the app will need, and how many users you anticipate serving with the app or site page. What we can tell you (and what our clients usually tell us) is that we design and develop fast and at a reasonable cost. Just book a call with us, tell us about your business, the SaaS product you want us to design or develop, or both, and we'll give you a free estimate of the time and the cost of the project individually.

For startups, we optimize speed to learning: founder‑led discovery, prototype‑driven validation, and landing pages that convert early demand. For scale‑ups, we prioritize stability and efficiency: design systems, self‑serve onboarding improvements, and data‑informed experiments that lift activation and expansion. In both cases, we staff to your goals—lean “tiger team” for speed or a cross‑functional squad for sustained growth.

The answer is not necessarily. You don’t need to have coding skills to build a SaaS startup or product design. There are many ways you can approach building a SaaS company that does not require any coding skills whatsoever. You might need to be technologically savvy and understand the basics of how the software works for your product. And then you hire someone who knows how to code your SaaS product, that’s it. You just need a great design idea, and our team of developers will build a great SaaS product from it.

SaaS has unique conversion moments—trial, onboarding, pricing, activation, and retention. A saas website design agency understands subscription funnels, product‑led growth, and how messaging ties to in‑product UX. Many SaaS web design agencies also align site architecture with the product roadmap and analytics, so your website drives qualified sign‑ups, not just pageviews.

Bring in specialists when you’re planning a pivot, improving onboarding, launching a new pricing model, or seeing churn/low activation. If you’re choosing between redesign vs. incremental improvements, hire saas ux consultants to run research, benchmark UX, and prioritize the highest‑ROI fixes.

Our SaaS design services typically include discovery and user research, information architecture, UX flows, wireframes, UI design, design systems, interactive prototypes, usability testing, and dev‑ready assets. When we implement, we handle front‑end builds, integrations, and performance/accessibility checks. We also provide ongoing optimization and design support.
