How to start and run a SaaS web design agency: the pages SaaS clients need, how to scope and price the work, the team and tools, and how to add recurring revenue with a white label builder.

Start for free. No credit card required.

A SaaS web design agency designs, builds and keeps improving marketing websites for software companies, with one goal: more trials and demo requests. As of September 2026, the agencies that do well pick the niche deliberately, sell a project plus a monthly retainer, and hand clients a site their marketing team can edit alone.

Book a demo of the white-label builder: your agency's own AI website builder under your brand. Pricing is tailored to your volume and setup, so you get your exact price on the call. How white-label pricing works.

This guide covers what SaaS clients buy, how to scope and price the work, how to staff it, and how to add a second, recurring revenue line.

Why SaaS is a good niche for a web design agency

Sites change constantly. New features, pricing changes, launches and campaigns all need pages. That makes retainers natural.
Results are measurable. Sign-ups and demo requests are tracked, so good work is easy to prove.
Clients understand software. They are used to paying monthly for tools and services.
Referrals travel. Founders and marketers move between companies and talk to each other.

The trade-off: SaaS clients are demanding, move fast and expect you to understand their funnel. You need a process, not just a portfolio.

The pages every SaaS website needs

Page	Purpose	What to get right
Homepage	Explain what the product does and for whom in seconds	One clear headline, product visual, a single primary call to action
Feature or product pages	Show how each feature solves a problem	Screenshots or short videos, outcomes over specs
Pricing	Help visitors pick a plan	Clear tiers, what is included, FAQs, annual vs monthly
Solutions or use cases	Speak to one audience or industry	Their language, their problems, their proof
Comparison pages	Win visitors weighing a competitor	Honest tables, clear differences
Customer stories	Provide proof	Named customers and specific results the client can verify
Sign-up and demo	Convert	Few fields, fast load, clear next step
Docs or help hub	Support users and search	Easy for the product team to maintain
Landing pages	Match paid and email campaigns	Fast, focused, easy to duplicate

A strong landing page practice alone can carry a SaaS retainer.

Scoping a SaaS website project

Start every engagement with a short discovery phase, paid or bundled:

Goals and metrics. Trials, demos, or self-serve upgrades? What converts today?
Audiences. Who buys, who uses, who signs off?
Positioning. What does the product do better than the alternatives?
Content audit. Which pages exist, which rank, which convert?
Technical needs. CMS, integrations with the product's sign-up, analytics, localisation.
Ownership after launch. Who will edit the site, and how technical are they?

The last question decides your platform choice. A site that only a developer can edit turns every small change into a ticket and a frustrated client.

Pricing: project plus retainer

Most SaaS web design agencies combine two lines:

A project fee for a new site or redesign, priced on pages, complexity and the discovery work.
A monthly retainer for landing pages, experiments, new feature pages and fixes.

Quote the retainer in the first proposal. SaaS clients will need changes every month, and a retainer turns that need into predictable revenue for you. Keep pricing tied to deliverables (for example, a set number of new pages and tests a month), not hours.

Team and process

A small SaaS web design agency usually needs four skills, which one person may cover several of:

Strategy and copy. Positioning, messaging and page structure.
Design. Layout, product visuals and a component system the client can reuse.
Build. On the platform the client will run.
Growth. Analytics, testing and reporting.

A repeatable process matters more than headcount: discovery, wireframes, copy, design, build, QA, launch, then monthly optimisation. Write it down and show it in your proposals. It answers the question every SaaS buyer asks: how to choose a web design agency comes down to process as much as portfolio.

Choosing the platform for each client

The platform decision shapes your retainer. Match it to who will edit the site:

Client situation	Platform fit	Why
Marketing team edits weekly, no developers	A visual builder or CMS they can use	Changes do not queue behind engineering
Heavy docs and product content	A headless CMS with developer support	Content flows from the product team
Early-stage startup, small budget	An AI website builder	A credible site in days, easy to change
Many campaign landing pages	A builder with reusable templates	Fast duplication for each campaign

Whatever you choose, document it in a short handover guide. Clients who can make their own small changes renew retainers for strategy work instead of cancelling over slow edits.

Winning your first SaaS clients

Rebuild one page for free as a sample. Pick a SaaS company you admire, redesign their pricing page and write up why. Share it.
Publish teardowns. Short breakdowns of what makes a SaaS homepage or pricing page work attract the exact audience you want.
Partner with adjacent specialists. SaaS copywriters, product marketers and growth consultants often need a design partner.
Answer RFPs well. Larger software companies buy through formal requests. Our website design RFP guide shows how to answer one.

Adding a second revenue line with a white label builder

Many SaaS web design agencies meet the same pattern: a steady stream of smaller businesses asks for help, but a full custom project is too expensive for them. Turning them away wastes the leads. Taking them on at full price loses them.

A white label website builder solves this. You give smaller clients a login to a builder under your agency's brand. They describe their business, the AI builds the site, and you sell a monthly plan for hosting, edits and support. Your team stays focused on the SaaS retainers.

We.Inc is built for this: an AI website builder that runs under your agency's brand, on your own domain. Clients pay you through your own Stripe with a 0% transaction fee. Pricing is tailored to your volume and setup. Book a 30-minute demo and you get your exact price on the call: Book a demo.

A simple 90-day plan

Days 1 to 30: pick the niche, write your process, rebuild one sample page, and set up your own site with SaaS case studies.
Days 31 to 60: publish two teardowns, contact 30 SaaS companies whose sites need work, and launch a white label builder for smaller leads.
Days 61 to 90: close your first project plus retainer, collect results, and turn them into a case study.

Consistency beats a big launch. One well-documented SaaS client win will do more for your agency than a portfolio of unrelated work.

Book a demo. Your brand, your domain, and a 0% transaction fee. Pricing is tailored to your volume and setup, so you get your exact price on the call. See how white-label pricing works or read the white label overview.

Frequently asked questions

What does a SaaS web design agency do?

It designs and builds marketing websites for software companies: the homepage, product and feature pages, pricing, sign-up flows, documentation hubs, comparison pages and landing pages for campaigns. The job is to turn visitors into trial sign-ups or demo requests, and to make the site easy for the marketing team to change.

How is SaaS website design different from other web design?

SaaS sites sell something abstract, change often, and are judged on sign-ups rather than looks. They need clear pricing pages, product screenshots or demos, fast pages for paid traffic, and a CMS or builder the client's marketers can edit without a developer. Launches and pricing changes mean the work never really ends.

How should a SaaS web design agency price its work?

Most combine a project fee for a redesign or new site with a monthly retainer for landing pages, experiments and updates. Price on scope and outcomes, and quote the retainer from the start, because SaaS clients need ongoing changes. Avoid pure hourly billing; it punishes you for getting faster.

Do I need to specialise in SaaS to win SaaS clients?

It helps a lot. SaaS founders and marketing leads want an agency that already understands trials, pricing pages, onboarding and product-led growth. A portfolio of two or three software sites and a clear process for launches will win more work than a general portfolio.

What tools do SaaS web design agencies use?

Typically a design tool such as Figma, a site platform the client can edit (Webflow, a headless CMS, or an AI website builder), analytics, a heatmap or session tool, and an A/B testing setup. The best choice is the one the client's team can run after handover.

Can a SaaS web design agency add a white label website builder?

Yes. Many agencies keep custom work for their SaaS clients and use a white label builder for smaller clients or quick landing pages. On We.Inc, the builder runs under your brand on your own domain with a 0% transaction fee, and pricing is tailored to your volume; book a demo at https://calendly.com/hey-we/30min for your exact price.
