Web Development for B2C SaaS.

Fast websites that turn traffic into pipeline. Designed and shipped for B2C SaaS companies, not generic templates with b2c saas swapped in.

Why this matters

Why B2C SaaS companies need Web Development built around their unit economics.

Most B2C SaaS companies are operating on sites or software stacks built three to five years ago for a different version of the buyer. 7-day trial vs free-tier conversion economics drive the entire growth model, both work but require different funnels. The infrastructure decisions that compound are the ones made with the operator in the room, not the ones made in a vacuum.

Inparlor's Web Development engagement for B2C SaaS companies reflects that. Custom marketing sites built on Next.js and deployed on Vercel or Hetzner. The deliverables below are scoped against the unit economics, annual ltv of $60-$300, trial-to-paid conversion of 30-60%.

Where most agencies treat B2C SaaS companies as another vertical to learn on, we treat the vertical as the starting point. App Store and Play Store policy changes (subscription rules, sign-in-with-Apple, family plans) move the unit economics by 10-20%. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Our B2C SaaS-specific approach

How Web Development runs in B2C SaaS companies, operationally.

  • Redirect map on day one

    Even brand-new sites have legacy URLs to honor, orphaned PDFs, archived blog posts, vendor microsites. Missing a 301 is how organic traffic dies on launch day, so the redirect map is week-one work, not a launch-day checklist.

  • Performance budget held through deploy

    Largest Contentful Paint under 2 seconds on a 4G mobile connection. Cumulative Layout Shift under 0.05. We hit it on every preview deploy, not just at launch, and we keep hitting it for 90 days after.

  • Editorial workflow, not a CMS dump

    We default to Sanity, Contentful, or MDX-on-GitHub depending on team size. Editors get a workflow they will actually use, preview environments, scheduled publishes, and roll-back if anything breaks.

  • Measurement wired before the homepage is approved

    GA4 events tied to revenue, not pageviews. Meta CAPI on day one for any site that will run paid traffic. The dashboard tells the truth before the brand approves the design.
