Web Application Development for Auto Dealers.

Web apps and complex sites that do real work, not just look good. Designed and shipped for auto dealers, not generic templates with auto dealers swapped in.

Why this matters

Why auto dealers need Web Apps built around their unit economics.

Most auto dealers are operating on sites or software stacks built three to five years ago for a different version of the buyer. Inventory feeds from the DMS to the website and third-party listing sites break or lag, so VDPs show wrong prices and sold units. 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 Application Development engagement for auto dealers reflects that. We build web applications: customer-facing apps, internal dashboards, data-heavy portals, and complex content sites that go well past a brochure. The deliverables below are scoped against the unit economics, your AOV and retention.

Where most agencies treat auto dealers as another vertical to learn on, we treat the vertical as the starting point. The DMS, CRM, and website are separate systems that don't share data, so staff re-key leads and inventory by hand. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Our Auto Dealers-specific approach

How Web Apps runs in auto dealers, 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.
