Frequently asked questions
DealerBuilt scores D+ on Supergood's API Report Card. DealerBuilt publishes a full SOAP reference, WSDL, FAQ and changelog for its Lightyear DMS API covering sales, service, customers and accounting. Credentials and integration IDs come only through its Certified Partner Network after a contact form and signed agreement.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
DealerBuilt (legal entity LightYear Dealer Technologies, LLC) is an enterprise dealer management system vendor based in Mason City, Iowa with a second office in Grapevine, Texas.
Automotive, franchised new car dealerships and multi rooftop dealer groups in the United States. Early adopters cited publicly include the Galpin Group and the Ken Grody Group. Dealer groups run accounting, deals, F&I, inventory, service repair orders, parts and payroll in Lightyear, with Oplogic for CRM and desking and Vistadash for marketing analytics.
DealerBuilt reported roughly 450 dealer customers when it sold to ParkerGale in 2019 and now claims 200+ certified partners; it is a respected but small share enterprise DMS next to CDK, Reynolds, Dealertrack and Tekion.
Complete dealership system of record: consumer PII including Social Security numbers, driver's license numbers, birth dates and credit application data; deal and lease financial terms; vehicle inventory and VINs; repair orders, parts and payments; general ledger, checks, receipts and payroll with employee bank details.
Software originated inside a dealership before 2008; the public API is a WCF SOAP service labelled version 0.99a whose URL namespace dates to 2016, with a public changelog running from 2017 to May 2022 and a reference page last updated February 2024.
Users say they are limited to existing reports and that learning SAP Crystal Reports to build others is complex. Reviewers report the software changes continually with updates that arrive without notice, occasional bugs, slow loads and crashes mid receipt. Full sourced list under Sources below.
Common alternatives include CDK, Reynolds, Dealertrack, Tekion, PBS Systems. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. There is no official DealerBuilt MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. DealerBuilt doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
