7 Best DMS Software for Multi-Rooftop Dealer Groups 2027

Pick the category before the vendor

For a multi-rooftop group, the first decision is not which demo looks best. It is whether one dealer management system can share inventory and customer records across rooftops, roll accounting up by store, and let you export your own data without an unexpected fee. A dealer management system (DMS) is the core software that holds a dealership's deals, repair orders, parts records, accounting and customer files, so a weak choice touches every department at every store.

The large incumbents still hold most of the market. One research firm estimates that CDK Global, Cox Automotive's Dealertrack and Reynolds and Reynolds together hold Big-three combined share: approximately 80% according to Emergen Research (2025). The same page uses that figure both for market share and for dealer locations, so read it as directional rather than exact.

TL;DR: Tekion and DealerBuilt state multi-rooftop scope most directly on the pages we opened, and Dealertrack implies it. CDK's Fundamentals suite is aimed at smaller operators, Reynolds' pages state no rooftop scope, DealerSocket's IDMS page is built for independent and buy-here-pay-here dealers, and PBS's DMS page does not describe groups. None of the product or pricing pages we opened publishes a price.

Key Takeaways

• Only Tekion and DealerBuilt state multi-rooftop scope directly on the pages reviewed. Dealertrack implies it, and the other four pages say little or nothing about groups.

• None of the pages reviewed publishes a per-rooftop, per-user or per-module price, so every pricing entry in this guide reads Quote-based.

• Integration figures are vendor claims. Ask each vendor for the live feed list for your own OEMs, not the headline count.

• A pricing consultancy describes a per-rooftop monthly subscription as the primary pricing meter, so ask every vendor to quote the same rooftop-and-module scope.

• Data-export format and fees decide how hard it is to leave. Get them in writing before the final demo.

• The DMS is one layer. Exception routing across rooftops is a separate build with its own owner and review points.

How we evaluated these tools

This guide is built from public material only. We opened each vendor's product pages, checked pricing pages where they exist, and read independent sources for market and pricing-structure context. We did not run any of these products, so the scale below is a buyer's checklist for demos, not a set of test results. The review-site pages we tried (Gartner, G2 and TrustRadius) were not accessible during research, so this guide contains no review-site ratings.

The weights reflect what a group loses most from if it picks wrong. Governance and integration carry the most weight because they are the hardest to change after go-live.

In a demo, score each vendor from 1 to 5 on each row, multiply by the weight, and compare totals. A vendor that scores well on governance but cannot state its export terms should not win on the total.

Feature matrix: what each vendor's own pages say

The matrix records what each vendor's own pages state. "Not stated" means the page we opened was silent. That is a question for the demo, not proof the feature is missing.

Two of the rows show the same pattern. Where a vendor publishes a headline integration number, it is a count of connection points, not evidence that every feed you need is live for your OEMs.

The figures behind this guide

Every number used in this guide appears below with the page it came from. The figures are either market estimates or vendor claims, and the table says which is which.

The market figures are the only ones here that come from independent research. The rest are what vendors say about themselves, so verify them in a demo before you rely on them.

Vendor profiles

Each profile separates what the vendor's page says from what we conclude. The "Implementation" line states what the page does not cover, since no vendor page we opened described a migration timeline.

Tekion ARC

Tekion sells its DMS inside Automotive Retail Cloud (ARC), which also covers CRM, service, payments, payroll and analytics. The page says ARC works for "a single location or manage a multi-rooftop dealer group" and cites "centralized operations, shared vehicle inventory, and unified reporting across every rooftop." Primary source: Tekion ARC page.

Best fit: groups that want one cloud platform across DMS, CRM, service and payments, and that will move rooftops in phases.

Limitations: the page publishes no rooftop count, pricing model or migration timeline. Its customer logos and testimonials are vendor-selected. One results figure on the page carries placeholder attribution, so do not rely on it.

Implementation: the page covers onboarding of new rooftops, brands and users but not a migration schedule. Ask for a rooftop-by-rooftop phasing plan with named owners on both sides.

Evidence: the page describes the platform as built on an ISO 42001-certified platform and names Asbury Automotive and Ken Garff Automotive Group as partners in its FAQ.

DealerBuilt Lightyear

Lightyear is DealerBuilt's cloud DMS, and its page speaks to groups directly. It describes shared inventory and "a single name file across stores and departments," and it says journal entries between stores or franchises can be automated through inter-company transfer features. Primary source: DealerBuilt Lightyear page.

Best fit: groups that put accounting roll-ups and intercompany posting at the center of the decision. The page also lists multi-EIN payroll support.

Limitations: the page gives no rooftop counts, migration detail or add-on costs. Phrases such as "trusted by the industry's top groups" are unverified claims. The "200+" figure refers to integration providers, not dealerships.

Implementation: no timeline or conversion process is described. Onboarding is described only in general terms, so ask for the conversion plan in writing.

Evidence: the integration platform lists providers, according to DealerBuilt (200+ providers).

Dealertrack DMS (Cox Automotive)

Dealertrack DMS is a cloud system sold under Cox Automotive. Its page points to connections with other Cox Automotive products and third-party software, and it includes a data-fee calculator for estimating savings from switching. Primary source: Dealertrack DMS platform page.

Best fit: groups that value open integration and want the option to connect CRM, digital marketing and inventory tools from the same parent company.

Limitations: the page does not say explicitly whether it is built for groups. Its testimonials include a multi-location group, but no group feature list is published. The claim that it avoids "hidden fees" is the vendor's own, and the data-fee calculator is a sales tool.

Implementation: no timeline is published. Ask for an install schedule and the scope of data conversion.

Evidence: Dealertrack OEM integration points: over 375 according to Dealertrack (vendor claim, "with over 375 integration points (and counting)").

CDK Dealership Xperience Platform

CDK's DMS is sold inside its Dealership Xperience Platform, which lists six suites: Foundations, Fundamentals, Modern Retail, Vehicle Inventory, Fixed Operations and Intelligence. Primary source: CDK Dealership Xperience Platform page.

Best fit: franchised groups that want modular suites and a cross-store view. The page includes a testimonial about comparing stores in the Intelligence suite and mentions the Benzel-Busch family of dealerships.

Limitations: the page does not separate single-rooftop and multi-rooftop offerings. The Fundamentals suite is aimed at "one-to-two-site franchise dealers and independent auto dealers," according to CDK (page wording). The modular design means the total depends on which suites and bolt-ons you add. The page itself cites 10–15 additional bolt-ons alongside the DMS, according to CDK (2022 DealerTech report).

Implementation: no migration detail is published. Ask for a suite-by-suite map of what a group would buy.

Evidence: the platform page and the testimonials it carries. Ask for named group references you can call.

Reynolds Retail Management System

Reynolds' 2026 push sits inside its Retail Management System. At NADA 2026 it introduced Rey, an AI agent that runs across the system and draws on Spark AI, a unified data layer. Chris Walsh, the company's president and acting CEO, said "Many AI tools rely on siloed data that is incomplete or inaccurate." Coverage is in FI Magazine's NADA 2026 report, which says Rey is designed for employees across departments.

Best fit: stores that want an established DMS with an AI layer that reaches employees in several departments.

Limitations: the pages we opened state no rooftop scope. The ERA-IGNITE product page loaded only its title during research, so its scope could not be checked. The Reynolds experience page publishes no pricing or licensing model, and its results are testimonial-based.

Implementation: nothing on migration appears in the pages opened. Ask for the conversion scope and the data-quality work Rey depends on, since Walsh's own point is that AI tools need complete and accurate data.

Evidence: the Reynolds experience page and the FI Magazine coverage linked above.

PBS Systems v10 APEX

PBS Systems' flagship is v10 APEX, with modules for accounting, sales, service, parts, CRM and a Digital Service Suite. Its DMS page says PBS has been around "for over 38 years," according to PBS Systems (company history, not an installed base).

Best fit: stores that want an accounting-first, all-in-one DMS from a long-established vendor.

Limitations: the page does not state rooftop support, group features, deployment model (Windows or cloud) or installed base. We could not verify group capacity from it, and the page offers only a "Request a Demo" call to action.

Implementation: nothing published. Ask how group-level data would be set up and how each rooftop would be installed.

Evidence: the DMS page. Request a group reference before relying on it.

DealerSocket IDMS

IDMS is, in its own words, "built for independent and BHPH dealers," and it includes loan-servicing tools. Primary source: DealerSocket DMS page.

Best fit: independent dealers and buy-here-pay-here operators that need loan servicing alongside the DMS.

Limitations: as marketed, this is not a franchised multi-rooftop product. The IDMS page describes no multi-store feature, and "group" appears only in a contact-form job-role dropdown. This is the clearest disqualifier for a franchised group in this list.

Implementation: nothing published. The page directs buyers to "Speak with an expert."

Evidence: DealerSocket integrations: more than 50 according to DealerSocket (vendor claim, "with leading industry software partners").

Who should choose each vendor

Pricing and total cost: what you can check today

Pricing checked October 25, 2026.

None of the product or pricing pages we opened publishes a price for a rooftop, a user or a module. The table shows what each page offers in place of a price, so the Quote-based label below reflects that absence rather than a claim about cost.

A pricing consultancy's August 2026 guide treats a per-rooftop monthly subscription as the primary pricing meter and rejects per-user recurring pricing as a primary model. Its three cost models use a 20-rooftop group, according to Monetizely (2026), but those are modeling inputs, not vendor quotes, so this guide does not reproduce their outputs.

Ask each vendor to quote the same scope: rooftops, named users per rooftop, modules, OEM feeds, third-party integrations, migration and training, and annual increases. The same guide notes that costs have drifted upward through integrations, data-access charges and add-on modules, so ask for the escalator in writing.

Who this is for

This guide is for owners and operations leads at groups that run several rooftops and are close to a DMS decision. It is less useful for a single-store independent, whose shortlist should start from references at stores like its own.

Red flags: the vendor will not put data-export format and fees in writing; no one in the group can name the owner of each rooftop's exception report; the shortlist rests on one feature demo rather than your own store data.

Where exception work falls between the DMS and the store

Most groups' pain is not the DMS screen itself. It is the morning exception list: unposted deals, open repair orders and missing F&I products that someone must chase at every rooftop. Reporting software is a separate decision, covered in our guide to reporting software for car dealerships.

A proposed US Tech Automations design would start with a nightly exception list. The trigger is a scheduled export from the DMS. The action is to group exceptions by store and write them to a shared sheet. The output is a per-store list that a group controller reviews before any store receives it. The prerequisites are a scheduled export or vendor-approved API access, written data-use permission, and a named owner for each rooftop. The public US Tech Automations page names Google Sheets, QuickBooks and HubSpot among its integrations, but it names no DMS connector, so the DMS feed is the first thing to confirm.

A second proposed step would handle reminders. The trigger is an exception still open after a deadline the group sets. The action drafts a reminder to the store's manager, and each draft waits in an approval queue where a person approves, edits or rejects it before it sends. The output is a sent message and a log entry. The public page describes that approval queue, but it does not describe audit logs, so ask for the log format before you rely on one.

Worked example (illustrative, not measured): take a six-rooftop group where each store's operations lead spends 4 hours a month chasing exceptions by hand. A proposed nightly list cuts that to 1.5 hours per store, so each store saves 2.5 hours a month. Across six stores that is 15 hours a month, or 180 hours a year (2.5 × 6 = 15; 15 × 12 = 180). If the reminder goes out as a text, Twilio's Message resource returns an error_code on each failed send and a date_sent value for when it went out, so the log shows which reminders never arrived and a person can re-route them.

Common mistakes

• Comparing integration headline numbers without asking which feeds are live for your own OEMs.

• Accepting a group demo built on a single-store dataset.

• Signing before the data-export terms are in writing.

• Treating every Quote-based line as comparable when each vendor has quoted a different scope.

• Buying the workflow layer before the DMS feed works.

Decision checklist

• Get a price per rooftop, per user and per module from each vendor, in writing, for the same scope.

• Get the live OEM and third-party feed list for your own brands.

• Get the data-export format, frequency and any fee, in writing.

• Get a migration plan with rooftop phasing and a named owner on each side.

• Run a group reporting demo on your own store data, not the vendor's sample.

• Get the exit terms before you sign.

Building it in Zapier, Make or n8n instead

A group can stitch the same flow together in Zapier, Make or n8n. Those tools can keep run histories, retry failed steps, branch on errors and keep audit evidence when they are configured that way. What the buyer then owns is the design: making sure a rerun does not double-send, setting escalation rules, controlling access to the DMS export, and maintaining the flow when the DMS changes its export format. A managed design would configure the same pieces, but the prerequisites are identical: a DMS feed, named owners and a written review step. Choose a stitched build if one internal person can own it for years. Choose a managed design if the group wants that ownership outside the store.

Frequently asked questions

Which DMS should a multi-rooftop group shortlist first?

Start with the two vendors whose own pages state multi-rooftop scope most directly, Tekion and DealerBuilt, and test each on your own store data. Add Dealertrack if open integration is the priority. Drop DealerSocket's IDMS from a franchised shortlist, since its own page describes independent and buy-here-pay-here dealers.

Do any of these vendors publish prices?

No. None of the product or pricing pages we opened publishes a per-rooftop, per-user or per-module price, so every price entry in this guide is Quote-based.

What should a group confirm about data export?

Confirm the export format, how often data can be pulled, and whether any fee applies to the export itself. Get all three in writing before signing, because they set the cost of leaving later.

Is a DMS enough for group reporting?

Often not on its own. The DMS holds the records, but exception routing and store follow-up usually need a separate layer with its own owner and review step.

When is a simpler tool the better choice?

When the DMS's own reports already reach the managers who act on them, a simpler setup usually wins. When NOT to use US Tech Automations: a group whose DMS already sends managers the exception reports they read each morning needs no added layer. A group that wants one vendor to own DMS, CRM and payroll may get more from the built-in modules of a platform such as Tekion or DealerBuilt than from a separate workflow layer. A team that can own a spreadsheet and a monthly export may not need automated routing at all.

Choosing a shortlist

Shortlist two or three platforms, ask each for the same rooftop-and-module scope, and score them on the table above during a demo with your own store data. If exception work is the constraint, see how US Tech Automations configures this for a proposed design, and list the DMS export and review steps you would need to confirm first.
