Comparison Table
CDK Global
enterpriseDealer management system covering parts inventory, service, sales, and accounting for automotive dealerships.
Fortellis API connectivity extends CDK Drive beyond native dealership workflows while preserving the core dealer record.
CDK Drive links parts personnel to repair orders, customer vehicles, technicians, and accounting entries. Shared records reduce duplicate entry between service and parts departments, while configurable permissions support department-level control. Fortellis gives integration teams defined connection points for external applications and dealership workflows.
The tradeoff is implementation complexity because CDK Global covers more departments than a focused parts counter application. A franchised dealer group with several rooftops can apply common operating rules while configuring location-specific vendors, pricing, and stocking requirements.
- +Unifies parts, service, sales, and accounting records
- +Fortellis API ecosystem supports third-party application connections
- +Configurable permissions support department-level operational control
- +Connects counter activity with repair-order workflows
- –Broader dealership scope adds implementation complexity for parts-only businesses
- –Independent aftermarket wholesalers may need specialized catalog functionality
- –API projects require technical integration resources
- –User experience can vary across modules and product lines

How to Choose the Right Auto Parts Computer Software
In auto parts computer software, the real separator is whether your data stays consistent end to end via the data update cadence and data mapping coverage. We look for tools that control automation and API access without forcing manual reshuffling of part numbers and inventory signals.
Update cadence for parts and inventory
Why it matters
Update cadence for parts and inventory determines how often your catalog and availability reflect reality. When the cadence is slow or opaque, counters and searches drift from what your customers see.
How to check
Ask what triggers updates and how quickly changes propagate after a supplier feed or internal adjustment. Then in the demo, change a sample availability value and verify when it appears in catalog search and any availability view.
Mapping coverage for part numbers and supersession
Why it matters
Mapping coverage for part numbers and supersession prevents the same part from showing up under different identifiers. If coverage is weak, staff will misquote or sell the wrong replacement.
How to check
Request a demo scenario with a known supersession chain and a cross-reference case. Check whether the system returns the correct replacement and also preserves the original part for traceability in the result screens.
Automation and API surface for sync
Why it matters
Automation and API surface for sync is what keeps workflows from becoming spreadsheets and emails. Strong automation also reduces re-keying when you move orders, availability, and catalog changes across systems.
How to check
In a sandbox or demo, ask for an API call or scheduled sync that updates a catalog item and then confirm it lands correctly. Review what endpoints exist for orders, inventory, and catalog updates, and verify any authentication and rate limits you are shown.
Search result precision for messy inputs
Why it matters
Search result precision for messy inputs matters because buyers type inconsistently: abbreviations, mixed formats, and partial numbers. Better precision reduces the number of manual picks and corrections.
How to check
Test part search with multiple imperfect inputs (partial number, alternate format, extra characters). Confirm that results rank correctly and that filters refine results without hiding obvious matches.
Admin workflow controls for catalog changes
Why it matters
Admin workflow controls for catalog changes control who can modify what and when. That matters when your team must prevent accidental edits that break quoting or availability.
How to check
Ask how changes move from draft to live and who can approve them. In the demo, attempt a user-role change and verify whether edits are audited and whether rollbacks are possible for a catalog item.
Order traceability to catalog data
Why it matters
Order traceability to catalog data lets you explain what was sold and which identifiers were used at the time. Without it, disputes with customers or suppliers become difficult.
How to check
Create a sample order in the demo and open the order details to trace back to the exact catalog record(s) used. Confirm you can review the identifier, replacement logic applied, and the timestamps tied to that decision.
Red flags
- Unclear update cadence that doesn’t match daily operations
- Replacement and cross-reference results that conflict with known examples
- Catalog edits without approval steps or readable audit history
Fit by situation
- If your team reconciles availability several times per day, prioritize Update cadence for parts and inventory.
- If you sell replacements and need correct alternates under quotes, prioritize Mapping coverage for part numbers and supersession.
- If you sync orders and availability with other systems, prioritize Automation and API surface for sync.
