CONNECT EVERYTHING

Integrations that Connect Your Entire Parts Business

Parts Square plugs into the systems you already use—ERPs, POS, DMS, CRMs, warehouse distributors, catalog providers and more—so your online store, in-store counters, and back office all stay in sync.

Running an automotive business today means juggling a lot of software: an ERP for purchasing and inventory, a POS at the counter, a DMS or shop management system in the bay, a CRM for follow-ups, and a dozen marketing, shipping and accounting tools. Parts Square sits in the middle as your commerce engine, integrating with these systems so data flows automatically and your team can focus on selling parts—not rekeying information.

THE CHALLENGE

Why Integrations Matter So Much in Auto Parts

The automotive world is tougher than generic e-commerce.

You're dealing with:

Complex Fitment & Vehicle Data

ACES, PIES, custom catalogs with millions of applications.

Multiple Warehouse Distributors

Different rules, pricing, and cut-offs for each vendor.

Mixed Inventory Models

Stocked inventory, special orders, and drop-ship all at once.

Multi-Channel Sales

In-store sales, phone quotes, and online orders happening simultaneously.

Integration Complexity

Without Strong Integrations, You End Up With:

Duplicate data entry between systems
Out-of-sync inventory and overselling
Conflicting pricing between website, store, and marketplaces
Reports that never quite match

Parts Square is designed from day one to connect all these moving pieces, keeping your data consistent and your customers confident that what they see is actually available.

CONNECTIVITY

How We Integrate: APIs, Files, Databases and Vendor Feeds

We don't depend on any one "app store" or proprietary plugin marketplace

APIs

REST, SOAP, GraphQL and vendor-specific APIs for real-time connectivity.

Flat Files

CSV, TXT, XML, JSON via SFTP/FTP/HTTPS for scheduled exchanges.

Databases

Direct, read-only access to on-prem or cloud databases where appropriate.

Vendor Feeds

WD inventory, pricing and freight rules from major distributors.

Hybrid Setups

Combinations of the above when a single method isn't enough.

Proven Connectors

For automotive ERPs, catalogs, and WDs, we already have mature integrations.

If your system can export data or accept data, we can almost always integrate it.

Don't See Your System? We Can Still Integrate It.

We regularly integrate with homegrown ERPs, legacy on-prem systems, and niche tools that never make it onto public app marketplaces. As long as we can get to an API, export file, or database, we can usually:

Import your products, inventory, pricing and customers
Export orders, invoices, payouts and shipping data
Keep everything in sync on a schedule that matches your business

If you have an unusual or proprietary setup, we'll review it with you and outline the fastest path to a working integration.

OUR PROCESS

What an Integration Project Looks Like

Every integration is a little different, but most follow a simple pattern

1
Discovery

We review your systems, connection options and business rules.

2
Mapping

We map fields between your systems and Parts Square (products, customers, orders, etc.).

3
Prototype

We set up a test connection in a sandbox environment and verify data flow.

4
Go-Live

We turn on the integration, monitor closely, and adjust any mappings or rules.

Ongoing Support

We keep an eye on feeds, API changes and provider updates so your integration remains stable.

If you're planning a new website, re-platforming, or just trying to clean up a messy tech stack, we can fit Parts Square into your existing systems instead of forcing you to replace everything at once.
