Whether you’re managing large catalogs, technical product configurations, or integrating with legacy ERP systems, our development team brings deep technical expertise.

We understand that manufacturers often need more than a storefront, they need a platform that mirrors their business logic, including offline workflows. With advanced back end development, B2B ready front ends, and custom developed workflows, we help brands unlock Shopify’s full potential. 

industry specific shopify challenges solved

We understand the nuts and bolts of Auto & Parts merchants

Shopify Strategy
Manage Large Catalogs & Fitment with Ease
Managing large product catalogs on Shopify is a core challenge for most auto and parts merchants, especially when dealing with Year Make Model search, ACES PIES data, and complex product taxonomies. Without proper fitment filtering or a Product Information Management system, merchants risk poor user experience, inaccurate search results, and lost sales. Ambaum specializes in custom Shopify solutions for high SKU auto stores, with support for ACES PIES, VCdb, and scalable Year Make Model search implementations.
App Guidance and Trade Offs Cover
Reduce Returns & Streamline Checkout
Auto and parts stores on Shopify face high return rates, confusing refund workflows, and checkout challenges like managing core charges or warranty returns. These issues directly impact profitability and conversion rate, especially for brands selling fuel injectors, batteries, or other parts that require deposits or VIN verification. Ambaum helps merchants reduce friction with optimized Shopify returns workflows, B2B checkout customizations, and core charge handling logic that is tax compliant and customer friendly.
Operations and Workflows
Connect Legacy Systems to Shopify
Most auto parts businesses rely on legacy systems like ERPs, EDI platforms, or VIN decoders that do not natively connect to Shopify. Ambaum builds custom integrations that bridge the gap between Shopify and your internal, and often legacy systems, syncing orders, inventory, customer data, and part fitment through modern APIs. Whether you are using TrueCommerce, SPS Commerce, or a custom middleware solution, we design robust Shopify integrations that reduce manual entry and improve operational visibility.

In-depth resources to help auto and parts merchants navigate Shopify challenges with confidence.
How do I set up Year Make Model search in Shopify?

Year-Make-Model (YMM) search lets buyers filter parts by vehicle attributes to quickly find the right fit. Ambaum implements custom YMM functions in Shopify using ACES/PIES data, ensuring customers only see compatible products for their car or truck. This reduces friction, boosts conversion, and makes your catalog easier to navigate.

How do I set clear returns and exchange policies for my auto parts Shopify store?

Clear returns, exchanges, and core charge policies build customer trust and reduce costly disputes. Ambaum helps auto retailers configure Shopify PDPs to highlight timelines, restocking fees, and shipping rules, while also building intelligent RMA, warranty, and exchange forms that connect directly to your CRM or ERP.‍

How do I use a VIN decoder in my auto parts Shopify store?

A VIN decoder translates a vehicle’s 17-character ID into factory details like year, make, model, and engine specs. Ambaum integrates VIN lookup tools with Shopify so customers enter their VIN and instantly see only the parts that fit, reducing errors, returns, and abandoned carts.

Ambaum customizes Shopify PDPs with manuals, install guides, core charge handling, inventory visibility, compliance warnings, cross-sells, and condition grading, ensuring shoppers buy with confidence.

How can auto parts companies use Shopify Plus B2B features to streamline wholesale sales?

Yes. Shopify Plus B2B features let auto parts merchants build catalogs with custom price lists, bulk discounts, and role-based access.

How do data interchanges connect my automotive systems to Shopify?

Auto retailers often rely on legacy databases, EDI feeds, or APIs to manage fitment and inventory. Ambaum builds custom data interchanges and Shopify apps that normalize, sync, and enrich this data, powering VIN lookups, catalog accuracy, and seamless operations across systems.

How do ACES and PIES data help my auto parts Shopify store?

ACES ensures accurate vehicle fitment, while PIES standardizes product details like descriptions and specs. Ambaum integrates these data standards into Shopify, validating fitment, enriching product content, and powering year/make/model searches that increase conversions and customer confidence.‍

How do I handle core charges in my auto parts Shopify store?

Core charges are refundable deposits (like $25 on a $235 returned injector) that encourage returns for remanufacturing. Ambaum configures core charges in Shopify as separate line items, ensuring tax compliance, smooth refunds, and transparent communication during checkout.
