Industrial B2B customers have different needs based on what they buy from you. A customer purchasing raw materials operates differently than one buying finished assemblies. Their ordering patterns, price sensitivity, and cross-sell potential vary significantly.

Segmenting your manufacturing customers by product category creates opportunities for targeted campaigns that resonate with each buyer type. This guide explores how to build and use these segments in Shopify to increase cross-sell opportunities and improve marketing relevance.

Why Product Category Segmentation Matters for Manufacturers

Traditional customer segmentation (by industry, company size, or geography) misses a critical dimension: what the customer actually buys determines how they interact with your business.

Raw materials buyers:

  • Order frequently in large quantities
  • Highly price-sensitive
  • Need consistent supply and lead time reliability
  • May respond to volume discount offers or contract pricing

Components buyers:

  • Order based on production schedules
  • Care about specifications and compatibility
  • Need technical documentation
  • May respond to kitting offers or related component suggestions

Finished goods buyers:

  • May order less frequently but at higher values
  • Care about availability and delivery speed
  • Need less technical support, more fulfillment reliability
  • May respond to new product announcements or accessory suggestions

Understanding which category drives each customer's purchases lets you tailor communications, offers, and the buying experience itself.

Building Product Category Segments in Shopify

The practical approach in Shopify is to (1) automatically tag customers based on what they purchase, then (2) build dynamic customer segments using those tags.

Step 1: Auto-Tag Customers with Shopify Flow

Use Shopify Flow to automatically add customer tags when orders include products from specific categories. These tags become reliable "category interest" signals you can market to.

Basic workflow structure:

  • Trigger: Order created
  • Condition: Order contains products from [category] (check product tags, collections, or product type)
  • Action: Add customer tag like interest-raw-materials, interest-components, or interest-finished-goods

Example Flow for raw materials buyers:

  1. Trigger: Order created
  2. Condition: For each line item, check if product tag contains raw-materials
  3. Action: Add tag interest-raw-materials to customer

Repeat this pattern for each product category you want to track. Once set up, customers automatically accumulate tags reflecting their purchasing patterns.

Step 2: Build Dynamic Segments from Customer Tags

With customers tagged, create dynamic segments using Shopify's customer segmentation tool:

  1. Go to Customers in your Shopify admin
  2. Click Segments > Create segment
  3. Build your rules in the query editor using ShopifyQL
  4. Click Run query to test, then Save segment

Example segment queries:

For raw materials buyers:

customer_tags CONTAINS 'interest-raw-materials'

For components buyers:

customer_tags CONTAINS 'interest-components'

For finished goods buyers:

customer_tags CONTAINS 'interest-finished-goods'

These segments update dynamically as customers gain or lose tags, keeping your audiences current without manual maintenance.

Prerequisite: Product Tagging

For this approach to work, your products need consistent category tags. Establish a tagging convention:

  • raw-materials: Base materials (steel, plastics, chemicals, textiles)
  • components: Parts that go into assemblies (fasteners, electronics, sub-assemblies)
  • finished-goods: Complete products ready for end use or resale
  • consumables: Items used up in operations (lubricants, abrasives, safety supplies)
  • tooling: Equipment used in manufacturing (dies, fixtures, cutting tools)

Apply these tags systematically across your catalog. If you're using a PIM or ERP integration, map these categories during product sync. For PIM integration guidance, see How a PIM Can Revolutionize Your B2B Shopify Store.

Combining Segment Criteria

Create more specific segments by combining customer tags with other factors using AND/OR operators:

High-value raw materials buyers:

customer_tags CONTAINS 'interest-raw-materials' AND amount_spent > 50000

Components buyers who haven't ordered recently:

customer_tags CONTAINS 'interest-components' AND orders_placed(since: -90d) = 0

New customers buying finished goods:

customer_tags CONTAINS 'interest-finished-goods' AND customer_added_date > -30d

You can edit the ShopifyQL query directly in the segment editor to build more complex conditions.

Using Segments for B2B Companies

For B2B operations using Shopify's company features, you can also think about segmentation at the company level.

Company Tags for Category Classification

Add tags to company records based on their primary purchasing pattern:

  1. Go to Customers > Companies
  2. Open the company record
  3. Add tags like primary-raw-materials, primary-components, or mixed-category

This classification helps when you need to target at the account level rather than individual buyer level.

Automating Company Classification

Use Shopify Flow to automatically tag companies based on order patterns:

Trigger: Order created

Conditions:

  • Order contains products tagged raw-materials
  • Company doesn't have tag primary-raw-materials

Actions:

  • Add tag primary-raw-materials to company

Build similar flows for each category. Over time, companies accumulate tags reflecting their purchasing patterns.

Cross-Sell Strategies by Product Category

Each buyer segment has different cross-sell potential. Target your efforts where they're most likely to succeed.

Raw Materials to Components

Customers buying raw materials may also need components for their manufacturing processes.

Cross-sell approach:

  • Identify components commonly used with the raw materials they purchase
  • Highlight convenience of single-source purchasing
  • Offer bundle pricing for materials plus components

Campaign example:

"You're already sourcing [material]. Did you know we also carry the fasteners and fittings commonly used with it? Consolidate your purchasing and simplify your supply chain."

Components to Finished Goods

Components buyers may have applications where finished goods would be more efficient than assembly.

Cross-sell approach:

  • Identify finished goods that incorporate components they buy
  • Calculate the value proposition (time saved vs. cost difference)
  • Offer samples or trial quantities

Campaign example:

"Building [assembly] from components? Our pre-assembled version saves you [X] assembly steps. Request a sample to compare."

Finished Goods to Consumables and Accessories

Finished goods buyers need supporting products to use what they've purchased.

Cross-sell approach:

  • Identify consumables and accessories that pair with their purchases
  • Set up automated replenishment reminders
  • Create accessory bundles

Campaign example:

"Your [equipment] works best with regular [consumable] replacement. Set up auto-replenishment and never run short."

Moving Buyers Up the Value Chain

Some customers might benefit from upgrading their purchasing pattern:

  • Raw materials buyer → pre-cut or pre-processed materials
  • Components buyer → sub-assemblies or kits
  • Basic finished goods → premium versions or bundles

Campaign example:

"You've been ordering [basic product]. Our [premium version] includes [additional features] and customers report [benefit]. Worth considering for your next order?"

Email Campaigns by Segment

With segments defined, create targeted email campaigns that speak to each group's priorities.

Raw Materials Segment Campaigns

Focus areas:

  • Price stability and contract pricing offers
  • Inventory availability updates
  • Volume discount thresholds they're approaching
  • New material grades or specifications

Subject line examples:

  • "Lock in pricing for Q2: Raw materials contract offer"
  • "[Material] stock update: Available for immediate shipment"
  • "You're $2,000 away from the next volume tier"

Components Segment Campaigns

Focus areas:

  • Technical updates and spec sheet downloads
  • New product introductions in their category
  • Cross-reference guides for competitive parts
  • Kitting and bundling options

Subject line examples:

  • "Updated specs available for [component family]"
  • "New [component type] now in stock"
  • "Cross-reference guide: Find compatible alternatives"

For adding technical documentation to your store, see Spec Sheet and CAD Downloads for Shopify Product Pages.

Finished Goods Segment Campaigns

Focus areas:

  • New product announcements
  • Accessory and consumable reminders
  • Warranty and service information
  • Case studies and application examples

Subject line examples:

  • "New arrival: [Product] now available"
  • "Time to reorder [consumable] for your [equipment]?"
  • "How [similar company] uses [product] in their operation"

Personalizing the Store Experience by Segment

Beyond email, use segments to customize what customers see on your store.

Personalized Product Recommendations

Configure product recommendations based on segment membership:

  • Raw materials buyers see related materials and components
  • Components buyers see compatible parts and sub-assemblies
  • Finished goods buyers see accessories and consumables

Segment-Specific Landing Pages

Create landing pages tailored to each segment:

  • Raw materials hub with pricing tables, availability status, and bulk ordering tools
  • Components catalog with filtering by specification, cross-reference search, and technical resources
  • Finished goods showcase with application guides, comparison tools, and bundle offers

Link to these from segment-targeted emails for a cohesive experience.

Custom Pricing by Segment

For B2B, you may offer different pricing structures based on what customers buy:

  • Volume-based pricing for raw materials buyers
  • Project-based pricing for components buyers
  • List pricing with loyalty discounts for finished goods buyers

For pricing configuration, see Customer-Specific Pricing on Shopify for B2B and Volume-Based Pricing and MOQs on Shopify.

Tracking Segment Performance

Measure how well your segmented approach is working.

Key Metrics by Segment

Track these metrics separately for each product category segment:

  • Average order value: Are cross-sell efforts increasing basket size?
  • Order frequency: Are targeted campaigns driving repeat purchases?
  • Category expansion: Are customers buying from additional categories?
  • Email engagement: Open and click rates by segment
  • Campaign conversion: Revenue attributed to segment-specific campaigns

Segment Migration Tracking

Monitor how customers move between segments over time:

  • How many raw materials buyers added components in the last quarter?
  • What percentage of components buyers tried finished goods?
  • Which cross-sell campaigns drove the most category expansion?

This data helps refine your cross-sell strategies and identify the most effective approaches.

Automating Segment-Based Actions

Use automation to act on segment membership without manual intervention.

Shopify Flow Automations

Welcome series by segment:

When a new customer's first order contains products tagged raw-materials, trigger a welcome series focused on volume pricing, contract options, and supply reliability.

Re-engagement by segment:

When a components buyer hasn't ordered in 90 days, trigger an email highlighting new products in their category or offering a returning customer discount.

Cross-sell triggers:

When a raw materials order ships, trigger a follow-up email suggesting commonly paired components.

n8n for Advanced Workflows

Common Segmentation Challenges

Mixed-Category Buyers

Some customers buy across multiple categories. Handle them by:

  • Creating a "mixed" segment for customers active in 2+ categories
  • Prioritizing based on highest-value category
  • Alternating campaign focus across their active categories

Changing Purchase Patterns

Buyer behavior shifts over time. Keep segments relevant by:

  • Using time-bounded criteria (purchases in last 12 months)
  • Reviewing segment definitions quarterly
  • Archiving customers who haven't purchased recently into separate inactive segments

Small Catalog Coverage

If your catalog doesn't clearly divide into categories:

  • Start with a simple two-way split (e.g., standard vs. custom products)
  • Segment by use case instead of product type
  • Focus on order characteristics (size, frequency) rather than product attributes

Getting Started

Begin with a straightforward implementation:

  1. Audit your product tags: Ensure consistent category tagging across your catalog
  2. Create three basic segments: Raw materials buyers, components buyers, finished goods buyers (adjust categories to match your business)
  3. Build one campaign per segment: Focus on the most relevant cross-sell opportunity for each
  4. Measure results: Track engagement and conversion by segment
  5. Refine and expand: Add more specific segments and campaigns based on what works

Product category segmentation helps you speak to industrial buyers in terms of what matters to them. A raw materials buyer cares about different things than a finished goods buyer, and your marketing should reflect that difference.
