How to Customize the Shopify B2B Checkout

The B2B checkout experience is often the last thing merchants think about when setting up wholesale, even though it is the moment where a buyer's procurement expectations, PO numbers, net terms, specific shipping needs, either get met smoothly or create friction right before the sale closes.

Customizing this experience does not require custom development for most needs, since native B2B and a dedicated wholesale app together cover the specific fields and payment flexibility most business buyers expect.

This guide is for merchants wanting to customize the Shopify B2B checkout experience specifically, walking through what fields and options can actually be configured.

Quick Answer

Yes, the Shopify B2B checkout can be customized through native settings and a dedicated app without custom development. Native B2B includes PO number fields and net payment terms of 7 to 90 days, and Wholesale Pricing Discount B2B adds wholesale discount codes, flat or advanced shipping rules by price or weight, and early payment discounts, all configurable through settings rather than requiring a developer.

What Can Actually Be Customized in the B2B Checkout?

The B2B checkout can be customized to include a PO number field for buyer-side approval processes, net payment terms instead of upfront payment, wholesale-specific shipping rates that differ from retail, and discount codes segmented to specific customer groups. Most of this customization happens through configuration settings rather than custom checkout code.

Who Needs to Customize the B2B Checkout?

• Wholesalers whose buyers require a PO number field for internal approval
• Stores wanting to offer net payment terms instead of immediate payment
• Sellers wanting wholesale-specific shipping rules distinct from retail rates
• Businesses wanting to run wholesale discount codes for specific customer segments
• Brands wanting checkout to reflect the buyer's actual account type and negotiated terms
• Teams without in-house development resources for a custom checkout build
• Companies wanting checkout customization achievable through settings alone

Why B2B Checkout Customization Matters for Your Business

• PO number support matches how business buyers actually process purchases internally
• Net terms improve conversion by matching how B2B buyers expect to pay
• Wholesale-specific shipping rules reduce disputes over unexpected shipping costs
• Segmented discount codes let you run targeted wholesale promotions
• A checkout that matches buyer expectations reduces abandoned carts
• Achieving this without custom development keeps the project fast and affordable
• Getting checkout right protects the final, critical moment of the wholesale sale

How to Customize the Shopify B2B Checkout

Step 1: Prepare Your Store and Customer Tags

Decide which checkout elements your buyers actually need before configuring anything, since not every business buyer expects every possible customization.

• Confirm whether your buyers require PO numbers at checkout
• Decide which customer groups qualify for net terms versus upfront payment
• Create customer tags reflecting checkout eligibility for each group

Step 2: Install and Configure Wholesale Pricing Discount B2B

Install Wholesale Pricing Discount B2B to add wholesale discount codes, advanced shipping rules, and early payment discounts through settings, without custom development.

• Connect the app and review plan options for shipping rules and discount codes
• Set net 15, 30, 45, or 60 payment terms per qualifying customer group
• Configure wholesale discount codes, either percentage or fixed amount

Step 3: Create the Pricing or Discount Rules

Build the shipping and discount logic that should apply automatically once a wholesale buyer reaches checkout, confirming it works alongside their existing tier pricing.

• Set flat wholesale shipping rates or advanced rules by price or weight
• Set early payment discounts for buyers who settle net terms invoices ahead of schedule
• Configure automated payment reminders by email and SMS for net terms accounts

Step 4: Test With a Tagged Test Customer

Test the full checkout flow with a tagged test account before offering it to real buyers, confirming every configured field and term displays correctly.

• Complete a test checkout and confirm PO number and net terms fields display correctly
• Apply a wholesale discount code and confirm it applies at the correct rate
• Ask Sidekick which groups have net 30 terms set up to confirm the checkout configuration matches your plan

Step 5: Go Live

Once checkout tests correctly for every scenario, publish it live and monitor the first cycle of orders closely.

• Publish the customized checkout to your live store
• Notify wholesale accounts of any new checkout fields or payment options
• Monitor the first cycle of checkouts for accuracy across PO numbers and terms

B2B Checkout Customization Examples

Office Furniture Supplier (Office supplies)
Problem: Business buyers needed a PO number field at checkout for internal purchasing approval, which the default checkout lacked.
Setup: Enabled native PO number support at checkout alongside net 30 terms configured entirely through settings.
Result: Buyers completed checkout with PO numbers without any custom development work.

Cleaning Supply Distributor (Industrial goods)
Problem: Applied one flat shipping rate to all wholesale orders regardless of weight, cutting into margin on heavy orders.
Setup: Set advanced shipping rules by weight through Wholesale Pricing Discount B2B, configured entirely through app settings.
Result: Shipping costs matched actual order weight, protecting margin without any custom development.

Best Practices

• Confirm which checkout fields your buyers actually need before adding complexity
• Reserve net terms for accounts with a track record of on-time payment
• Set shipping rules based on real cost data, not a flat estimate
• Test checkout end to end, not just individual field display
• Keep discount codes segmented so promotions reach the intended audience
• Review payment reminder timing so it feels helpful, not aggressive
• Achieve customization through settings before considering custom development

Summary

The Shopify B2B checkout can be meaningfully customized, PO numbers, net terms, wholesale shipping rules, discount codes, entirely through native settings and a dedicated app, without requiring custom development for most business needs. Getting this final checkout moment right protects the sale at the exact point where buyer expectations either get met or create friction.
