B2B Checkout Customization Checklist

Here’s your B2B checkout customization checklist. It’s designed for real-world complexity: multi-location buyers, layered approval flows, industry-specific compliance, and integration into the ERP jungle.

Make your checkout work the way your buyers do.

Payment Terms & Flexibility

✓ Enable Net Payment Terms (e.g., Net 30, Net 60, Net 90)

✓ Auto-assign terms by customer group, contract, or credit profile

✓ Support for split payments across:

• Cost centers
• Departments
• Internal accounts

✓ Allow partial payments and deposits (with rules by order type/value)

✓ Integrate 3rd-party financing or leasing providers

✓ Let buyers save multiple payment methods (card, ACH, invoice)

✓ Apply payment limits based on role, hierarchy, or budget caps

Purchase Orders & Invoicing

✓ Accept PO uploads or PO number entry at checkout

✓ Auto-match POs to contracts or saved buyer templates

✓ Trigger invoice generation post-checkout

✓ Sync invoices to ERP in real-time or batch mode

✓ Support tax-exempt flows (auto-validate certs)

✓ Display real-time credit availability from ERP

User Roles & Buyer Permissions

✓ Support multiple user roles per account (e.g., Buyer, Approver, Finance)

✓ Assign checkout permissions by user level

✓ Include role-specific checkout experiences (e.g., pre-filled defaults for junior buyers)

✓ Configure approval routing before order submission:

• Single approver
• Sequential approval
• Threshold-based auto-approval

✓ Track order history per user and per account

✓ Enable self-service reordering, order editing, or cancelation (role-restricted)

Smart UX & Custom Logic

✓ Show/hide fields based on:

• Buyer type
• SKU type
• Shipping region

✓ Autofill address, payment, and tax details for repeat customers

✓ Conditional validation (e.g., require PO only for orders over $5,000)

✓ Show/hide SKU-level compliance flags or warnings

✓ Support headless checkout (embedded in distributor portals, apps, etc.)

✓ Branded checkout experience with dynamic field labels and UI skin

✓ Localize currencies, payment options, and tax logic by market

Shipping & Fulfillment Rules

✓ Dynamic shipping method selection based on:

• SKU attributes (e.g., hazmat, oversized, refrigeration)
• Destination
• Contract terms

✓ Multi-location shipping:

• Route items to different warehouses
• Split shipping by line item
• Assign freight by item or pallet

✓ Integration with real-time freight and 3PL APIs

✓ Add embedded delivery instructions or compliance forms

✓ Offer negotiated shipping rates per buyer or contract

✓ Embed delivery terms into final screen

Integrations & Data Flow

✓ Real-time sync to ERP (orders, inventory, credit, tax, invoicing)

✓ CRM sync to attribute customer behavior to rep performance

✓ Tax compliance integration (Avalara, TaxJar, Vertex)

✓ Custom field mapping for industry-specific data (NAICS, HS Codes, etc.)

✓ API fallback logic — what happens if the tax/payment engine fails

✓ Create analytics hooks at:

• Form fill
• Field errors
• Order submission
• Payment failure

Reporting, Audits & SLA Enforcement

✓ Trigger alerts on checkout drop-off above baseline

✓ Track time to complete by buyer segment

✓ Monitor failed payments by reason (auth decline, terms error, API timeout)

✓ Audit logs for:

• Role-based approvals
• Cart edits
• Payment changes

✓ SLA monitoring (e.g., is shipping quote shown within X seconds?)

✓ Roll-up reporting to sales and ops teams

Reorder & Post-Checkout Experience

✓ Save full cart templates by buyer

✓ Reorder from order history (one-click reorder or reorder + edit)

✓ Show expected ship date or SLA window

✓ Allow buyers to clone orders to different cost centers

✓ Email + dashboard confirmations with payment/PO details embedded

✓ Enable self-serve order tracking via portal

A great checkout doesn’t just capture the sale.

It removes risk, respects your buyer’s time, and reinforces trust.
