Case Study: Credit Card Preauthorization & Order-to-Cash Optimization in NetSuite

Customer Challenge

The customer operates in a fast-paced sales environment where most customers are set to Terms: Due Upon Receipt. This required collecting payment immediately, but their existing NetSuite process presented several challenges:

  • No ability to preauthorize credit cards at the sales order level.
  • Risk of fulfilling and shipping orders without guaranteed funds.
  • Limited flexibility for sales reps to apply credit memos directly to sales orders.
  • Shipping costs entered at order entry were often estimates and differed from the final carrier charges.
  • No automated way to handle credit card authorization changes when order values changed after fulfillment.

The customer needed a secure, flexible, and automated solution that protected cash flow while improving operational efficiency.

Solution Overview

We designed and implemented a custom NetSuite order-to-cash workflow that introduced credit card preauthorization, dynamic payment handling, and accurate final billing — all while maintaining strict financial controls.

Key Process Enhancements

1. Credit Card Preauthorization at Sales Order Stage

  • Sales reps can preauthorize a customer’s credit card directly from the sales order.
  • The preauthorization validates available funds before fulfillment begins.
  • The authorized amount dynamically reflects:
    • Order total
    • Any custom-applied credit memos

Business Impact:

Prevents shipping without secured funds and reduces payment failures.

2. Credit Memo/Payments Application on Sales Orders (Custom)

  • Sales reps can apply approved credit memos directly to the sales order via a custom mechanism.
  • The system automatically:
    • Adjusts the authorized amount
    • Tracks applied credits for downstream transactions

Business Impact:

Improved sales flexibility without compromising accounting control.

3. Shipping Cost Adjustment at Item Fulfillment

  • Sales orders initially use estimated shipping costs.
  • At the item fulfillment level, the actual carrier shipping cost is calculated.
  • If the shipping cost increases, the total order amount changes accordingly.

Business Impact:

Ensures the customer is charged the true cost of shipping.

4. Automated Credit Card Authorization Handling

  • When the shipping cost increases at fulfillment:
    • The original credit card authorization / capture is no longer valid.
  • Upon cash sale creation:
    • A scripted process automatically voids the original authorization or capture.
    • A new charge is created for the final, correct order total.

This guarantees that the customer is never over- or under-charged and avoids partial or duplicate authorizations.

Business Impact:

Accurate payment capture with full automation and auditability.

5. Final Cash Sale Charge with Credit Memo Reconciliation

  • The system generates a cash sale once items are picked and packed.
  • The final charge amount automatically:
    • Includes the updated shipping cost
    • Subtracts any credit memos applied on the sales order
  • No manual recalculation is required.

Business Impact:

Seamless reconciliation between sales, fulfillment, and accounting.
