Apply Sage Intacct Credit Memos During Checkout

1) Overview

Paystand now supports applying Sage Intacct AR Credit Memos directly during checkout.

This feature allows payers to use available credits toward outstanding invoice balances without requiring manual intervention. Credits are retrieved from Sage Intacct in real time and can be applied during the Checkout v5 payment experience.

Using credit memos during checkout helps:

• Reduce manual reconciliation
• Prevent overpayments
• Improve payment accuracy
• Simplify the payer experience

2) How Credit Memos Work

During checkout, eligible Sage Intacct AR Credit Memos are displayed in a new Apply Credits step.

Payers can select one or more available credit memos and apply them toward one or more open invoices.

The checkout experience automatically:

• Retrieves available credit memos from Sage Intacct
• Validates currency compatibility
• Applies credits to outstanding balances
• Updates payment totals in real time
• Preserves any unused credit balance in Sage Intacct

3) Supported Use Cases

Pay an Invoice Entirely with Credit Memos

If available credit memos fully cover the invoice balance, the payer can complete checkout without entering a payment method.

Example:

Checkout flow:

Apply Credits → Billing Address → Confirmation

Since no payment is required, the payment method step is automatically skipped.

Pay Partially with Credit Memos and a Payment Method

If credits only cover part of the invoice balance, the payer can apply available credits and pay the remaining amount using their preferred payment method.

Example:

Checkout flow:

Apply Credits → Payment Method → Review & Pay

Supported payment methods remain available based on merchant configuration.

Credit Memos with Fees and Discounts

Credit memos are fully compatible with existing checkout fee and discount functionality.

When applicable:

• Discounts are calculated according to existing checkout rules
• Payment method fees continue to be calculated normally
• Applied credit memos reduce the invoice balance before determining the final amount due
• The Payment Summary reflects all adjustments, including credits, discounts, fees, and remaining balance

4) Applying Credits During Checkout

Step 1: Select Credits

In the Apply Credits step, eligible credit memos are displayed.

Each credit memo includes:

• Credit Memo Number
• Issue Date
• Available Credit Amount

A summary of total available credits is also displayed.

Step 2: Choose Credit Memos

Select one or more credit memos using the available checkboxes.

The system automatically applies credits toward the selected invoice balance.

Step 3: Review Payment Summary

The Payment Summary updates in real time and displays:

• Selected invoice(s)
• Amount Due
• Credits Applied
• Subtotal
• Remaining Amount to Pay

5) Checkout Flow Behavior

Single Invoice

When Payment Is Still Required

Apply Credits → Payment Method → Review & Pay

When Credits Fully Cover the Invoice

Apply Credits → Billing Address → Confirmation

The payment method step is skipped because no payment is required. 

Multiple Invoices

When multiple invoices are available, payers first choose which invoices to pay.

When Payment Is Still Required

Select Invoices → Apply Credits → Payment Method → Review & Pay

When Credits Fully Cover Selected Invoices

Select Invoices → Apply Credits → Billing Address → Confirmation

The payment method step is skipped because the selected invoices have been fully satisfied by credits.

6) Credit Memo Eligibility Rules

To be available during checkout, credit memos must meet all of the following requirements:

• Credit Memo status is Posted in Sage Intacct
• Available Credit Amount is greater than zero
• Credit Memo currency matches the invoice currency

Only open invoices with an outstanding balance greater than zero are eligible for payment.
