# Pay Invoice

The **Pay Invoice** module lets you collect payment against an existing open invoice on a customer's account — without creating a new sale. This is the standard workflow for customers who purchase on credit terms (net 30, net 60, etc.) and settle their balance later.

> **Note:** Pay Invoice is an out-of-the-box module available by default. Cashiers and Store Managers typically have access. If it's not visible in your sidebar, your admin may not have added it to your workflow yet.

## When to Use Pay Invoice

Use Pay Invoice instead of Place Order when:

* A customer is not buying anything new — they are paying off what they already owe
* The customer has received an invoice by email or mail and wants to settle it in person or over the phone
* A B2B account has multiple open invoices and wants to make a partial or full payment

***

## How to Pay an Invoice

1. Open **Pay Invoice** from your sidebar.
2. In the customer search field, type the customer's name, company, or email and select their account.
3. The screen will display all **open invoices** for that customer, showing:
   * Invoice number
   * Invoice date
   * Due date
   * Amount due
4. Select the invoice (or invoices) you want to collect payment on.
5. The payment total will update automatically based on your selection.
6. Choose a **payment method:**
   * **Cash** — enter the amount tendered; change is calculated automatically
   * **Card** — follow the card terminal prompts
   * **Store Credit** — applies available credit on the customer's account
   * **Split Payment** — use more than one method if needed
7. Click **Complete Payment**.
8. A receipt or payment confirmation will be available to print or email.

## Paying Multiple Invoices at Once

You can select more than one invoice in a single session:

* Check each invoice you want to include
* The total will update to reflect the combined amount
* Process payment as normal — one payment transaction covers all selected invoices

***

## Partial Payments

If a customer wants to pay part of an invoice (for example, pay $500 of a $1,000 invoice):

1. Select the invoice
2. In the amount field, enter the partial amount instead of the full balance
3. Complete the payment
4. The invoice will remain open with the remaining balance updated in the system

> **Note:** Whether partial payments are allowed may depend on your store's policy and system configuration.

## What Happens After Payment

* The invoice status updates in NetSuite to reflect the payment
* The customer's outstanding balance decreases accordingly
* A payment record is created and linked to the original invoice
* If fully paid, the invoice is marked as **Closed**

| Customer's invoices are not showing          | Confirm you have selected the correct customer account — check spelling or search by email                 |
| Invoice is missing that the customer expects | The invoice may be assigned to a different contact on their account; ask your manager to check in NetSuite |
| Payment method is not available              | Contact your manager — payment method availability is controlled by your workflow configuration            |
| Partial payment not allowed                  | Your configuration may require full payment; ask your manager to process a manual adjustment if needed     |
