Can I accept visa gift cards on QuickBooks? I have a customer attempting to use one and it keeps declining.

Glad to see you here, @MerchNMore,

Yes, you can manually track gift certificate payments in QuickBooks Online. To get started, you can set up the GC accounts first using the steps below:

1. Tap the Chart of Accounts then click New.
2. For  the Account Type drop-down, choose Other Current Liabilities.
3. Pick Trust Accounts - Liabilities for  the Detail Type.
4. Enter the name of the account, example, GC Issued.
5. Hit Save and Close.

Once done, create a service item for the gift certificate that we will link to the account previously created. Here's how:

1. Tap the Gear icon, then choose Products and Services.
2. Pick New and select Service.
3. Add the name Gift Card in the Name field.
4. In the Income account drop-down, select GC Issued.
5. Click Save and close.

Now, you can create an invoice to redeem the gift certificate. Here's how:

1. Tap the Plus (+) icon, then select Invoice.
2. Find and select the customer's name.
3. On the first line, select the Item being bought.
4. Add the amount.
5. On the second line, select the Gift Card (the one linking to a liability account), and enter a negative amount.
6. Hit Save and close.
