Thanks for reaching out to us, Juvet.

You'll have to sign up for QuickBooks Payments so you can create and send an invoice to your customer. Then, this allows them to pay you when they choose Pay Now right from that invoice. Let me walk you through the steps.

1. Select + New.
2. Select Invoice.

3. Select the type of payment you'll accept under Online Payment.

4. Enter the invoice details, including your customer's email address.
5. Click Save and send.
6. Review the invoice in the Send email window. You can add any additional information to the subject line and body of the email.
7. Select Save and close.

Once done, this will turn on your online payments. 

For future reference, you can match transactions in QuickBooks Online (QBO): Add And Match Downloaded Bank Transactions.

If there's anything else you need, let me know so I can help.

@MariaSoledadG Thank you,

But let me explain what is my issue.

Hello there, Juvet,

You'll want to check out a third-party application to enable this. GoCardless integrates directly into QuickBooks Online.

Here's how:

1. Click Apps on the left pane.
2. Search GoCardless.

Feel free to reach out if there's anything else that you need.

I just read that Online payments are turned off because the currency of the invoice (XAF) does not match my business currency (USD).

Could you confirm that?

Let's make sure that your customer is set up for multicurrency, Juvet.

Once multicurrency is turned on, the next step is to set up your customer for this option. This way, when you create an invoice, the system will automatically detect ist currency. 

Just a heads up, you'll have to assign their currency before adding them. Hence, you're unable to assign one once they're already in the system.

I'll show you how:

1. From the Sales tab, select Customers.
2. Click New customer, and then enter their information.
3. Go to the Payment and billing tab.
4. Select your customer's currency in the This customer pays me with field.
5. Click Save.

Please let me know if there's anything else you need. Thanks for dropping by and stay safe!

I think you don’t read all I wrote.

All my settings for the Customer are correct. And I just got the confirmation on what I posted previously, I can’t enable Online payments in other currency except to subscribe to SYNDER.

 I upgraded to Essentials only for multi currency.

Because I can’t go back to Simple Start, I decide to invoice my overseas customers in USD and in MEMO write the rate of exchange of the day. 
Seriously disappointed.
