I need to generate a bulk remittance for a supplier

Hello, accounts-ctilogi.

I'll help you generate supplier remittances in bulk in QuickBooks Online.

If you're trying to generate bill payments (remittance advices) all at once, you can use the Pay bills function. Simply click the + New icon, then select Pay bills. 

From there, you can check the bills you want to pay to generate the remittances. 

However if you're trying to send multiple remittance to your supplier, we're unable to do it in bulk. Though, you can print or save your bill payments as PDF and send them to your suppliers manually. 

Here's how: 

1. Go to Expenses, then click the Suppliers tab.
2. Select your supplier.
3. Open the Bill Payment (Cheque) transaction. 
4. Click the Print menu.
5. On the preview page, click Print or Download. 

Do you need to connect your bank so you can categorize your bank transactions with your QuickBooks records? Feel free to check this article for a guide: Connect bank and credit card accounts to QuickBooks Online.

I'm ready to help you out again if you need something else to do with your remittances. If you have any other concerns, add them to your reply and I'll see what I can do for you.
