Good day, Sajeel.
In QuickBooks Online, generating an estimate from a purchase order is unavailable. You can, however copy an estimate to a purchase order, but take note that some items will be not be carried over. Here's an article for more details: Copy an estimate to a purchase order.
For creating 5 invoices from 1 estimate, you can use the Remove line to not include the other items for that specific invoice.
To record an Estimate, here's how:
- Go to Sales > Customers.
- Select the customer's name and click the New transaction drop-down.
- Choose Estimate.
- Select the customer from the drop-down menu and add the items that you will be invoicing later.
- Click Save.
Then, create an invoices from the estimate by following these steps:
- In the Estimate page, select the Create Invoice button and choose Create invoice when you get the How much do you want to invoice? pop-up window.
- Add the Invoice no. in the field and remove the other items by clicking on the trash bin icon beside the Amount column.
- When prompted, click on the Remove line button.
- Hit the Save and close.
Open the estimate again, and do the same steps until you're finished recording all 5 invoices.
Once done, you can click on the Receive payment link under the Action column to pay for invoice 1 and 2. I've got this article for reference: Record invoice payments in QuickBooks Online.
In sending the invoices 3, 4 and 5, you will need to open each invoice and click the Save and send button. Check out the steps in this article: Send an invoice.
With regard to linking the invoices 1 and 2, are you referring to match the payment downloaded from the Banking page? If so, you'll want to open this link for the instructions: Categorise and match online bank transactions in QuickBooks Online.
Please let me know if you're referring to something else. I'm just a few clicks away to help you some more. Take care and stay safe.
