Invoicing and payments

I can help you record the payments you've received to maintain an accurate financial record, @vksmith.

To keep an accurate record of your payments, you can record the $100 you've received to  apply it to the invoice automatically. Once you've done this, record the other $400 to apply it to the second invoice automatically.

The first invoice will be marked as paid, and the remaining $250 will be considered an unapplied payment for that customer, which can be applied to the second invoice.

Here's how to record a received payment transaction for the first invoice:

1. Go to the + New button and choose Receive payment.
2. Set the Customer, Payment method, and all the necessary information. 
3. In the Amount received field, enter 100. 
4. In the Outstanding Transactions section, select the checkbox for the first invoice for which you're recording the payment.
5. Select Save and Close.

Repeat the entire process in recording the $400 payment. Once done, process a receive payment transaction for the second invoice. Here's how:

1. Go to the + New button and choose Receive payment.
2. Set all the necessary information.
3. In the Outstanding Transactions section, select the checkbox for the second invoice.
4. Scroll down to the Credits section and click the $250 open balance checkbox.
5. Click on Save and close once you're done. 

Now, both invoices are marked as paid, and you can easily track the two separate payments of $100 and $400 from the All Sales tab.
