From the deposit:
- Find the deposit & edit it then click "Apply this payment to an invoice" next to Regular Income
- Select the invoice you'd like to apply it to and save
- If needed, you can use the Split button at the bottom to split a deposit across different invoices or to different income types. Click the Split button at the bottom of the screen once to split the deposit into 2 parts. Enter the amount that you'd like to apply to the first invoice. Be sure to select "Apply this payment to an invoice" and select that invoice you'd like to apply that amount to. The 2nd portion of the split will be auto-calculated so that it is the remainder of the original deposit's total amount. Click "Apply this payment to an invoice" to select the invoice for that split or change the income type. If needed, you can continue to click the Split button if you need to apply it to more than just 2 invoices or income types.
