Enabling Partial Payments for an Invoice
There are two ways to enable partial payments.
1. Go to Settings > System Preferences, and from there select the Statements tab.
2. Tick the box labelled Always allow clients to make partial payments for invoices.
3. Click Save.
With this all your invoices can receive partial payments from clients. The moment a client views your invoice and agrees to pay, the client has the option to pay any portion of the amount for the particular invoice.
