How do Partial Payments for Purchase Orders work with Xero?

When a Purchase Order is created in TradeGecko, a Bill is created in Xero debiting the Purchases ledger account with the Bill value. The Bill will then be shown in the Awaiting Payment section in Xero. As TradeGecko doesn't handle payments for Purchase Orders, a partial payment will have to be created for the Bill directly in Xero.
