Syncing prepayment invoices with Mews is entirely automatic once you enable the setting for your integration. When a finalized prepayment invoice is paid in full (the amount due is $0) the invoice will automatically be synced with Mews. This will cause:
A Closed bill will be created in Mews under the Booking's Paymaster
One charge per tax will be created on the bill
Each payment will be added to the bill
Dated Today
2. An open order will be created for the negative balances
This bill will have the same charges added to the first bill, but negative values
Dated on the Booking End Date
If the prepayment invoice is paid after the Booking is finished, we will still use the Booking End Date if it is within the editable history. If it is outside of the editable history, we will use the last payment's payment date. If neither of these is within the editable history, we will use the current date/time.
