Whist using Manual Payments there are some options you will need to action:
1, If you are using DBT ( Direct Bank Transfer ), Paypal or any other manual payment option, when the money has been deposited into your account, you will need to update the Order Status to COMPLETED.
This will ensure that the paid amount is added to the the "Total Payment" amount and your customer will be able to see this in their account.
All order transactions will need to have the Order Status as COMPLETED when finalised.
The final payment says l need to pay a minimum deposit amount?
If you have reached the final payment and you have not been updating the Order status to completed, then you will receive the above message ( minimum deposit amount, required ) all order status will need to be updated for the final payment to be successful.
