Generally, billwerk performs the account reconciliation automatically. However, if there are incoming payments that could not be automatically matched, these payments can be assigned manually. To do this, go to "Activities > Account Reconciliation". There you immediately see all unassigned incoming payments. You can then decide whether you want to assign or ignore these payments.
To assign a payment, click on "Assign", now you have two options.
A) You can assign the payment to a contract, then this payment generates a new entry in the contract ledger and changes the account balance.
B) You can assign the payment to an "unconfirmed" payment that already exists in the contract ledger. This does not change the account balance but confirms the previously unconfirmed payment.
If you want to execute A), press "Assign" and use the search function to identify to the desired contract. Now select the contract you want to asign the payment to, adjust the amount if applicable and press "Assign" to complete the action.
If you want to execute B), press "Assign" and use the search function to identify to the specific unconfirmed transaction you want to assign the payment to. Select the individual payment transaction (square box), not (!) the round button besides the customer and click on "Assign".
You now can repeat this process for all all payments you want to assign.
