It's common to work with advance payments. Customers pay part of the invoice for products or services to be delivered. After the products or services are delivered, the remaining amount is paid. Within InformerOnline, it's also possible to process partial payments.

The invoice is €121, but the payment is half: €60.50. As a result, the payment does not balance with the invoice, and the transaction cannot be saved. You will need to link an additional amount of -€60.50.

To save the booking, you need to manually adjust the linked invoice to €60.50. This does not change the invoice itself, but only the amount to be linked. After doing this, the booking will be balanced.

After linking the partial payment to the invoice, the payment is registered. The invoice will now show a payment of €60.50. The remaining amount of €60.50 will need to be processed later.
