Inside every contact, there is the "Add transactions" option that allows you to submit receipts or payments massively for the outstanding sales and purchase documents. The procedure is the same whether it involves bulk invoice or purchase invoice payments.
In the following example we will record a payment from a client for multiple outstanding sales documents. From the main menu select "Contacts -> Select the desired -> Add transactions -> Invoice payments."
First, you enter the total amount of the receipt / payment, its date and the reason. If you received a payment in another currency than the default for the client , you can change it in the "GBP" field next to the "Amount". Τhe system will instantly inform you about the exchange rate on the specified date.
Below you are required to allocate this amount to outstanding invoices related to the contact. You can manually enter a number in each "amount" field or click on the "Pay-off" button and pay off the documents, provided that the receipt's amount is equal or greater than their total.
