My invoices are often paid in a group therefore they are not being matched and my income is showing as double. How do I manually match payments to more than 1 invoice

Hi easterbrookresto, thanks for joining the Community. 

You can match multiple invoice payments together by creating a manual bank deposit. To do this, on the 'receive payment' screen of each invoice, select the 'undeposited funds' account on the 'deposit to' drop-down (you can enter all other details of the payment, such as the date, on this screen as usual). Once the payments have been recorded against each invoice, create a bank deposit (via + New > Bank deposit). Tick all payments that apply under 'Select the payments included in this deposit' and then choose the correct date and bank account under 'account'. Once saved, you can then match this to the payment in your bank feed.
