How do i post customer receipts if they are net of deductions?

Hi userian You will have to select receive payment on the invoice, for the full amount, in the  Deposit to field select the undeposited funds account > save and close. 

You will then have to create a bank deposit: New+ > Bank Deposit > In the Account field ensure you have selected the bank account that the payment was received > Change the date of the deposit to the date you received the net amount > select the box to the left of the relevant invoice > in the account column within the 'add funds to this deposit' section enter/create a expense account relating to the agent fees > in the amount field enter the agents fee as a minus figure > add the VAT if applicable > save and close. If your bank account is connected you'll be able to match the deposit to the net amount showing in the for review page.
