You may come across a scenario where you have invoiced a deposit, however the deposit is not showing in the accounts receivable module.

The reason for this is usually because your depsosit product has not been set up as a 'Retainer' to resolve this go to Space>products and then edit your deposit product, the field that needs to be ticked is 'Retainer'

Once this has been ticked, the depsosit should show on the account.
