If you would like to have your bank details appear in a section at the bottom of your invoices created within Commusoft, this can be set up through your company settings. Go to the 'Bank details' section of the 'General settings' section.
This will take you to a page asking whether or not you'd like your details to appear on your invoices. Choose the 'Yes(...)' option and then fill out all the required information (mandatory fields marked with an asterisk). You will need to add a message to appear to your customers. This message will not be labelled so it can be as specific or generic as you would like, for example, 'Our preferred method of payment is via BACS'. Make sure to 'Save' once all the details have been entered.
Please note -- These details can later be amended if need be.
