You may wish to send quotes to one contact within your customer's business, completed jobs to another, and invoices to a third. Or a mix of all three and visa versa you may wish to ensure that the person who you send completed jobs to, never receives any financial information such as quotes or invoices.
This is simple to do in Onsite Pro. Firstly click on contacts from within a customer management screen (see below) where you will see the current contact and what they will receive (JS: Job Sheet. In: Invoice Qu: Quote) then click 'Actions' and 'Create new'
Then from in this section, you can add multiple contacts and select which kind of alerts they receive... an alert will be an email notifying them of a new quote, job, or invoice with a link to the relevant document.
You will see these options when you send your document (job sheet or quote or invoice) which will be covered in another section.
