Q: Would we need a license for each and every member of staff accessing Quickbooks through Complete Contact CRM?

A: No. All you need is 1 license for someone to send all information to QuickBooks in a batch. If you want to allow each individual user to send information to QuickBooks then yes, all users will need a license. Also, remember that QuickBooks has concurrent licenses. For example, if you have 5 QuickBooks licenses you can have 20 users in QuickBooks but only 5 can be on Quickbooks at any given time from the same company.
