Salesforce give you 20 fields as standard for your audit. If you’d like more, you have to pay extra for a third-party license and this is still capped at 65 fields in total. If you want to track who changed which values and when, you don’t get any history.
With Workbooks, you can track every change in the system to see who changed which values, and when. No field limits, and only £6 or $8.50 per user per month to use.
