Sales & Operations database
With both the Sales teams and the Operational teams working from the same database information only has to be entered once. They all have a different view of the information relating to what they need for dealing with the customer.
After the operational jobs / tasks are completed the database is updated instantly. There is no further admin requirement.
There is only one database to be updated, backed up and maintained. When an address or contact information is updated it only needs to happen one time.
When the sales team visit the customer there are no surprises, because they are informed of what the operational team are doing. Likewise if information has been updated by the sales call the operational team also know about it.
