Having a cloud-based system alleviates most of these issues.
Employees can enter field notes and data directly into the system while in the field using a phone, laptop, or tablet, eliminating the issue of duplicate entry. If they need to verify a measurement, they are still on site and can collect the data again.
In the same way, time can be entered from wherever they are, helping to ensure their timesheets are always up-to-date and accurate.
By having cloud-based, interconnected CRM, HR, project management, and ERP systems, field personnel no longer have to return to the office to enter data into business applications, which results in significant time savings and reduces the increased chance of human error. Plus, it frees up your staff to perform more billable work.
