The SMS ONE app (SMS ONE) is an application utilized by our network of affiliates to help manage work orders and streamline the onsite validation process into one simple system. It is fully integrated with the SMS One Affiliate Portal and creates real-time communication and work order visibility between the affiliates’ home office, crews and SMS Assist. The SMS ONE app improves the workflow process for both affiliate field technicians and administrators in the following ways: • Allows affiliate administrators to remotely monitor and manage the status of work order information in one place • Eliminates back-office costs and paperwork on every work order • The photo feature captures before and after pictures to ensure every service is completed to 100% satisfaction • The GPS-enabled functionality reduces technicians check in and out time to under one minute • The application has a simple messaging service that connects technicians with SMS Assist and reduces the need for time consuming follow-up calls • Provides easy map directions to each job site With the SMS ONE mobile app, managing your work orders and crews has never been easier. 【Note】 Route planning will continue to use location services and consumes more phone battery while active. Please note: the route planning and technician reporting continue using the GPS services while the app is running and will continue to consume battery power.

FieldVision by DTSI is a mobile application designed for property managers and field service providers to solve the problems that each face every day in the course of their work. Crews that go out into the field to perform work need a means of tracking that work and also proving to the client that the work has been done satisfactorily. Property owners and managers need a way to track and verify that the field service crews are performing the work required and that the work is done well. One of the biggest problems for field service companies and their clients (property managers) is the lack of visibility regarding the status of work to be performed at remote locations. Companies providing the services do not know exactly when services are to be completed and property managers are not notified when services are completed. This is particularly true of field services operations (snow removal, landscaping, facilities maintenance, etc.) whereby the customer or property manager is not at the property at the time of service. Because of this lack of communication, property managers and field supervisors often need to resort to phone calls to ask whether a property has been serviced or not and when the next service is scheduled. FieldVision solves these problems by giving field crews the ability to update their work status and to have that information made instantly available to their supervisors, customers and property managers. This capability provides a significant strategic and economic value to both service provider and property managers. Both property managers and field service companies have become inundated with unorganized collections of individual photos which are often sent back and forth via text messages and email. Property managers and service providers sometimes have so many photos of properties that the photos that they may want to find on a particular day have become lost among the thousands of photos on their devices and computers. FieldVision solves the problem of organizing photos by associated each photo with a property or work order. Features: Supports both English and Spanish Track work at one property or thousands of properties Create one-time work orders or work orders for recurring services (i.e. weekly, monthly, etc.) Supports data entry even if no internet connection is available Usable across all field service categories (i.e. lawn maintenance, snow removal, HVAC, janitorial, and many more) Keep a visual record of your properties and work associated with those properties Enter properties, create work orders and assign work orders to work groups Create work groups to group people who work on the same work orders Instantly share photos and work information (T&M, Fixed Price, etc.) with all parties in the workgroup Scalable from one person operations to enterprises with thousands of field service technicians and properties FieldVision is based on a REST API so that your enterprise can integrate it with your own work order tracking system if you like.
