ASSIST24 is the APP that allows you to centrally and completely manage the entire flow related to technical assistance and maintenance: creation, assignment, management and closure of a service call. You will be able to easily store data to code the company profile, customer, material, service, vehicle and business trip. In addition, you will be able to set call priorities, tax rates, units of measure and currencies that you manage. If you have employees, once your company is set up, you can create new operators who, by scanning QR Codes, can be linked to your company profile. In this way, all open, assigned and closed calls will be synchronized keeping the whole team updated in real time. Once the service call has been closed, the system will automatically generate a report in .pdf format that will be sent to the technician and to the email address of the customer entered in the registry. Thanks to the data import/export functions, you will be able to upload your master records into the system and export the details of the interventions performed to speed up reporting. ASSIST24 has a free trial period of 20 days (the trial period is calculated at the company level, taking as reference the first installation made by the work team).
