With our long work and the contribution of our customers, the robot users identified in our projects started to convert more delivery notes into invoices than real users. As a result of studies carried out in many areas such as the company-based adjustable structure of the companies' e-invoice registration structures, the entry discipline of delivery note numbers on the hand terminal, the completion of product information, the guidance of companies with deficiencies, and the sorting of inconsistent data due to some gaps in the UBL structure, a high number of error-free matches were obtained. Thanks to the control-marking-classification-audit facilities that have been used in our e-Invoice system since the first day, the remaining e-invoices are also easily managed.In this way, extraordinaryTime and human resources are saved, and documents are processed with zero errors.With the systematic monitoring of price differences that DerinSİS has maintained for years, the entire cycle is monitored.Since it has been completed, our customers can enjoy this controlled experience.They are enjoying the power.
