One Stop Shop (OSS) provides multi-channel public services delivery to businesses and citizens in a single window. OSS model is a simplified mechanism for interaction between recipients and providers of public services through the organization of a single point of access (physical or virtual) for the reception, registration and issuance of the necessary documents to individuals and legal entities in rendering public services. Thus reducing the amount of time spent for applicant's interaction with government officials. One Stop Shop is a new approach to reforming public services, which contributes to reducing the number of procedural actions involved in this process by changing the way services are provided.
