Acesso em:.https://bdm.ufpa.br/handle/prefix/8567This study presents the development of a point-of-sale (POS) prototype for delivery, following a three-tier architecture and a fully Python-based stack: FastAPI (back end/REST), Kivy (front end/GUI), and MongoDB (NoSQL persistence). The goal is to provide an affordable, scalable, and customizable solution for small and medium-sized businesses, addressing common constraints related to cost, flexibility, and integration. The research is applied, exploratory-descriptive, and implemented incrementally with continuous testing and refinements. The prototype includes JWT authentication, CRUD for products and orders, real time status updates, and basic reporting. A qualitative assessment with a representative end user indicated operational improvements (faster service and cash closing, fewer errors, and better information retention). The work offers academic contributions (software-engineering practices and full-stack development), technological contributions (API–GUI–NoSQL integration), and practical value (a foundation for commercial evolution). We discuss strengths and limitations compared to market solutions and outline future work (analytical dashboards, payment-gateway integration, automated testing, mobile UX enhancements, and offline synchronization).Acesso AbertoPDVDeliveryFastAPIKivyMongoDBArquitetura cliente–servidorFull-stack PythonPOSClient–server architecturePython full-stackCNPQ::ENGENHARIASCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::METODOLOGIA E TECNICAS DA COMPUTACAO::ENGENHARIA DE SOFTWARETrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
