The current pandemic saw a surge in the demand of vegetable seeds in the Philippines. Farmers continue to try new vegetable crops using seeds in small packets. This positive market development amidst the uncertain times necessitated the need for a new sales forecasting system for business organizations distributing seed products. A systems analysis of the current process observed in typical seed distribution operations confirmed an opportunity for a computer-based forecasting system. During the Systems Design phase, a Hierarchical Input-Process-Output chart, a Use Case Diagram and Data Flow Diagrams were generated. Microsoft Access was used to develop the database. Tables, queries, forms, and reports were likewise generated. Low fidelity prototyping was used using Justinmind. Compared to the current process, the new system provided several advantages. None bigger was the flexibility and capability afforded by the new system to a seed distributor, in strengthening the forecasting process to cope up with the growing demand for vegetable seeds amidst the uncertainties brought about by the pandemic.
