Create a supplier reliability analysis tool for small businesses that need to make purchasing decisions using incomplete and inconsistent delivery records.
Users can import purchase orders, promised delivery dates, actual receipt dates, quantities ordered, quantities received, prices, and supplier identifiers.
Build features that:
Calculate delivery delays, fulfillment rates, partial deliveries, and price variability.
Separate supplier performance from delays caused by missing internal records or incomplete receiving data.
Analyze reliability over time instead of relying solely on lifetime averages.
Compare suppliers for the same item or category using configurable criteria.
Estimate the probability of receiving an order within a selected lead-time window when sufficient historical observations exist.
Flag suppliers with too little data for reliable comparisons.
Simulate the impact of delayed deliveries on stock availability and planned purchases.
Generate supplier review summaries with evidence and suggested follow-up questions.
Include interactive charts, supplier comparison tables, data validation, and CSV exports.
Do not manufacture reliability probabilities from insufficient data. Show sample sizes, distinguish observed performance from forecasts, and allow users to adjust assumptions about future lead times. Keep commercial recommendations transparent and editable.
