AQL per Style — a separate sample size for each style, ideal when each style needs its own inspection report. • MAJOR & MINOR AQL Set different AQL values for Major and Minor defects. Popular defaults like AQL 2.5 and AQL 4.0 are pre-loaded and easy to switch. • GENERAL & SPECIAL INSPECTION LEVELS Choose General Level I, II, or III for sample size. Choose Special Level S1–S4 for measurements and testing. • UPLOAD PACKING LIST Import Excel (.xlsx, .xls) or CSV packing lists. The app automatically detects columns like Style, Description, Color, Size, Quantity, and Cartons. Review the mapping before extracting — you stay in control. • PROPORTIONAL DISTRIBUTION Sample size and carton count are automatically distributed across every Style → Color → Size position, based on each position's share of the total quantity. • CARTON SELECTION Calculates how many cartons to select using the square root of the total carton count, distributed proportionally. • PICK QTY PER CARTON Shows how many pieces to pick from each selected carton to complete your sample. • AQL CHART & REFERENCE TABLES Built-in Table I (sample size by lot size) and Table II-A (Ac/Re by sample size) for quick reference — no need to carry a printed AQL chart. • SAVE & REUSE Save any calculation with a file name. Reopen it later to view, edit, or reuse. Merge rows from a saved file into your current calculation. • EXPORT & SHARE Download results as Excel or CSV.
