Install

npm install @ph-itdev/ph-warehouse-toolkit

Quick Start

import { formatPeso, calculateVAT, generateSKU, isWarehouseOpen } from '@ph-itdev/ph-warehouse-toolkit';

// Philippine Peso formatting
formatPeso(125000);        // ₱125,000.00

// BIR VAT calculations (12%)
calculateVAT(1000);        // 120

// SKU generation
generateSKU({ prefix: 'WH', category: 'EL', sequence: 1 });  // WH-EL-000001

// Warehouse scheduling
isWarehouseOpen(new Date());  // true/false

Modules

💰 Currency

import { formatPeso, parsePeso, formatPesoShort, calculateVAT, addVAT, extractVAT } from '@ph-itdev/ph-warehouse-toolkit/currency';

formatPeso(1234567.89);        // ₱1,234,567.89

parseSKU('WH-EL-000042');  // { prefix: 'WH', category: 'EL', sequence: 42 }
calculateReorderPoint(50, 7);       // 350
calculateEOQ(1000, 50, 5);          // ~141
calculateStockValue([{ quantity: 100, unitCost: 50 }, { quantity: 50, unitCost: 120 }]);  // 11000

🏷️ Barcode

calculateEAN13CheckDigit('400638133393');  // 1
validateEAN13('4006381333931');           // true

📄 Documents

import { generateGRNNumber, generateDRNumber, generateReferenceNumber } from '@ph-itdev/ph-warehouse-toolkit/documents';

generateGRNNumber({ warehouseCode: 'WH01', date: new Date('2026-06-15'), sequence: 1 });
// 'GRN-WH01-20260615-0001'
generateDRNumber({ warehouseCode: 'WH01', date: new Date('2026-06-15'), sequence: 1 });
// 'DR-WH01-20260615-0001'

Why This Package?

Warehouse management in the Philippines has unique requirements:

• Philippine Peso (₱) — proper currency formatting with peso sign
• BIR Compliance — 12% VAT calculations, TIN validation
• PH Address System — regions, provinces, cities, barangays
• Local Holidays — regular + special non-working holidays for scheduling
• SKU & Inventory — generate warehouse SKUs, calculate reorder points
• Document Numbering — GRN, DR, and PO reference numbers
