1. Inventory Synchronization Bottlenecks at Enterprise Scale
Managing physical inventory across multiple regional warehouses, physical retail branches, and e-commerce storefronts presents a massive race-condition challenge.
If a physical point-of-sale (POS) terminal processes a barcode scan in a retail store at the exact millisecond an online customer completes checkout, un-synchronized databases cause double-fulfillment errors. SoftSolex resolves this with pessimistic event-driven locking. Explore our dedicated Business Informatics, CRM & ERP Capability for full solution details.

services/erp/inventoryService.ts Transactional PostgreSQL Handler
import { db } from '../db/client';
export async function processStockMovement(sku: string, qtyDelta: number, branchId: string) {
return await db.transaction(async (tx) => {
// Pessimistic row lock to prevent flash sale race conditions
const item = await tx.query(
`SELECT current_stock, safety_stock FROM inventory WHERE sku = $1 AND branch_id = $2 FOR UPDATE`,
[sku, branchId]
);
const newQty = item.rows[0].current_stock + qtyDelta;
if (newQty < 0) throw new Error("INSUFFICIENT_STOCK_EXCEPTION");
await tx.query(
`UPDATE inventory SET current_stock = $1 WHERE sku = $2 AND branch_id = $3`,
[newQty, sku, branchId]
);
// Auto draft supplier purchase order if stock falls below safety metric
if (newQty <= item.rows[0].safety_stock) {
await tx.query(`INSERT INTO supplier_po_drafts (sku, quantity) VALUES ($1, 500)`, [sku]);
}
});
