What Is zStox 

zStox is a tax-compliant inventory management automation software built for growing businesses – combining invoicing, order management, procurement-linked stock visibility, and warehouse operations in one connected system, so billing, compliance, and inventory data never fall out of sync. It handles GST compliance out of the box for businesses in India, and standard tax requirements for businesses operating elsewhere

Pre-Configured · Industry-Specific · Enterprise-Scalable 

The Friction Point

  • Tax compliance on every invoice, tracked manually across spreadsheets and invoices instead of handled automatically.
  • Stock levels disconnected from procurement, so purchasing decisions get made without a real read on what’s actually on the shelf or shop floor.
  • Order status and inventory levels out of sync across teams, warehouses, and locations.
  • Manual tax calculation on every sales order, with room for costly errors.
  • No real-time visibility into stock across warehouses, leading to stockouts or overstock, a particular risk for manufacturers tracking raw materials alongside finished goods.

This is exactly where ecommerce process automation tools and warehouse management automation are supposed to help and where most growing businesses are still working manually.

Core Modules & Capabilities

Tax-Compliant Invoicing

Invoices generated to meet local tax requirements, including GSTIN records and HSN/SAC codes for businesses operating in India.

Automated Tax Calculation

The correct tax rate applied automatically based on your business’s tax preference and jurisdiction, no manual calculation on every order.

e-Way Bills & Delivery Challans

Generated directly from invoices, credit notes, or delivery challans, with full transport details, where regionally required.

Order Management

Sales and purchase orders, packages, and shipments managed and tracked from one order management system.

Procurement-Linked Inventory

Stock levels feeding directly into purchasing decisions, so procurement teams, including those running ProcurGenie, work from the same real-time numbers as the warehouse.

Warehouse & Production Stock Sync

Inventory tracking and order fulfillment across multiple warehouses and production sites, with real-time data insights for manufacturers tracking raw materials through to finished goods.

Barcode Inventory Tracking

Barcode-based stock movement to reduce manual errors and speed up fulfillment.
