Built for Enterprise Precision

A modular PostgreSQL engine designed to eliminate operational silos across all tiers of your organization.

Multi-Tenant Enterprise Hierarchy

Hierarchical single-database isolation. Single SSO login at Organization level with granular independent company, branch, and warehouse role scopes.

POS Shift Boundary Lock

Dynamic temporary cashier accounts. When a shift ends, automated double-entry journal vouchers empty suspense accounts straight into main corporate ledgers.

Double-Entry Chart of Accounts

Comprehensive sub-ledger posting rules, auto-balancing journal vouchers, trial balances, P&L generation, and multi-currency fiscal year controls.

Warehouse & PDT Operations

Real-time stock movement tracking, picking lists, delivery notes, physical inventory counts, and handheld PDT terminal barcode scanning integration.

ZATCA Phase 2 E-Invoicing

Native XML generation, cryptographic stamp creation, UUID hashing, and automated API integration with regional tax authorities.

Automated Spring Boot & Kotlin Sync

Engineered with Kotlin Spring Boot backend services, JPA transactional boundaries, multi-tenant connection pools, and Compose Desktop clients.

Industrial-Grade Database Architecture

Unlike bloated dynamic ORMs, DOWQO ERP utilizes a lean, 107-table relational schema designed for sub-millisecond execution and linear scalability.
