StackPlus ERP
A lightweight web ERP for wholesale distributors with multi-unit products, batch and expiry tracking, receivables and payables control, and simple profit reporting in one system.
Stock variance below 2% and 20%+ more receivables collected on time
Live DemoThe Problem
Distributors and wholesalers deal with more complexity than regular retail: multi-level units (1 Dus = 12 Pack = 144 Pcs), tiered customer pricing, credit terms with customers and suppliers, and products with expiry dates and batch numbers. Most still use paper books or Excel, so receivables become overdue, expired goods go unnoticed, real profit margin is unclear because purchase cost keeps changing, and physical stock rarely matches system records.
Our Solution
GrosirPro is a micro ERP built only around the modules wholesale businesses actually need. It supports multi-unit products with automatic conversion, per-warehouse stock with batch and expiry tracking (FEFO), sales with receivables control, and purchasing with payables tracking. Stock is always stored in the base unit to avoid rounding errors, and HPP is calculated with a moving average. The data model is multi-warehouse ready from day one, so a business can start with one warehouse and add more without migration.
