Primaseller vs Erplain Comparison: Everything You Need to Know Before Choosing

Erplain is a cloud-based inventory and order management application designed to simplify B2B sales and stock control for small businesses. Developed in France and used internationally, it targets wholesalers, distributors, manufacturers and brands that sell to other businesses and need more than basic spreadsheets, but do not want the complexity or cost of a full enterprise resource planning system. Erplain brings inventory, sales orders, purchasing, invoicing and customer management into a single, user-friendly interface, with the aim of making it faster, easier and more profitable to run a small business. Its focus on B2B workflows distinguishes it from inventory tools built primarily for retail or e-commerce sellers. Inventory management tracks stock levels across multiple warehouses, with support for product variants, bundles and kits, and automatically updates quantities as orders are shipped or goods received. Sales functionality includes quotes, sales orders, delivery notes, invoices and credit notes, with customer-specific price lists and discounts, and payment tracking. Purchasing features cover purchase orders, supplier management and receiving, with low stock alerts to support timely reordering. A B2B ordering portal allows wholesale customers to browse catalogues and place orders online, reducing manual order entry. Integrations with e-commerce platforms such as Shopify and WooCommerce synchronise inventory and orders across channels, while connections to accounting software such as QuickBooks and Xero streamline financial processes. Reporting provides insight into sales performance, stock value and margins. The mobile-friendly interface and cloud delivery make the application accessible from anywhere without infrastructure management, and the system is designed to be set up quickly with minimal training. Erplain is aimed at small wholesale and distribution businesses, craft producers, food and beverage suppliers and brands selling to retailers. Pricing starts from around USD 34, with a free trial available; there is no permanently free version.
