Aritmos is a Sage Platinum Partner based in Lleida that has been implementing ERP solutions for commercial businesses since 1984. For shops and SMEs, it offers Sage 50 (invoicing, accounting, POS, stock). For wholesalers, chains and high-volume omnichannel operations, it implements Sage X3 with advanced warehouse management, complex pricing policies, e-commerce integration and EDI. It has also developed its own X3 vertical for the fashion and textile sector (Wear X3), which manages seasons, collections, sizes, colours, distribution to franchises and integrated POS.
Yes. Aritmos implements two solutions depending on the size of the business. Sage 50 is designed for small and medium-sized shops: invoicing, accounting, stock management and integrated POS. Sage X3 is for higher-volume operations: chains with multiple stores, wholesalers with thousands of SKUs, franchises with centralised distribution, and omnichannel operations with e-commerce and EDI integration.
Yes. By integrating the ERP with the e-commerce platform (WooCommerce, PrestaShop, Shopify), stock is synchronised in real time. A sale in the physical store reduces the stock shown online, and an online order updates the warehouse inventory. This prevents overselling and keeps availability up to date across all channels.
Yes. Aritmos has developed Wear X3, a vertical built on Sage X3 for the fashion and textile sector. It manages items by style, size, colour and fit. Purchase and sales orders with size-colour templates. Distribution to franchises and company-owned stores. Receipt of bundles. Picking and logistics with bundle and pallet documentation. Integrated POS with size and colour management. Stocktaking with imports from PDA terminals. Sales statistics by size and colour.
Yes. Sage integrates with Amazon and other marketplaces to centralise order management. Marketplace orders go straight into the ERP, are prepared from the same warehouse and invoiced with the same accounting. This avoids managing marketplaces as islands separate from the rest of the business.
Sage X3 has a flexible pricing engine: price lists by customer, group, channel and volume. Discounts by product family, periodic rebates and time-limited promotions. For fashion (Wear X3): prices by style with automatic generation of final items (style + colour + size), recommended retail price (RRP) and cost price per variant.
Aritmos offers both Sage 50 and Sage X3, so it can support a business from the SME stage to a high-volume chain without changing partner. It also has its own fashion vertical (Wear X3) with management of sizes, colours, seasons and franchise distribution, functionality that other partners do not offer natively.
It depends on the size (one store, a chain, a wholesaler), the sales channels (physical only or omnichannel), the number of users and the modules required. Sage 50 has a low entry cost for SMEs. Sage X3 is a larger investment for complex operations. Aritmos offers a free preliminary assessment. Get in touch for a demo.
