Tally is excellent for accounting but was never designed to run an online store. Odoo Ecommerce software combines a fully functional ecommerce website with inventory management, order processing, and GST billing, all integrated automatically. With Odoo online store, sales orders create invoices instantly, stock updates in real time, and payment reconciliations happen without manual data entry. Odoo Ecommerce features like product catalog management, customer portals, and marketing tools simply don’t exist in Tally. For online retail, Odoo gives you a complete business system while Tally leaves you managing the website separately.
