E-commerce companies needing CRM should look at Firmao, which integrates invoicing with client management. If you need a modular ERP system (invoicing + KPiR + warehouse), choose Comarch ERP XT, where you only pay for the features you need.

Each of the listed programs is regularly updated in accordance with regulations (KSeF, JPK, VAT changes) and offers free trial versions. Before making a decision, it's worth testing several solutions in your business. When choosing, pay attention to the number of available users, warehouse support, bank integrations, payment systems, and types of technical support (helpdesk, accountant).
