Business & Small Business
QuickBooks, Xero, Shopify, HubSpot and Salesforce package accounting, storefronts and CRM for small teams. Open source covers ERP, e-commerce, CRM, scheduling, e-sign and email marketing. This page lists our curated free picks, with official links.
Tax filing, payroll and local compliance still sit with your accountant or a certified service. Treat Odoo, Dolibarr and WooCommerce as management foundations — not a one-click substitute for every paid SaaS feature.
