🏆 Official Odoo Partner | Certified Odoo Team | 50+ Odoo Implementations across Fashion, Real Estate, Textile, Travel, IT, and Manufacturing. I'm Kaushal Gajjar, Founder of 7Span - an Official Odoo Partner agency. I lead a certified Odoo team that delivers production-grade Odoo ERP implementations, customizations, and integrations for global businesses. We work across all Odoo versions, including the latest Odoo 19, and we know which version to put you on (and which to migrate you off of). What I deliver and what most "Odoo experts" miss: ✔ Odoo ERP Implementation (End-to-End): discovery, configuration, data migration, training, go-live, hypercare. Not just install-and-leave. ✔ Odoo Customization & Custom Module Development: Python/XML/OWL/JS, clean code that survives Odoo upgrades. No spaghetti. ✔ Odoo Migration & Version Upgrade: Odoo 13/14/15/16/17 → Odoo 18/19 with zero data loss and minimal downtime. ✔ Third-party Integrations: Shopify, WooCommerce, Amazon, Magento, Stripe, Razorpay, ShipStation, Salesforce, HubSpot, QuickBooks, custom REST APIs, EDI, and more. ✔ Odoo eCommerce, POS, Manufacturing (MRP), Inventory, Accounting, HR/Payroll, CRM, Sales, Purchase, Project, Helpdesk, Subscription, Field Service, Studio ✔ Odoo Functional Consulting & Business Process Mapping: for clients who need a roadmap before they need a developer. ✔ Performance Optimization, Bug Fixing, Server & Hosting Setup: Odoo.sh, AWS, DigitalOcean, on-premise. Why a Partner agency beats a solo freelancer: 🔹 Bandwidth: my certified team can run multiple workstreams in parallel. Backend dev, functional config, and UI/theme can move at the same time. 🔹 Coverage: sick days, time zones, and unexpected scope don't kill your timeline. 🔹 Accountability: you get a documented process, version-controlled code, staging environments, and proper QA, not "trust me, it works." 🔹 Officially backed: direct access to Odoo S.A. for licensing, enterprise support, and roadmap insights. Industries I've delivered Odoo for: Fashion & Apparel, Smart Luggage / D2C, Real Estate, Hotel & Hospitality, IT/SaaS, Manufacturing, Retail, eCommerce, Logistics, Professional Services. 🤝 My promise: if Odoo is wrong for your business, I'll tell you in the first call. If it's right, I'll show you the fastest, cleanest path to ROI. ☎️ Free 30-min Odoo audit Message me with your current setup or business workflow, and I'll send back a specific implementation/migration roadmap before you spend a dollar. Let's build a system that actually works for your business and grows with it.
