Open Source ERP and CRM System: Own Your Data for 95% Less
Salesforce costs $195+ per user per month. Twenty CRM costs $9. The gap is not a typo. It is your chance to own your customer data, escape vendor lock-in, and scale without per-seat pricing traps.
Why Open-Source ERP/CRM Over Proprietary Platforms
The shift from per-user SaaS to open-source ownership is not just about price. It is about control, flexibility, and cost predictability.
Cost Control
Salesforce Pro Suite is $100/user/month billed annually. A 10-person team pays $1,200/month or $14,400/year just to track deals. Twenty CRM: $90/month flat or $9/user/month. At 100 users, you pay $900/month, not $19,500.
Data Ownership
With Salesforce or HubSpot, your customer data lives on their servers under their terms. With open-source CRM on Opsily, your data stays on EU servers you control. No surprise migrations. No negotiated data exports if you leave.
Modern, Developer-First Platform
Twenty CRM is built on modern tech: React frontend, NestJS backend, PostgreSQL database, GraphQL API. Not a 20-year-old architecture with legacy UI. It integrates with n8n, Zapier, and your own custom workflows. Your engineers can extend it.
Built for teams who need reliability
What is Open-Source ERP/CRM?
Enterprise Resource Planning (ERP) systems manage inventory, accounting, and operations across your business. Customer Relationship Management (CRM) systems track leads, contacts, deals, and interactions.
Proprietary ERP/CRM platforms like Salesforce, HubSpot, and SAP own your data, charge per-user, and lock you into their ecosystem.
Open-source ERP/CRM systems (Odoo, ERPNext, Dolibarr, Twenty CRM) are code you can audit, modify, and self-host. You decide where data lives, who accesses it, and how much you pay.
Why the Shift Is Happening Now
Google's 2026 AI Overview lists Odoo, ERPNext, and Dolibarr as top open-source platforms. But it does not mention Twenty CRM. That gap matters: Twenty is the modern, developer-first option built for teams that need CRM now and might add workflows, custom objects, or integrations later.
Teams are asking: "Does ERP include CRM?" (yes, some do) and "Is there a free, open-source option?" (yes, many).
But the real question is this: Why rent customer data access at $100+/user/month when you can own it for $9 or less?
Hidden Costs Proprietary Platforms Don't Tell You About
Google's AI Overview calls out this problem: open-source ERP/CRM have "hidden costs" (hosting, security, IT team). That is true if you self-host on your own VPS. Opsily solves this: managed hosting, daily backups, security updates, 99.9% uptime, all for a flat fee that does not scale with headcount.
Result: you get open-source ownership at managed-platform prices.
Open-Source ERP/CRM vs Proprietary Pricing
Real-world cost comparison for a 10-person sales team over 12 months.
Salesforce Pro Suite pricing from official site. Twenty Cloud pricing from twenty.com. Opsily managed hosting on top of Twenty Pro plan.
Saved per year on a 10-person sales team
Compared to Salesforce Pro Suite ($195/user/month). That is capital to reinvest in marketing, support, or product. Not SaaS fees.
