The TCO of a Custom-Built CRM vs. Salesforce Over 5 Years

'Custom-built is too expensive' — is that always true? A total cost of ownership analysis over 5 years to help you make an informed decision.

The argument against custom-built is usually the upfront cost: 'Salesforce is faster to deploy and cheaper to start.' That's true. But over 5 years, the picture is more nuanced. Here's a TCO analysis based on real projects.

Salesforce TCO (50 users, Sales + Service Cloud)

→Licenses: 50 users × $150/month × 12 months × 5 years = $450,000
→Initial implementation (certified partner): $60,000 – $150,000
→Annual enhancements and customization: $30,000 – $80,000/year
→Training and change management: $20,000 upfront + $10,000/year
→5-year total: $750,000 – $1,350,000

Custom-Built CRM TCO (NestJS/TypeScript, 50 users)

→Initial development (6–12 months): $150,000 – $350,000
→Cloud infrastructure (hosting, databases, CI/CD): $15,000/year
→Maintenance and enhancements: $60,000 – $100,000/year
→Training: $15,000 upfront + $5,000/year
→5-year total: $490,000 – $870,000

When Custom-Built Is Cheaper

→High user count: Salesforce licenses scale linearly; custom-built doesn't
→Highly specific needs: Salesforce customizations accumulate and get expensive
→Long-term horizon > 7 years: custom-built costs amortize, SaaS licenses don't
→Sensitive data: avoid Salesforce compliance and isolation surcharges

When Salesforce Remains Cheaper

→Team < 20 users: the custom-built break-even point is never reached
→Standard needs: why rebuild what Salesforce does perfectly
→No internal resources to maintain the code: technical debt explodes
→Need to launch in < 3 months: Salesforce is configurable; custom-built isn't

The Real Question

Beyond TCO, the real question is: does your competitive advantage live in your CRM logic? If yes, custom-built gives you total ownership that Salesforce can never offer. If not, pay the Salesforce licenses and focus your resources on your core business.
