Custom CRM vs HubSpot vs Salesforce
Should a business build a custom CRM or pay for HubSpot or Salesforce?
The short answer
HubSpot or Salesforce wins for standard sales funnels with under five to ten users, where out-of-the-box templates launch instantly. A custom Next.js CRM wins when seat licenses exceed several hundred dollars a month, when workflows involve proprietary logic off-the-shelf tools cannot handle, or when data must remain strictly on private infrastructure.
Side by side
| Criterion | Custom CRM (Next.js & Postgres) | HubSpot / Salesforce |
|---|---|---|
| Recurring per-user license fees | $0 (self-hosted / single cloud hosting fee) | Hundreds of dollars per user / month |
| Workflow customization | Unlimited, built around your exact operations | Constrained to vendor object models |
| Data privacy & ownership | 100% owned by your company on your server | Held in third-party vendor cloud |
| Initial build cost | $5,000 – $20,000 one-time investment | Low initial setup, high compounding monthly fee |
| Integration with custom databases | Direct relational queries and API connectors | Requires expensive enterprise add-ons |
| Time to deploy | 4–8 weeks | Immediate to 2 weeks |
How to decide
Choose a Custom CRM when
- You have more than 10 users and subscription fees are scaling fast
- Your operational flow involves custom approval chains, unique pricing, or regional payment gateways
- You want complete ownership of source code and client databases without vendor lock-in
- You need deep integration with your custom website or internal ERP
Choose HubSpot / Salesforce when
- You have 1–3 sales reps and need a tool running by tomorrow
- Your sales process is standard B2B email tracking and pipeline stages
- You have zero budget for upfront software engineering
- You rely heavily on standard AppExchange plugins
What most comparisons leave out
The true cost calculation: 15 seats on HubSpot Professional costs around $15,000–$20,000 every single year. A custom Next.js CRM costs that once, never bills per user, and becomes an appreciating intellectual property asset on your balance sheet.
