HubSpot vs Custom CRM — The Real Bill After Year One
A custom CRM becomes cheaper than HubSpot Sales Hub Professional somewhere between month 12 and month 18 for a team of 10+ seats — the point where a one-time €9,000-€18,000 build crosses the accumulated €100/seat/month plus Marketing Hub and Operations Hub fees. This page compares HubSpot vs custom CRM without marketing fluff: feature parity, real 24-month TCO, when HubSpot wins, when custom wins. Numbers come from actual migration projects, not HubSpot's pricing page.
When HubSpot works and when it stops working
HubSpot is a good CRM up to a clear threshold — usually 5-10 seats, a simple sales process, no industry-specific logic. Past that line costs scale aggressively and the platform's constraints start forcing workflows that do not match how your business actually runs.
- ✓Sales Hub Starter €15/seat — fine under 5 users — basic pipeline, email templates, up to 1,000 contacts. Cross 1,000 marketing contacts and the bill jumps sharply.
- ✓Sales Hub Professional €100/seat — breaks at 10+ reps — a 15-person team is €1,500/month for Sales alone, before Marketing Hub (€800/month at 2,000 contacts) and Operations Hub (€720/month).
- ✓Custom objects capped at 10 types — if your business has 12-15 distinct objects (contracts, deliveries, sites, machines, inspections) you hit a hard ceiling and start cramming data into property bags.
- ✓Workflow automation lives in Operations Hub Pro €720+/month — SMS sends, complex branching, external-API enrichment all sit behind an extra subscription or require a third-party Zapier/Make layer.
- ✓Marketing Contacts pricing is the hidden bomb — past 5,000 marketing contacts adds €225/month, past 10,000 adds €450/month. Your cost grows with your list, not your revenue.
- ✓Export limits at churn — HubSpot lets you pull contacts and deals, but workflow logic, custom reports and activity history are lost on migration. Vendor lock-in is real.
Who custom HubSpot vs custom CRM is for
At 15 seats on Sales Hub Professional you pay €1,500/month, or €18,000/year for Sales alone. After 12-14 months a custom CRM development project with full feature parity has paid back and starts generating €15,000-€20,000/year in savings.
Construction firms, medical clinics, law practices, manufacturers — where the sales process has 8-15 stages, specific documents and integrations with ERP, inventory or machines. HubSpot forces you to simplify into its templates; custom software matches your process one to one.
When the CRM must generate compliant invoices, validate VAT numbers through VIES, sync to a company register and report to tax authorities — HubSpot needs three external integrations and still does not cover everything. A custom CRM does it natively, in one screen.
How we build a custom CRM with full HubSpot parity
A custom CRM is not "start from scratch for 18 months". We have a modular base — contacts, companies, deals, pipelines, tasks, email tracking, reports — that covers 80% of HubSpot functionality in the first sprint. The remaining 20% is the industry-specific logic HubSpot would never ship.
1. Audit current HubSpot and map features
We pull the list of actively used HubSpot objects, properties, workflows and reports. In 80% of cases the business uses 30-40% of paid features — the rest is "just in case". We map this to custom-CRM modules and identify the 3-5 workflows that drive 80% of value.
2. Architecture — PostgreSQL + Next.js + open-source stack
PostgreSQL for data, Next.js 15 for UI, Prisma for ORM, BullMQ for async jobs, Resend/Postmark for outbound email with tracking. The whole stack is open-source — no monthly platform fee, only hosting (€40-€120/month) and AI tokens if you embed an AI assistant inside the CRM.
3. Data migration from HubSpot
We extract contacts, companies, deals, notes, emails, calls and custom properties through the HubSpot Export API. Activity history is preserved — who wrote when, deal stage transitions, owner changes. No chronology lost. A business analyst on our side handles the pipeline-stage mapping, not you.
4. Workflows and automation without Operations Hub fees
We replicate every HubSpot workflow inside our own engine — emails, task creation, field updates, conditional branching. On top we add what HubSpot never ships natively: automatic offer and invoice generation, register sync, external-API enrichment through API integrations.
5. Reports, dashboards and BI layer
HubSpot reporting is locked inside the platform. A custom CRM writes to PostgreSQL — you can plug in Metabase, Grafana, Power BI or a custom dashboard and read directly. Cohort reports, win-rate by industry, deal cycle by rep — everything HubSpot requires Enterprise (€3,600/month) for is a SQL query here.
Why Saitami
The comparison is not "HubSpot is bad". HubSpot is a strong product for a specific profile. The real question is how much you pay for flexibility you do not use versus what it costs to own the process.

Frequently asked questions
What is the real 24-month HubSpot bill for 15 users?
Sales Hub Professional at 15 seats: €100 × 15 × 24 = €36,000. Add Marketing Hub Professional with 5,000 contacts: €800/month × 24 = €19,200. Operations Hub Professional for complex workflows: €720/month × 24 = €17,280. Year-one onboarding: €2,800. Total over 24 months: about €75,000. A custom CRM with migration and matching feature parity: €15,000-€22,000 one-time plus €40-€120/month hosting.
When does HubSpot win the comparison?
When your team is under 5 seats, your sales process is standard (lead → discovery → demo → close), you have no custom objects and no specific regulatory needs. At that configuration Sales Hub Starter at €75/month for 5 users is cheaper than any custom CRM for the first 3-4 years. HubSpot also wins when you intensively use Marketing Hub for nurture campaigns — replicating full email-marketing workflows takes meaningful extra build effort.
How long does a full migration from HubSpot to custom CRM take?
For a medium-complexity B2B business, 8-12 weeks. Weeks 1-2: audit and architecture. Weeks 3-6: base modules and data migration (contacts, companies, deals, notes, emails). Weeks 7-10: workflows, reports, email, phone and ERP integrations. Weeks 11-12: parallel run and cut-over. The old HubSpot stays read-only for 60 days so you can cross-check.
What happens to email tracking, sequences and call recording?
All replicated natively. Email tracking — open and click pixels through Postmark or Resend, every send lands as an event on the contact timeline. Sequences (multi-step email campaigns with branching) — a custom engine on top of BullMQ with full A/B control. Call recording — integration with CloudTalk, Aircall or Twilio Voice, the recording auto-attaches to the deal. In HubSpot these features need Sales Hub Professional minimum; in a custom CRM they ship with no seat fee.
Who supports the custom CRM after launch?
A standard support package — €280-€480/month — covers hosting monitoring, security updates, a 4-hour SLA in business hours and 8-hour SLA out of hours for critical incidents. Optional 24/7 SLA with 1-hour response at €680/month. For reference HubSpot Professional ships email support with 12-24h response; phone support sits only at the Enterprise tier (€3,600/month).
