The verdict in three sentences
A standard CRM connector (web form to HubSpot/Salesforce/Pipedrive) lands at 3,000 to 8,000 EUR in 2026, rising with advanced mapping, lead scoring and automations. Budget 50 to 300 EUR/month of run for connector hosting, monitoring and API quotas. The real gain isn't the price: it's zero lost leads and +20% pipeline conversion because every contact arrives qualified, timestamped and routed to the right rep.
What a CRM integration covers in 2026
In London, a CRM integration is more than "send the form into HubSpot". Three blocks stack up: capture and mapping (site fields to CRM fields), enrichment/scoring (heat score, deduplication, company enrichment), and orchestration (email sequences, sales notifications, task creation, territory routing).
| Integration block | 2026 scope | Price | Timeline |
|---|---|---|---|
| Standard connector | Web forms to CRM, simple mapping | 3,000 - 8,000 EUR | 2-3 wks |
| Mapping + scoring | Deduplication, lead scoring, enrichment | 2,000 - 6,000 EUR | 1-2 wks |
| Automations | Sequences, routing, notifications, tasks | 3,000 - 9,000 EUR | 2-3 wks |
| Reporting/attribution | Pipeline dashboards, sources, campaign ROI | 2,000 - 5,000 EUR | 1-2 wks |
| Monthly run | Connector hosting, monitoring, quotas | 50 - 300 EUR/mo | ongoing |
The CRM choice drives the bill. HubSpot exposes generous APIs and a flexible data model; Salesforce needs more configuration (objects, permissions, sandbox) so more person-days; Pipedrive is fastest to connect for an SME.
Costed scenarios by maturity
| Scenario | Typical stack | Project budget | Run/mo |
|---|---|---|---|
| SME start | Site + Pipedrive, simple connector | 3,500 - 5,000 EUR | 50 - 100 EUR |
| Growth | Site + HubSpot, scoring + 3 automations | 8,000 - 14,000 EUR | 120 - 250 EUR |
| Multi-team | Site + Salesforce, territory routing + attribution | 15,000 - 25,000 EUR | 250 - 300 EUR |
| Portability | iPaaS middleware + versioned connectors | +3,000 - 6,000 EUR | +40 - 80 EUR |
One watchpoint: API quotas and GDPR compliance (consent, legal basis, retention). A well-built connector logs failures and replays sends, otherwise a traffic spike can make leads vanish silently.

Sarah is head of sales at a B2B software vendor in London, 9 reps. Before integration, 15% of leads from forms were lost (manual re-entry, duplicates, oversights) out of 400 leads/month, i.e. 60 lost leads. With a 4% close rate and a 6,000 EUR average deal, that's 2.4 lost sales/month, or 14,400 EUR of revenue evaporating monthly.
She invests 12,000 EUR in a HubSpot connector with scoring and routing, plus 200 EUR/month of run. By recovering even half the lost leads and gaining +20% conversion on scored leads, the setup pays back in under two months. Over the year, run costs 2,400 EUR against more than 80,000 EUR of avoided shortfall.
FAQ
What's the cheapest CRM connector that actually holds up? Around 3,500 EUR for a site tied to Pipedrive with clean mapping and error logging. Below that you usually get an unmonitored webhook that loses leads in silence.
HubSpot or Salesforce, which costs more to integrate? Salesforce, typically 30 to 50% more in person-days due to configuration (objects, permissions, sandbox). HubSpot is faster for an SME under 20 reps.
How fast is it in production? A standard connector goes live in 2 to 3 weeks; with scoring and automations, expect 4 to 5 weeks including QA and load tests on the forms.
Is a 300 EUR/month run justified? Yes once you pass a few hundred leads/month: it covers monitoring, failure replay, API quotas and connector updates. One lost lead often costs more than a month of run.
Can we stay in control if we switch CRM? With an iPaaS middleware and versioned connectors, yes: cost rises 3,000 to 6,000 EUR but you avoid rebuilding everything during a CRM migration.
