The verdict in three sentences
A well-built CRM / marketing connector costs between GBP 9,000 and 28,000 in London in 2026, driven by the number of tools and the scoring complexity. The real payoff is not technical: it is +25% of leads actually worked and -30% leakage between the form and the sales rep. The monthly run stays low (GBP 150 to 500/month), making a one-quarter ROI realistic.
What drives the price of a CRM integration in 2026
Budget depends mostly on how many systems must sync, how fine the scoring and routing are, and the quality of your existing data. A simple form-to-CRM bridge is nothing like a multichannel scoring engine fed by web behaviour.
| Scope | 2026 price (GBP) | Timeline | Typical content |
|---|---|---|---|
| Simple form-to-CRM bridge | 9,000 - 13,000 | 3 weeks | 1 source, field mapping, basic dedup |
| Multi-tool connector | 13,000 - 20,000 | 4-5 weeks | CRM + email + forms, two-way sync |
| Advanced scoring and routing | 20,000 - 28,000 | 5-6 weeks | Lead scoring, sales routing, dashboards |
| Data cleanup + connector | 25,000 - 36,000 | 6-8 weeks | Base cleanup, governance, GDPR, training |
Recurring costs are often underestimated. A connector is a living thing: APIs change, volumes grow, new fields appear. A run budget is essential.
| Recurring item | 2026 range | Frequency |
|---|---|---|
| Connector maintenance | GBP 150 - 500/month | Monthly |
| Automation platform cost | GBP 50 - 220/month | Monthly |
| Integration day rate | GBP 550 - 900 | Per task |
| Quarterly scoring review | GBP 700 - 1,400 | Quarterly |
London vs Paris: 2026 order of magnitude
The same project costs noticeably more in the UK due to day rates and overheads. These are 2026 estimates for an equivalent scope.
| Item | London (GBP) | Paris (EUR ex. VAT) |
|---|---|---|
| Multi-tool connector + scoring | 9,000 - 28,000 | 9,000 - 20,000 |
| Integration day rate | 550 - 900 | 460 - 740 |
| Monthly run | 150 - 500 | 100 - 400 |
| Average timeline | 4-7 weeks | 3-6 weeks |
Mini case study
James, marketing director of a SaaS SME in London (45 staff), gets 800 leads/month through 4 forms and a monthly webinar. Without a connector, 30% of leads are never called back for lack of routing. He invests GBP 18,000 in a multi-tool connector with scoring, plus GBP 350/month run.
Calculation: recovering 30% of 800 leads (240 leads/month) at a 3% conversion rate and an average deal of GBP 2,000 yields roughly 7 won leads/month x GBP 2,000 = GBP 14,000 in additional monthly revenue. The upfront cost is absorbed in under two months, excluding the sales time saved (estimated at 15 hours/month).

FAQ
How long to connect my CRM to my marketing tools?
Expect 3 to 6 weeks in 2026 depending on the number of tools. A simple bridge ships in 3 weeks; a full scoring engine in 5 to 6 weeks.
Do I need to change CRM to add a connector?
No in 90% of cases. Common CRMs (HubSpot, Pipedrive, Salesforce, Zoho) expose sufficient APIs. A switch is only justified if the base is unmanageable.
What is the real maintenance cost?
GBP 150 to 500/month depending on volumes and number of APIs. Connectors break when a tool changes its API; maintenance covers those fixes.
Is lead scoring actually worth it?
Yes above 300 leads/month. Below that, simple routing suffices and avoids a GBP 6,000 to 9,000 surcharge.
Is it GDPR compliant?
Yes if consent is tracked and retention periods are defined. A compliance audit (GBP 800 to 2,000) is recommended before go-live.
