Salesforce Web-to-Lead vs a Custom Integration: What UK Businesses Actually Need
When the free Salesforce Web-to-Lead form is enough, when you need a real integration, and how to tell the difference before you spend money.
If your website needs to talk to Salesforce, there are really only two questions that matter: is "a form that creates a Lead" enough, or do you need data to move both ways reliably? Get that right and you avoid both over-spending and a fragile setup.
When Web-to-Lead is genuinely enough
Salesforce's built-in Web-to-Lead (and Web-to-Case) is free, reliable, and correct for a large share of businesses. It's the right choice when:
- A website form should create a Lead (or Case) in Salesforce.
- You don't need the website to read anything back from Salesforce.
- Volume is normal and you don't need deduplication or instant processing.
If that's you, don't pay for an integration — generate a correct form with our free Salesforce Web-to-Lead & Web-to-Case Generator (correct endpoint, hidden fields, GDPR consent) and you're done.
When you've outgrown it
You need a real integration once any of these are true:
- Two-way sync — the site must show or use data that lives in Salesforce (pricing, account status, stock).
- Custom objects / Apex — your process isn't standard Leads/Cases.
- Deduplication & matching — you can't tolerate duplicate records.
- Real-time — downstream automation must fire immediately, not on a batch.
- Other systems — payments (Stripe), an ERP, or a portal need to share data with Salesforce.
These are engineering problems, not form problems — and doing them badly creates silent data loss that's expensive to unwind later.
How to size it before spending
Don't get a vague quote. Use the free Salesforce Integration Cost Calculator to model scope (objects, sync direction, volume, connected systems) and get an indicative UK range. It turns "how much?" into a structured conversation.
The pragmatic path most businesses should take
- Now: ship Web-to-Lead to capture enquiries immediately (free).
- When justified: build a scoped integration once volume or process complexity earns it — not before.
That sequence avoids paying for engineering you don't need yet, while never losing leads in the meantime.
