The verdict in three sentences
Wiring your B2B website forms into Salesforce is a 6,000-20,000 EUR project in 2026, easily worth it if your sales team still re-keys leads by hand. The choice is between a native API connector (reliable, bidirectional, deduplicated) and a no-code tool like Zapier/Make (fast, but fragile at volume and complex mapping). As soon as you want scoring, bidirectional sync and serious deduplication, the native API wins.
Native API vs no-code: where the limit is
Zapier or Make connect a form to Salesforce in a day for a few hundred euros a year. But they cap out quickly: approximate duplicate handling, no fine business logic, costs that explode at volume. A custom connector costs more to build but becomes an asset.
| Criterion | No-code (Zapier/Make) | Custom native API |
|---|---|---|
| Upfront cost | 500-2,500 EUR | 6,000-20,000 EUR |
| Recurring cost | 240-1,800 EUR/year | 1,200-3,600 EUR/year |
| Timeline | 2-5 days | 4-8 weeks |
| Deduplication | Basic | Advanced (business rules) |
| Bidirectional sync | Limited | Full |
| Lead scoring | No | Yes |
| Volume handling | < 500 leads/month | Unlimited |
What creates value: mapping, dedup, scoring
The technical wiring is the easy part. Value comes from the quality of the data injected into Salesforce and the speed of sales follow-up.
| Function | Impact | Effort |
|---|---|---|
| Form → Salesforce object mapping | Removes re-keying | Low |
| Lead/Contact/Account dedup | Avoids polluted duplicates | Medium |
| Automatic scoring (industry, size, page) | Prioritises callbacks | Medium |
| Bidirectional status sync | Aligns marketing/sales | High |
| UTM/source attribution | Measures campaign ROI | Low |

Sophie, marketing director of a B2B SaaS vendor in Manchester, generates 320 leads/month via her site. Before, an SDR spent about 6 h/week re-keying and deduplicating in Salesforce. Native API connector quote: 11,500 EUR, plus 2,400 EUR/year maintenance. Gain: ~6 h/week recovered (~15,000 EUR/year) and callback time cut from 9 h to under 30 min. Measured effect (2026 estimate): lead-to-opportunity conversion +22%. Payback: under 9 months.
FAQ
Is Zapier enough to start? Yes, under 500 leads/month and with no complex business logic. Beyond that, per-task costs and dedup limits make the native API cheaper from year one.
Is bidirectional sync useful? Very, if marketing needs to see the real status (opportunity won/lost) to adjust campaigns. Otherwise an upstream sync (site → Salesforce) is enough and costs 30-40% less.
How do we avoid duplicates in Salesforce? Through matching rules on email, domain and company name, applied before creation. It is the item that best protects the value of your sales database.
How long to deliver? Between 4 and 8 weeks for a native connector, depending on the number of forms, scoring complexity and access to your Salesforce org.
Can leads be scored automatically? Yes: industry, company size, pages viewed and source are combined into a score that prioritises follow-up, measurably faster than manual triage.
