If you run Google Ads lead-form campaigns, submissions usually land in a spreadsheet export or a fragile Zapier hop, disconnected from where the deal actually closes. ERPNext gives you a solid Lead and Opportunity pipeline, but out of the box it has no idea a contact came from a specific campaign, ad group, or keyword — and it has no path to tell Google Ads which of those leads eventually turned into revenue. So Smart Bidding keeps optimizing for raw form fills, not for the leads that become customers, and your cost-per-real-acquisition stays a guess. Native ERPNext has no Google Ads connector, no offline conversion upload, and no place to store gclid/campaign attribution.

ECOSIRE builds a proper Frappe app (its own module, DocTypes, and hooks.py) that closes this loop end to end. On the inbound side, we stand up a whitelisted webhook endpoint (@frappe.whitelist(allow_guest=True)) that receives Google Ads lead-form extension payloads — verified against your configured webhook key — and maps each field to a new Lead (or Opportunity) with a client-configurable field-mapping DocType, so you decide which lead-form question feeds which ERPNext field. The gclid, campaign, ad group, and keyword are persisted on the record for attribution, and a hooks.py after_insert doc event fires your assignment and routing rules (round-robin, territory, or owning sales team) using Frappe's native ToDo/assignment engine.

On the outbound side, a scheduler event walks recently won Opportunity/Quotation/Sales Order records that carry a stored gclid, builds the offline-conversion payload, and uploads it to the Google Ads API against your configured conversion action — reporting the real deal value and close date back to Google. Uploads are idempotent and logged in a dedicated Google Ads Conversion Log DocType so you can see exactly what was sent, retry failures, and reconcile against the Google Ads UI. OAuth credentials and the developer token are stored using Frappe's encrypted single/settings DocType, never in source. Everything respects ERPNext permissions and role profiles — marketing sees the sync dashboard, sales just sees their assigned leads.

Because this is a real Frappe app and not a no-code patch, it survives bench migrate, ships as an installable app you can version-control, and targets Frappe/ERPNext v15 and v16. Optional client scripts surface a "campaign source" section on the Lead form and a manual "resend conversion" button for edge cases.

This is a build-to-order engagement, not an off-the-shelf marketplace download. After a short scoping call we confirm your exact lead-form fields, conversion actions, and routing logic, then build, install on your staging bench for UAT, and hand over the git repository. Typical delivery is 2-4 weeks from confirmed scope, followed by a post-go-live support window. No instant download, no fabricated numbers — you get code built for your account and your ERPNext instance.
