Marketing runs in HubSpot; fulfilment, quoting, and invoicing run in ERPNext. When those two systems drift, your sales team re-keys deals into ERPNext by hand, contacts get duplicated, and nobody trusts the pipeline number in either tool. ERPNext ships a capable native CRM (Lead, Opportunity, Customer, Contact, Quotation DocTypes), but it has no first-party bridge to HubSpot — so once a deal is won in HubSpot, the handoff to a Quotation and Sales Order is manual, error-prone, and slow.

This connector closes that gap. ECOSIRE builds you a proper Frappe app — its own module, DocTypes, and hooks.py wiring — that performs configurable two-way sync between HubSpot's CRM objects and ERPNext. HubSpot contacts and companies map to ERPNext Contact/Customer (or Lead), and HubSpot deals map to Opportunity and, on the stage you nominate, to a Quotation with line items resolved against your ERPNext Item master. A HubSpot Settings single DocType holds the private-app token, portal id, and per-object field mappings, so property-to-fieldname mapping is configuration, not code you have to re-deploy.

Technically, real-time updates flow both directions. Inbound HubSpot webhooks land on a whitelisted Frappe method (@frappe.whitelist(allow_guest=True)) that verifies the X-HubSpot-Signature-v3 HMAC before enqueuing work via frappe.enqueue, so a burst of events never blocks a worker. Outbound changes are driven by hooks.py doc_events (on_update, after_insert) plus scheduler events for reconciliation sweeps that catch anything a webhook missed. Every call to the HubSpot v3 REST API is idempotent — we store the HubSpot object id on the ERPNext record and upsert, so re-runs and retries never create duplicates. Sync activity, payloads, and API errors are written to a HubSpot Sync Log DocType for auditing and replay.

Because it is a first-class Frappe app, it respects your existing controls: role profiles and permissions gate who can configure the integration, client scripts surface sync status and a "push to HubSpot" button on the Contact and Quotation forms, and marketing list membership syncs to HubSpot static lists so segmentation stays aligned. It is built and tested against Frappe/ERPNext v15 and v16, installed with bench get-app / bench install-app, and migrated with bench migrate.

Delivery is build-to-order — this is not an instant download. We start with a scoping call to confirm which objects, properties, and stages you sync and in which direction, then build against your field mapping, validate on a staging bench with your data, and cut over. Typical delivery is one working week from confirmed scope, and you receive the full source, a git repository handover, and a post-go-live support window.
