Most teams that run ERPNext also live in Google Workspace all day — sales reps reply from Gmail, project managers schedule in Google Calendar, and finance drops proposals into Drive. ERPNext ships an Email Account (IMAP/SMTP) integration and a basic Google Calendar sync, but the seams show fast: emails land in a mailbox that is only loosely tied to the right Lead or Sales Order, calendar sync is one-directional and brittle around recurring events, attachments bloat the site's own filesystem and backups, and every user still maintains a separate ERPNext password. The result is duplicate data entry, "which system is the source of truth?" arguments, and a CRM that nobody trusts because the real conversation happened in an inbox ERPNext never saw.

The ERPNext Google Workspace Suite is a proper Frappe app (its own module, DocTypes, and hooks.py) that closes those gaps. For Gmail, we implement a 2-way sync that pulls threads via the Gmail API and writes them as Communication records linked to the correct reference DocType (Lead, Opportunity, Customer, Issue), and pushes replies composed in ERPNext back out through Gmail so the sent copy appears in the user's real Sent folder. A scheduler event (scheduler_events in hooks.py) polls incrementally using Gmail history IDs so we never re-import the same message, and doc_events on Communication fire the outbound push. Calendar sync is genuinely bidirectional: an ERPNext Event created or updated fires a document event that upserts the matching Google Calendar event (with attendees and reminders), while a webhook-backed whitelisted method ingests changes made on the Google side. Drive support adds a storage backend so File attachments can live in a chosen Drive folder — the File DocType stores the Drive file ID and a signed link instead of a local blob, keeping your site database and backups lean. Google SSO is implemented via Frappe's Social Login / OAuth so users sign in with their Workspace identity, with domain restriction and mapping to ERPNext role profiles.

Under the hood everything is built the Frappe-native way so your team can own it: OAuth credentials and per-user tokens are stored in dedicated DocTypes with encrypted fields, token refresh runs on a scheduler event, all Google calls go through whitelisted server methods (never raw client-side secrets), and connection status plus sync logs are exposed as a DocType you can filter and audit. Client scripts add the in-form actions (Sync Now, Attach from Drive, Connect Google Account); permissions and role profiles gate who can connect an account and who can see synced Communications. The REST API surface is preserved, so any of the sync methods can also be driven headlessly. The app targets Frappe/ERPNext v15 and v16 and is written to survive bench migrate cleanly.

Because this is build-to-order, ECOSIRE builds it around your actual setup rather than shipping a generic binary. We start with a short scoping call to confirm which Google services you need, your Workspace admin constraints (OAuth verification, domain-wide delegation vs per-user consent), and which ERPNext DocTypes the sync should touch. Typical delivery is one working week from confirmed scope. You get the full installable source for your version, installation and configuration on your bench, UAT on a staging site with a documented rollback plan, a training session, and a post-go-live support window — plus handover of the git repository so the app is yours to keep and extend.
