If you sell on IndiaMART, every inquiry that lands in your seller Lead Manager but never reaches ERPNext is a follow-up that happens late or never happens at all. Most Indian manufacturers and traders end up copy-pasting buyer names, phone numbers, and product interest from the IndiaMART panel into ERPNext by hand — or worse, working leads out of WhatsApp and a spreadsheet while their ERPNext CRM stays half-empty. ERPNext ships a capable Lead DocType, assignment rules, and a Sales pipeline, but it has no native connector to the IndiaMART Push/Pull Lead API, no scheduled ingestion, and no de-duplication logic tuned to how the same buyer re-inquires across multiple products. That gap is exactly where response time — the single biggest driver of B2B conversion — quietly leaks away.

We build a dedicated Frappe app (its own module, installed on your bench with bench get-app / bench install-app) that closes that gap. A settings DocType holds your IndiaMART CRM API key, glusr credentials, sync window, and default owner, encrypted as a Password field. A Frappe scheduler_events hook (hourly or at your chosen cadence, plus an on-demand "Sync Now" button via a whitelisted method) calls the IndiaMART pull-lead endpoint, normalizes each inquiry, and creates or updates a Lead — carrying buyer name, mobile, email, city/state, the IndiaMART query text, and the specific product enquired into standard and custom fields. Every record is stamped with the source IndiaMART query id so the same enquiry is never imported twice.

De-duplication runs on a configurable key — mobile number and/or email, with fuzzy handling for the +91/leading-zero variants IndiaMART returns — so a buyer who pings you about three products becomes one Lead with a threaded activity trail, not three orphan records. Product-interest mapping links the enquired product string to your ERPNext Item (or a lookup table you approve during scoping), so sales sees exactly what the buyer wants. Auto-assignment applies your rules — round-robin across a sales team, or territory/product-based routing using ERPNext Assignment Rules and ToDo — and can fire a notification so the owner acts within minutes. Everything is built on supported extension points: hooks.py doc events, server scripts, optional client scripts for the "Sync Now" UX, role-based permissions, and the Frappe REST API — no core patches — so it upgrades cleanly on Frappe/ERPNext v15 and v16.

Because this is build-to-order, we start with a short scoping call to confirm your IndiaMART API access, field mapping, dedupe key, and assignment logic, then build against your real (or a sandbox) inquiry payload. You get the installable app source for your version, deployment on your bench, UAT on a staging site with a rollback plan, and a handover of the git repository — not a black box. Typical delivery is one working week from confirmed scope, and you own the code.
