High lead volume exposes a real gap in ERPNext CRM out of the box: the Lead DocType has no native scoring, and Assignment Rule gives you basic round-robin ToDo assignment but no concept of demographic fit, behavioral intent, score thresholds, or grade-based prioritization. Sales-ops teams end up bolting scoring logic into spreadsheets or leaving reps to cherry-pick leads, so hot inbound sits unworked while low-fit leads soak up capacity. When you try to encode "score the lead, grade it, then route hot A-grade leads to senior closers by territory" using only stock ERPNext configuration, you run out of road fast.

ECOSIRE builds a proper Frappe app — its own module, not a pile of loose customizations — that closes that gap. We add a Lead Scoring Rule DocType (weighted conditions on industry, company size, source, country, and any custom field you already capture) and a Lead Behavior Event model that accumulates points from tracked signals such as email opens, website visits, form submissions, or webhook pings via a whitelisted REST endpoint. A hooks.py doc event on Lead (and optionally CRM Lead on v16) recomputes the total score on validate/after_insert through a server script, writes back a numeric custom_lead_score and a derived grade (A/B/C/D against configurable thresholds), and stamps the scoring timestamp. Nothing is hard-coded — thresholds, weights, and grade bands live in a single Lead Scoring Settings singleton so your ops team tunes them without a redeploy.

Routing runs the moment a lead crosses a threshold. We ship a configurable Lead Routing Rule engine supporting three strategies: round-robin across an eligible sales pool, weighted round-robin (a senior rep can carry a 3:1 share), and territory/product-based assignment that maps the lead's territory, country, or product interest to a specific owner or team. Assignment writes a standard Frappe ToDo and sets lead_owner, so it plugs into the native Assignment Rule, notifications, and Kanban views you already use — reps see it in the same inbox, no new UI to learn. A scheduler event sweeps stale or unassigned hot leads on an interval as a safety net, and every scoring and routing decision is logged for audit. Client scripts surface the live score, grade, and next-best-action badge directly on the Lead form. Role profiles and permissions gate who can edit rules versus who only sees the outcome.

Because this is built for your ERPNext, it fits your fields, your territories, and your sales structure — and it targets the version you actually run (Frappe/ERPNext v15 or v16). It is not a Frappe Cloud Marketplace download; there is no instant install. After you request a quotation we run a short scoping call, confirm your scoring dimensions and routing strategy, then build, install on a staging bench, and hand over. Typical delivery is one working week from confirmed scope, and you receive the installable source, a git repository, documentation, training, and a post-go-live support window.
