Distributors and carriers running ERPNext hit a wall the moment shipping stops being a single field on a Delivery Note. ERPNext core gives you Delivery Trip and a driver link, but it has no concept of consolidating multiple sales orders into one truckload, no rate card that compares a contracted carrier against your own fleet, no freight accrual that lands in the general ledger before the carrier invoice arrives, and no structured proof-of-delivery trail with milestone timestamps. Planners end up in spreadsheets, dispatchers phone drivers, and finance reconciles freight weeks late — while the shipment data that should live in ERPNext leaks out to email and WhatsApp.

The ECOSIRE Transportation Management System is a proper Frappe application (its own installable app, not a pile of customizations) that adds a transport layer directly on top of ERPNext. We model the domain as first-class DocTypes — Load Plan, Trip/Dispatch, Carrier Rate Card, Freight Cost Entry, and Proof of Delivery — each with workflow states, role-scoped permissions via Role Profiles, and naming series that fit your operation. Load planning consolidates open Delivery Notes and Sales Orders by lane, weight, and volume onto a truck; a Kanban-style dispatch board assigns driver and vehicle and moves trips through Draft → Planned → In Transit → Delivered → Settled. Rate management holds distance/weight/zone-based tariffs for both external carriers and owned vehicles, so the planner sees a true cost comparison before committing a load.

Technically, the app is wired the ERPNext way. hooks.py doc events (on_submit, on_update, validate) drive automation — submitting a trip books a freight accrual Journal Entry against a configurable expense/accrual account and reconciles it on carrier settlement, so freight always hits the GL in the right period. Scheduler events run nightly to flag overdue-in-transit trips and stale PODs. Server scripts enforce capacity and rate-lookup logic; client scripts add the in-form dispatch actions and validations planners actually use. Everything is exposed over the standard Frappe REST API plus purpose-built @frappe.whitelist() methods, so a driver mobile app or a customer portal can post milestone updates and POD photos without bypassing permissions. We build against ERPNext/Frappe v15 and forward-test on v16.

Because this is build-to-order, nothing ships until we agree on scope. It starts with a scoping call where we map your lanes, fleet, carrier contracts, and how freight should post to your chart of accounts. We then build your version of the app, deliver it on a staging bench for UAT against your real data, and only cut over to production once you sign off. Typical delivery is one working week from confirmed scope, depending on how many rate structures and integrations are in play. You receive the full source in a Git repository — this is your app, not a locked black box, and it runs inside your own ERPNext instance.
