Most transport and logistics operators end up running their fleet on spreadsheets bolted onto ERPNext: vehicle registration and insurance expiries in one sheet, fuel slips in another, a WhatsApp group for driver assignments, and maintenance that only gets scheduled after a breakdown. ERPNext core does not ship a fleet vertical — there is no native Vehicle lifecycle, no trip costing, no fuel-efficiency baseline, and no document-expiry alerting — so the moment you want to know real cost-per-kilometre or catch a lapsing road-worthiness certificate before it's illegal to drive, native runs out of road. The data lives outside the ERP, so it never reaches your accounting, purchase, or reporting.

ECOSIRE builds a proper Frappe app (its own module, installed alongside ERPNext, not a fragile customization) that models your fleet as first-class DocTypes. A Fleet Vehicle master holds registration, ownership, odometer, and a child table of documents (insurance, registration, fitness, permit) each with an expiry date; a scheduler event runs a daily job that queues expiry reminders to the responsible role before the deadline. Trip Log and Fuel Entry DocTypes capture route, distance, driver, and litres, with hooks.py doc events computing mileage and cost-per-km on submit and rolling those figures into report-ready fields. Preventive maintenance is driven by either odometer thresholds or calendar intervals, generating Maintenance Schedule tasks and linking the resulting work to ERPNext Purchase and Stock so parts and vendor bills stay in your books.

Everything is wired into ERPNext's own primitives so it behaves like part of the system, not a plugin sitting beside it. Drivers, roles, and license tracking use Frappe's permission model and role profiles; client scripts add odometer validation and in-form warnings; server scripts and whitelisted methods expose trip and fuel data over the Frappe REST API for your telematics feed, mobile capture, or BI tool. Because it's a real app with a git repository, it upgrades cleanly across ERPNext versions and you own the source.

Build-to-order means we start from your actual operation, not a generic template. A short scoping call establishes your vehicle types, the documents you're legally required to track, how trips are costed, and which roles do what. We build against that scope, deliver on a staging site for UAT, then install on your production instance with a rollback plan. Typical delivery is one working week from confirmed scope. You receive the installable source, documentation, a training session, and a post-go-live support window — and the git repo, so nothing is locked to us.
