Field Service & Maintenance Management

ECOSIRE builds a proper Frappe app installed into your existing ERPNext bench, not a fragile pile of customizations. At its core are custom DocTypes such as Service Request, Work Order (field-service, distinct from the manufacturing doc), AMC Contract, Service Checklist Template, and Spare Part Consumption, each with its own workflow states, role-scoped permissions, and naming series. A dispatch board built as a Frappe Desk page and List/Calendar view lets a coordinator assign technicians against their availability and skills; scheduler events registered in hooks.py handle the recurring work — generating preventive-maintenance visits from AMC schedules, firing SLA-breach warnings, and queuing renewal reminders before contracts lapse.

The technical wiring is designed to be maintainable by any Frappe developer. Document lifecycle logic lives in server-side controller methods and doc_events hooks (validate, on_submit, on_cancel) rather than scattered client hacks — for example, submitting a Work Order auto-creates the backing Stock Entry for consumed spare parts and posts the billable lines toward a Sales Invoice. Client Scripts drive the on-site experience: mobile-friendly checklist rendering, GPS/timestamp capture on check-in, and a signature pad that stores the customer sign-off as an attached file on the visit. Whitelisted methods exposed over the Frappe REST API let a technician mobile client (or your own PWA) fetch today's assigned jobs, update status, and submit completion offline-tolerantly. Role Profiles and permission rules keep dispatchers, technicians, and AMC managers each scoped to what they should see.

Because this is a Frappe app, it upgrades cleanly with your bench and coexists with the rest of ERPNext — Customer, Item, Serial No, Warehouse, and Sales Invoice all stay native, so accounting and inventory remain a single source of truth. We target ERPNext and Frappe v15 and v16, ship the app as a versioned git repository, and keep all logic in fixtures and code so nothing is trapped in a single site's database.

This is a build-to-order engagement, not a marketplace download. We start with a short scoping call to map your service workflow, contract types, and checklist requirements, then confirm scope in writing. Typical delivery is 2 to 4 weeks from confirmed scope. We build on a staging site, run UAT with your team against real scenarios, then install into your production bench with a rollback plan, hand over the git repository, and back it with a post-go-live support window.
