Independent hotels, resorts and guesthouses usually run the property on one system and the business on another: a third-party PMS for the front desk, a separate tool for housekeeping, spreadsheets for the night audit, and ERPNext (or QuickBooks) somewhere downstream for the books. Rates get keyed twice, folio charges never quite reconcile against the general ledger, and nobody trusts the daily revenue number because it lives in three places. ERPNext core is genuinely excellent at Sales Invoices, Payment Entries and inventory, but it has no concept of a reservation, a room-night, a folio, a housekeeping status or a night-audit close — so out of the box it simply cannot run a front desk.

This product closes that gap. ECOSIRE builds a proper Frappe app (its own module, installed via bench get-app and bench install-app) that adds the missing hospitality layer directly inside your ERPNext site. We model the domain as first-class DocTypes — Room, Room Type, Rate Plan, Reservation, Folio, Folio Charge and Housekeeping Task — with the naming series, links and child tables a hotel actually needs. Reservations flow through a state machine (Tentative, Confirmed, Checked In, Checked Out, No-Show) enforced by a Frappe Workflow, and role profiles (Front Desk, Housekeeping, Night Auditor, Manager) scope who can see and do what through ERPNext's permission engine and User Permissions.

Technically, the logic lives where Frappe wants it. Availability and rate resolution run in whitelisted server methods (@frappe.whitelist()) so the reservation calendar and the check-in screen call the same source of truth. hooks.py doc events (on_submit, validate, on_update) keep the folio honest: posting a charge writes a Folio Charge row and, at check-out, the folio is materialised into a standard ERPNext Sales Invoice and Payment Entry — so revenue hits the real general ledger with no re-keying. Client scripts drive the tape-chart calendar and the housekeeping board; a scheduler event (scheduler_events in hooks.py) runs the night audit to roll the business date, post room-and-tax charges for in-house guests, flag no-shows and freeze the day's numbers into a daily revenue report. Everything is reachable over the Frappe REST API, so a booking-engine or channel-manager integration is a clean follow-on rather than a rebuild.

Because this is build-to-order, nothing is shipped as a generic download. After you request a quotation we run a short scoping call, agree the exact room types, rate logic, tax treatment and reports you need, and fix the scope in writing. We then build against Frappe/ERPNext v15/v16, deliver to a staging site for your UAT, and only go live once you sign off — typically one working week from confirmed scope depending on complexity. You receive the full source code for your version, a git repository handover, install and configuration on your environment, technical and user documentation, a training session, and a post-go-live support window. It is your app on your ERPNext, not a black box.
