Residential institutions run their hostels on a patchwork of spreadsheets and paper registers: one file tracks who lives in which bed, another tracks mess plans, a third chases rent and deposits, and none of them agree. Wardens cannot see live vacancy, the finance office reconciles hostel dues by hand, and parents have no visibility into where their child is allocated or what they owe. Odoo out of the box has no concept of a hostel, a block, a bed, or a mess plan — account can raise an invoice and contacts can hold a student record, but nothing models the physical residence hierarchy, the allotment workflow, or the recurring rent-plus-mess-plus-deposit billing that a warden's office actually runs on.

This is a build-to-order module that ECOSIRE designs and writes for your institution on top of base, mail, and account. We model the full residence hierarchy as dedicated ORM models — hostel.block, hostel.floor, hostel.room (carrying a room type and a capacity), and hostel.bed — so occupancy is tracked at the individual bed level, not just the room. Live occupancy and vacancy figures are compute fields with @api.depends on the active allotments, so the occupancy dashboard and vacancy report always reflect reality instead of a stale export. The allotment record moves through a state machine (draft → waiting → allotted → vacated) with a waiting-list queue, a room-change action that releases the old bed and claims the new one atomically, and a vacate/checkout step that computes the refundable deposit balance.

On the money side we integrate directly with Odoo's native account.move rather than reinventing invoicing: hostel-fee billing composes rent, mess charges and a security deposit into invoice lines against a configurable set of income and deposit-liability accounts, so hostel revenue flows into the same ledger, tax and aged-receivable reports the finance team already uses. Mess and meal-plan setup drive per-resident meal attendance, and a warden can raise complaint or maintenance tickets against a specific room or bed, threaded through mail.thread so every note and status change is logged in the chatter. Access is locked down with ir.model.access.csv plus record rules so a warden sees only their assigned block while the residence administrator sees the whole estate, and an optional per-room asset inventory tracks furniture and fittings against each room. A parent-facing view (exposed over the JSON-RPC/XML-RPC API for an existing portal, or as a QWeb-rendered statement) surfaces the resident's allocation and outstanding hostel dues. QWeb reports cover the allotment letter, fee statement and vacancy register, and automated actions can nudge the waiting list or flag overdue dues.

Because this is build-to-order, nothing ships as an instant download — we start with a scoping call, agree the exact hierarchy, fee structure and workflows in writing, then build, test on a staging copy of your database, and deploy for Odoo 17.0, 18.0 or 19.0 (Community or Enterprise). Typical delivery is one working week from confirmed scope. Pricing starts from $999 (indicative, single-company base scope); multi-company estates, integration with an existing student-information or fee module, deeper localization of deposit/tax accounting, and the volume of legacy occupancy data to migrate all increase the quoted scope.
