Car wash and detailing centers live and die by throughput at the bay. A center running plain Odoo quickly hits the wall: Sales and POS can sell a "Premium Wash" as a product, but there is no concept of a physical bay, a time slot, or a queue; a customer's vehicle is just free text on an order line, so nobody can pull up "last time this SUV was here we used the clay bar and it needed a headlight restoration"; and recurring unlimited wash plans have no engine to authorize a member's daily visit or stop a lapsed card getting a free wash. Teams end up running the actual operation on a whiteboard and a spreadsheet while Odoo only sees the money after the fact — which means no capacity planning, no membership margin visibility, and no service history.

ECOSIRE builds a dedicated Odoo module that closes that gap. We add first-class models for bays/wash lines (carwash.bay), appointments (carwash.appointment linked to res.partner, a fleet.vehicle or a lightweight carwash.vehicle profile, and the chosen carwash.package), and memberships (carwash.membership driven by a product.pricelist, a billing cadence, and an entitlement counter). Service packages are configurable products with an add-on detailing menu (ceramic coating, engine bay, pet-hair removal, headlight restoration) so an order is assembled fast at the counter or a self-service kiosk. Every appointment carries a state machine (draft → scheduled → in_bay → done → invoiced) with @api.depends computed durations and an estimated finish, so the queue display and the bay calendar stay honest.

Technically it is a clean addon: a proper __manifest__.py declaring dependencies on base, sale_management, point_of_sale, calendar, and optionally fleet; models in models/ using models.Model with typed fields, @api.depends/@api.constrains for slot-overlap prevention and entitlement checks, and SQL constraints so two appointments can never own the same bay-slot. Access control ships as ir.model.access.csv plus record rules that scope data by branch/company for multi-location operators. The UI is Odoo views (list/form/calendar/kanban/gantt where the edition allows, with an OWL queue-display widget), automated actions and scheduled crons drive recurring membership billing and no-show handling, and QWeb reports produce the branded service receipt and a monthly membership-revenue statement. POS integration adds the package and add-on menu to the POS screen and validates membership entitlement at the point of sale; the whole thing is reachable over Odoo's XML-RPC/JSON-RPC API for kiosks, license-plate cameras, or a mobile check-in app.

Because it is build-to-order, we scope it to your reality first: your bay count and opening hours, your exact package/add-on menu and pricing, whether memberships are unlimited or credit-based, single-site or multi-branch, and Community vs Enterprise (calendar/gantt and studio-style niceties differ — we build to whichever edition you run, targeting Odoo 17.0, 18.0, or 19.0). After a short scoping call we confirm the spec in writing, build on staging, run UAT with your data, then install on your instance. Typical delivery is one working week from confirmed scope. You receive the full installable source and the git repository — there is no lock-in, and you or any Odoo partner can extend it later.
