Field Service & Maintenance Contracts is a build-to-order Odoo module that ECOSIRE designs, develops, installs and supports for HVAC, elevator, IT/AMC, equipment-service and facilities companies. This is not an instant download from apps.odoo.com — it is a net-new module our Odoo engineers build to fit your service catalogue, SLA policies, technician rosters and invoicing rules, then deploy to your Odoo 17, 18 or 19 environment (Community or Enterprise) within a typical 2–4 week lead time.
Service contract records with coverage type, billing cycle, contract value and expiry, driven by computed fields (@api.depends) for auto-calculated renewal and next-service dates
SLA policy engine defining response and resolution targets per contract or priority, with SLA due-time computed on each work order and breach flags
Automated renewal reminders and preventive-maintenance work-order generation via scheduled actions (ir.cron) and server actions
One-click work-order creation from Helpdesk tickets or from a contract's PM schedule, preserving customer, equipment and contract linkage
Technician dispatch board with Gantt scheduling plus a map/route view to sequence site visits and spot SLA-at-risk jobs
Configurable on-site checklists (inspection steps, pass/fail, mandatory items) attached per service type so no step is skipped
At its core the module introduces custom models (built on models.Model) for service contracts, work orders, SLA policies and on-site checklists, wired into the customers you already have in res.partner and the products/spare parts in product.product. Contract value, coverage windows, next-service dates and SLA due timers are handled by computed fields using @api.depends, so renewal alerts and response-time deadlines stay accurate without manual bookkeeping. A work order can be spun up directly from a Helpdesk ticket or a contract's preventive-maintenance schedule, assigned to a technician, and tracked through a status flow (draft → dispatched → on-site → done → invoiced) that is enforced with proper state management.
Dispatch and scheduling are surfaced through Gantt and map/route views so a coordinator can see who is where, which jobs are at SLA risk, and how to sequence a route. Field technicians complete jobs from a mobile-friendly OWL/QWeb interface — running through the on-site checklist, recording parts consumed (which decrements stock and lines onto the job), capturing a customer signature, and generating a QWeb PDF service report on the spot. When labour and parts are confirmed, the job flows straight into account.move for on-site invoicing, or accrues against the contract for periodic billing.
Access is locked down with ir.model.access.csv and record rules so technicians only see their own assignments while dispatchers and managers get the full picture, and automated actions (server actions / scheduled crons) drive renewal reminders, SLA-breach escalations and preventive-maintenance generation. Everything is reachable over Odoo's XML-RPC / JSON-RPC API for integration with your existing tools. You receive clean, upgrade-safe source code — not a locked black box — plus documentation, training and a post-launch support window.
Runs a team of field techs servicing air-conditioning, refrigeration or industrial equipment under AMC contracts. Needs SLA tracking, preventive-maintenance scheduling and on-site invoicing so no contract lapses and every visit is billed.
Dispatches technicians across many buildings with strict response-time SLAs. Needs a map/route dispatch board, checklist-driven inspections and signed compliance reports for each site visit.
Sells annual maintenance contracts and break-fix visits. Wants tickets to convert straight into scheduled work orders, parts consumption tracked against inventory, and renewals flagged before they expire.
Assigns daily jobs and juggles emergencies. Needs a single scheduling view showing technician availability, job priority and SLA countdown to sequence work efficiently.

This is a build-to-order module, not an instant download. Typical lead time is 2–4 weeks from confirmed requirements, depending on how many contract types, SLA rules and checklist templates you need and whether we migrate existing data. We begin with a short scoping call, then share a working environment for you to review before we deploy to your production Odoo instance.
Every build includes a defined post-launch support and bug-fix window with a named contact. Because we hand over clean, upgrade-safe source, your team can extend it or we can maintain it under an ongoing support arrangement. We also provide compatibility fixes when you upgrade across Odoo 17, 18 and 19, and can add features (new SLA rules, report layouts, integrations) as scoped change requests.
It runs on both. We target Odoo 17, 18 or 19, Community or Enterprise. On Enterprise we can lean on native Field Service and Helpdesk where it makes sense; on Community we build the equivalent contract, dispatch and work-order logic into the module so you get the full workflow without an Enterprise licence.
Yes. Work-order completion uses a mobile-friendly OWL/QWeb interface so technicians can update job status, run checklists, log parts and time, capture a customer signature and generate the service report from a phone or tablet on site — including via the Odoo mobile app on Enterprise.
Yes. Confirmed labour and consumed parts turn into an Odoo invoice (account.move) directly from the work order for on-site billing, or accrue against the maintenance contract for periodic invoicing. Parts consumption is recorded as stock moves so your inventory stays accurate and each job carries its true cost for profitability reporting.
Yes. All models are accessible over Odoo's XML-RPC and JSON-RPC APIs, so the module can exchange data with an existing mobile app, customer portal, IoT sensors or third-party CRMs. We scope any specific integration up front and can build the connectors as part of the deliverable.
