Accounting firms run their clients' books beautifully but manage their own practice on spreadsheets, email threads, and memory. Odoo out of the box gives you strong accounting, timesheets, and invoicing, but it has no native concept of an "engagement," a filing deadline that repeats every quarter, a per-client compliance checklist, or a retainer that should trip a WIP alert when logged hours exceed the agreed fee. The stock account.move, project.task, and sale.order models were built for a company selling products or delivering one-off projects — not for a firm carrying dozens of clients through recurring bookkeeping, VAT/GST returns, payroll runs, year-end closes, and statutory filings, each on its own cadence with its own owner. That gap is exactly where partners lose margin and miss deadlines.

This is a build-to-order configuration package: ECOSIRE builds a firm-specific practice layer on top of Odoo and installs it for you. Technically, we ship a proper Odoo module — a __manifest__.py declaring dependencies on account, project, hr_timesheet, sale_management, and mail — rather than a pile of Studio tweaks that break on upgrade. We model your real objects: an engagement model (models.Model) linking a client res.partner to a service type, a fee basis (fixed, retainer, or hourly), a responsible partner, and a recurrence; compliance obligations carrying @api.depends computed next-due dates; and WIP/realization figures computed from account.analytic.line timesheets against the engagement fee. Recurrence and deadline reminders are driven by scheduled ir.cron jobs and base.automation rules, so a Q1 VAT engagement regenerates its task, assigns the owner, and posts a mail.activity reminder without anyone remembering to.

On top of the data model we build the surfaces your team actually uses: a partner dashboard and client-load kanban in OWL/XML views, a compliance-calendar list grouped by due date, QWeb PDF templates for engagement letters and monthly WIP statements, and access control via ir.model.access.csv plus record rules so a staff accountant sees only their assigned clients while partners see the whole book. Where you already push data from a tax portal, bank feed, or document-management tool, we wire it through Odoo's XML-RPC/JSON-RPC API rather than manual re-keying. Everything is scoped to your Odoo edition — Community or Enterprise — and targeted at your version, with support for Odoo 17.0, 18.0, and 19.0.

Delivery is build-to-order and starts with a short scoping call. We confirm your service catalog, deadline rules, fee structures, and roles, then write a fixed-scope statement of work, build on a staging database, run UAT with your team, and deploy behind a rollback plan. Typical delivery is 2–4 weeks from confirmed scope. There is no instant download — this is software we build, install, and support specifically for your firm. Pricing starts from $349 (indicative, single-company base scope); multi-company or multi-branch practice consolidation, deeper localization for statutory return types, and the volume of historical client data to migrate increase the quoted scope. You receive a fixed quote after the scoping call, never a surprise on the invoice.
