Marketing agencies run on a mix of monthly retainers, fixed-scope projects and ad-spend pass-throughs, but Odoo core has no native concept of an agency retainer that draws down against tracked hours, no unified view of campaign profitability across timesheets, media spend and vendor invoices, and no structured creative-approval loop for client sign-off. Teams end up bolting the real work onto spreadsheets: which retainer hour bucket a task consumed, whether a campaign is over-servicing, what markup applies to reseller ad spend, and where a deliverable sits between draft, internal review and client approval. project.task, sale.order and account.move all exist, but nothing ties them into the agency operating model out of the box — and a generic off-the-shelf apps.odoo.com module inevitably assumes a workflow that isn't yours.

This is a build-to-order package: ECOSIRE designs and builds a custom Odoo module set for your agency, then installs and supports it. Technically it centers on new models such as agency.retainer and agency.retainer.line (compute fields with @api.depends roll up consumed vs. contracted hours from account.analytic.line/timesheets, surfacing burn-down and over-service alerts), extends project.project and sale.order with campaign and media-budget fields, and adds a crm.stage-style creative approval workflow on deliverables driven by base.automation automated actions and mail.activity for client reminders. Retainer renewal and invoicing are handled by scheduled ir.cron jobs that generate the next account.move draft; markup on pass-through ad spend is computed at the analytic line. Every model ships with proper ir.model.access.csv grants and ir.rule record rules so account managers see only their clients, plus OWL/XML views, list/kanban/pivot dashboards for utilization and margin, and QWeb PDF reports for client-facing retainer statements.

Everything integrates with what you already run — Sales, CRM, Project, Timesheets, Accounting and, on Enterprise, the timesheet-to-invoice and dashboard layers — rather than replacing them, and where you're on Community we implement equivalent flows without leaning on Enterprise-only widgets. Data flows in and out over the standard XML-RPC/JSON-RPC API so your reporting tools, ad-platform connectors or a headless client portal can read live campaign and retainer state. We build against your target series and confirm compatibility for Odoo 17.0, 18.0 or 19.0.

Delivery is build-to-order and structured: it starts with a scoping call to pin down your retainer types, approval stages, markup rules and integrations, after which you receive a fixed written quote and timeline. Typical delivery is one working week from confirmed scope, depending on integration count and data migration. You get the installable source for your version, deployment on a staging environment for UAT, and a post-go-live support window. Pricing starts from $999 (indicative, single-company base scope); multi-company agency networks, deeper ad-platform and finance integrations, localization of tax/invoicing rules, and larger historical data migration increase the quoted scope.
