Case Study: Construction & Fit-Out Company, Abu Dhabi
How an Abu Dhabi fit-out contractor gained project cost visibility, eliminated billing disputes, and cut subcontractor payment time by 60% with Odoo.
Client Overview
An Abu Dhabi-based fit-out and interior construction company with annual project revenue of AED 28 million, running 8-12 concurrent projects across residential, commercial, and hospitality sectors. The company employs 45 office staff and manages 150-200 subcontracted workers depending on project load.
The company had grown significantly on the back of Abu Dhabis construction boom but had outgrown its project management approach — a combination of MS Project for scheduling, Excel for cost tracking, Tally for accounting, and WhatsApp for subcontractor communication. This patchwork worked at 3-4 concurrent projects but was breaking down at 8-12.
The Challenges
No Project Cost Visibility
Actual project costs tracked in separate Excel files per project. No centralised view of cost vs budget across all projects. Projects going over budget were discovered weeks after it happened.
Billing Disputes
Progress billing based on manual assessment without systematic milestone tracking. Clients disputed invoices regularly because they did not agree with the completion percentage claimed.
Subcontractor Management
Subcontractor payments processed manually from WhatsApp messages. No systematic tracking of subcontractor work orders, completion certificates, and payment history.
Retention Tracking
Retention amounts held by clients and owed to subcontractors tracked in spreadsheets. Retention release dates missed on both sides.
Material Procurement
Materials purchased project-by-project without visibility of common items across projects. No ability to consolidate purchasing for better supplier pricing.
Multi-Currency Projects
Some projects priced in AED, others in USD for international clients. Currency management in Tally was manual and error-prone.
The Odoo Solution
Rubicon implemented Odoo Project, Purchase, Accounting, and HR modules over 14 weeks, with custom configuration for construction-specific workflows including milestone billing, retention management, and subcontractor work order management.
Project Cost Management
Each project in Odoo has a detailed budget broken down by cost category: materials, subcontractors, labour, equipment, and overhead. All purchase orders and supplier invoices are coded to projects and cost categories. The project manager sees live budget vs actual for every cost category at any time — no waiting for month-end reports.
Milestone-Based Billing
Project milestones defined in Odoo with completion criteria and billing amounts. When a milestone is reached, the project manager marks it complete in Odoo, triggering the client invoice automatically. The invoice references the specific milestone completed — eliminating billing disputes because the criteria were agreed upfront.
Subcontractor Work Order System
Subcontractor work orders created in Odoo for each scope of work. Completion certificates raised in Odoo and approved by the project manager before payment is processed. Full audit trail from work order through completion to payment.
Retention Management
Retention amounts automatically withheld from subcontractor payments based on contract terms. Client retention tracked as a separate receivable. Odoo alerts when retention release dates approach — both amounts receivable from clients and amounts payable to subcontractors.

Key Learnings
Retention tracking is a hidden cash flow issue: Almost every construction company we work with has uncollected retention that has been forgotten or delayed. Odoos systematic retention tracking and automated alerts have recovered significant amounts for clients.
Milestone billing transforms client relationships: When billing criteria are defined and agreed at project start, disputes disappear. Clients know exactly what they will be billed for and when. Trust improves and payment cycles shorten.
Project cost visibility changes management behaviour: When project managers can see their budget vs actual in real time, they manage costs differently. Over-budget situations get addressed in week 3 rather than discovered in month 3.
