Losing $692K to Budget Overruns? Track Odoo 18 Project Budgets

Project manager: "Website redesign project done!" CFO: "What was final cost?" Manager: "Uh... let me check invoices..." 45 minutes later: "$127,400." CFO: "Budget was $50,000. You're $77,400 over!" Manager: "I didn't know we had a budget." Why? No budget tracking in Odoo. Expenses tracked separately from budget. Nobody watching spend in real-time. Result: Project 255% over budget. Client won't pay overages. Company eats $77,400 loss.

Your project budget nightmare: 23 active projects. Zero budget tracking configured. Project A budgeted $50K, actually spent $127K (nobody noticed until invoices tallied). Project B: Forgot to bill customer $23,400 in expenses (not tracked to project). Project C: Vendor overcharged $8,700, approved payment because no budget comparison. Annual result: 47% of projects over budget, average overage $32,100 = $347,700 total losses. CFO: "Why can't we see project profitability in real-time?"

Cost: 47% projects over budget × $32,100 average × 23 projects = $347,700 annual overage losses. Unbilled expenses discovered late: $23,400 × 8 projects = $187,200 revenue never recovered. Manual budget tracking in spreadsheets: 8.7 hours weekly × $65/hour × 52 = $29,380 wasted. Budget vs actual comparison quarterly (not real-time): Discover overages after too late to fix = $127,400 average loss per major overrun. No visibility into profitability until project closed = can't course-correct mid-project.

Odoo 18 Project Budgets fix this: Link budgets directly to projects via analytic accounts, real-time tracking (see budget vs actual instantly), separate revenue and expense budgets, automatic allocation when invoices/bills posted, project dashboard shows allocated/spent/remaining, percentage-based alerts (90% budget consumed = warning). Here's how to configure project budgets so you stop losing $691,680/year to untracked spending.
