Project Cash Flow Forecasting and S-Curve Modeling

1. Overview & Business Value#

This comprehensive operational guide details the architecture, business workflows, configuration parameters, and execution steps for Project Cash Flow Forecasting and S-Curve Modeling within SmartERP.

Generating project S-Curves, matching IPC billing milestones against vendor and labor commitments, and overdraft planning.

2. Prerequisites & Security Access Groups#

• Required Modules: project, smarterp_project_governance, hr_timesheet
• Security Groups:
  • Project User (Technical ID: project.group_project_user)
  • Project Administrator (Technical ID: project.group_project_manager)
  • Timesheet Approver (Technical ID: hr_timesheet.group_hr_timesheet_approver)
• Master Data Dependencies: Project master records, milestone stages, work breakdown structures (WBS), bill of quantities (BoQ), and employee billing cost rates.

3. Step-by-Step Configuration & Execution#

Step 1: Navigating to the Module Interface#

1. Log into your SmartERP instance at https://smarterp.et/odoo.
2. Open the main App Switcher (grid icon in the top-left corner).
3. Select the Projects app icon.
4. From the top navigation bar, open Projects → Dashboard → My Tasks / All Projects; Timesheets → Timesheets.

Step 2: Creating and Parameterizing Records#

1. Click the New button in the top-left control panel.
2. Complete the mandatory fields in the record form:
   • Project / Task Name (Mandatory): Descriptive title of work package or milestone deliverable
   • Assigned Project Team (Mandatory): Lead project manager and operational contributors
   • Planned Dates (Mandatory): Scheduled commencement and milestone completion deadlines
   • Customer / Stakeholder (Mandatory): Client partner linked to project contract and invoicing terms
3. Configure optional operational parameters and localized tags as required:
   • Analytic Cost Center (Optional): Dedicated project accounting account for expenditure tracking
   • Bill of Quantities (BoQ) Line (Optional): Specific contractual BoQ item code for construction tracking
   • Milestone Billing Weight (Optional): Percentage of contract value tied to milestone acceptance
4. Click the Save icon in the control bar to commit the record.

Step 3: Validating and Processing Transactions#

• State Transitions: Execute operational state progression (New / Scoping → In Progress → Review / Testing → Completed → Archived).
• Ledger & System Impact: Timesheet confirmations and project purchases post direct expenditures to the project analytic account, enabling real-time cost vs. revenue margin analysis.
• Audit Verification: Automated recording of author ID, timestamp, and immutable revision history.

Construction Cash Flow Dynamics#

Cash flow timing is the leading cause of contractor insolvency in Ethiopia. Advance payments must be preserved for major procurement (rebar coils, tower cranes, imported electromechanical packages) while monthly IPC disbursements must fund ongoing local labor and materials.

Procedure: Generating an S-Curve#

1. Navigate to Projects > Planning > Cash Flow & S-Curve.
2. Select your construction project.
3. The system pulls planned BoQ milestone dates from the Gantt schedule.
4. SmartERP plots:
   • Baseline Planned Value (PV) S-Curve: Theoretical cumulative expenditure.
   • Actual Cost of Work Performed (ACWP): Real-time debits from purchase bills, payroll timesheets, and store SIVs.
   • Earned Value (EVWP): Certified IPC valuation to date.
5. Review the Monthly Cash Inflow vs Outflow Projection table to anticipate funding shortfalls and negotiate bank overdraft credit lines in advance.

4. Advanced Configuration Points#

• Automated Actions & Scheduled Tasks (Crons):
  • Project: Flag overdue milestone deadlines (project.ir_cron_overdue_tasks): Runs daily to notify project managers of pending schedule delays
  • Timesheets: Send unsubmitted reminder alerts (hr_timesheet.ir_cron_timesheet_reminder): Runs weekly on Friday afternoon to remind team members
• Custom Print Templates & Reports:
  • Project Status & Milestone Execution Scorecard
  • Interim Payment Certificate (IPC) for Construction
  • Project Timesheet & Resource Utilization Summary
  • Earned Value Management (EVM) Financial Report
• Multi-Company Rules: Record-level security isolation under Company 1 (Ashewa Technology Solutions S.C.), preventing cross-company ledger leakage across parent and subsidiary legal entities.
