Client & Project Overview

The client is a mid-sized real estate builder based in the Delhi NCR region, with 2–3 active construction sites under operation.

Known for quality execution and timely handover of mid-rise residential and mixed-use commercial projects, the client was expanding operations while struggling to manage backend inefficiencies in procurement, stock movement, and vendor billing.

Each site operated with its own team of engineers, storekeepers, and purchase requisition handlers.

The Head Office controlled vendor onboarding, procurement, and payments but lacked real-time visibility and synchronization across departments.

The client sought a cost-effective ERP solution that could offer process discipline without disrupting field operations.

Challenges & Objectives

Core Challenges:

• Manual Material Requisitions (MRs) — They were using WhatsApp and spreadsheets that led to ad hoc purchases and duplicate orders.
• No real-time inventory tracking — site stores often raised fresh MRs despite central warehouse holding excess stock.
• Vendor billing was disjointed from actual deliveries. Bills arrived without reference to POs or GRNs, leading to frequent disputes and delayed payments.
• Site-wise budget tracking — This was impossible, making cost control reactive rather than proactive.
• Finance and procurement teams lacked integration — It was causing delays in invoice approvals and audit non-compliance.

Objectives:

• Digitize the complete Purchase → Inventory → Vendor Billing process across all active sites.
• Ensure real-time, site-wise inventory visibility and enable inter-site stock transfers.
• Implement a 3-way matching system: Purchase Order (PO) → Goods Receipt Note (GRN) → Vendor Bill.
• Minimize delays and manual dependencies through workflow-driven approvals.
• Keep implementation affordable, modular, and adaptable to future growth.

Scope of Work

Departments to be Covered:

• Central Procurement
• Site Engineers & Storekeepers
• Accounts Payable/Finance

ERP Modules Implemented:

• Odoo Purchase
• Odoo Inventory (Multi-Warehouse Setup)
• Odoo Invoicing & Vendor Billing

Key Processes Mapped:

• Site-wise Material Requisitions (MRs)
• RFQ to PO Generation and Approval
• Goods Receipt and Quality Checks
• Vendor Invoice Submission & Verification
• Multi-site Inventory Transfers
• Project Budget vs. Actual Purchase Reporting

Complexity Factors:

• Multiple active sites with decentralized operations
• Dynamic project timelines and material demand
• Custom workflows for approval matrices and vendor rating
• Integration of finance with operations

Solution Design & Implementation

To match the client’s construction-specific workflows, we customized Odoo’s native capabilities to fit real-world site processes:

Solution Highlights:

• Multi-warehouse structure was configured: HO Store, Site A Store, Site B Store — each with dedicated stock ledgers.
• Created a dynamic MR (Material Request) form accessible by site engineers, auto-linked to project codes and budget heads.
• Implemented workflow-based approvals: Site Engineer → Project Manager → Purchase Manager.
• Enabled RFQ and PO generation from approved MRs with automated vendor selection based on pricing and performance.
• Configured a 3-way matching rule engine: Invoices cannot be validated unless GRN is posted, and PO is confirmed. Quantity mismatches trigger alerts for manual verification.
• Added stock transfer logic to enable site-to-site or HO-to-site transfers, reducing excess procurement.
• Customized dashboards for: Pending MRs/POs Site-wise stock ledger Budget utilization per project Vendor invoice aging

What were the Execution Challenges?

Key Roadblocks:

• Change resistance from site teams who preferred informal procurement (calls, paper slips, WhatsApp orders).
• Difficulty in capturing accurate GRNs on time, especially when site engineers were unavailable.
• Initial confusion around invoice hold rules and mandatory fields in PO and GRN modules.
• Ensuring budget tracking aligned with finance ledger accounts required coordinated master data setup.

How We Resolved It:

• Conducted on-site role-based training for engineers, storekeepers, and finance staff.
• Deployed pre-configured GRN templates with dropdowns to reduce manual entry time.
• Built a lightweight mobile interface for field-level users to raise MRs and confirm GRNs on-site.
• Worked closely with client’s accountant to synchronize project codes and cost centers with ERP budget structures.

Results & Impact

Within 6 weeks of full deployment, the client reported significant operational gains:

Quantitative Results:

• 80% reduction in vendor invoice disputes due to automated PO-GRN-Bill validation.
• 50% faster purchase cycle — MR to PO to dispatch.
• 100% traceability of stock movement from HO to sites.
• 25% lower procurement cost variance due to better visibility and stock optimization.

Operational Improvements:

• Site teams now check available stock before raising MRs.
• Finance can approve or reject vendor bills in a click based on automated match status.
• Budget overruns are now proactively flagged, improving project profitability.

Strategic Benefits:

• Improved vendor relationships through predictable payments and dispute-free processing.
• Standardized, auditable process across projects — a major compliance win.
• Positioned for easy scale-up as new sites go live in the next financial year.

Client Feedback & Innovations

“Earlier, we had no control over how much was being bought, delivered, or paid — until it was too late. Now, we have complete visibility and control with minimal admin work. The Odoo solution is simple, effective, and fits our budget.”

— Director of Operations, Real Estate Builder, Delhi NCR

“We especially liked how the vendor rating and invoice hold logic was tailored for construction site dynamics. It has completely changed how we work with vendors.”
