EPC Companies
Odoo Supply Chain for Solar connects procurement, inventory, vendor management, and site material tracking to your project BOM.
Solar EPC supply chains are not standard manufacturing. You procure against project BOMs For bigger projects, dispatch to active job sites, track serialised components for warranty, and manage vendor lead times across multiple installations simultaneously. Odoo manages all of it from one system.

Why Solar EPC Supply Chains Break
Running Procurement & Inventory on Disconnected Tools
At 5+ active projects, spreadsheets and WhatsApp groups cannot keep procurement, site stock, and vendor payments in sync.
📋
01
Procurement Runs on Memory
PO raised after the project is behind schedule. No link between BOM and purchase order. Lead time not in the plan.
📦
02
No Site-Level Stock View
Panels at site A, mounting at site B, inverters in the warehouse. Nobody has one picture of where material is.
💰
03
Vendor Bills Do Not Match
Bill says 500 panels. GRN says 480. The mismatch is found at quarter close, not at goods receipt.
BOM-Driven Procurement
How Odoo Connects Procurement to the Job Site
In Odoo Supply Chain for Solar, every purchase order is linked to the project BOM. Inventory demand is generated automatically after a sales order is confirmed. Procurement knows what to buy, for which project, and by when.
- ✓BOM-driven procurement — no manual PO creation
- ✓Vendor lead time tracked against project schedule
- ✓Dispatch to job site with serialised tracking
Procurement & Vendors
Purchase, Compare & Track Vendors
Odoo Supply Chain for Solar links every purchase to a project, BOM, and vendor. RFQs, pricelists, lead times, and 3-way matching are built into one workflow.
📋Purchase Order from BOM
Confirmed sales order generates purchase demand from the project BOM. RFQ sent to multiple vendors for comparison. POs created against approved vendors with agreed pricelists.
✓ Every PO tied to a project and a BOM.
👥Vendor Evaluation & Pricelists
Maintain vendor pricelists for panels, inverters, mounting, cables. Compare landed cost across vendors. Track delivery reliability and quality per supplier.
✓ Procurement decisions based on data, not relationships.
⏱️Lead Time Tracking
Every product carries a vendor-specific lead time. Odoo flags when procurement must start based on installation date minus lead time. Delays visible before they reach the site.
✓ Material reaches site when needed, not when someone remembers.
✅3-Way Matching & Landed Cost
Vendor bill validated against PO and goods receipt. Freight, customs, handling allocated to material cost. Advance payments adjusted on final bill. Real landed cost in the system.
✓ Accounts payable is clean. Real cost drives profitability.
Inventory & Site Material
Multi-Site Stock, Serial Tracking & Site Returns
Odoo Supply Chain for Solar tracks inventory across warehouses, depots, job sites, and transit with complete serial-level traceability. Odoo tracks every component at every location with serial-level traceability.
🏭Multi-Location Stock
Track stock across central warehouse, regional depots, and every active job site. Inter-location transfers with full audit trail. Real-time stock at every location.
✓ One accurate stock picture across all locations.
🔍Serial & Lot Tracking
Every panel and inverter tracked by serial number from receipt to installation. Lot tracking for cables and mounting. Warranty traceability from factory to rooftop.
✓ Warranty claims reference the exact serial number.
📤Site Issue & Site Return
Issue material to the installation crew against a picking list. Excess and damaged material returned to site stock or central warehouse after installation. Every movement recorded.
✓ No material vanishes between warehouse and rooftop.
🔄Reorder Rules & Forecasting
Minimum stock rules trigger automatic POs for fast-moving BOS. Demand forecasting based on confirmed pipeline and BOM explosion. Buffer stock without manual monitoring.
✓ Never discover a cable shortage the morning of installation.
Connected to Every Department
Supply Chain Integrated with Sales, Projects & Finance
Odoo supply chain is not a standalone module. It runs on the same database as your CRM, project management, and accounting — so every action flows through without middleware.
🔗Sales BOM Integration
When the CRM team confirms a solar deal, the BOM from the quotation triggers inventory demand and purchase requirements. Supply chain picks up exactly where sales left off.
✓ Procurement starts the moment the deal is signed.
📁Project App Link
Every purchase order and dispatch is linked to the project record. Project managers see material status without calling procurement. Delays in supply reflect on the project timeline automatically.
✓ Project managers see material status in real time.
🔀Alternate Product Handling
When a panel model or inverter is unavailable, Odoo suggests pre-configured alternate products with equivalent specifications. Substitution logged with approval trail for the project record.
✓ Supply shortage does not stall the project.
💰Finance & Costing Link
Vendor bills, landed costs, and material consumption feed directly into project costing and company accounting. Margin reports use real procurement cost, not estimates.
✓ Finance sees what supply chain spent — live, not monthly.
Mobile Warehouse
Manage Stock from the Job Site
Warehouse staff and site supervisors use the Odoo mobile app to receive goods, issue material, scan serial numbers, and process returns without returning to a desktop.
- ✓Goods receipt with barcode/serial scan
- ✓Site issue and return from mobile
- ✓Real-time stock synced across all locations

What Our Clients Say
Trusted by Solar & EPC Companies
We at Heaven Solar had the privilege of partnering with Tatvamasi Labs to develop and implement Odoo within our organization. From the start, their team demonstrated professionalism and expertise, understanding our specific needs and delivering beyond expectations.
Before the Odoo implementation, task and resource allocation were taking considerable time and often led to delays. However, after going live with the system, we saw a significant improvement in how we managed tasks and resources—everything became more streamlined and efficient.
Before the Odoo implementation, task and resource allocation were taking considerable time and often led to delays. However, after going live with the system, we saw a significant improvement in how we managed tasks and resources—everything became more streamlined and efficient.
We are truly grateful for Tatvamasi Lab's support and look forward to continuing our collaboration.
Before working with Tatvamasi Labs, our operations couldn't keep up with our ambitions. Leads from our energy calculators had to be manually entered into our sales system, follow-ups ran on scattered emails, and we had zero real-time visibility into our vendor network or field equipment. We were a fast-growing greentech startup held back by the fragile processes underneath.
Tatvamasi Labs changed that completely. They built a custom integration between our Airrange calculators and Odoo CRM, automated our entire sales pipeline, and gave us live tracking across projects, inventory, and warranties — all without adding headcount. Within the first quarter, our lead conversions rose by 27% and we doubled our operational capacity. It wasn't just an ERP implementation; it was the infrastructure our growth actually needed.
