Open-Source Tools for Building a Transparent Supply Chain

The Problem with Hidden Supply Chains

Let’s say you order a beautiful cotton kurta online. It looks great, feels soft, and the price is just right. But do you know where the cotton came from? Who stitched it? Was the worker paid fairly?

Most businesses don’t have clear answers. The supply chain is often a maze—manufacturers, middlemen, logistics providers—each adding their own layer of secrecy. Customers want transparency. Governments are tightening regulations. And companies that fail to track their supply chain properly risk bad press, lawsuits, or worse—loss of trust.

Good news? You don’t need expensive software to fix this. Many open-source supply chain tools make transparency affordable, practical, and easy to implement.


1. Track Every Raw Material with OpenTimestamps

Let’s start with the basics: proving when and where something happened. OpenTimestamps does exactly that. It uses Bitcoin’s blockchain to create tamper-proof timestamps for any document, including invoices, shipping logs, and product origins.

How it works:

  • You upload a document (e.g., a supplier invoice).
  • OpenTimestamps creates a unique timestamp and records it on the blockchain.
  • Later, anyone can verify when that document was created—proving that your materials came from the right source at the right time.

Who’s using it?

A tea exporter in Assam started using OpenTimestamps to log purchase details from small farmers. This stopped fraud in its tracks—no more fake invoices or middlemen marking up prices unfairly.


2. SourceEth: Verify Supplier Ethics in Real Time

Sourcing materials ethically is tricky. A supplier might promise fair wages and sustainable practices, but how do you verify that?

Enter SourceEth, an open-source tool that integrates with Ethereum’s blockchain. Suppliers upload compliance documents, worker payment proofs, and environmental impact reports. Buyers can cross-check these records in real-time—no blind trust needed.

Best part? It creates smart contracts between businesses and suppliers. Payments only go through if ethical standards are met.


3. Odoo: Open-Source ERP with Supply Chain Transparency

Many businesses already use Odoo, an open-source ERP (Enterprise Resource Planning) tool. What most don’t realise is that it can be customised for full supply chain visibility.

How it helps:

  • Track products from factory to warehouse to customer.
  • Automate supplier approvals with built-in compliance checks.
  • Generate audit trails for every transaction.

A Bengaluru-based organic spice brand integrated Odoo with QR codes on its packaging. Customers could scan a code to see where the spices were grown, who harvested them, and when they were processed. Sales jumped by 40% in just a few months—customers loved knowing they were getting genuine, ethically sourced products.


4. Snipe-IT: No More “Lost” Inventory

Ever had stock disappear without explanation? Maybe it’s theft, maybe it’s bad record-keeping. Either way, you need a better system.

Snipe-IT is an open-source asset management tool that helps businesses track inventory in real time.

What makes it special?

  • Every item gets a unique ID with location tracking.
  • Employees can check in/check out assets digitally.
  • All movements are logged, so missing stock is easy to trace.

One electronics importer in Mumbai used Snipe-IT to track high-value components. The result? They cut losses by 30% within a year, simply by knowing exactly where their goods were at all times.


5. Hyperledger Sawtooth: Build a Custom Blockchain for Your Supply Chain

If you want full control over your supply chain data, Hyperledger Sawtooth is a game-changer. Unlike public blockchains, it lets businesses create private, secure chains that track every transaction.

How businesses use it:

  • A seafood company in Kerala uses Sawtooth to record catch locations. This prevents illegal fishing and ensures restaurants only get legally sourced seafood.
  • A pharma distributor tracks medicines from manufacturer to pharmacy, preventing counterfeit drugs from entering the supply chain.

Hyperledger Sawtooth might sound complex, but it’s actually quite flexible. Businesses can start small—tracking just one part of their supply chain—and expand later.


6. Freight Trust: No More Hidden Shipping Costs

Shipping invoices are often a nightmare. Hidden fees, delayed payments, and lost documents make logistics messy. Freight Trust fixes this with an open-source digital ledger for freight documentation.

Why it’s better than traditional shipping software?

  • Bills of lading, customs documents, and invoices are stored securely on a blockchain.
  • Payments are automated—no more waiting weeks for approvals.
  • Shippers and buyers get real-time visibility on costs and delivery status.

For exporters dealing with overseas shipments, this tool is a lifesaver.


7. Ushahidi: Crowdsource Supply Chain Issues

Sometimes, supply chain problems come from the ground level—farmers not getting paid, factory workers protesting poor conditions, or truckers facing unfair treatment.

Ushahidi is an open-source platform that collects reports from people on the ground. Businesses can use it to track ethical violations, fraud, or supply disruptions in real-time.

A garment manufacturer in Tamil Nadu set up an Ushahidi system where workers could report unsafe conditions anonymously. Management used the data to fix problem areas, avoiding legal trouble and improving worker satisfaction.


8. Graphite Docs: Secure Supplier Collaboration

Emailing suppliers back and forth is slow, and traditional document-sharing tools come with security risks. Graphite Docs is an open-source, encrypted alternative to Google Docs, perfect for collaborating on supply chain contracts and agreements.

Key features:

  • Documents are encrypted end-to-end.
  • Only approved users can view or edit files.
  • Changes are logged, preventing data tampering.

For businesses dealing with sensitive supplier agreements, this is a smart alternative to commercial document-sharing services.


Why Open-Source?

Big companies spend millions on supply chain software. Open-source tools give small and mid-sized businesses the same power without the heavy price tag. Plus, open-source software is:

Transparent – No hidden code, no data tracking behind your back.
Customisable – Modify it to fit your exact needs.
Community-driven – Developers constantly improve these tools.


Where Do You Start?

If your supply chain is a black hole right now, don’t panic. Start small. Pick one area to improve—maybe tracking invoices, securing supplier data, or verifying shipments. Once you have that under control, expand further.
