A leaf ledger that shows small tea growers what their leaf really earned
TL;DR Leafledger is a shared ledger for small tea growers and the bought-leaf factories they sell to. Each delivery of green leaf is weighed, recorded and later matched with the price the factory's tea fetched. Tea brands that claim fair sourcing pay for the proof, and growers see their own records free.
Small growers now produce about half of India's tea. In 2021 they made 688.82 million kg of the country's 1,343.06 million kg[1]. Most sell fresh green leaf to bought-leaf factories, often through agents, and get paid a per-kg rate on the spot. What the factory later earns for the finished tea is a separate number the grower rarely sees.
And that number swings a lot. The Tea Board's district averages for bought-leaf factory tea in July 2024 ranged from ₹103.67 a kg in the Nilgiris to ₹264.08 in Jorhat[2]. If a grower can't connect his leaf to those prices, how is he supposed to tell a fair rate from a poor one? He can't, and the brand buying the tea can't either.
Leafledger records each leaf delivery at the factory gate - grower, weight, quality deductions and rate paid. The factory clerk enters it and the grower confirms it on a basic phone, in Assamese, Bengali, Tamil or Malayalam. Each month the ledger lines those entries up with the factory's own sale prices for the tea made, and with the Tea Board's district average[2]. Growers see what share of the finished price reached them. Factories see their leaf cost per kg of made tea. Brands get a supplier report showing grower payments against sale prices, lot by lot.
I reframed the seed, which pitched blockchain traceability for fair trade. A blockchain keeps only what someone types into it, and an honest record has to start at the weighbridge and the payment slip. An ordinary database with grower confirmation and an audit trail does that job more cheaply. The seed's goal stays the same, which is making it visible whether the trade was fair.
Growers use it free. The payer is the tea brand or exporter that already funds sustainability work and needs proof for its own customers - the biggest packaged-tea companies fund the industry's sustainability code, for example[3]. Bought-leaf factories pay a smaller fee if the ledger replaces their paper leaf registers. I found no public price for supplier-payment reporting, so the kit sets test prices.
The industry code reports that 74% of Indian tea, 1,011 million kg, was verified under its code in 2025[3], so brands already pay for sourcing proof. Its farm-diary app, used by 31 companies in 2022, carries records from farm to factory gate[3]. And the Tea Board publishes district averages for bought-leaf factory prices month by month[2], which hands growers a public yardstick.
There's no public figure for spending on supplier-payment transparency in tea. The narrowest firm numbers are small growers' 688.82 million kg in 2021[1] and brand-funded verification already covering most of India's crop[3]. Fairtrade's model of paying a premium on top of the price[4] shows buyers will pay for fairness claims, though its pages give no India volumes.
The industry code runs verification and farm-diary apps, which 20,000 small growers were using by 2022[3]. Its public material centres on farm practices and traceability up to the factory gate. Fairtrade certifies producer groups and adds a premium on top of the selling price[4]. The Tea Board publishes the averages but can't show any single grower his own share[2]. Leafledger's gap is the payment record linking one grower's leaf to one factory's sale price.

The ledger itself is simple software. The hard part is persuading bought-leaf factories to show growers their sale prices at all, since many will see it as giving away margin. You need a brand willing to make it a buying condition, and field staff who can sign up growers and agents in one district.
No special licence while the ledger only records payments. The baseline still applies, plus a few rules about tea data.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI decide whether a price was fair or accuse a factory of underpaying. Those judgements need a person who has checked the records.

Here's what can go south -
Best if you know the tea trade in Assam, north Bengal or the Nilgiris and can sit across from factory owners. If you want to sell a traceability platform for every crop then this isn't the one. Prove first that one brand will make the ledger a buying condition and that two factories will share sale prices for three months.
Plan for roughly ₹45–90 L, mostly field staff to sign up growers and factories, plus the software. The ledger itself is cheap to build.
Not while you only record payments. You need company registration, GST, DPDP compliance for grower data, and data fields that match Tea Board returns.
Yes, wherever smallholders sell raw leaf or produce to processors, as in coffee or cocoa. Check local data protection law and how the industry board reports prices.
