A bill sent on WhatsApp to the family whose Saturday box is collected by a neighbour, so the one who collects can see what the box held and what was charged.
Orders to suppliers
An order to a farmer or a farmers' group from your phone, with its date and what you asked for, so the season's lots can be matched to what you owe.
Your own online shop
A page listing the millets, pressed oils and jaggery you hold today with their rates, so a family can check before it makes the trip.
Offers for regular customers
For the family that has bought one farm's rice for many months, a discount on that rice only, with the farm's name on the same bill line.
Low stock warnings
A warning when a flour sack runs low, so you order a fresh small lot instead of topping up the old one.

The farm districts that feed a Tamil Nadu organic shelf
Organic goods come from the farm districts, and a few Tamil Nadu districts show what is grown there.
- Viluppuram is called the sugar bowl of Tamil Nadu, and its sugarcane supplies all the cane for 7 sugar mills in the district, which makes jaggery a natural thing to ask for from there.
- In Salem, the Malgoa mango is the pride of the district, and tapioca, grown widely and used mainly to make starch, is another major crop.
- Chennai's Koyambedu Wholesale Market Complex has 3,194 shops for perishables on 295 acres, and an organic shop in the city sets its fresh prices against what that yard charges.


A late harvest, traditional rice in sacks that look alike and a weekly box nobody wrote down
A late harvest and a bare millet sack
After a dry spell a farmer's millet harvest comes a month late, and the shop has no millet in the very weeks the festival buyers arrive. You tell each customer the same story, they go away, and some do not come back.
Traditional rice in sacks that look alike
Mapillai samba, karuppu kavuni and seeraga samba sit in sacks that look much alike, and their rates differ a good deal from one kind to the next. The scoop moves from one sack to another, the chalk label rubs off, and a customer is charged for the dearer rice while the cheaper one is scooped. At the month's end the stock of each kind does not match what its sack holds.
The weekly box that lives on a customer's word
A family takes the same box every Saturday: a kilo of millet, a bottle of oil, some greens. The shop remembers the order, until the person who remembers is away, and then the box is wrong or not packed.

Questions Tamil Nadu organic store owners ask about farmers, oils and boxes
The weekly box holds millets one month and pulses the next. Is it the same item?
Name the month's contents in the box's item, millet box or pulse box, so the count of each box stays true and the daily report shows which box the families took.
Customers ask whether the rice is this year's harvest or last year's. Where do I write it?
Write the harvest year in the rice's item, for example mapillai samba, this year's harvest. The old sack and the new sack then have their own counts, and the bill tells the customer which she bought.
Karuppu kavuni, mapillai samba and seeraga samba sacks look alike. How do I keep them apart?
Make each rice its own item, named in full. The sack's count then falls under the right name when the bill is made, even when the three sacks stand side by side.
Organic farming in Tamil Nadu: a policy and a Chennai market
In March 2023 Tamil Nadu unveiled an Organic Farming Policy to support chemical-free farming and supply safe food. The shops that sell what such farms grow are the ones who have to show where it came from.
In January 2024 a state agriculture department market at Semmozhi Poonga, Chennai, was reported to sell specially grown vegetables bought directly from farmers. A private organic shop in the same city has to give its customers a reason to choose it over that market.
