Cold Storage Rent Calculation and Lot Register: How To

A cold store sells space and time. Each lot occupies a place in a chamber for a number of days and the farmer pays for that. When the lot register is accurate and the rent rule is written down, the rest of the year is calm. When either is vague, every withdrawal turns into a negotiation. This guide sets out a process for the register and for rent, which you can adapt to your own tariff.

Step one: receive and number the lot

At the gate, record the farmer's name, phone, address or ward, produce type, number of bags and weight, the date and the vehicle. Give a lot number that is unique across seasons, for example with the Nepali year as a prefix. Record who received the produce and who weighed it. A lot with no named receiver is a lot nobody is responsible for.

• Check the quality at intake. Rejected or damaged bags should be noted, not hidden.
• Record the bag size or unit conversion you use, so quintals and bags can be compared.
• Print two copies of the receipt: one for the farmer and one for the store file.

Step two: allocate the chamber

Assign each lot to a chamber, floor or rack position as your layout allows. Keep a simple map. When a farmer later asks for twenty bags of a lot, the store keeper should know where to look without moving everything. Record any move between chambers with date and reason.

Step three: define the rent rule in writing

Write the rule once and display it. A typical rule has these elements:

1. The unit: per bag, per quintal or per kilogram.
2. The basic period: a season, a month or a fixed number of days.
3. Rate changes: whether the rate changes after a certain date or length of storage.
4. The minimum charge: some stores apply a minimum period or amount.
5. Advance and deposit: any money paid at intake and how it is adjusted.
6. Late charges: what happens if produce stays beyond the agreed date.

Rates and rules differ between stores and years, so use your own. This article does not quote any rate. If your cold store is part of an association, check whether it recommends common terms.

Step four: handle partial withdrawals

Farmers rarely take everything at once. A lot may be released in three or four parts as market prices change. For each release, calculate rent from the intake date to that release date for the quantity released. Keep the remaining balance on the lot with the original start date. The register should show, for each lot, the quantity in, the quantity out by date and the balance.

Give the farmer a release slip each time, showing the lot number, quantity released, rent charged, payment received and quantity still in store. Ask the farmer to sign or acknowledge. Keep the signed copy.

Step five: the final statement

When the last part of a lot leaves, print a lot statement: total in, each release with date and rent, total rent, advances adjusted, payments made and balance. If the farmer has more than one lot, offer a combined farmer statement. A farmer who sees all releases and charges on one page seldom disputes.

Weekly reconciliation

• Total physical bags counted in each chamber against the register balance.
• Rent due by lot and by farmer, sorted by oldest first.
• Lots approaching the end of their agreed period.
• Any lots without a recent contact with the farmer.

Physical counts need not be daily, but they should be regular, and a variance must be investigated the same week.

Dealing with spoilage and shrinkage

Produce can lose weight or quality in storage. Decide in advance who bears what: your terms might say that the store is not liable for natural shrinkage, or have a limit for it. Record any spoilage you notice with the date and photo if you can, and tell the farmer. Cold chain failures from power cuts should be logged with the dates and duration. Legal liability is a matter for your agreements and advisers; the register just needs to show the facts.

Lost receipts and duplicate claims

Farmers lose receipts, and sometimes more than one person claims the same lot, especially when a family splits or a trader has bought the produce from the farmer while it is in store. Decide your policy before it happens. Many stores release only against the original receipt or against a written authority from the depositor, with an identity check. Record the identity document number and the receiver's name at each release. The register then shows exactly who took what, which protects the store as well as the farmer.

Why software helps most here

Rent per partial release across many lots and many months is repetitive arithmetic. Software performs it the same way every time, keeps the history and prints statements on request. It also finds a lot in seconds when a farmer rings and asks how much is left. A notebook can do this too, but search by farmer name across a thousand lots is slow.
