The grid, from your formula
Set the base rate, the rate for FAT and the rate for CLR, and the grid fills in. A column can then be adjusted by FAT. FAT 5.1 and above has its own base.
Milk rate chart software that dates every change
The rate stays on each entry. When a supplier says last month's rate was higher, open that day and show him.

What sits on the rate screen
Cow and buffalo each have a tab. Your chart is one FAT by CLR grid, shaded by rate so a wrong cell stands out.
One market line
When the dairy moves the rate up or down, change the market line for cow or buffalo. The whole chart moves with it, and you do not edit cell by cell.
Your SNF formula
The default is (CLR / 4) + (0.21 × FAT) + 0.36. An administrator can change it to match the formula your dairy goes by.
A worked example
The market line goes up by ₹0.50
Price History lists each saved change with the date, the milk type, and the rate before and after, read at one fixed test point so two rows can be compared: FAT 5.0 and CLR 27 for cow, FAT 6.1 and CLR 27 for buffalo.
On a 500 litre lot, ₹0.50 a litre is ₹250 a shift. That is the kind of money a supplier remembers, and the reason the date matters. The figures here are an example.
Each saved entry keeps its own rate, so changing the chart today does not touch last month's entries or bills. Open that date in the day register and the rate paid is on every row.

Step 1 of 3
Open the day
Pick the date in the day register. Every entry shows the rate it was saved with.
Step 2 of 3
Open Price History
It shows when the chart changed and by how much, so you can point to the date.
Step 3 of 3
Go back if you need to
An administrator can restore a saved chart. The app asks first, then replaces the current formula, FAT adjustments, buffalo offset and market line.
What the rate chart cannot do yet
A saved chart applies from that moment: you cannot set a chart to start on a future date. There is no Excel import, and no separate chart for one supplier. Price History shows the last 40 changes and opens only with the internet on, so change rates while online. If you correct an old entry, its rate is worked out from today's chart unless you type the rate yourself.
Make a rate chart freeCan I change the rate chart myself?
Yes, any time, the same day. An operator cannot change it unless you allow it, and restoring an old chart is for administrators.
Yes, any timeIf I change the rate today, will old bills change?
No. Each entry keeps the rate it was saved with, so past entries and bills stay as they were. The new chart applies to new entries.
No, they stayCan I keep different rates for cow and buffalo?
Yes. Cow and buffalo have their own tabs, and FAT 5.1 and above runs on its own base rate.
Yes, separate tabsCan the chart go by FAT and SNF instead of FAT and CLR?
The chart is set by FAT and CLR, and SNF is worked out from the two. If your dairy pays on a FAT and SNF chart, ask us on WhatsApp before you start.
