Supply Catalog

The Supply Catalog is the master list of all agricultural materials used in your farm. Just like Field Tasks, supplies are designed to be created only once and then reused across all inventory movements (Entries, Exits, and Returns).

1. Units: Buying vs. Consumption

One of the most powerful features of the system is the ability to handle different units for purchasing and field application.

Buying Unit

This is how you purchase and store the supply. Examples include:

• Bags (e.g., Fertilizer)
• Litres or Gallons (e.g., Liquid Pesticide)
• Bottles or Containers

Consumption Unit

This is how you apply the supply in the field. Examples include:

• Kilograms (kg) or Grams (gr)
• Cubic Centimeters (cc) or Milliliters (ml)

Unit Conversion

The Unit Conversion factor tells the system how many consumption units are in one buying unit.

Supply	Buying Unit	Consumption Unit	Unit Conversion	Explanation
Urea	Bag	kg	50	1 bag contains 50 kilograms.
Herbicide	Litre	cc	1000	1 litre contains 1000 cubic centimeters.
Fertilizer	Container	gr	5000	1 container contains 5000 grams.

Same Unit

If you buy and use a supply in the same unit (e.g., buying a “Unit” of a spare part and using a “Unit”), set the consumption unit to “Same as Buying Unit”. The conversion will automatically be 1.

2. Understanding WAVCO

WAVCO stands for Weighted Average Cost. It is the financial heart of the supply module.

Unlike simple average pricing, WAVCO takes into account the quantity of items already in stock and their cost, and averages them with the quantity and price of new purchases.

Why is this useful?

As prices from providers fluctuate due to inflation or market changes, WAVCO ensures that the cost assigned to your field tasks represents a fair “blended” price of all units currently sitting in your warehouse.

Example:

1. You have 10 units bought at $10 each (Total Value: $100).
2. You buy 10 new units at $20 each (Total Value: $200).
3. Your new WAVCO is $15 ($300 total value / 20 units).
4. When you record an exit, the system will use $15 as the cost, regardless of whether you are physically using an “old” or “new” bottle.

3. Transaction History & Devolutions

Each supply has a detailed Show View (Navigate to Supplies → Click on a Supply) that serves as a complete audit trail.

Inventory Snapshot (Time Travel)

The system allows you to see exactly how much stock and what the average price was at any specific date in the past. This is useful for end-of-month audits or reconciling physical counts.

Transaction Table

You can see every Entry, Exit, and Return in chronological order, including:

• Who provided or applied the supply.
• The exact price and quantity used.
• The total financial impact of the movement.

Devolutions (Returns)

If a contractor returns unused supply to the warehouse after an exit was recorded, you can create a Return.

1. Find the specific Exit in the transaction table.
2. Click the Return button.
3. Specify the quantity being returned.
4. The system will automatically increase the stock level and adjust the inventory value.
