Learn how to create Stock Items in TallyPrime and configure Units of Measure (UOM). This step-by-step guide explains simple units, compound units, decimal settings, stock groups, and inventory management with practical business examples.
How to Create a Stock Item in TallyPrime and Set Its Units of Measure
Managing inventory accurately is an important part of running any trading, retail, wholesale, or manufacturing business. Whether you sell mobile accessories, groceries, clothing, electrical products, or raw materials, keeping proper stock records helps you understand how much inventory you have, how much you sell, and when you need to purchase more.
In TallyPrime, you can manage your inventory by creating Stock Items and assigning the correct Unit of Measure (UOM) to each product. For example, you can maintain rice in kilograms, soft drinks in bottles, fabric in metres, and electronic accessories in pieces.
Once you configure these details correctly, TallyPrime can automatically update stock quantities when you record purchase and sales transactions.
In this guide, you'll learn how to create stock items, configure units, use different measurement units, and avoid common inventory management mistakes in TallyPrime.
What Is a Stock Item in TallyPrime?
A Stock Item represents an individual product, material, or inventory item that your business purchases, sells, manufactures, or stores.
For example, if you run a grocery store, your stock items might include:
Basmati Rice
Wheat Flour
Cooking Oil
Sugar
Tea Powder
Packaged Biscuits
Each stock item can have its own unit of measurement, opening balance, stock group, and other inventory details.
TallyPrime uses this information to maintain stock quantities and calculate inventory values.
What Is a Unit of Measure (UOM)?
A Unit of Measure defines how you count or measure a particular stock item.
Different products require different measurement units depending on their nature.
For example:
| Product | Unit of Measure |
|---|---|
| Rice | Kilogram (Kg) |
| Cooking Oil | Litre (Ltr) |
| Mobile Phone | Pieces (Pcs) |
| Cotton Fabric | Metre (Mtr) |
| Cement | Bags |
| Eggs | Dozen |
| Gold | Gram (Gm) |
Choosing the correct unit is important because TallyPrime uses it to calculate stock quantities during purchase, sales, and inventory transfers.
For example, if you purchase 100 kg of rice and sell 25 kg, TallyPrime can show the remaining stock as 75 kg.
How to Create a Stock Item in TallyPrime
Follow these steps to create a new stock item.
Step 1: Open the Stock Item Creation Screen
First, open your company in TallyPrime.
Follow this navigation:
Gateway of Tally → Create → Stock Item
Alternatively, you can press Alt+G (Go To), search for Stock Item, and open the creation screen.
Step 2: Enter the Stock Item Name
In the Stock Item Creation screen, enter the product name in the Name field.
For example:
Name: Basmati Rice
Under: Primary
If you have already created a relevant Stock Group, select that group instead of Primary.
Using meaningful product names makes it easier to identify items during purchase and sales entries.
Step 3: Select the Stock Group
The Under field allows you to assign your stock item to a Stock Group.
For example, if you operate a grocery business, you might organise your inventory like this:
Grocery Items
Rice
Wheat Flour
Pulses
Beverages
Soft Drinks
Fruit Juices
Household Products
Cleaning Supplies
Detergents
You can select an existing group or create a new one when required.
Organising products into groups helps you analyse inventory category-wise.
Step 4: Select the Unit of Measure
In the Units field, select the appropriate unit for your product.
For example:
Basmati Rice: Kg
Cooking Oil: Ltr
Mobile Phone: Pcs
Cotton Fabric: Mtr
If the required unit is not available, you can create a new unit by opening the Unit Creation screen.
We will explain this process in the next section.
Step 5: Enter Opening Balance (If Applicable)
If you already have stock available when starting to use TallyPrime, enter its opening balance.
For example:
| Field | Value |
|---|---|
| Opening Quantity | 100 Kg |
| Rate | ₹80 |
| Opening Value | ₹8,000 |
TallyPrime can use these details to establish your initial inventory position.
If you are creating a completely new item and have no existing inventory, you can leave the opening balance blank.
Step 6: Save the Stock Item
After entering the necessary information, press Ctrl+A to save the stock item.
Your new product is now available for use in purchase, sales, and other inventory transactions.
How to Create a New Unit of Measure in TallyPrime
Sometimes, the default units available in TallyPrime may not match your business requirements.
For example, you might sell products in cartons, boxes, packets, rolls, or bundles.
In such cases, you can create custom units of measurement.
Step 1: Open Unit Creation
Go to:
Gateway of Tally → Create → Unit
Alternatively, use Alt+G (Go To) and search for Units.
Step 2: Select the Unit Type
TallyPrime supports two main types of units:
Simple Unit: Used when products are measured using a single standard unit.
Examples:
Kg
Ltr
Pcs
Mtr
Box
Packet
Compound Unit: Used when one unit is made up of another unit.
For example:
1 Box = 10 Pieces
1 Dozen = 12 Pieces
1 Case = 24 Bottles
Compound units are useful when you purchase and sell the same product using different quantities or packaging measurements.
Step 3: Enter the Unit Details
For a simple unit, enter the following information:
| Field | Example |
|---|---|
| Type | Simple |
| Symbol | Box |
| Formal Name | Box |
| Number of Decimal Places | 0 |
The Symbol is the short name displayed in inventory transactions, while the Formal Name describes the unit.
For example, you can use Kg as the symbol and Kilogram as the formal name.
Step 4: Save the Unit
After entering the required information, press Ctrl+A to save the unit.
You can now select this unit while creating a stock item.
How to Create Compound Units in TallyPrime
Compound units are particularly useful when your business purchases products in bulk but sells them individually.
For example, suppose you purchase soft drinks in cartons and sell them as individual bottles.
You can create a compound unit with the following relationship:
1 Carton = 24 Bottles
Follow these steps:
Step 1: Open Unit Creation
Go to Gateway of Tally → Create → Unit.
Step 2: Select Compound Unit
Choose Compound as the unit type.
Step 3: Define the Conversion
Enter the following details:
| Field | Value |
|---|---|
| First Unit | Carton |
| Conversion Factor | 24 |
| Second Unit | Bottle |
This establishes the relationship:
1 Carton = 24 Bottles
Step 4: Save the Compound Unit
Press Ctrl+A to save the configuration.
You can now use the compound unit when creating suitable stock items.
The conversion allows TallyPrime to maintain quantities consistently when transactions use the defined units.
Practical Example: Creating a Stock Item with Units
Let's understand the complete process using a real-world business example.
Suppose you operate a wholesale beverage business. You purchase soft drinks in cartons and sell individual bottles to customers.
Your inventory setup could look like this:
| Details | Configuration |
|---|---|
| Stock Item | Soft Drink |
| Stock Group | Beverages |
| Primary Unit | Bottle |
| Compound Unit | Carton |
| Conversion | 1 Carton = 24 Bottles |
| Opening Stock | 10 Cartons |
| Total Quantity | 240 Bottles |
Now suppose you purchase 5 additional cartons.
Your total inventory becomes:
10 Cartons + 5 Cartons = 15 Cartons
Since each carton contains 24 bottles:
15 × 24 = 360 Bottles
If you sell 60 bottles, the remaining stock will be:
360 − 60 = 300 Bottles
This type of inventory setup helps businesses maintain accurate stock records without manually converting every quantity.
How to Set Decimal Places for Units of Measure
Some products require decimal quantities rather than whole numbers.
For example:
Rice: 2.500 Kg
Cooking Oil: 1.750 Ltr
Fabric: 5.500 Mtr
Gold: 10.250 Gm
When creating a unit, you can specify the number of decimal places.
| Unit | Suggested Decimal Places |
|---|---|
| Pieces | 0 |
| Boxes | 0 |
| Kilograms | 3 |
| Litres | 3 |
| Metres | 3 |
| Grams | 3 |
These are practical examples, not mandatory settings. Choose decimal precision according to how your business measures and sells products.
Using suitable decimal settings helps record fractional quantities accurately.
Common Mistakes to Avoid When Creating Stock Items
Even a small mistake in inventory configuration can cause problems in stock reports and transaction entries.
Here are some common mistakes to watch out for:
Choosing the Wrong Unit: Assigning Pieces instead of Kilograms can create incorrect inventory records.
Using Different Names for the Same Product: Avoid creating duplicate stock items such as Rice 5 Kg and Rice-5KG unless they represent genuinely different products.
Ignoring Compound Units: If you purchase cartons but sell individual pieces, configure the appropriate unit conversion.
Entering Incorrect Opening Stock: Always verify the initial quantity and valuation before saving opening balances.
Creating Too Many Stock Groups: Keep your inventory structure simple and organised. Too many unnecessary groups can make stock management confusing.
Ignoring Decimal Settings: Products sold by weight, length, or volume may require decimal quantities.
Benefits of Creating Stock Items and Units Correctly
Setting up stock items and units properly offers several advantages:
Accurate Inventory Tracking: Monitor available stock quantities.
Faster Purchase Entries: Select products and units without repeatedly entering details.
Better Sales Management: Record product sales using the correct measurement units.
Reduced Calculation Errors: Use defined unit conversions instead of manual calculations.
Improved Stock Reports: Understand inventory quantities and values more easily.
Better Business Decisions: Identify fast-moving products and manage purchasing requirements.
