The jewellery business can’t be satisfied with just knowing they have 50 kg of gold in their stock. A manufacturer, wholesaler or retailer should also know about how much 18K is, where it is kept, how much is in the finished jewellery and how much has passed through its production, sales or job work. That’s where karat-wise inventory software comes in handy.

Karat denotes the percentage of gold in an alloy, and fineness is a measurement used to indicate the purity of an alloy in parts per thousand. In India, gold jewellery is classified into various grades such as BIS 18K (750), BIS 22K (916), and BIS 24KS (995), etc.

An inventory system for jewellery needs to be more than just about quantity. It should be able to relate karat, fineness, weight, product, location, and stock movement, so that the owner of the business could easily reconcile the stock with the business system.

What Is Karat-Wise Jewellery Inventory?

A gold inventory system for jewellery by karat is one way of maintaining and controlling gold stocks along with weight, product, and location. The system treats all gold as one stock category, except for inventory like 18K, 22K and applicable 24K grades.

This is important because 10 grams of 18K gold is not equal to 10 grams of 22K gold containing the same amount of fine gold.

For instance, if you choose the nominal fineness values:

Gold grade	Fineness	Approximate amount of fine gold in 10 g
18K	750	7.50 g
22K	916	9.16 g
24KS	995	9.95 g

The formula is simple: gross gold weight multiplied by its fineness and then divided by 1,000.

This calculation should not be used instead of the business’s actual stock records, assay procedures or accounting policies, however, for operational inventory. It is also good practice for jewellery companies to differentiate between the weight of the metal and the weight of the stones and other non-gold components.

According to BIS, hallmarking is the official determination and recording of the content of precious metals, and according to its consumer guidance, the contents of an invoice for hallmarked articles of precious metals shall show the description of the article, the net weight

Why Do Jewellers Need to Track 18K, 22K and 24K Separately?

Different purities can be aggregated into a “gold stock” figure, which can cause visibility loss for a jewellery business.

Think of a manufacturer who has:

• Traditional jewellery: 8 kg of 22K gold.
• Selected designs in 3kg gold.
• 1 kg of gold with a higher purity level (for special production or material needs)

The total of 12 kg does not indicate to the production manager the material available for an order.

Karat-wise tracking answers more helpful questions:

• How much 22K stock does he have left?
• What material is in production that is 18K?
• How many golds does a job worker have issued to him?
• How many of the quantity are back?
• To whom is the stock sold?
• What percentage of the finished jewellery is in each of the purity classes?
• Is there any balance between physical and system balances?

This is especially significant if inventory is transferred from raw material to work-in-process, finished goods, showroom stock, branch stock and job work.

Currently, Karat ERP’s product information describes the control of precious metals and diamonds/stones inventory along with support for barcodes, QR codes and RFID.

How Should a Jewellery Business Track Gold by Karat?

The first step in a helpful inventory workflow for karat pieces is to establish the attributes that apply to the business and not just to have separate folders for “18K”, “22K” and “24K”.

1. Define the purity and fineness

The karat and fineness applicable should be identified by the inventory master.

However, BIS specifies that 18K is 750 for the Indian jewellery business while 22K is 916. Furthermore, in its FAQ, it lists 24KS as 995.

2. Record weight correctly

The system should make a distinction between relevant weight fields, not just one number.

With a diamond ring, for instance:

Here are the steps to go through when converting to stone weight. Here are the steps to take when converting from gross weight to stone weight.

This is significant for inventory analysis and documentation.

3. Connect material to the product

It is not the finished product to be recorded as “Ring – 8.2 g”.

It is more useful to be able to record on an inventory record the product, purity, weight, stones, and stock status and location.

4. Track every movement

Movement of material from Warehouse to Production, Production to Job Work, or Finished Goods to Showroom should be reflected in the stock record.

5. Reconcile physical and system stock

Frequent reconciliation helps to find out differences before they become hard to investigate.

It’s particularly beneficial for organizations with numerous pieces in workshops, warehouses, and retail stores.

A Practical Example: 22K Stock Moving Through Manufacturing

Suppose a jeweller has received an order for 422K bangles.

Initially, the business has 22K of raw material. That material goes to production, some into job work, and the finished bangles ultimately into finished-goods stock.

One possible system flow is:

The raw material is supplied to the jeweller, and then he/she encounters problems in the production or manufacturing line, and then the work-in-progress is taken to the job workman (if any) or to finished jewellery, and then to the jeweller’s showroom/warehouse or to the customer.

The business requires transparency on what has occurred in each stage.

Assume that 1,000 grams of 22K material is given to production. It is the production team’s responsibility to have only one spreadsheet for the issue, and not for job work and finished stock.

A connected inventory workflow can facilitate the movement to be tracked.

This doesn’t mean software eliminates the need for physical verification. Rather, it provides the business with a systemized document that can be compared to the physical inventory, production records, and transactions.

Karat-Wise Inventory vs. Basic Stock Tracking

The distinction is becoming more apparent when looking at both approaches.

Basic stock tracking	Karat-wise jewellery inventory
Tracks quantity	Monitors quantity, purity, and weight
Product-level visibility might be restricted	Product and purity attributes can be associated
Gold can be grouped as one category.	18K, 22K (and other applicable grades) can be differentiated
Manual reconciliation is frequently used	Structured reconciliation involves using system records as a basis for driving reconciliation in the structured manner outlined above.
Production may be separate production movements.	Inventory is linked to production processes
Poor visibility from one place to another.	Tracking more than one location can offer increased stock visibility.

The objective isn’t to create more data for the sake of it. The aim is to record data which would impact valuation, production decisions, stock control and documentation.

According to Karat ERP, its ERP provides multi-location inventory, real-time reporting, barcode/RFID tracking, and manufacturing workflows.

Common Mistakes in Gold Purity Inventory Management

Gold is considered as one inventory category.

There may be significant differences in the purity of a single “gold” balance.

Better solution: keep purity/karat as an important stock characteristic.

Adding gross weight to net metal weight

Diamonds, gemstones, or other objects may be in a jewellery piece. This can lead to inaccurate inventory analysis if gross weight is assumed to be pure-metal weight.

Better approach: keep the respective weight components separate.

Creating a production outside of the inventory system.

It can be difficult to reconcile production, job work, and stock records when they are kept in separate files.

Better approach: correlate material issues, production, job work, finished goods wherever it works for the software.

Ignoring branch-level inventory

A business can have a good total stock but not sufficient stock at a specific showroom.

Improved solution: inventory by location, by purity.

Assuming software automatically makes records compliant

While documentation and processes can be aided by inventory software, the compliance will rely on the correct configuration of the software, business practices, and regulations that apply.

For instance, CBIC has issued a GST FAQ for the sector which clarifies that the end consumer of gold jewellery is liable to pay 3% of the total transaction value of jewellery, which includes making charges displayed separately.

Tax and compliance configurations should therefore be checked with a qualified tax professional or accountant.

What Should You Look for in Karat-Wise Inventory Software?

Here are some practical questions you should ask before choosing jewellery inventory software:

• Are there two or more karats and fineness values that can be differentiated by the system?
• Is it able to measure gross, stone and net weights of precious metals separately, if necessary?
• Are inventories moving between warehouses, branches and production tracked?
• Is it possible to put barcodes, QR codes and/or RFID on stock?
• Is it possible to track job-work and production movements?
• Are stock reports possible for the system that are useful for operations and management?
• Will it fit in with the current business processes, or will it have to be categorized and processed as retail?
• Is the implementation team able to design the system to reflect the business’s specific inventory?

The last question is usually neglected. The procedure of dealing with alloys, manufacturing, job work, branches, memo, stones, and finished goods varies among jewellery stores. The first step in a good implementation is to know those workflows.

According to Karat ERP, the process of system study is where they analyse the workflows such as inventory, orders, and accounts before you begin installing Karat ERP. It is also available to customise, implement, train users, and to support them during the go-live.

How Karat ERP Supports Karat-Wise Jewellery Inventory

Karat ERP offers manufacturers, wholesalers and retailers an industry-specific ERP environment, which integrates all the processes of inventory, production, purchasing, sales and finances. Today, it’s products information defines the stock control of precious metals, diamonds and colour stones, and the barcode, QR and RFID tracking.

The ERP further offers manufacturing and production management features like work-in-progress tracking and loss control for companies where manufacturing is their primary business.

Karat Retail Software is used by retailers to handle stock, invoices, payments, and generate barcodes and is referred to as integrated with Karat ERP.

This can be helpful when a business requires visibility during inventory to span from manufacturing/warehouse to the showroom.

According to its current product pages, Karat ERP also features a mobile app that can be used to perform ERP functions and check inventory, sales, and business processes remotely.

The configuration depends on the operating model, purity structure, locations, production process, and users of the business. It’s prudent to show real-world jewellery workflow and data in the specific modules that each jewellery company requires, as opposed to assuming they all do.

Conclusion

The bottom line with karat-wise inventory is to provide jewellery businesses with a better understanding of what their gold holdings are really worth. A single consolidated gold balance is not as useful an operational number as tracking 18K, 22K and applicable 24K grades in conjunction with weight, product, location and movement.

The next level up for manufacturers, wholesalers and retailers is to trace the flow of gold in the purchase of raw material, production, job work, finished stock and sale. Then test if the inventory system can accurately replicate that workflow. For those needs, which go beyond stock counting, there is the possibility of considering a jewellery-specific ERP like Karat ERP.

Frequently Asked Questions

1. What is karat-wise inventory software?

Karat-wise inventory software keeps track of jewellery or gold stocks by purity or karat with other factors like weight, product, location, etc. For an Indian jeweller, this can be a way to differentiate 18K, 22K, and applicable 24K grades rather than lumping them together to make a single gold-stock figure.

2. What is the difference between 18K and 22K gold inventory?

Under the BIS grades of gold jewellery, 18K gold is of 750 standard and 22K gold is of 916 standard. Hence, it is important to have a stock analysis from a purity aspect when dealing with a jewellery shop’s inventory, because two different percentages of fine gold would exist in items of equal weight for 18K versus 22K jewellery.

3. Should jewellery inventory track gross weight and net gold weight separately?

Yes, the relevant weight components should be distinguished as jewellery can contain diamonds, gemstones or other material. BIS consumer guidance specifically refers to net precious-metal weight, purity in carat and fineness for invoices of hallmarked precious-metal articles.

4. Can karat-wise inventory software track gold used in manufacturing?

As long as there is software that enables the manufacturing and inventory processes. An appropriate system should be capable of linking material with production and finished goods records. Currently, Karat ERP is defined as manufacturing management, WIP tracking, and precious metals inventory management.

5. Is Karat ERP suitable for jewellery businesses that need purity-wise inventory?

Yes, Karat ERP can be used in jewellery companies aiming for purity-wise stock.

Karat ERP is specifically built for jewellery manufacturing, wholesale, and retail jewellery companies and currently includes the following inventory control features: precious metal, barcode, QR and RFID, manufacturing management, and multi-location support. The solution should be demonstrated, and the karat, weight, production, and reporting requirements of a specific business must be covered in that configuration.
