Karat / Purity

Keep the list of karats and purities your shop deals in, such as 22K gold or Silver 925; each one is priced from its own daily rate.

Karat / Purity is the list of metals and grades your shop sells, such as 22K gold or Silver 925. Each one gets its own rate every morning, and every weighed line on a bill names its karat.

Before you begin

• Switch selling by weight on in Settings. That also adds 24K, 22K, 21K, 18K and S925 for you.
• You need the Manage Karat / Purity List permission to add or change one.

Where to find it

Open Jewellery → Setup → Karat / Purity.

Add a purity

1. Click Add Purity.
2. Type a short Code, for example 20K. It must be unique.
3. Type the Name, for example 20 Karat Gold.
4. Optionally type the Fineness, the fraction of pure metal. 22K is 0.916667. It is used in reports, not in pricing.
5. Set the Sort order. Lower numbers come first in the karat picker.
6. Leave Active ticked.
7. Click Save.

The new purity now appears on Today's Rate. Set its rate there before you sell at it.

Change or retire a purity

• Click Edit to change the code, name, fineness or order.
• Click Deactivate and confirm to retire one. Old bills keep it; new lines cannot choose it.

A purity is never deleted, because old invoices must still say what they were sold as.

Common questions

Does fineness change the price? No. The price comes only from the rate you set for that karat on Today's Rate.

Can I bring back a deactivated purity? Yes. Click Edit, tick Active and click Save.

Do I need a separate purity for silver? Yes. Silver has its own rate, so it needs its own row. S925 is added for you.
