Gold Sales Invoice: What It Must Show (With an Example)
A gold sales invoice should show, as separate lines, the item description, its purity (karat or fineness), the net gold weight, the gold rate used, the resulting metal value, the making or labour charge, any stones, applicable taxes and the total. When metal value and labour are blended into one figure, buyback, exchange and audit questions become hard to answer.
Jewellers often treat the invoice as paperwork that follows the real sale. In fact, it is the document customers return with when they want to exchange a piece, sell it back or claim insurance, and it is the first thing an auditor asks for. This guide explains what a jewelry or gold sales invoice should contain, works through a hypothetical example line by line, shows how to handle karat conversion and trade-ins, and lists the warning signs of a suspicious invoice. Rules on mandatory invoice content and tax differ by country, so use it as a practical checklist and confirm the legal details with your accountant.
What a gold sales invoice must show
Most invoices in the jewelry trade have three parts: the parties, the item lines and the financial summary. The table below covers the lines that matter most.
| Invoice field | What to record | Why it matters |
|---|---|---|
| Invoice number and date | Sequential number, date and ideally time of sale | Traceability; prevents duplicates |
| Seller and buyer details | Business name, address, registration where required; customer name and contact | Identifies both parties for returns or disputes |
| Item description and code | Type of piece, design reference, stock code | Matches the sale to inventory |
| Purity | Karat (18K, 21K, 22K) or fineness (750, 875, 916) | Gold rates are quoted for a specific purity |
| Gross and net weight | Total weight and gold-only weight, in grams | Stones should not be priced as gold |
| Gold rate | Rate per gram used at the moment of sale | Shows the basis of the metal value |
| Metal value | Net weight × rate, after purity conversion if needed | The part that usually counts at buyback |
| Making charge | Amount or percentage for labour and design | Usually not refunded when selling back |
| Stones and extras | Gemstones, certificates, engraving | Priced separately from gold |
| Taxes | VAT or sales tax as required locally | Rate and base vary; ask your accountant |
| Total and payment | Grand total, payment method, trade-in credit | Basis for settlement and customer balance |
The single most useful habit is keeping metal value and making charge apart. Customers then understand why a piece sold back the next week returns less than they paid. For more on labour pricing, see our article on gold making charges.
Worked example: an itemised jewelry invoice
All figures below are hypothetical and chosen only to show the method. Real gold rates, labour and margins vary by market and shop. Suppose a customer buys an 18K necklace with a net gold weight of 10 g. The hypothetical rate for 18K gold is 60 currency units per gram, the making charge is 12% of the metal value, and the shop margin is 5% of metal plus labour.
| Line | Calculation | Amount (hypothetical) |
|---|---|---|
| Metal value | 10 g × 60 | 600.00 |
| Making charge | 12% × 600 | 72.00 |
| Shop margin | 5% × 672 | 33.60 |
| Subtotal before tax | Metal + making + margin | 705.60 |
| Tax | According to local rules | Confirm with your accountant |
A note on tax: in some jurisdictions VAT applies to the full price of jewelry, in others special schemes exist for investment gold or second-hand goods, and the rules change from time to time. Do not copy a rate from another country or another shop. Set it up once with your accountant and print it as its own line.
Converting purity on the invoice
Many markets quote a reference rate for one purity, such as 18K or 24K. If the piece has a different purity, convert its weight to the reference before pricing. Hypothetical example: a 21K ring (about 875 fineness) weighing 4 g equals 4 × 875 ÷ 750, roughly 4.667 g of 18K gold. Showing both the actual and the equivalent weight on the invoice makes the price easy to check. Our guide to gold karat conversion covers the arithmetic in more detail, and how gold jewelry prices are calculated explains the full price build-up.
Trade-ins: one sale, two documents
A large share of jewelry sales involve an old piece handed over as part payment. The tidy way to record this is with two documents: a purchase invoice for the customer’s old gold (weight, purity and buying rate at that moment) and a normal sales invoice for the new item. The value of the purchase then appears as a payment line on the sales invoice. This keeps your stock of scrap or second-hand gold correct and gives a clear answer if the customer later asks what rate they received. Buying and selling rates are often different, and the documents should make that visible.
Invoice, receipt or certificate: which document does what?
Customers sometimes leave with three pieces of paper and no idea which one matters. The invoice is the record of the sale and its price build-up. A till receipt proves payment but usually lacks the detail needed for buyback or insurance. A stone or quality certificate describes a gemstone or the metal itself and is issued by a lab or the manufacturer, not by the sale. Tell customers to keep all three together; when they return to sell or exchange, the invoice is what lets you check weight, purity and labour quickly and settle without argument.
Checklist before you hand over the invoice
- Weigh the piece in front of the customer and record the weight to the precision of your scale.
- Note the purity from the hallmark or supplier documents; record any conversion.
- Record the gold rate with the time of sale, especially on volatile days.
- Put making charge, margin and stones on separate lines.
- Record any trade-in on its own purchase document.
- State the payment method and any outstanding balance.
- Explain your exchange and buyback policy, or print it on the invoice.
- Keep a copy in your records for as long as local rules require.
Red flags: how to spot a suspicious invoice
- Rate out of line: an invoice priced well away from the rate recorded for that day.
- Odd purity: a purity that does not fit the item, for example a fashion piece entered as bullion fineness.
- Wrong direction: a purchase booked as a sale, or the reverse.
- Silent edits: weight or price changed after the goods left the counter, without a note.
Checking these by hand at the end of a busy day rarely happens consistently. It is far more reliable when the system flags them automatically.
Gold invoicing software: what Zaran does
Zaran is P-Soft’s gold and jewelry accounting software. The software speaks Persian and was designed for jewellers in Iran, yet the way it builds an invoice mirrors the principles in this guide:
| Invoice-related feature | Start | Pro | Elite |
|---|---|---|---|
| Sales and purchase invoices with weight, purity, making charge and price; automatic purity conversion; per-gram and per-mithqal rates | Yes | Yes | Yes |
| Per-customer balances kept apart for money, gold and coins; statements by period | No | Yes | Yes |
| Customer app orders with price lock | No | Yes | Yes |
| Automatic flagging of suspicious invoices and full log of user changes | No | No | Yes |
On the Elite plan, invoices with an inconsistent trade direction, purity or rate are flagged automatically, and every change a user makes is recorded.
Frequently Asked Questions
What should be on a gold jewelry invoice?
Description, purity, net weight, gold rate, metal value, making charge, stones, taxes as required locally, total, date and both parties’ details.
Why separate the making charge from the gold value?
Because buyback is usually based on metal value only. A separate line avoids disputes later.
Is VAT charged on gold jewelry?
It depends on the country and type of gold. Confirm the rate and base with your accountant.
Should stone weight be included in the gold weight?
No. Record gross and net weight and price stones on their own line.
Does Zaran work in English?
No, Zaran’s interface is Persian and designed for the Iranian gold trade.
