Billing for the goods you sell

A sales invoice typically bills a customer for physical goods, so give every product its own line: put the item description — and its SKU or product code — in the description field, the number of units in the quantity column, and the price per unit in the rate column. The tool multiplies quantity by unit price on each line and totals them for you. That's the difference from a service invoice, where you'd usually be billing hours or a flat project fee rather than counting units sold.

Set your sales tax as the single tax line — type 'Sales Tax' as the label and enter your rate as a percent. If you're giving a discount, apply it first: the one discount comes off the subtotal, and sales tax is then calculated on that reduced amount, so the customer is taxed on what they actually pay. Rates vary by state and often by county, so confirm the correct one for where the sale takes place.

A sales invoice is a request for payment, not proof of it. Once the customer pays, you can turn the same document into a receipt — open your saved draft, add 'Paid' and the date to the notes field, and download a fresh PDF. Give each invoice a sequential number (INV-001, INV-002…) and a due date so there's no doubt about when payment is expected.

Follow a wholesale order from SKU to freight

Ridgeway Packaging Supply is billing a coffee roaster for a wholesale order shipped from stock. Every product is priced per case or per roll, so the SKU and description go in the description field, the number of units in the quantity column, and the price of one unit in the rate column. Freight is added as its own line because there is no separate shipping field, and the single Sales Tax line is figured on the subtotal after any discount.

Each line carries its SKU and a per-unit price so the buyer can tick off quantities received against their own purchase order, line by line.

Buyers match these against the purchase order

  • SKU in every description

    There is no separate SKU column, so type the product code and the item description together in the line's description field — it prints on the PDF exactly as you enter it.

  • Units sold, not hours

    Put the number of units, cases or rolls in the quantity column and the price of a single unit in the rate column; the tool multiplies them on each line and adds the lines into the subtotal.

  • The right sales tax rate

    Label the one tax line "Sales Tax" and enter the combined state and local percent for where the sale takes place — it is calculated on the subtotal after any discount, so a trade discount reduces the tax too.

  • Shipping as a line item

    There is no shipping field, so bill freight or delivery as a final line at quantity 1, and check whether shipping is taxable in the destination state before you set your rate.

  • PO and resale references

    There is no PO number field either — put the customer's purchase order number and any resale or exemption certificate reference in the notes so their accounts payable team can match the invoice.

Frequently asked questions

What's the difference between a sales invoice and a receipt?

A sales invoice requests payment for goods sold, while a receipt confirms payment was made. Generate the invoice here, then once you're paid, add 'Paid' and the date to the notes field and re-download the PDF to use the same document as a receipt.

How is sales tax calculated on the invoice?

The single tax line is applied to the subtotal after any discount — enter 'Sales Tax' as the label and your percent rate, and the tool figures the amount on the discounted total automatically. Rates differ by state and county, so confirm the right one or check with an accountant.

How do I list products with SKUs or item codes?

Put the product name and its SKU together in each line's description field, the number sold in the quantity column, and the price per unit in the rate column. There's no separate SKU column, but whatever you type in the description prints on the PDF exactly as written.

Can I apply a discount before sales tax?

Yes — the tool supports one discount, as a percent or a fixed amount, taken off the subtotal before sales tax is calculated. If you need a second discount, fold it into your unit prices or spell it out in the notes field.
