The business
Optima Vitamins sells vitamins and supplements from its Shopify store at optimavitamins.us, and its site says the mission is to offer supplements that fit your lifestyle.
What a US supplement invoice has to get right
Bottles look alike. A customer unpacking four of them wants to match each one to a line on the page, so the product name, the count and the SKU all belong on the invoice.
The tax row depends on the state, and for supplements the answer is not the same everywhere. Texas exempts most dietary supplements. Other states tax them like ordinary goods, so a store that ships nationwide needs the tax row to follow the shipping address. The US has no federal VAT and no national invoice format, which leaves all of this to each state.
The seller block can hold a business tax ID. In the US that is an EIN. The invoice also stays out of product claims. It records a sale.
How Optima Vitamins uses PDF Invoice
Optima Vitamins has used the app since 2020. Its invoice template is Three Invoice. Automatic invoice emails are on, so the document reaches the customer without a manual send. The barcode option is on as well, and the sample prints the order number as a code under the title. Documents are in English, following the shop's primary language.
Five document types are ready on the account, namely the invoice, the quote, the order document, the refund and the packing slip.
Three Invoice leads with a colored strip that holds the invoice date, amount and number. The seller block sits at the top left and the customer's name and address at the top right. Below the item table, the payment method and any note sit on the left, and the totals sit on the right in a column of colored cells. The page ends with a note from the merchant and a thank-you line.
The sample uses an invented seller and customer. A shopper in Seattle, Washington buys two bottles of vitamin C, magnesium, a multivitamin and an omega-3 softgel pack. The invoice reads $114.30 for goods, a Washington sales tax row at 10.35% for $12.50, $6.50 for shipping and a $133.30 total. Every name and number on it is made up. Washington taxes delivery charges along with the goods, so the tax row covers $120.80 of goods and shipping. A Texas store selling the same four items would show no tax row at all.
Results
More than 430 documents sent since 2020. The store runs a full set of document types, with emails going out on their own.
No time savings or sales figures came from the merchant, so none are claimed.
