What the tax does to your price
A customer’s payment can contain three different amounts: the product price, sales tax collected at checkout, and the total charged. The product price is the amount set for the garment before the tax component. Collected sales tax is money received from the customer for the relevant tax account; it is not a product sale, gross profit, or funds available to pay the garment’s cost.
For pricing decisions, separate the tax component before assessing economics. The amount available to cover product cost, fulfilment, advertising and margin comes from the product price after applicable discounts and adjustments, not from the full customer charge. Treating the tax as revenue can make a product appear more profitable than it is.
The right measure depends on the question. Checkout reporting helps reconcile what the customer paid; product pricing helps assess whether the garment can support its costs; profitability reporting should use realized revenue from delivered orders and exclude returned or cancelled orders. ORVX can connect to Shopify, calculate product cost, and show gross profit, net profit and margins at product and collection level. Use the product pricing calculator to separate these components before testing a price.
| Measure | What it represents | When to use it |
|---|---|---|
| Product price | The amount assigned to the garment before the tax component | Assess cost coverage, margin and pricing |
| Collected sales tax | The tax amount included in the customer’s charge | Reconcile amounts collected for tax purposes |
| Total charged | Product price plus collected tax and any other checkout amounts | Check the customer’s payment and checkout records |
Which orders may create a collection duty
A collection review starts with the order, not just the product. Sellers typically ask four questions: Is this SKU, bundle, alteration or delivery charge treated as taxable where the order is delivered? Which customer location controls, the shipping destination, pickup location or another documented address? Does the business have activities connected with that jurisdiction, such as inventory, staff, contractors, offices or other operations? Was the order placed through a marketplace that may calculate and remit tax, or through the store’s own checkout?
These questions separate product taxability, customer location, business presence and marketplace involvement. They also help identify exceptions that need separate review, such as a customer claiming an exemption or an order involving cross-border delivery. A marketplace’s collection process does not necessarily answer every question about the seller’s own reporting position.
The legal starting point changed after South Dakota v. Wayfair. The Legal Information Institute at Cornell Law School says that, on June 21, 2018, the Supreme Court upheld a law covering sellers delivering more than $100,000 of goods or services into the state each year or making 200 or more separate transactions, and overruled the physical presence rule. Sellers should therefore track destination sales and transaction counts alongside operational presence, then evaluate the applicable state and local rules rather than applying one national assumption (Source: Legal Information Institute, Cornell Law School).
| Area | Question |
|---|---|
| Product | What is taxable about the item, bundle, alteration or delivery charge? |
| Customer | What location and customer status should be used? |
| Business | What people, property or operations connect the seller to the jurisdiction? |
| Marketplace | Who calculates, collects and remits tax for this order? |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a men's fashion store selling in the US. They are made up to show the method, they are not a benchmark, and your own figures will differ.
Formula: Tax inside an inclusive price = price - price / (1 + tax rate).
| Example tax rate | Tax on the order | Customer pays | You keep before costs |
|---|---|---|---|
| 5.0% | $3.90 | $81.89 | $77.99 |
| 8.0% | $6.24 | $84.23 | $77.99 |

Eligible Shopify stores can see these numbers for their own store through the Founding 10,000 offer.
Inclusive and exclusive prices
An inclusive price shows the amount the customer should expect to pay before any separate delivery charge. An exclusive price shows the merchandise price first, with sales tax added at checkout. Inclusive pricing can reduce surprise when customers compare the total in an advert, product page and checkout. Exclusive pricing keeps the product price clear, but the final amount can vary by the customer’s delivery location and may create checkout friction if the added tax was not anticipated.
Whichever display you choose, keep the tax component separate in internal reporting. For illustration only, an inclusive $110 payment could contain $100 of merchandise revenue and $10 of tax collected; an exclusive presentation could show $100 plus $10 at checkout. The customer-facing format changes, but the tax collected is not product revenue.
Price tests must define the measure being tested. Test inclusive pricing against inclusive pricing when the question is how the customer-paid total affects conversion. Test the pre-tax product price when the question is margin or merchandising. With exclusive pricing, compare checkout totals by destination as well as advertised prices; otherwise, a conversion difference may reflect tax presentation rather than demand. The product pricing calculator can help model both displays before a test.
| Display method | Customer expectation | Reporting and testing focus |
|---|---|---|
| Tax-inclusive | The advertised amount is closer to the expected payment. | Separate tax from revenue; test the customer-paid total. |
| Tax-exclusive | The product price is clear, but checkout adds a variable amount. | Separate tax from revenue; compare delivered checkout totals by destination. |
How to read the worked pricing example
Read the worked example from the merchandise price outward. Start with the selling price shown for the men’s fashion item. The tax amount is calculated separately, then added to that selling price to reach the customer payment: selling price + tax amount = total charged. The tax is collected from the customer, so it should not be treated as product revenue or subtracted from the selling price when assessing the item’s economics.
Next, compare the selling price with the product cost shown in the example. Gross profit is selling price − product cost. Gross margin is gross profit ÷ selling price × 100. This means the customer payment is useful for checking what was charged, while the selling price is the base for the product margin. Do not count the tax a second time in the cost calculation. The resulting margin is a product-level gross margin; it does not include advertising, fulfilment, payment fees or other operating costs. You can test the same sequence with the product pricing calculator.
Records worth keeping
Keep records that let you trace each taxable sale from checkout to the return and payment report. The goal is not only to show what tax was charged, but to explain why the order was taxable, which jurisdiction applied, and whether the amount reached the correct filing.
Store the underlying order data with the supporting evidence, rather than relying only on a monthly tax total. Reconcile store orders, payment deposits, marketplace reports, refunds and filed returns so differences can be investigated before filing.
- Order record: order number, order date, SKUs, quantities, discounts, bundles, alterations, shipping charges, product price, tax charged, refund and cancellation status, and payment channel.
- Customer-location record: ship-to address, billing address where relevant, delivery destination, and the method used to determine the applicable state and local jurisdiction.
- Exemption record: customer or organization details, exemption certificate or other supporting evidence, approval status, affected orders and the date the exemption was applied.
- Marketplace record: marketplace name, order-level sales, tax collected or remitted by the marketplace, fees, refunds and the net amount paid to your store.
- Filing record: jurisdiction, filing period, taxable and exempt sales, deductions, tax collected, tax due, payments, filing confirmation and any adjustment or correspondence.
- Pricing record: tax-inclusive or tax-exclusive display setting, price changes, effective dates, shipping-tax treatment and the calculation used to reconcile the checkout tax with the recorded merchandise price.
