Your price is more than a number on a product page. It determines whether each sale contributes to growth, or quietly loses money after platform fees, fulfilment, tax and currency conversion.
Use this playbook to build a repeatable pricing system for your ecommerce, digital or SaaS business as you enter new markets.
Start with the margin you need, not a competitor’s price
Competitor prices can help you understand the market. They cannot tell you whether a sale will be profitable for your business.
Start with your net selling price, excluding VAT, GST or sales tax. Then deduct costs that change with each sale:
- Product or service delivery costs
- Marketplace and payment-processing fees
- Pick, pack, postage and fulfilment
- Discounts, refunds and returns allowance
- Customer support or usage costs
- A reasonable allocation for compliance and operating costs
A useful starting formula is:
Required net price = fixed per-sale costs ÷ (1 − percentage fees − target contribution margin)
For example, suppose a product costs £34 per sale before percentage-based fees. That total includes the item, fulfilment, an allowance for returns and an allocated operating cost. If platform and payment fees together are 15% of the net selling price, and you want a 35% contribution margin:
£34 ÷ (1 − 0.15 − 0.35) = £68 net selling price
At that price, the £34 in fixed per-sale costs and £10.20 in percentage-based fees leave £23.80 contribution. That is 35% of the £68 net price.
This is an illustrative model, not a universal margin target. Check how each platform calculates its fees. Some fees may apply to the tax-inclusive transaction value, shipping or other charges. Model the actual fee basis to avoid overstating your margin.
Keep sales tax out of your revenue and margin
VAT, GST and sales tax collected from customers are not sales revenue available to fund your business costs. Keep them separate in your pricing model and bookkeeping.
For a tax-inclusive price, work backwards to find the net amount. For example, if a product is priced at £120 including a 20% VAT rate, the net sale is £100 and the VAT element is £20. Calculate margin using £100-not £120. The applicable VAT rate depends on the product, service and place of supply, so verify the correct treatment before setting prices.
Where consumer prices must be shown inclusive of tax, build the tax into the displayed amount and preserve your required net price. The European Commission’s consumer pricing guidance explains that consumers should be informed of the full price, including taxes and charges, before purchase.
In the United States, sales tax is commonly added at checkout when you have a duty to collect it. That duty can depend on the state, your business activities, product taxability and marketplace arrangements. There is no single nationwide consumer sales-tax rate. Check state requirements, and review the Streamlined Sales Tax remote seller resources as one starting point.
For Canada, Australia and the EU, identify the applicable GST/HST or VAT rules for the sale and customer location before deciding how to display tax. Do not assume that every product, service or transaction receives the same treatment.
Set a local price without letting currency movements erode it
A straight currency conversion is a useful starting point, not a complete international pricing strategy. It may produce awkward local prices, ignore payment-provider conversion charges and leave your margin exposed if exchange rates move.
Build a short pricing policy for each market:
- Choose your base accounting currency.
- Set the minimum acceptable net margin.
- Record the exchange rate and date used to create each local price.
- Add a documented buffer for expected currency movement and conversion costs.
- Round to a customer-friendly local price only after checking the resulting net margin.
- Set a trigger for reviewing the price if exchange rates move beyond your tolerance.
For example, if your target price translates to US$87.55 at your planning rate, you might test a local price point such as US$89. Then recalculate the net proceeds after any sales tax, marketplace fees and currency conversion. Do not let attractive rounding conceal a margin shortfall.
Keep pricing currency assumptions separate from tax-accounting currency rules. The rate used to create a storefront price may not be the right rate for recording a transaction or calculating a tax return. Check the applicable rules, including HMRC’s guidance on foreign-currency VAT transactions and the IRS guidance on foreign currency and exchange rates.
Localise your offer for each market
Local pricing means more than changing the currency symbol. It means checking how customers see the price, what costs apply to serving them, and how indirect tax is handled.
| Market | Pricing checks before launch |
|---|---|
| USA | Model state-specific sales-tax collection obligations and marketplace fees. Check whether tax is added at checkout and confirm your product’s tax treatment in relevant states. |
| Canada | Check whether GST/HST or other applicable provincial tax affects the transaction. For digital businesses, review the CRA’s cross-border digital-economy GST/HST guidance. |
| Australia | Include Australian GST obligations, payment costs and fulfilment in your price model. Check current registration and collection requirements with the Australian Taxation Office. |
| EU | Verify VAT treatment and registrations country by country. For consumer-facing prices, account for rules requiring the full price to be visible before purchase. VAT registration and filing obligations may also affect your administration costs. |
These are launch checks, not a substitute for assessing your actual products, customer types and sales channels. For a broader overview of the operational considerations, see our USA, Canada and Australia market comparison.
Review pricing when costs change, not just when sales slow
A quarterly review gives you a regular opportunity to catch margin drift. But do not wait for quarter-end if an important cost changes suddenly.
Review a price sooner when:
- A supplier, shipping or fulfilment cost changes materially.
- A platform adjusts its commission or fee structure.
- Payment-processing or currency-conversion costs increase.
- A tax rate, tax treatment or collection obligation changes.
- Refunds or returns rise above your modelled allowance.
- Exchange rates move beyond your documented review threshold.
- A product’s contribution margin falls below your minimum.
Track margin by market and sales channel, not only across the business as a whole. A strong UK result can hide a loss-making marketplace, product or currency.
Two fictional illustrations: turn the model into action
Fictional illustration: Ecommerce seller. A UK accessories brand sells through its own store and a marketplace. Its original US price was converted from sterling once and left unchanged. After reviewing marketplace fees, international fulfilment, returns and currency conversion, the team found that US orders had a lower contribution margin than expected. It rebuilt the price from the net margin target, documented its USD exchange-rate assumption and set an FX review trigger. It also separated tax collected from sales revenue in its reporting.
Fictional illustration: SaaS business. A UK software company priced every subscription by converting its sterling plan into local currency. The resulting Canadian and Australian prices looked inconsistent and shifted with exchange rates. The team set stable local subscription prices, recorded the rate and buffer used to establish them, and reviewed the customer-facing tax treatment separately. It then compared net receipts by market after payment fees and applicable tax. That gave the team a clearer basis for price updates and revenue reporting.
Use this monthly and quarterly pricing checklist
Each month:
- Compare realised net revenue and contribution margin by market, product and channel.
- Reconcile marketplace, payment and fulfilment fees against actual statements.
- Check refunds, discounts and shipping costs against your assumptions.
- Confirm that tax collected is recorded separately from revenue.
- Review exchange-rate movement against your documented pricing thresholds.
Each quarter:
- Rebuild your margin model using current supplier, platform and service costs.
- Check market-specific price points and confirm they still protect your target margin.
- Verify tax treatment, registrations and filing obligations for the products and markets you serve.
- Record the reason, effective date and exchange-rate assumption for every price change.
- Update your forecast to reflect revised prices, fees and expected sales volumes.
A disciplined pricing routine gives you more control over growth. It helps you spot margin pressure early, price each market with greater confidence and keep tax obligations visible without mistaking collected tax for business income.
