Recommended approach: Use fixed pricing for components and services with a known cost.
Check before launch: The browser total is a responsive preview. Server verification and Shopify checkout remain authoritative.
Check before launch: Test discounts, quantity, taxes, and presentment currencies before launch.
Choose the correct pricing mode
Pricing modes express different business rules. Mixing them without a deliberate sequence can make a correct formula appear surprising to a merchant or customer.
| Mode | Behavior | Example |
|---|---|---|
| Fixed | Adds a set amount | Premium leather +$40 |
| Percentage | Adds a share of the base price | Rush service +10% |
| Override | Sets a new configured base | Large model becomes $499 |
| Surcharge | Adds an amount when a rule matches | Oversize handling +$25 |
Common questions
Can a customer change the submitted price in the browser?
Aura does not trust a client-submitted total. The server and Shopify checkout functionality validate the selections and authoritative price.
