Billing frequency
You can choose monthly or annual billing at checkout. Annual billing can save up to about 20% compared with monthly billing.
Payments and tax
Payments run through Stripe. Applicable tax is calculated and added at checkout when required.
Discounts and offers
PriceDNA runs offers from time to time. When one applies to you it is applied automatically and shown on the checkout summary before you pay, so there is nothing to enter and nothing to claim.
Checkout normally includes a box for a promotion code. When a discount has already been applied to your checkout the box is not shown, because the discount is on the order.
Cancellation
You can cancel anytime. Access continues through the paid period after cancellation.
Managing billing
Use Settings → Billing to manage your plan, billing details, and invoices.
