Delivery is a Google Sheets copy link sent after purchase, plus a setup walkthrough. This is a planning tool, not accounting software or tax advice. Standard price planned at £29 after launch.
Checkout requires your express request for immediate digital delivery. Once delivery begins, the normal 14-day change-of-mind cancellation right is lost. Your rights if the product is faulty or misdescribed remain unaffected. Read the refund policy and terms.
