Refunds and delivery

Last updated 14 November 2026.

Delivery

This page covers books bought on this website, which are digital downloads: nothing is shipped. For a book bought in another store, that store’s delivery and refund rules apply.

• After you pay, you come back to a thank-you page, and Dodo Payments emails your receipt and a link to your download page, usually within a few minutes.
• The link in the email works for 30 days. After that, or on another device, the Dodo Payments customer portal sends you a fresh one: type the email you paid with.
• No email after an hour? Check your spam or promotions folder, then write to contact@proserviq.com from the address you paid with.

Refunds

Not happy with a book? Email contact@proserviq.com within 7 days of buying, from the address you bought with, for a full refund.

• The refund goes back to your original payment method through Dodo Payments. Banks usually show it within 5 to 10 business days.
• Once the refund is made, your download links stop working. A downloaded file cannot be taken back, so we ask you to delete your copies.

Printing

You get PDF files, not a printed book. You may print them for yourself; if you use a print shop, its prices and policies apply.
