A warranty certificate is the document that proves what you promised a customer when they bought something — and for how long. A clear one prevents disputes later. At a minimum, a good warranty certificate includes:
Yes — completely. There's no signup, no watermark, and no limit on how many certificates you make. It runs entirely in your browser, so nothing you type is ever sent to us.
No account, no email required to use it. Fill in the form, click Print / Save as PDF, and you're done.
You don't have to. Enter the start date, pick a coverage length (30 days up to 5 years, or lifetime), and the generator fills in the end date automatically. Prefer to set it yourself? Choose “Custom” and type any end date.
Yes. Click “+ Add your logo” at the top of the certificate to drop in your business logo. It appears on the printed PDF and, like everything else, never leaves your device.
