Step by step
How RenewOS handles your warranty expiry reminder
- 1
Snap and store at purchase
The day you buy it: invoice photo, serial, price, warranty end date. Twenty seconds now, painless claims later. Attachments are private and never read by us.
- 2
The 60-day window
Most warranty issues surface well before expiry. The 60/30/7-day ladder gives you time to test the product thoroughly and file claims while it still counts.
- 3
Everything together, forever
The invoice, the dates and the history live on the item. Two years later, 'what did we pay for the washing machine?' is a search box away.
Questions
About the warranty expiry reminder
How big can attachments be?+
Up to 20 MB per file, in PDF, PNG, JPEG or WebP. Stored privately — downloads use signed, short-lived URLs tied to your session.
Can I track warranties for office equipment?+
Yes. Small businesses use workspaces with locations (which office, which floor) and custom fields (asset tags, vendor SLAs) on the Business plan.
Do warranties recur?+
Usually not, but extended warranties and AMCs do. Recurrence is fully adjustable — monthly to every 10 years.
