Never Miss a Return or Warranty

Automatic countdowns calculate the exact days remaining on store returns and manufacturer warranties, notifying you before windows close.

02

Smart On-Device Scanning

Scan paper receipts, warranty cards, product labels, and serial numbers. On-device vision suggests store names, dates, and model numbers.

03

Forever Proof of Purchase

Thermal paper receipts fade to illegible white within months. BillProof preserves high-res digital scans, serial tags, and purchase proof indefinitely.

REAL-WORLD SOLUTIONS

Built for real-world scenarios.

Whether you are protecting a deposit, organizing family appliance warranties, or managing property portfolios.

Homeowners & Families Appliances & Tools

Protect Major Household Investments

Track dishwashers, refrigerators, HVAC units, televisions, and lawn equipment. When an appliance malfunctions in month 11 or month 23, pull up the serial number and receipt in 5 seconds.

Tech & Gadget Enthusiasts Electronics Coverage

Laptops, Phones & Audio Gear

Keep AppleCare, standard warranties, and extended retail coverage organized. Never pay out-of-pocket for repairs or battery replacements that were covered under manufacturer warranty.

Active Shoppers Return Window Alerts

Stop Losing Money on Missed Returns

Bought clothes, shoes, or electronics you might return? Set 14-day or 30-day return alerts so you get notified in time to claim a full refund instead of store credit.

Freelancers & Small Studios Asset & Tax Records

Equipment Inventory & Tax Proof

Catalog cameras, microphones, monitors, and studio hardware with receipts and serial numbers. Export CSV logs for accountant tax depreciation and insurance coverage.

HOW IT WORKS

Four steps to complete proof.

Designed for speed on-site with zero unnecessary taps or complex setup.

01

Snap Receipt or Serial Tag

Photograph a store receipt, online invoice screenshot, product box label, or machine serial tag using the built-in scanner.

02

Set Coverage Duration

Choose from standard 14/30-day return windows, 1-year/2-year manufacturer warranties, or custom duration. BillProof calculates the exact cutoff date.

03

Receive Timely Alerts

BillProof monitors the timeline locally on your device and sends alert notifications before deadlines expire so you can act.

04

Export One-Tap Proof

When initiating a return, repair claim, or insurance filing, export a clean PDF dossier or CSV spreadsheet with receipts and serial numbers attached.
