The problem
- Driving out with a wheel and a tape before every bid costs a morning.
- Turning feet into yards, tons, posts and bags by hand invites misses.
- Estimates built from memory leave out line items and margin.
- Signed jobs fall through the cracks between scheduling, invoicing and payment.
What it costs today:
- One missed line item on a slab or a sewer run can cost more than a month of this software.
- Hours spent measuring and retyping estimates are hours not spent selling.
- A lost completion date turns a simple warranty call into an argument.
How KardinalEye solves it
- Draw the job on 1-ft USGS aerial photos and get lengths, areas and counts right away.
- Depth, width and spacing turn them into cubic yards, tons, gallons, posts and panels.
- Price from your own book, materials and labor, with every number traced and a scope check.
- Send Good / Better / Best proposals they sign on screen, then track the job to paid.

How it works
- Open KardinalEye in a current browser on a computer or tablet. Once it's open it works offline.
- Enter your business license key. One key covers every user and device at your business.
- Add your company, logo and price book, then measure, estimate and send your first proposal.
- Back up with one click and buy a new key of 1 to 12 months when yours ends. Nothing renews automatically.
Licensing
One license per business: every user and every device at your business is covered, never per seat. Buy a 30-day key ($120), a 1-year key ($1,200), or any length from 1 to 12 months (5% off from 3 months, 10% off from 6). Each key is a single payment and does not renew automatically; you are never charged again unless you buy another key. Your key is emailed as soon as payment clears. Your data stays on your own devices: use the app's Backup button regularly.
