Features
Built for underground utility contractors
Estimating and bidding for water, sewer, storm, and civil work. The feature list is short on purpose.
Bid Proposals
Estimates organized by section and line item, with overhead, profit, bond, and tax markups rolled in. Export a clean bid PDF for the general contractor.
Plan Takeoff
A built-in PDF plan viewer with per-page scale calibration and pipe-run drawing. Takeoff quantities drop straight into your bid line items.
Trench Profiler
Excavation and backfill volumes from pipe size, depth, width, and bedding. The numbers feed your line items so you are not doing it twice.
Material Catalog
Material pricing with history, supplier price-sheet import via CSV, and 600-plus seed items for water, sewer, storm, gas, and fiber.
Crews & Labor
Crew templates with burdened labor and production rates, plus owned and rented equipment costs. Assign a crew to a line item and let it price.
Win/Loss Tracking
Record which bids you win and lose so your pricing sharpens over time. Duplicate old bids to start new ones, lock the winners, manage change orders.
Your data
Your work stays on your computer
BidSheet stores everything in a database file you own. No account required, no telemetry, nothing leaves your machine. If you would rather no bid data ever touch a server, turn on local-only mode and confirm it yourself with a packet capture.
- Runs fully offline, no signal required
- Open source under GPLv3, every line on GitHub
- Your database is one file on your disk, exportable any time
Optional cloud sync · Beta
Add backup and sync when you want it
$20/month · first 30 days free
Cloud sync adds encrypted backup, access from a second computer, and a way to get everything back when a laptop dies. It costs real money to run, so it costs money to use, and it funds the work. The app stays free either way, and your data still lives locally.
