App Description
You're at the homeowner's kitchen table with a tape and a folder of glass options. Sashline is the opening sheet that turns that walk-through into a whole-house number before you get up from the chair. Rough in each window and door as its own priced line, and the house draws and totals itself as you go β no missed openings, no napkin math, no money left on the table.
WALK THE HOUSE, ROUGH IN EVERY OPENING
Capture each window or door as one opening on the board: rough-opening width by height with the install allowance auto-applied, operating style (double-hung, casement, slider, patio door, entry, French), the glass-and-frame package (Low-E, argon, grid, finish), and install scope (retrofit or full-frame). Every opening draws itself head-on as a to-scale elevation, so the sheet reads the house as real openings, not an anonymous list.
THE WHOLE-HOUSE ROLL-UP THAT STACKS AS YOU GO
The title-block at the foot of the board re-rolls live: openings counted, running daylight area, and the whole-house subtotal. Add an opening and the number moves with it. Nothing is guessed and nothing is forgotten β the openings you measured are the openings you priced.
GOOD-BETTER-BEST IN ONE TAP
The free tool prices one package. Turn on good-better-best and one tap re-prices the entire board β flip the whole house from Low-E to triple-pane and every per-opening price and the whole-house subtotal re-ink together. That's the spread the homeowner signs at the kitchen table, not a number you have to redo in the truck.
OPERATING STYLES, SPEC'D RIGHT
Double-hung, casement, slider, awning, picture, patio door, entry, French β each style carries its own elevation glyph and its own glazing options, because a picture window doesn't price like a patio door. The rough-opening allowance is applied for you, so the size you quote is the size that fits.
MEASURED TO SIGNED
Move every house down the board: measured, quoted, good-better-best, signed. See the state of the board at a glance β openings drawn, houses quoted, this month's signed β so you know which kitchen tables still owe you a close.
THE ELEVATION ABSTRACT
On-device insights read the whole board: close rate, openings per sale, price per opening, the good-better-best tier mix, and a list of any opening still missing a glass-and-frame package, so nothing ships un-priced. Every number stays on your phone.
