Bidfident for drywall contractors
Estimating software for drywall and ceilings
Drywall and ceiling contractors price in square feet and linear feet, and Bidfident lets you do the same. Framing, board on both sides, taping by a taper at their own rate, ceiling grid with a scissor lift that runs less than the crew, and bulkheads by the foot. Waste bins go in by the number emptied, and the foreman follows the schedule.

Sound familiar?
Taping priced at the hanger's rate
When everything sits on one labour rate, the taping is priced like framing and the bid is off. In Bidfident each line takes its trade's rate, so the taper and the installer are each priced at their own.
Board waste added in your head
Ten percent on board, five on studs, all worked out at the end. In Bidfident each line carries its own waste percentage, so the material is right line by line.
Floors that don't add back to the total
Three floors on three tabs, and a change on one never reaches the summary. Bidfident groups one estimate by floor or area with subtotals, and it all adds up to the cent.
How Bidfident fits your work
Installers and tapers at their own rates
Give the framing and board lines the installer's trade and the taping line the taper's, and each takes its rate from the library. Add a new trade in the Trade cell without leaving the sheet.
Square feet and linear feet, line by line
Studs, board and ceiling tile by the square foot, bulkheads by the linear foot. Each line takes a quantity, hours per unit, a material price with a waste percentage, and equipment by the hour.
Floor by floor, with subtotals
Tag each line with a floor or area and group the sheet by it, with a subtotal for each. Collapse the groups to see all three floors at once.
Change a whole floor at once
Tick the lines for level 2, then set their area, trade or equipment on all of them in one go. The totals for just the ticked lines show as you pick them.
The lift on the ceiling line only
The scissor lift on the ceiling grid gets its own hours per square foot, so it's charged for the time it's used, not every hour the crew is on the line.
Insulation bids side by side
Enter each bid for acoustic insulation in the partitions, see the lowest flagged, and carry it or the one you pick. No quote yet? Carry a plug amount.

Questions
Can I price in square feet?
Yes. Units are free text, so sf, lf, m² and ea all work. Bidfident doesn't convert between units, so price each line in the unit its rate is in.
Can taping have a different rate from hanging?
Yes. Set up a taper as its own trade with its own rate, and give the taping line that trade. Each line then takes its trade's rate.
Can I build a partition type as one line?
Yes. Save it in the rate library as an assembly, such as a framed and boarded wall. Pick it from the line picker and it fills the whole line at once.
Can I price each floor separately?
Yes. Tag each line with an area or location, then group the sheet by it to see a subtotal for each floor.
Does it measure walls from the drawings?
No. Bidfident doesn't read quantities from drawings. Type your square feet in, or paste them from a spreadsheet.
Can waste bins go in by the number emptied?
Yes. Add them as an overhead item priced each, and type the number of bins you expect to fill. They land in the bid, but don't change when the job duration does.
Does Bidfident work with Claude or ChatGPT?
Not yet, but it's coming. You'll be able to connect Bidfident to your own Claude or ChatGPT account and ask about your estimates in plain English. The answers will come from Bidfident's own figures, so they match the estimate. It will use the account you already have: Claude first, ChatGPT to follow.
