Bidfident for electrical subcontractors
Estimating software for electricians
Pricing an electrical installation in Bidfident starts with what you already measure: metres of conduit and cable, and each socket outlet, light fitting and distribution board by number. Every line carries your electrician's hours per unit and the material with its waste. The scissor lift is charged only for the hours it runs, fire alarm quotes sit side by side, and supervision follows the programme.

Sound familiar?
Cable waste added as a guess
In a spreadsheet the extra for offcuts and drawing in is often a lump added at the bottom, or forgotten. In Bidfident each line of conduit or cable carries its own waste percentage, so the materials are right line by line.
The scissor lift priced for every hour
Light fittings go up off a scissor lift, but the lift isn't in use for every hour of the install. In Bidfident the plant on a line can have its own hours per unit, so it's charged for the time it's used.
Fire alarm quotes in three emails
The fire alarm subcontractor sends a quote, then a revised one, and the old figure stays in the spreadsheet. In Bidfident each package's quotes sit side by side, the lowest is flagged, and you carry the one you pick.
How Bidfident fits your work

Metres of conduit, outlets by number
Price conduit and cable by the metre, and socket outlets, LED panels and boards by number. Every line takes a quantity, the electrician's hours per unit, a material price with a waste percentage, and plant by the hour. Copy and paste, fill down and undo work like Excel.

A higher rate for the board work
Setting and terminating a distribution board may need your most experienced electrician. Give that line its own rate and it's marked in purple, while the rest of the job stays on the electrician's library rate.

The scissor lift for the hours it runs
Give the lift on the light fitting line its own hours per unit, say half an hour for each panel, and it's charged for that time, not for every hour the gang spends on the line.

Fire alarm quotes side by side
Enter each fire alarm or data cabling quote, see the lowest flagged, and carry it or the one you pick. Waiting on quotes? Carry an allowance until they arrive.

Your accessories and fittings, found as you type
Keep sockets, light fittings, cable and conduit in the company library with their prices and hours per unit. Type a description and the line picker finds them, or an assembly that fills a whole line at once.

Supervision that follows the programme
A part-time supervisor by the week follows the job duration, so a 10-week programme that grows to 12 picks up two more weeks. Temporary lighting and power can go in as a lump sum.

Questions
Can I price conduit by the metre and outlets by number?
Yes. Units are free text, so m, nr and item all work. Bidfident doesn't convert between units, so price each line in the unit its rate is in.
Can the board work carry a different rate from the rest of the job?
Yes. Give that line its own rate. It's marked in purple so anyone checking the estimate can see it.
Can I keep electrician and apprentice rates apart?
Yes. Set a rate per trade in the library, such as Approved electrician and Apprentice, and give each line the trade that does the work. Type a new trade in the Trade cell to add it with its rate.
Can I see the containment and wiring floor by floor?
Yes. Tag each conduit, cable and fittings line with an area or location, such as ground floor and first floor, and group the sheet by it with a subtotal for each.
Does it count fittings from the drawings?
No. Bidfident doesn't read quantities from drawings. Type your counts in, or paste them into the sheet from a spreadsheet or your bill of quantities.
What if the electrician's rate goes up after I submit a tender?
A submitted tender keeps the electrician's and scissor lift's rates it was priced with, so a change to your library doesn't move a price you've already sent.
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.
